FOREWORD
1. SCOPE OF MANUAL This manual contains information for the installation, operation, and maintenance of the Communications
System Analyzer. 2. PURPOSE AND USE
The Motorola Communications System Analyzer is a portable test instrument, designed specifically for the service and monitoring of communications equipment. Its functions supersede those of a Service Monitor, expanding the features and capabilities to the point wherein servicing is achieved with a single instrument, rather than a host of separate equipmen'i.
The R2001A is the standard Communications System Analyzer. The R2002A Analyzer, which contains the IEEE-488 Standard interface control bus, is also available. Programming for the R2002A is covered in Seeton 21 of this manual.
The Analyzer improves a technician's efficiency and accuracy and reduces servicing time. The Communications System Analyzer performs the functions of signal generation, signal monitoring. and the tests normally associated with the devices listed below.
· Spectrum Analyzer · Duplex Generator · Modulation Oscilloscope · Frequency Counter · AC/DC Digital Voltmeter · RF Wattmeter · General Purpose Oscilloscope · Multi-Mode Code Synthesizer · SINAD Meter · Sweep Generator
The Analyzer meets the shock and vibration requirements of EIA test RS152B, the same specifications met by Motorola mobile radios. This minimizes failures when the instrument is used in a mobile service van, and means it is as tough as the radios it services.
The Communications System Analyzer is designed to be serviced quickly and easily, should a breakdown occur. The majority of the circuitry is on seven modular plug-in circuit boards which have built-in test points that aid in isolating the problem to a specific board. Simple plug-in replacement gets the instrument back in service.

I
2-2. The Communication System Analyzer is a portable test instrument designed for servicing and
monitoring of portable, mobile, and land base communications equipment operating over the frequency range
of 1 MHz to 1 GHz. The unit performs the functions of signal generation, frequency error and modulation
measurement. It is also capable of a variety of tests normally associated with the following devices:
Spectrum analyzer Duplex offset generator Modulation oscilloscope Frequency counter AC/DC digital-analog voltmeter RF wattmeter General purpose oscilloscope Multi-mode code synthesizer SINAD meter Sweep generator
2-3. MICROPROCESSOR. A Motorola M-6800 series microprocessor permits keyboard entry of data, autoranging of displays, fast frequency access, and permanent storage of often-used frequencies and codes. Generate and monitor RF frequencies, tone codes, and timing sequences can be programmed into a nonvolatile memory, saving time and eliminating entry errors. When one particular type of equipment is continuously serviced, the unit can be programmed to select the mode of operation required when first turned on. 2.4 DISPLAY. All functions, generated or monitored, are presented on an 8 cm x 10 cm cathode ray tube (CRT) in both analog and digital format, with the name of the function being displayed. The CRT also displays control settings eliminating the need for operator search of different equipment panels. Digital readouts are visually aided by the use of the continuously autoranging analog line segments, which are similar to a bar graph. Each has a base line and calibration markers, in addition to the intensified segment showing the measurement. The user selectable displays are listed in a column beneath the DISPLAY heading on the front panel. Choosing a display is accomplished by pressing an arrow button below the column, for up or down movement, as required. When the appropriate arrow is pressed, the LED adjacent to the selected display illuminates. FUNCTION is selected in the same way, providing rapid, accurate changes in service capability at the touch of a button.
2-5. SYSTEM WARNINGS. To aid the technician in servicing, visual warnings will appear on the CRT when certain overload or caution conditions exist. Displays warn of low battery power, overheating of the RF load, or an improper attenuator setting for particular measurements. In addition, a continuous audible alarm sounds when a preset deviation limit is exceeded in monitor modes. This limit is entered by using the keyboard and may be programmed from 0 kHz to 99.9 kHz, with 100 Hz resolution.
2-6. FUNCTIONS. The following paragraphs briefly describe the major functions of the Communications System Analyzer.
2-1
2-7. AM, FM, CW, DSB Signal Generation. The built-in general purpose signal generator provides continuous coverage of the HF, VHF, and UHF land mobile spectrum for receiver testing. Many forms of external and internal modulation can be simultaneously impressed on the carrier signal for actual composite signals. The frequency range of the RF signal generator is from 10 kHz to 1000 MHz in 100 Hz steps. The output of up to 1 Volt rms provides sufficient amplitude to get through misaligned tuners and receivers, and is especially effective when changing a receiver's frequency. The high level, clean output is available over the entire frequency range of the Communications System Analyzer. The output frequency is referenced to an internal time base which can be calibrated to the WWV Standard. (See paragraph 4-7.)
2-8. Simultaneous Modulation. Modulation is simultaneously available from an internal 1 kHz tone
generator, a multi-mode code synthesizer, and from external inputs. The external modulation can be voice
from a standard Motorola mobile radio microphone (which plugs into the front panel of the instrument), as well as a signal applied to the external BNC input. Separate controls are provided for independently setting the
I ·~
levels of the 1 kHz tone, the code synthesizer, and the external modulation sources. The 1 kHz test tone is a
convenient source of modulation for making SINAD measurements. A MOD OUT connector provides external
access to all of the modulation signals.
2-9. Modulation Display. The recovered audio waveform, or audio used to modulate the generator carrier, can be viewed on the CRT. It is used to graphically measure deviation, and to aid in waveform analysis.
2-10. Sweep Generation. The sweep generator mode provides an RF output that is swept in frequency across a band centered at the programmed frequency. A synchronized horizontal sweep for the internal oscilloscope allows filter characteristics to be easily determined. This is ideal for in-depth troubleshooting of IF amplifiers and filters.
2-11. SINAD Metering. A comprehensive check of receiver performance can be made with a SINAD measurement. The analog line segment and digital representation of SINAD appear automatically whenever the unit is in the normal generate mode. The only hookups required are from the Communications System Analyzer to the RF input of the receiver under test, and from the audio output of the receiver to the instrument's multipurpose input. The measurement, and appropriate servicing, can then be accomplished without the need for a separate signal generator, SINAD meter or distortion analyzer.
2-12. Multi-Mode Code Synthesizer. The Communications System Analyzer generates Private Line tones (PL), Digital Private Line codes (DPL), two-tone sequential paging codes and tone-remote base signaling tones. All codes are available at the Mod Out jack, as well as being used internally to modulate the RF signal generator. This eliminates the necessity of using separate generators and oscillators for general servicing, setting transmitter deviation, or for checking tone-remote-base control lines. Timing sequences are also stored in the Tone Memory to provide fast set-up and eliminate errors. User programmable timing sequences are also provided to allow the storage of non-standard or future time sequences.
2-13. Off-the-Air Monitor. The 1.5 µ V sensitivity of the Communications System Analyzer receiver allows
off-the-air monitoring and measurement of transmitter frequency error and deviation to 1000 MHz. A variable squelch allows weak signals to be monitored, but can be set higher to ensure the proper signal-to-noise ratio for measurement accuracy. The off-the-air monitor function enables frequent parameter checks without leaving the shop, thus spotting system degradation early and keeping service costs down. Bandwidth can be set Wide for off-channel signal location or wide band FM; or Narrow for maximum sensitivity and selectivity.
2-14. IF Display. When the IF display mode is selected, the Communications System Analyzer's receiver IF envelope is shown on the CRT. This allows the technician to qualitatively and quantitatively assess the amplitude modulation envelope of a transmitter.
2-2
2-15. Spectrum Analyzer. In this mode of operation the CRT displays a window of the RF spccti'Um whose bandwidth (from 1 MHz to 10 MHz) is determined by the DISPERSION/SWEEP control. The center frequency of this window ranges from 4 MHz to 1,000 MHz, selectable by entering a specific center frequency with the keyboard. This center frequency is digitally displayed at the top of the CRT screen, eliminating the need for an external signal generator, and counter to provide markers. Once a signal is centered on the screen, positive identification is aided by switching the Analyzer to MONITOR AM or FM and listening to the demodulated output via the built-in audio amplifier and speaker. The spectrum analyzer's center frequency can be scanned up or down at rates varying from 0.5 kHz per second to 5 MHz per second, using the RF scan control. Slow rates are used to precisely determine a subject signal's frequency while faster rates are used for locating intermittent transmissions or viewing large areas of the spectrum in a short time. Uses of the Spectrum Analyzer are: Intermodulation interference identification, IF and RF signal tracing, transmitter harmonics measurements, transmitter spurious checks, and receiver local oscillator radiation.
2-16. RF Burnout Protection. At RF input levels above 200 mW, in any operating mode, the input automatically switches to the internal 125 watt RF load, thus protecting the attenuator and signal generator against damage from a keyed transmitter. If power above 200 mW is applied in any mode except the power monitor mode an audiable alarm sounds and a visual warning on the CRT directs the operator to switch to the power monitor mode.
CAUTION
To prevent undue stress on the protected circuits it is advisable to always switch the system to the power monitor mode before applying power in excess of 200 mW. Additional protection is also obtained by making it a practice not to leave the step attenuator in the 0 dB position.
2-17. Terminated RF Power Measurement. RF power is automatically measured when the Communications System Analyzer is in the Power-Monitor mode. The built-in RF load dissipates up to 50 watts for three minutes and up to 125 watts for one minute. If a high power transmitter should be keyed into the unit for a time long enough to threaten overheating of the power measuring circuitry, the audible alarm sounds and the CRT display changes to read "RF LOAD OVER-TEMP," thus warning the technician to un-key. This instrument function is further enhanced by the simultaneous indication of RF power output, carrier frequency error, and modulation, all on the sarne CRT display.
2-18. In-Line Power Measurement. Use of the Motorola ST-1200 series Wattmeter elements in conjunction with the analyzer's external wattmeter display provides measurement of forward and reflected antenna power on the CRT display. This capability eliminates the complex hook-ups and the additional instruments normally required for antenna measurements.
2-19. Duplex Generator. In this mode, the Communications System Analyzer simultaneously receives and generates the signals for duplex radio servicing, while generated and monitored frequencies are observed on the CRT. In the 0-10 MHz range, the 'Freq. Set' control tunes the proper offset frequency for the VHF and UHF bands. The 45 MHz mode provides a single offset forthe 800 MHz range. A switch is also provided to select high or low side offset, as required. The Duplex Generator provides enhanced capability to service equipment such as repeaters, car telephones and Emergency Medical Telemetry portables.
2-20. 500-kHz Oscilloscope. This general purpose scope is ideal for waveform analysis in two-way communication servicing. Use it for viewing modulation signals (either internally or externally generated), detection of asymmetric modulation or audio distortion, and general purpose signal tracing and troubleshooting.
2-3
2-21. Frequency Counter. The frequency counter measures inputs in a range from 10 Hz to 35 MHz. Its 5 digit auto-ranging output is displayed on the CRT and allows precise measurement and setting of offset oscillators, 35 kHz and 455 kHz pager IF's, PL frequencies and other external input signals. This function will also operate simultaneously with the generate or monitor receiver modes of operation. Frequency measu rement of transm itted carriers and other signals higher than 35 MHz is easily accomplished with the frequ ency error readout in the monitor modes.
2-22. AC/ DC Voltmeter. Switching to the DVM mode provides a digital-analog voltage presentation on the CRT, al ong with the corresponding dBm value. The auto-ranging display provides full scale deflecti ons of 1, 10, 100 and 300 Volts . AC or DC measurement is selected on the CRT . The meter's wide dynam ic ra nge and three digit display are ideal for setting power supply voltages, checking bias levels, and setting audio levels. Like the Frequency Counter, the DVM will operate simultaneously with generate or monitor operation .
2-23. Power Supply. The Communications System Analyzer may be powered by a variety of sou rces:
· AC at 110 or 220 Volts, 50/ 60 Hz · DC from an exte rnal 12 Volt source such as a service vehicle · DC from an optional battery pack. Servicing can thus be accomplished wherever the equipment under
test is located

4-5. OPERATION
4-6. The operator may use the CRT display to become familiar with the functions the Communication System Analyzer is capable of performing. The unit may be preset to any of the functions the unit performs. As a function and its parameters are selected they are displayed on the CRT.
The unit contains a nonvolatile memory that stores frequently used data for fast access, reducing setup time. As a function is selected, if data for that function is stored, the data is displayed on the CRT.
One of the stored parameters may be used or the user may manually select (keyboard entry) the parameters required for the function. Selection of stored data or keyboard entry of data is cursor controlled, As a control is changed the CRT display changes to reflect the new parameter being used or function being performed.
4-7. CALIBRATE. The Communication System Analyzer may be calibrated to WWV or other time/frequency standards (figure 4-4). To calibrate the unit's time base (frequency standard) proceed as follows:
a. Connect antenna to RF In/Out connector.
b. Set FUNCTION switch to Monitor and DISPLAY to Gen/Mon Mtr.
c. Enter frequency of time/frequency standards station directly from keyboard.
4-12
d. Select AM function.
e. Using a tuning tool, adjust time base frequency calibration control (on left side of housing) until CRT frequency error display indicates less than 5 Hz error. Frequency settability to 0.5 part per million can thus be achieved using a 10 MHz frequency standard station.
NOTE
The time base output is also available on the rear panel for external measurement or laboratory calibration to better than the 0.5 ppm achievable with the above method
NOTE
An external time base input is also provided on the rear panel.

4-8. GENERATOR OPERATION. The system generates RF frequencies for FM, AM, CW, SSB, and DSBSC types of transmission covering a range of 10 kHz to 1000 MHz. To generate a signal the FUNCTION switch is placed in the Gen. position.
NOTE
An RF protection circuit to protect against damage due to inadvertent application of RF power to the unit, when in a generate or sensitive monitor mode, is functional over the full monitor frequency range of the equipment (2 to 1000 MHz).
The type of signal is selected using the FUNCTION select LED indicator column. The unit can deliver an output of up to 1 volt into 50 Ohms. When in the AM generate mode the variable control (located in the RF SECTION on the front panel) should not be set above the AM limit mark. Exceeding this may cause distortion in the output.
4-13
NOTE
The RF protect circuit may trip if generator is run at full power output without having a 50-ohm load connected.
4-9. DUPLEX GENERATION. When operating in the duplex generate mode the offset frequency can be set to either 45 MHz or 0 to 10 MHz (adjustable). The lmage/Dplx switch sets the offset frequency above (high) or below (low) the monitored frequency. When offset is in the 0 to 10 MHz range, the control range may include a fold back region. If the generator is operated in this foldback area erroneous frequency output indications can be given. Avoid areas where backward indication or a jittering display of the offset frequency are incurred. The following is an example of the duplex generator being used to setup repeater levels.
a. Connect DUPLEX GEN output to repeater receiver antenna input and repeater transmitter signal sample to RF In/Out connector. The Duplex Gen Output level is fixed at -30 dBm nominal.
b. Set FUNCTION switch to Gen and DISPLAY to Duplex Gen.
c. Select Duplex Monitor frequency (repeater transmit frequency) from memory table or enter directly from keyboard.
d. Set DUPLEX GENERATOR frequency to repeater receiver frequency.
e. Adjust PL and test tone deviation to desired level on display.
f. Set FUNCTION switch to Monitor and measure the deviation of the repeated signal.
NOTE
Switch function to power monitor and connect repeater transmitter (under 125 watts) directly to the RF In/Out connector to read power and frequency error, as well.

4-10. FREQUENCY COUNTER. The frequency counter measures inputs in a range from 10 Hz to 35 MHz. The input to the frequency counter is through the Vert/Sinad/DVM/Counter in, BNC connector (located in the OSCILLOSCOPE section of the front panel). The counter sensitivity is controlled by the scope Vert switch. The following shows the minimum sensitivity for each switch setting:
Switch setting
0.01 0.1 1.0 10.0
- Sen- sitiv-ity
50 mV RMS 500 mV RMS 5V RMS 50V RMS
The autorange output of the counter is displayed on the CRT to a resolution of 0.1 Hz or 5 digits.
NOTE
Do not connect transmitter directly to the frequency counter input. Instead use the RF In/Out connector and the frequency error meter for transmitter frequency measurements.
4-11. SPECTRUM ANALYZER. Input to the spectrum analyzer is through the RF In/Out connector. Select the spectrum analyzer position on the DISPLAY column. Place the FUNCTION switch in the monitor position. Select the desired width of sweep by the Dispr/Sweep control. The center frequency is selected from the memory or entered directly from the keyboard, it is displayed at the top-right of the CRT. The following is an example of locating the frequency of an incoming signal with the spectrum analyzer.
a. Connect antenna to RF IN/OUT connector.
b. Set FUNCTION switch to Mon. and DISPLAY to Spect. Analyzer.
c. Select center frequency from memory table or enter directly from keyboard.
d. Adjust Disp/Sweep control for desired spectrum span.
e. Adjust Step attenuator i,f required to reduce sensitivity.
f. To determine whether a given displayed signal is valid or being internally generated, flip the lmage/Dplx switch to the opposite position. If signal moves in frequency or disappears, it then/represents an internally generated spurious response or received image.
g. Use the RF Scan control to move desired signal to center of the screen. If the signal is located to the right of screen center line, move the RF Scan control clockwise into one of five positive stepping modes. If the signal is to the left of screen center line, turn the RF Scan control counter clockwise to one of five negative stepping modes.
h. Adjust Dispr/sweep control fully counterclockwise for 1 MHz spectrum span.
i. Again use RF Scan to recenter signal on screen.
j. Set DISPLAY to Gen/Mon Mtr.
k. Now adjust the RF scan control to minimize any existing frequency error between the incoming signal and the Monitor frequency.
4-15
I. The frequency indicated at the top of the screen is now that of the desired incoming signal. It can also be monitored for call signs, etc.
NOTE
The spectrum analyzer is functional but uncalibrated for level measurements in Power Monitor mode for tr.ansmitter testing with the built-in 125 watt 50 ohm load. (Observe "RF LOAD OVERTEMP" warning for high power levels or extended periods of use.)

4-12. MONITOR. The analyzer is capable of monitoring the same frequencies that it generates (para 4-9). Select Gen/Mon Mtr in the DISPLAY column and the modulation type in the FUNCTION column. Set the FUNCTION switch to the Monitor position for small signal samples or off the air monitoring. For high power signal monitoring (0.2w to 125w), set the FUNCTION switch to Pwr Mon.
CAUTION
To prevent undue stress on the protected circuits it is advisable to always switch the system to the power monitor mode before applying power in excess of 200 mw. Additional protection is also obtained by making it a practice not to leave the step attenuator in the 0 dB position.
NOTE
High-powereo equipment in the 1-30 MHz range, which has unusually fast carrier rise times, may damage the system analyzer with repeated activation of the protect circuit. Ensure the FUNCTION switch is in the Pwr Mon position (this enables the protect circuit) before RF power is applied to the equipment.
In the monitor mode the CRT displays the type of signal being monitored, the selected frequency, power, error of the received frequency, and the modulation level.

4-13. EXT WATTMETER. When the analyzer DISPLAY is set to the Ext Wattmeter mode and the Motorola RTL-4055A in-line wattmeter adapter (supplied) is connected to the Ext Wattmeter jack the analyzer measures both forward and reflected power. The power rating of the wattmeter elements (Motorola ST-1200 series*), to be used, are displayed on the CRT. The following is an example of a test setup for external wattmeter operation. Figure 4-7 shows the test set connections and CRT display.
a. Select the EXT Wattmeter function by means of the arrow keys located below the DISPLAY column.
b. Plug the connector of the RTL-4055A In-Line Wattmeter adaptor into the "Ext-Wattmeter" jack located on the RF SECTION of the front panel.
c. Using the keyboard; enter the single digit which corresponds to the full scale power rating of the ST1200 series element you plan to use.
d. Place the ST-1200 element in the In-Line Wattmeter adaptor and install element/adaptor assembly into transmission line.
NOTE
Arrow on In-Line Wattmeter Adaptor must point in the forward direction of the desired rf power flow through the adaptor.
e. Key transmitter and observe magnitudes of forward and reflected power as displayed simultaneously on the 2 analog meter bars and corresponding digital readouts.

5-16. THEORY OF OPERATION
5-17. General
5-18. The operation of the Communications System Analyzer can be divided into nine basic functions: Generate, Power Meter, Monitor, Duplex Generator, Code Synthesizer, Frequency Counter, Digital Voltme1er (DVM), Oscilloscope, and Sinad Meter. The general operation of the unit will simultaneously incorporate the basic functions to provide the total capability of the system.
5-19. The following discussion will cover the block diagrams for each of the basic functions plus a discussion on the processor control of the system. A functional block diagram of the total system is shown in figure 5-3. Only the major signal paths between each of the modules are shown to clarify the total system configuration.
5-20. System Control
5-21 . System Control is the primary responsibility of the internal microprocessor. Front panel control and system status inputs to the processor are manipulated by the processor to provide the contro l for the operating mode. From the front panel the processor monitors the keyboards, the function select switch , the modulation control switch. the RF scan switch , the image switch , the bandwidth switch, the horizontal and vertical range switches, and the step attenuator switch. This information plus internal status information causes the processor to display the appropriate information on the CRT to program the center frequency, to set up the generate or monitor mode, and to make the internal switching arrangements for the selected operating state.
5-22. The interface to and from the microprocessor is via the processor bus. This bus consists of a 16-bit address bus, an 8-bit data bus, and a 7-bit control bus. This bus interfaces the processor to its program memory (ROM), scratch pad memory (RAM), IEEE interface, and the peripheral interface adapters (PIA). The PIA is the mechanism by which the processor interfaces with the system . A PIA consits of a dual 8-bit latch which may be programmed as either an input or output for the microprocessor. System input and control information passes to and from the microprocessor via three system control buses attached to a PIA.
5-23. Each system control bus consists of a 4 bit address bus, a 4 bit data bus, and an enable line. The 4 address bits determine which of 16 possible latches the 4 bits of data is to be sent to or received from. The enable line triggers the actual transfer of data. The three control buses within the system are called the RF control bus and the AF contro l buses 1 and 2. The RF control bus is as described above while the AF control buses consist of a single 4-bit address and 4-bit data bus and two enable lines. The resulting total input/output capability for the system buses is 16 latches at 4-bits each times 3 buses or 192 bits . A tabulation of buses and the controlling or input function of each bit is shown in table 5-2.
5-24. Systems with the IEEE remote control option interface the IEEE bus to the processor bus through a general purpose interface bus adapter (GPIB ) on the IEEE interface module. When enabled all control inputs to the system pass through the IEEE bus and front panel controls are ignored. For more information on IEEE control see section 21 .
5-25. Generate Mode
5-26. The generate mode provides a variable level RF output that is phase locked to the internal 10 MHz standard. AM, FM , and Sideband Modulation are possible on the output signal. A block diagram of the generate mode is shown in figure 5-4.

Figure 5-4. Generate Mode Block Diagram
5-27. The Frequency Standard module (A13) contains a 10 MHz standard oscillator with buffering and switching to provide a 10 MHz signal to the EXTERNAL 10 MHz OUTPUT and to the RF Synthesizer (A5). A provision is made for the application of an EXTERNAL 10 MHz INPUT which causes the internal standard to shut down and the EXTERNAL 10 MHz INPUT to be switched to the EXTERNAL 10 MHz OUT and to the RF Synthesizer.
5-28. The 10 MHz standard input to the RF synthesizer is digitally divided down to provide SYSTEM REFF FREQUENCIES for the frequency counter, the zero beat detector, the second local oscillator in the receiver, and the processor timing reference. Additionally reference frequencies are provided for a fixed 550 MHz locked loop and for a programmable 500 MHz-1000 MHz locked loop. The programming of the 500 MHz-1000 MHz locked loop is provided by the RF CONTROL BUS from the processor. The SELECT SWITCH selects one of three possible output points for the SYNTH RF output signal. The first is from the 500 MHz-1000 MHz loop directly. The second is from a divide by two on the output of the 500 MHz-1000 MHz loop which gives frequencies from 250 MHz to 500 MHz. For outputs below 250 MHz, the output of the 500 MHz-1000 MHz loop is mixed with the fixed 550 MHz signal and the difference signal used for the output. For this output the processor programs the 500 MHz - 1000 MHz loop for frequencies between 550.01 MHz and 800 MHz to obtain outputs from 10 kHz to 250 MHz respectively.
5-29. FM and SWEEP Modulation is implemented within the 500 MHz-1000 MHz loop. FM capability is 200 kHz peak which when divided by two gives the 100 kHz peak requirement. Similarly the sweep capability is 10 MHz peak which provides the 5 MHz requirement for the sweep generator and spectrum analyzer req u i reme,nts.
5-12
5-30. The SYNTH RF signal is amplified and leveled in the RF Input module (A11 ). The signal level at the output of the wideband amp is detected and compared to the AM MOD & DC REF signal from the front panel level control. If there is a difference between the two signal levels, the ALC amp provides an error voltage. The error voltage controls the attenuation of the Voltage Controlled Attenuator (VCA) in the direction that will make the detected RF output equal to the AM MOD & DC REF signal. The;·e are two possible VCA's for the output leveling. The VCA within A11 is used for frequencies from 1 MHz to 1000 Jv1Hz. For frequencies below 1 MHz, the VCA on A 11 is set to minimum attenuation and the VCA on the RF Synthesizer module is used for leveling. Amplitude modulation is incorporated by suming the modulation signal with the DC reference signal to force the leveling loop to vary the output level in proportion to the modulating signal. The signal from the RF level detector (CARRIER+ MOD LVL) is used by the processor for the determination of RF output level and the percent AM. The leveled output range of the Wideband Amp is from -3 dBm to+ 13 dBm (0.16 to 1.0 Vrms).
5-31. The leveled output from the Wideband Amplifier is applied to the Generate/Monitor (T/R) switch. For AM, FM, and CW signals the switch connects the amplifier output to the Step Attenuator. For Double Sideband Suppressed Carrier (DSBSC) the T/R switch is in the "R" position where the amplifier output is connected to the local oscillator port on the receive mixer and the attenuator is connected to the RF port. The DSBSC MOD signal is then used to drive the IF port of the mixer giving a DSBSC signal at the RF port and thus at the Step Attenuator.
5-32. Coarse level control in 10 dB increments is provided by the Step Attenuator. The total range of the attenuator is from 0 dB to 130 dB attenuation. For the basic R2001 A the Step Attenuator is controlled directly by a shaft to the front panel knob. With the IEEE control option the Step Attenuator is electrically programmable and controlled by the processor. The front panel knob in this case is connected only to a rotary switch which directs the processor in setting the attenuation level. Under IEEE control, commands via the IEEE bus determine the attenuator setting. (See section 21.)
5-33. The RF signal from the Step Attenuator passes through the input protection circuitry to the RF Output jack. A level detector on the RF Output jack monitors the power level at the jack. If power in excess of 200 mW is applied to the Output jack, the protection circuit will activate and switch the RF Output jack to the internal 50 ohm load. This action protects the Wideband Amp and Step Attenuator against burnout. A signal line from the protection network signals the processor that the system is in the protected mode. The processor in turn activates the CRT and alarm warnings.
5-34. Power Meter
5-35. Input power measurements are made with the RF Input terminated into an internal 50 ohm load. This termination is the same one used for the protect mode when in the generate or monitor functions. A block diagram of the power meter is shown in figure 5-5.
5-36. For the power meter mode the processor sets the WATT METER ENABLE line to cause the RF input jack to be switched to the 50 ohm power termination. For modes other than the power meter, an Input Detector on the RF Input jack detects when the input power has exceeded 200 mW and then switches the input to the load.
5-37. The switch is a single pole double throw configuration so that when switched to the RF load the path to the Step Attenuator and Converter is open circuited. However, leakage across the open switch provides sufficient signal for operation of the normal monitor functions.

5-38. A sample of the RF voltage being applied to the RF Load is detected by the Power Detector to give a DC output proportional to the peak RF voltage. The amplifier following the detector buffers and gain adjusts the detected voltage to provide the RF INPUT POWER signal to the processor. The processor then determines and displays the RF input power.
5-39. A Temperature Sensor located near the flange of the RF Load alerts the processor when the load temperature exceeds 80° C. The processor reacts to the OVER TEMPERATURE signal by displaying a warning message on the CRT and by sounding the audible alarm.
5-40. Monitor Mode
5-41. The monitor mode allows RF signals from an antenna or from a transmitter directly to be checked for frequency error, modulation level, and spectral content. AM, FM, and sideband modulations can be accommodated with this system. A block diagram of the monitor mode is shown in figure 5-6.
5-42. The RF signal to be monitored is applied to the RF Input jack on the RF Input module (A 11 ). If the input level is less than 200 mW the input signal passes directly through the Input Protection circuitry to the Step Attenuator. For input levels greater than 200 mW the protection circuit switches the input to the internal load and signal the operator to switch to the Power Monitor mode. In this case, RF leakage (paragraph 5-37) through the protection circuits provides the input signal to the Step Attenuator.
5-43. For the monitor mode the T/R switch is set so that the RF input from the Step Attenuator is connected to the RF port on the receive mixer. The output from the wideband amp is switched to the local oscillator port on the receive mixer. The processor programs the RF Synthesizer for an output frequency that is offset from the frequency to be monitored by 10.7 MHz. The offset may be above or below the center frequency as selected by the front panel image switch.

5-44. The 10.7 MHz difference signal at the IF port of the receive mixer is amplified and selected by the first IF Amplifier and Filter. The Amplifier provides sufficient gain so that the overall gain of the RF Input module is 10 ±2 dB. The IF filter provides a modulation acceptance bandwidth of ±100 kHz. The filter output is the 10.7 MHz IF signal to the Receiver module (A4).
5-45. A second mixer in the receiver module down converts the 10.7 MHz IF signal to 455 kHz by mixing the input signal with a 10.245 MHz Second Local Oscillator. The Second Local Oscillator is phase locked to the 1O MHz system standard so that its frequency is as accurate as the standard. The phase locked loop for the Second Local Oscillator is split between two modules. A 10.245 MHz SAMPLE signal is compared with the REFERENCE FREQUENCIES from the RF Synthesizer on the Processor 1/0 module (A7). The comparison provides a TRACKING VOLTAGE error signal to the 10.245 MHz oscillator which corrects its frequency to hold it in lock.
5-46. Immediately following the second mixer is the IF filter. The IF filter is selectable between a narrowband (±6 kHz mod acceptance) and a wideband (±100 kHz mod acceptance) bandwidth. The bandwidth is under the control of the processor and is selected by the bandwidth switch on the front panel.
5-15
5-47. The output signal from the IF filter has two possible paths. The path to the Log Amplifier and Detector provides the spectrum analyzer capability. The other path is the linear IF Amplifier for AM, FM, and SSB demodulation. The output level of the Amplifier is detected to give amplitude modulation and to provide the AGC control on the IF amplifier. The IF signal is applied to the FM Demodulator and is sent to the Scope/DVM Control module (A3) for SSB demodulation and for frequency error determination.
5-48. Demodulated audio from the selected demodulator is routed to the Audio Filter by the Select Switch under processor control. The Audio Filter provides post detection filtering for both wide and narrow band modes. The output of the Audio Filter is three signal lines. The Demod Calibration Audio line provides the calibrated audio levels for modulation level determination. A Demod Audio output provides a level adjusted signal to the front panel Demod Out jack. Speaker audio is level adjusted by the front panel volume control and then amplified by the Audio Amplifier on the Receiver module.
5-49. The Audio Amplifier sums the audio from the demodulator with the Alarm audio. The Audio Amplifier provides a 0.5 watt output capability to the system's internal speaker. The Alarm generator is under the control of the system processor.
5-50. SSB demodulation is implemented on the Scope/DVM Control module by' multiplying the 455 kHz IF signal from !he Receiver with a signal from the Beat Frequency Oscillator (BFO). The BFO is controlled from the front panel and typically has a frequency range of 455 ±3 kHz. The BFO signal is switched with the output of the 455 kHz IF Phase Locked Loop (PLL) to the frequency counter for frequency error determination. The455 kHz PLL filters and shapes the IF signal to make it suitable for frequency counting.
5-51. When in the spectrum analyzer mode the linear IF Amplifier is shut down and the Log Amplifier is activated. The output of the Log Amplifier and Detector is a DC voltage that is proportional to the log of the 10.7 MHz IF input level. The log circuit has a dynamic range of approximately 80 dB, covering input levels from -100 dBm to -20 dBm. The SPECTRUM ANALYZER signal from the Log Amplifier is the vertical input to the scope for the spectrum analyzer display.
5-52. Duplex Generator
5-53. Simultaneous generate and monitor functions are available with the use of the Duplex Generator. The frequency spread between generate and monitor frequencies is limited to a range of 0 to 10 MHz and a fixed frequency of 45 MHz. A block diagram of the Duplex Generator function is shown in figure 5-7.
5-54. The Duplex Output signal is generated by mixing the local oscillator signal for the first receive mixer with a signal from the Offset Oscillator. The Offset Oscillator is at the frequency equal to the desired spread between generate and monitor frequencies less the 10.7 MHz IF offset. The monitor function is unaffected by the duplex mode and operates as described under paragraph 5-40.
5-55. Frequency modulation of the duplex output is obtained by modulating the Offset Oscillator frequency via the OFFSET MOD signal line. Control of the Offset Oscillator is directly from the front panel of the system. A OFFSET FREQUENCY output from the oscillator provides an input to the frequency counter for the determination of the duplex frequency.

5-56. Code Synthesizer
5-57. Three simultaneous modulation sources are possible with the internal Code Synthesizer. A private line (PL) or Digital Private Line (DPL) source, a fixed 1 kHz source, and external modulation sources are individually level controllable and sumed together to give the composite modulation audio. The Code Synthesizer provides the modulation source for the system in the generate mode and can be used as an audio frequency source when in the monitor mode. For the IEEE option a provision is made to allow processor control of the modulation levels. A block diagram of the Code Synthesizer is shown in figure 5-8.
5-58. The PL signaling sequence generator is an Audio Synthesizer with an output frequency range from 5 Hz to 10 kHz in 0.1 Hz steps. The frequency is programmed by the processor in response to the operator's request from the keyboard through the CRT display. The Programmable Attenuator following the synthesizer provides 10 dB and 30 dB attenuation levels for the tone remote access sequence.
5-59. DPL Code words are generated by the processor in response to the code entered by the operator. The 23-bit DPL word is stored in the DPL Generator and continuously output when selected. Either PL or DPL signals are switched to the Code Synthesizer Level control on the front panel.
5-60. A 1 kHz reference signal from the RF Synthesizer is bandpass filtered to provide a low distortion 1 kHz sinewave to the front panel 1 kHz Level Control.
5-61. Two sources of external modulation are possible. A standard Motorola microphone interface jack on the front panel and a BNC front panel jack are provided. The microphone input is connected to an IDC circuit for peak limiting. The composite of the two external modulation sources is the signal to the External Level control on the front panel.
5-62. Systems without the IEEE option will have the wipers of the level control pots jumpered to their respective inputs to the summation amp on the Audio Synthesizer module (A6). Those systems with the IEEE option will select on the IEEE Interface module (AB) either the tops of the level controls or their wipers to the Programmable Attenuators for remote or local control respectively. While in the IEEE Control mode the processor controlled Programmable Attenuator on the IEEE module provides the modulation level control. For the local mode the attenuators are programmed for zero attenuation so that the wipers of the level controls set the modulation levels directly.

5-63. The three modulation sources are sumed together on the Audio Synthesizer module after the level controls. The composite modulation signal is then switched to the appropriate modulator and applied to the modulation determination circuitry (MOD CAL AUDIO), the audio amplifier (SPKR AUDIO), and the Modulation Output jack (MOD OUT) on the front panel. The signal to the front panel jack is buffered by a Driver Amplifier to provide a low driving source impedance.
5-64. The AM modulation signal at the output of the Select Switch is sumed with a +5 volt signal. This combination provides a DC level to control the average output power of the wideband amp in the RF Input module, and a superimposed modulation signal to give an AM output. The RF Level control on the front panel for local control or the Programmable Attenuator on the IEEE module provide local or remote RF level control by simultaneously attenuating the DC level and the modulating signal. The resulting signal is the AM MOD & DC REFERENCE signal to the RF Input module.
5-18
5-65. Frequency Counter
5-66. Three possible signal sources are made available to the frequency counter for frequency determination. Two of the inputs are from internal system points for the determinations of the offset frequency (OFFSET), and the monitored carrier error frequency (IF/BFO). The third input is the external input (FREQ CNTR INPUT) on the front panel. A block diagram of the frequency counter function is shown in figure 5-9.

5-67 .· The external input signal is routed to the Front Panel Interface module (A12). A range Attenuator on the Interface module provides variable sensitivity settings according to the vertical range switch setting on the front panel. An Amplifier following the range Attenuator amplifies and limits the signal amplitude for the frequency counter input.
5-68. A Select Switch on the Processor 1/0 module (A7) routes the desired signal to the Frequency Counter circuitry. The signal selected is controlled by the processor and is determined by the operating mode of the system.
5-69. A 16-bit gated accumulator is used to determine the input frequency. Gate times from 1 msec to 10 sec are automatically selected by the processor to give the maximum possible resolution. The gate times are derived from the RF Synthesizer REFERENCE FREQUENCIES and thus are as accurate as the system time base.
5-70. The 16-bit Frequency Counter output is transferred directly to the processor bus through a Peripheral Interface Adapter (PIA). The processor in turn adjusts the data for the gate time used and then processes the information to obtain the required frequency display.
5-71. Digital Voltmeter (DVM)
5-72. The processor through the DVM circuitry has access to voltage information at a large number of points throughout the system. From this information the processor is able to determine and display parameters such as; output power level, modulation level, input power level and the like. In addition an external voltage applied to the DVM input jack on the front panel can oe measured and displayed for external voltage measurements. A block diagram of the DVM function is shown in figure 5-10.

5-73. Switching for the DVM input is contained on the Scope/DVM Control module (A3). One of ten internal measurement points may be selected for measurement. The switching action is controlled by the processor and is performed as required to obtain the information on the CRT. To keep the CRT information current, each of the required measurements are made in sequence at an approximate rate of thirty per second. The net effect is a multiplexing of the voltage information to the processor.
5-74. Two modulation signals (MOD CAL AUDIO and CARRIER+ MOD LVL) and a demodulated signal (DEMOD CAL AUDIO) are made available to the peak detectors. Positive and negative peak determination of the selected signal enables the processor to determine the level of modulation.
5-75. A Lowpass Filter (LPFL) removes the DC component from the CARRIER+ MOD LVL signal so that the generate RF output level can be determined. Refer to paragraph 5-30.

5-76. The RF INPUT POWER and OVERTEMP signal lines from the RF Input module provide the processor inputs for the internal wattmeter. (Paragraph 5-38).

5-77. A signal line from the DC input jack on the rear panel (BATT VOLT) is brought to the processor for battery voltage determination. The voltage is attenuated by a factor of 10 to stay with the 10 volt maximum input to the select switch. The processor uses the battery voltage measurement to warn the operator when the battery is near it's discharged state.
5-78. Sinad determination utilizes the two remaining inputs to the select switch. For a discussion on the sinad function see para 5-96.
5-79. The selected internal measurement signal is then passed through a range attenuator. Signals from the Select Switch have a 0 to +10 volt range while the DVM input has a 1 volt maximum input requirement. The processor automatically determines and sets the correct range on the attenuator so that the input level to the DVM is maintained at less than 1 volt. For levels from the select switch less than 1 volt, the attenuator is ranged to the unity gain position for maximum measurement resolution.
5-80. A select switch following the internal range attenuator gates either the internal measurement points or the external 'input to the DVM circuitry. External DVM inputs are applied through the front panel jack to the Front Panel Interface module (A12). On the Interface module, a processor controlled switch selects between a direct coupled or a capacitively coupled path for DC and AC measurements respectively. A range attenuator follows the AC/DC switch to provide processor controlled autoranging over a four decade range. Input voltages from 1 millivolt to 300 volt can be handled through the DVM Input.
5-81. For DC measurements a lowpass filter {LPFL) removes AC signal components. The filter provides approximately 25 dB rejection at 50 Hz so that accurate DC measurements can be made with superimposed AC line ripple. When the AC measurement mode is selected the LPFL is reprogrammed for less than 0.5 dB rejection at 10 kHz.
5-82. Positive and negative DVM input levels are full-wave rectified by the Absolute Value circuit on the Processor 1/0 module (A7). The outputs of the Absolute Value circuit provide a positive voltage level equal to the magnitude of the input voltage and a SIGN BIT indicating the polarity of the input signal. For AC measurements a lowpass filter is switched into the Absolute Value circuit to filter the rectified AC input for it's average level. The processor then multiplies by 1.11 to obtain the RMS value.
5-83. An analog to digital converter (A/D) converts the magnitude voltage level into a 10-bit digital word. This digital word when combined with the SIGN BIT is a binary representation of the input voltage level. The peripheral interface adapter transfers the information to the processor.
5-84. Oscilloscope
5-85. Three basic functions are provided for by the system oscilloscope. The alphanumeric and modulation displays provide operating mode and control information for the system. The external oscilloscope feature augments the total system as a general purpose test instrument. A block diagram of the oscilloscope function is shown in figure 5-11.
5-86. Drive signals for the CRT are provided by circuits on the Scope Amplifier module (A2). Horizontal and vertical signals are amplified by their respective amplifiers from 0.5 volt/division input levels to the levels required on the deflection plates. AZ-Axis Modulator circuit controls the cathode to grid bias voltage on the CRT to effect intensity control.

5-87. The horizontal amplifier input is selected between external and internal scope functions. External functions, Time base Generator or external horizontal input, are switched to a sumation amp where the HORIZONTAL POSITION signal from the front panel is added. The resulting DC offset positions the display horizontally on the CRT.
5-88. Six decade sweep ranges from 1µ sec to 100 msec per division are provided by the Time base
Generator. Control of the Time base Generator is from the front panel horizontal switch through the processor. 5-89. Front panel external horizontal inputs are applied to the top of the horizontal vernier gain potentiometer. The wiper of the gain potentiometer is the EXTERNAL HORIZONTAL input signal to the
5-22
preamp on the Front Panel Interface module (A12). The preamp provides the required horizontal input sensitivity and buffers the signal to the select switch on the Scope Amplifier module.
5-90. Internal horizontal signals, Sweep Generator and Character Sweep outputs, are selected on the Scope/DVM Control module (A3). The Sweep Generator provides a sawtooth waveform to the RF Synthesizer module for the sweep generator and spectrum analyzer functions. The sweep signal to the CRT horizontal input causes the scope sweep to be synchronous with the synthesizer sweep for the spectrum and swept filter response displays.
5-91. The Horizontal Character Sweep generator output is a sawtooth waveform that provides the horizontal sweep for the raster scan character display.
5-92. One of four possible vertical signal sources are switched to the Vertical Amplifier input by a Select Switch on the Scope/DVM Control module. The 455 kHz IF and SPECTRUM ANALYZER signals from the Receiver Module provide the IF envelope and spectrum analyzer displays respectively. The Vertical Character Sweep generator gives the vertical sweep for the raster scan character display. The remaining input is the path for external vertical or modulation scope vertical inputs from the Front Panel Interface module.
5-93. A vertical preamplifier on the Interface module gives a vertical sensitivity of 10 millivolt per division and provides positioning and vernier gain capability for its input. The amplifier is preceeded by a four decade range attenuator which is controlled from the front panel vertical switch through the processor. The attenuator provides external vertical input sensitivities from 0.01to1.0 volt per division and modulation scope sensitivities from 0.25 to 25 kHz per division.
5-94. A Select Switch ahead of the Attenuator selects between the external vertical input or the modulation scope inputs. The External Vertical input path is further selected between AC and DC coupling before becoming the vertical input jack on the front panel. The modulation scope signal path is switched to orie of three possible sources on the Scope/DVM Control module. Demodulation signals from the Receiver are selected via the DEMOD CAL AUDIO path, and frequency and amplitude modulation signals via the MOD CAL AUD 10 and CARR IER + MOD LVL signal paths respectively. The Audio Synthesizer module provides the MOD CAL AUDIO signal while the RF Input module gives the CARRIER+ MOD LVL signal.
5-95. AZ-Axis Select circuit on the Scope/DVM Control module gates either the CHARACTER GEN signal for character displays or the retrace blanking signal from the Time Base Generator for scope displays to the ZAxis Modulator on the Scope Amplifier module.
5-96. Sinad Meter
5-97. Sinad, which is defined as the ratio of noise plus distortion to signal plus noise plus distortion, is a measurement of the audio quality at a receiver output. Measurement of the Sinad is implemented with a 1 kHz notch filter. For a receiver receiving a 1 kHz tone the audio output is applied to the 1 kHz notch filter. Sinad is then the ratio of the signal power at the output of the notch filter to the signal power at the input of the notch filter. A block diagram of the Sinad Meter is shown in figure 5-12.
5-98. The Sin ad Input from the front panel is AC coupled to the range Attenuator on the Front Panel Interface module (A 12). Processor control on the Attenuator allows a wide range of input levels to be automatically handled. The output of the Attenuator is routed to the 1 kHz Notch Filter on the Scope/DVM Control module (A3). Detectors, comprised of fullwave rectifiers and filters, on the input and output of the notch filter determine the respective power levels. The DC outputs of the detectors are read by processor through the DVM. The processor determies the ratio between the two readings and displays the Sinad.

SECTION 7
LOW VOLTAGE POWER SUPPLY (A1)
7-1. GENERAL. The low voltage power supply (figure 7-1) converts an AC line voltage input or a DC voltage input to the required DC operating voltages. The power supply is composed of four modules, each module containing a printed wiring board. These modules are the relay, control, switcher, and output modules. Protection circuits protect the power supply against short circuits, high internal temperatures, and high and low DC bus voltages.
7-2. INPUT POWER CONTROL. When AC power is applied to the power supply, the output of the AC rectifier and filter circuit provides the DC bus voltage. An AC sense circuit provides a control voltage when AC power is present. This control voltage isolates the DC voltage input from the DC bus and drives the front panel AC indicator.
7-3. The off, standby, or on operating mode of the power supply is selected by the control circuit. When the analyzer is off, the frequency standard and chopper generator are off, and the battery charger is on. When the analyzer is in standby, the chopper generator is off and the frequency standard and battery charger are on. When the analyzer is on, the frequency standard and chopper generator are on and the battery charger is off. Thus, the battery is charged when the analyzer is in the off and standby modes of operation. The frequency standard operates in the standby and on modes of operation.
7-4. The battery charger requires a voltage higher than the nominal DC bus voltage. This increased voltage, 32V, is provided by the AC boost circuit.
7-5. To operate the power supply using a DC voltage input, the AC power input must be removed, disabling the AC sense voltage. When the AC power is removed and the analyzer turned off, no power is present on thf'! DC bus. When the analyzer is switched to the standby mode, the DC relay closes, connecting the DC voltage input to the DC bus and the supply voltage to the frequency standard. When the analyzer is switched on, the chopper generator is enabled and normal operation occurs.
7-6. DC OUTPUT CONTROL. Regulation of the DC output voltages is accomplished by using the +5 volt output as feedback. This feedback voltage is compared to a stable reference voltage (7.9V). The resultant control voltage determines the on time of the pulse width modulator, thus regulating the input voltage to the chopper circuits. The output transformer winding ratios determine the output voltages with respect to the +5-volt feedback.
7-7. The chopper generator provides a 7-volt reference voltage, a 20-kHz squarewave chopper drive signal, and a 20 kHz triangular waveform output for pulse width modulator control. The pulse width control compares the triangular waveform with a control voltage. When the control voltage is equal to the mean DC voltage of the triangular waveform, the pulse width modulator has a 50 percent duty cycle. For control voltages that are above or below the mean DC voltage of the triangular waveform, the duty cycle is proportionately increased or decreased.
7-8. The filtered DC output from the pulse widths modulator is chopped 50 percent through the primary windings of output transformer T2 at a 20 kHz rate. The DC output is alternately switched between each half of the primary winding of T2. Current through the primary winding center top is passed through a current transformer whose output is used for overcurrent protection.
7-1
7-9. PROTECTION CIRCUIT. This power supply is protected from shorted outputs, high internal temperatures, and high or low DC bus voltage. In each case, the protection circuit pulls the control voltage line low, disabling the pulse width modulator and shutting down the power supply outputs.
7-10. Short circuit protection is provided by monitoring the current in the primary winding of the output transformer T2. When an output is shorted, the primary winding current will increase significantly. This causes the overcurrent detector to pull the control voltage line low, disabling the pulse width modulator and shutting down the output. With the output shut down, there is no primary winding current, causing the control voltage line to be released. When the control voltage line is released, the pulse width modulator is again enabled and the power supply outputs are available again. If the short circuit is still present, the shutdown sequence will be repeated. A delay is provided in the overcurrent detector causing the shutdown sequence to cycle at an approximately 0.5 second rate.
7-11. Over temperature protection is provided by a thermal switch. When the temperature of the power supply exceeds the setting of the thermal switch, the switch closes, pulling the control voltage line low, disabling the pulse width modulator and shutting down the power supply outputs. Normal power supply operation will resume when the temperature returns to a safe operating level.
7-12. Protection against high or low DC or AC line inputs is provided by monitoring the DC bus voUage. When the DC bus voltage exceeds 20 volts, or falls below 10 volts, the high/low shutdown circuit pulls the control voltage line low, disabling the pulse width modulator and shutting down the power supply outputs. When the DC bus voltage returns to normal, the power supply will automatically resume normal operation.
7-13. HIGH VOLTAGE CONTROL. The HV BIAS V line and the HV SOURCE V line provide the high voltage power supply A10 with bias voltage and primary power, respectively.
7-14. SWITCHER MODULE A1A1. The switcher module (figure 7-2) contains the pulse width modulator and chopper circuits. The input PWM DRIVE signal, from the control module, switches the chopping circuit on and off. This produces a rectangular wave output which is filtered and applied to transformer choppers A and B. In effect, this action regulates the voltage which is applied to transformer T201 on the output module. The PWM OUT signal is a secondary input to the voltage regulator comparator on the control module.
7-15. Transformer choppers A and Bare driven by CHOPPER DR A and CHOPPER DR B signals from the control module. Output signals XFMR DR A and XFMR DR Bare 180-degrees out-of-phase and XFMR DR A1 and XFMR DR 8 1 are180-degrees out-of-phase. An output, HV SOURCE V, from the chopping circuit is the primary power source for the high voltage power supply.
7-16. OVP (Overvoltage Protection). The OVP zener is connected to the +5V output from the output module and limits the maximum +5 volt level to +6.3 volts.
7-17. OUTPUT MODULE A1A2. The output module (figure 7-3) provides the regulated output voltages and the current sense voltage for the overcu rrent protection circuit. Input power is provided by signals XM FR DR A, A1, B, and 8 1· These signals are 20 kHz squarewaves and drive the primary windings of transformerT201. After full wave rectification and filtering, the nominal output voltages are available as shown in figure 7-3.
7-18. The primary current of transformer T201 is monitored by transformer T202. The voltage developed across T202 is full wave rectified and applied to the current limit circuit on the control module by the CURRENT LIMIT SENSE signal. An increase in the primary current of T201 produces a corresponding increase in the voltage developed across T202. This increase is applied to the current limit circuit and overcurrent protection is initiated.
7-2
7-19. Regulation of the output voltag~ is accomplished by the +5-volt feedback. When the +5-volt output is regulated, the remaining output voltages will be regulated because of the turns ratio of the windings between the outputs. When the +5-volt output is held to one percent regulation, the other outputs will be held to five percent regulation.
7-20. The OVP (Overvoltage Protection) output is applied to a 6.2-volt zener diode mounted on the chopper assembly. This provides overvoltage protection to the +5-volt output.
7-21. CONTROL MODULE A1A3. The control module (figure 7-3) provides pulse width modulation control
and contains the protection circuits. Pulse width modulation control is accomplished by comparing a 7.9V
I
reference voltage to the +5-volt feedback from the output module. The resultant integrated control voltage is applied to the pulse width control. This voltage is compared to the 20 kHz triangle voltage to determine the duty
cycle of the pulse width modulator. The chopper drive outputs are squarewaves and are 180-degrees out-of-
phase with each other.
7-22. When the DC BUS voltage is over 20 or under 10 volts DC, the over/under voltage protection circuit pulls the control voltage signal to the pulsewidth control circuit low. This action shuts down the pulsewidth modulator.
7-23. The soft start circuit slows the rise time of the control signal to the pulsewidth control circuits. When the signal reaches the operating level the soft start circuit is switched out of the control loop.
7-24. The overcurrent detector compares a signal that is proportioned to the current in the current transformer, to a reference. When the current is too high, the control signal is pulled low, shutting down the output module. After a delay, the output module operates again, if the malfunction causing the overcurrent is still present, the module will shutdown again. This sequence will cycle at a 0.5 second rate until the malfunction is corrected.
7-25. When the internal temperature of the power supply rises above 85°C, the overtemp shutdown circuit causes the control signal to go low, shutting down the pulsewidth control circuit. The control logic functions are shown in table 7-1.

7-24. RELAY MODULE A1A4. The relay module (figure 7-5) is mounted on one end plate of the power supply. Primary power is applied to.the module through a line transformer or the DC input. When an AC input is used, the RELAY ENABLE line is high, the relay is open, and the power supply operates from the AC input. The MAIN AC and MAIN AC lines receive a 13.5-volt AC rms input from the line transformer. After full wave rectification, the DC power is routed throughout the power supply on the DC bus. Filtering of the DC power is done on the switcher module. 7-25. When the DC input is used, the RELAY ENABLE line is low, the relay is closed, and the power supply operates from the de input. The battery charge voltage is boosted to 32 volts using the AC bus voltage to bias an AC boost winding center tap.

SECTION 8
SCOPE AMPLIFIER (A2)
8-1. General. The Scope Amplifier module contains the horizontal and vertical deflection amps, the horizontal timebase generator, focus and intensity control circuitry, and miscellaneous CRT bias adjustments. A block diagram of the Scope Amplifier module is shown in figure 8-1 with its schematic shown in figure 8-2.
8-2. Deflection Amplifiers. The vertical and horizontal deflection amplifiers are identical. The input signal is initially amplified and split into two signals 180° out of phase. Each of the two signals is then further amplified to become the CRT deflection plate signals. The amplifiers provide up to 200 volts peak-peak signal capability with a 1 MHz frequency bandwidth.
8-3. Horizontal Timebase Generator. The horizontal timebase generator provides calibrated sweep rates
over a six decade range from 1µ sec to 100 msec per division. Sweep rate selection is from the processor via
the SCOPE SWP CONT 0-7 signal lines. Veriner control over the sweep rate is via the SWP VERN VOLT input from the front panel. Sweep triggering is either the auto or normal mode as selected by the AUTO/NOR TRIG SEL line from the front panel. In the auto mode if the SYNC PRESENT input is high indicating no sync, the scope sweep is self triggered after a hold off time. If there is a sync present, the sweep will wait for a pulse on the TRIG PULSE line to start the sweep after the hold off time. For the normal trigger mode the sweep will always wait for a TRIG PULSE input.
8-4. A sweep cycle consists of two parts, the sweep and the hold off. During the sweep the CRT is unblanked via the SWP BLANKING line and the horizontal trace is made. At the end of the sweep the CRT is blanked and the hold off time begins. During the hold off time, which is equal to the sweep time, the sweep generator and trigger circuits are reset in preparation for the next sweep.
8-5. Horizontal Switching. The input to the horizontal deflection amp is selected between two sources. The INT HORIZ IN signal line provides the horizontal character sweep and the horizontal spectrum analyzer sweep. The other source is the scope mode signal path from the horizontal positioning suming amp. The scope mode signal is either the output of the Horizontal Timebase Generator or the EXT HORIZ INPUT from the front panel. Selection between internal horizontal and scope mode horizontal inputs is via the SCOPE MODE EN line from the processor. Selection between the two scope mode signals is via the EXT HORIZ EN line.
8-6. Intensity Control. A crossover network is used to provide CRT Z-axis modulation from DC to 1 MHz. The INTEN LVL signal from the front panel control is gated with the SCOPE Z-AXIS signal by the Intensity Level Gate. The gated signal is sumed with the HV REF and INTEN SMPL VOLT signals to provide the INTEN TV signal. The INTEN TV (Intensity Tracking Voltage) is the low frequency control path which drives the intensity optoisolator in the High Voltage Supply.
8-7. The high frequency modulation path is via the Z-Axis Modulator circuit. line. line. The resulting CRT ZAXIS signal is capacitively coupled to the CRT grid.
8-8. Focus Control. The FOCUS TV (Focus Tracking Voltage) signal is obtained by comparing the FOCUS LEVEL control line to the FOCUS SAMPLE VOLT signal. The tracking voltage signal drives an optoisolator circuit in the High Voltage Supply which controls the CRT focus voltage.
8-9. Astigmatism, Geometry, and Trace Rotation. These three CRT alignment controls are obtained from the respective wipers of three potentiometers. Each potentiometer is connected between supply voltages equal to the adjustment range required.

Figure 8-3. Vertical/Horizontal Scope Amplifier Module A2 (RTC-40078) Parts Location Diagram
SECTION 9
SCOPE/DVM CONTROL MODULE (A3)
9-1. General. A primary function of the Scope/DVM Control Module is to route the required measurement and viewing signals to the DVM and scope circuitry. A large portion of the displayed data is determined by the DVM measurements on internal signal points. Thus for a rapid update of several data displays it is necessary to time division multiplex several measurement points to the DVM. The DVM control circuitry and the system processor provide this function.
9-2. The scope control circuitry allows the system to display data information, internal modulation or demodulated signals, and external scope inputs as selected by the user. Provisions are also made for external horizontal inputs and a horizontal sweep that is coherent with the sweep generator for spectrum analyzer and filter alignment displays.
9-3. The control module also contains circuitry for single sideband demodulation and a IF phase locked loop for filtering and waveshaping the IF signal for frequency counting. A block diagram of the Scope/DVM Control module is shown in figure 9-1 with a schematic shown in figure 9-2.
9-4. Scope Vertical Control. The input to the scope vertical amplifier is switched between four different sources; the range switch (VERT FROM RNG SW), the vertical character sweep, the spectrum analyzer (SPECT ANA VERT), or the 455 kHz IF. Range switch inputs are from eitherthe scope vertical input jack on the front panel or the internal modulation signals as selected by the modulation display control on this module. The vertical character sweep is a sawtooth waveform generated by the Vertical Character Sweep Generator and synced by the VERT CHAR SYNC signal from the character generator. The detected and amplified output of the receiver logarithimic IF is the vertical input forthe spectrum analyzer. The remaining signal source is the second IF signal from the receiver for IF envelope observation.
9-5. For the spectrum analyzer and the scope sweep displays the Dual Display Control and Character Sweep
Counter circuitry allow a single row of characters at the top of the CRT. This function is implemented with the
I
Vertical Sweep Control by alternating the spectrum analyzer or the range switch signal with the vertical character sweep signal.
9-6. The dual display sequence of events starts with the Synthesizer Sweep Generator which is common to both display modes. When the synthesizer sweep is near its peak (scope horizontal sweep is at the edge of the screen) the Dual Display Control activates the CHAR GEN RST line and switches the scope vertical and horizontal inputs to their character generator sweeps. When the first character line has been traced, a transition on the LINE 1 input from the character generator resets the character generator sweeps and the character generator, increments the Character Sweep Counter, and thus causes line 1 to be traced again. This process repeats until four traces.as counted by the Character Sweep Counter, have been completed. At that point the counter resets the scope inputs back to the spectrum analyzer or range switch input. During the character display time the synthesizer sweep generator is reset and held until a transition on the SY NTH SWP SYNC line restarts the sweep. The timing of the process allows for the four character traces to be completed before the sweep sync occurs.
9-7. SSB Detection. Single Sideband (SSB) modulation is recovered by multiplying the 455 KHz IF signal with a 455 KHz beat frequency oscillat,or (BFO) signal. The BFO is controlled directly from the front panel and is adjustable over a 6 KHz frequency range. SSB AUDIO from the multiplier is routed to the receiver for post
9-1
detection filtering. A sample of the BFO signal is made available to the frequency counter on the IF/BFO FREQ line for sideband frequency error determination.
9-8. 455 KHz PLL. For monitor frequency error determination a 455 KHz Phase Locked Loop (PLL) is used to filter and to shape the IF signal. The cleaned up signal is switched with the BFO signal to the frequency counter.
9-9. Scope Horizontal Control. Switching for the scope horizontal input is divided between two modules. The time base generator and the external horizontal input are selected on the scope amplifier module. The. Horizontal Character Sweep Generator and the Synthesizer Sweep Generator signals are selected on the Control Module to the INT SCOPE HORIZ signal line.
9-10. For the dual display modes (characters and synthesizer sweep) the Horizontal Switch Control switches the horizontal input between the synthesizer sweep and the character sweep. This switching occurs simultaneously with that occurring in the scope vertical control as described in paragraph 9-6. The Horizontal Switch Control also provides the SCOPE MODE EN line to the scope avplifier to enable the scope mode horizontal inputs.
9-11. Synthesizer Sweep Control. The sweep signal generated by the Synthesizer Sweep Generator is controlled in amplitude and in range across the front panel sweep width control. Attenuations of 1.0 or 0.1 are provided by the Sweep Width Select circuitry to the sweep signal at the DISPERSION SWP signal line to the top of the width control. The bottom side of the width control is returned to the Sweep Width Select circuitry via the DISPERSION SWP RTN line. A 10 to 1 resistor change is made in the return line simultaneously with the attenuator change to give sweep ranges of 1-10 MHz and 0.01-1 MHz.
9-12. Scope Z-Axis Control. The SCOPE Z-AXIS signal has three possible sources as selected by the Z-Axis Control circuit. For character displays the Z-Axis signal is the CHAR GEN Z-AXIS from the character generator. The SWP BLANKING signal from the horizontal timebase generator is switched to the scope Z-Axis for the scope modes. For the remaining modes, spectrum analyzer and scope sweep, a logic zero level is gated to the Z-Axis input.
9-13. Modulation Display Control. Internal modulation or demodulated signals are displayed on the scope by switching the desired signal source to the input ranging switch and then switching the ranging switch output to the scope vertical input. One of two modulation sources or a demodulation output can be switched to the INT SCOPE TO RNG SW signal line for display on the CRT. Each of the signals are gain adjusted prior to the selection switch for scope calibration.
9-14. The DEMOD CAL AUDIO signal from the receiver is either AM, FM, or SSB as determined by the operating mode. The peak signal level on this line is calibrated to 10 kHz/volt for FM and 10%/volt for AM. SSB signals are not calibrated.
9-15. For AM the CARRIER+ MOD LVL input from the generator output detector provides a direct display of the modulation. This input is a DC level representative of the average output level plus an AC signal representative of the amplitude modulation on the output. For the scope modulation display the DC level is blocked so that only the AC component is observed. This input is uncalibrated for absolute AC levels, but the processor by determining the peak AC and average DC levels can determine the modulation depth.
9-16. For FM the MOD CAL AUDIO input from the audio synthesizer is calibrated to 5 kHz/volt for narrow band and to 20 kHz/volt for wide band. Correspondingly the display calibrating attenuator has two gain ranges to maintain the same display ~~libration for both narrow and wide band.
9-2
9-17. Peak Detector. Each of the modulation and demodulation inputs can be selected to the peak
detecting circuitry for the determination of% AM or kHz deviation. The peak detector circuitry provides DC
outputs equal to the negative and positive peak values of the input signal relative to the average DC level of the
signal. These levels are then digitized by the DVM and input to the processor where the modulation level is
I
determined.
9-18. DVM Control. Any one of ten internal or one external measurement point may be switched to the DVM
for level digitization. Switching is controlled by the processor so that measurements are made to provide
current display data. In general several measurement points must be input to obtain all the displayed data.
Therefore the processor continuously cycles the switch through the required inputs stopping at each one long
enough to digitize and input its level.
9-19. The Internal DVM Select switch is followed by a range attenuator. As the processor cycles through the inputs it sets the range attenuator according to the last cycle reading made at that input. Thus each internal input is auto ranged over two decades to give three digit accuracy up to a maximum input of 10 volts. The internal DVM inputs and their function are listed in table 9-1.

9-20. External DVM inputs to the front panel jack are ranged by the processor over a four decade range before being routed to the DVM switch. At the Internal/External DVM Select switch the external DVM FROM ANG SW signal or the internal signal from the x0.1 Attenuator is selected to the DVM to A/D signal line for digitization.
9-3
9-21. SINAD Detection. The SINAD of a signal on the DVM FROM RNG SW line is determined by taking the ratio of the input to the output signal power on the 1 kHz Notch Filter. Signal power is determined by Rectifier and Filter circuits whose outputs are DC levels proportional to the input signal levels. The DC levels, SINAD IN and SINAD OUT are digitized and input to the processor where the SINAD is calculated. 9-22. Module Control. Processor control of the Scope/DVM Control module is via the AF ADD BUS 0-3, the AF DATA BUS 0-3, and the AF BUS EN 1 signal lines. The four address bits are decoded by the Address Decode to determine which Control Latch the fours bits of data will be latched. The latching process is synchronized by the enable line. Control latches in addition to those necessary for controlling the module provide control for the Scope Amplifier module and part of the RF Input module.

SECTION 10
RECEl'(ER (A4)
10-1. General. The Receiver down converts the 10.7 MHz first IF signal to 455 kHz. Following the down conversion a linear or a logarithimic IF amplifier provide the gain prior to AM and FM detectors or the spectrum analyzer detector respectively. Post detection filtering provides the wide or narrow band responses for the audio outputs. The audio amplifier for the speaker and the alarm generator are also contained on this module. A block diagram of the Receiver is shown in figure 10-1 and its schematic in figure 10-2.
10-2. Down Converter. The 10.7 MHz IF signal is converted to 455 kHz by mixing with a 10.245 MHz local oscillator. The local oscillator is phase locked to the system 10 MHz frequency standard. A sample of the 10.245 MHz VCO signal is output to the Processor 1/0 module. There the VCO signal is mixed with 10 MHz, the difference is divided by 49, and the result compared with a 5 kHz reference obtained from the 10 MHz. Any frequency difference causes a correction to be made to the VCO frequency via the 10.245 MHz VCO TV line through the Loop Filter.
1~3. The IF filter following the mixer provides the selectivity for the system. Two bandwidths, ±100 kHz wideband and±13 kHz narrowband, are processor selectable to correspond'the front panel bandwidth control.
10-4. Linear IF Amplifier and Deteetors. The linear IF Amplifier amplifies the 455 kHz signal to the AM and FM detectors. The DC signal from the AM detector is fed to the AGC Amplifier and Squelch Detection circuitry. There it is compared to the AGC reference with the resulting AGC signal controlling the gain of the IF Amplifier. For signal present indication and squelcti operation the SQUELCH LVL from the front panel is compared to the AGC voltage. When the AGC voltage fall below the squelch level, indicating a strong signal, the SIG PRESENT line is activated. With the SIG PRESENT active the audio is allowed through the select switch and the signal present light on the front panel is illuminated. To warn the operator when the IF input level is beyond the linear range of the IF amplifier, the AGC voltage is also compared to a fixed IF overload level. When this level is exceeded, the IF OVLD line is activated causing the processor to flash the warning on the CRT display.
10-5. The AC component from the AM detector is buffered by the Audio Buffer and then passed to the Audio Select switch. The lower 3 dB corner on the AM audio response is approximately 100 Hz.
10-6. Frequency modulation is recovered by a dual bandwidth phase locked loop discriminator. The bandwidth, wide or narrow, is selected coincident with the IF Filter bandwidth. Audio from the discriminator is applied to the Audio Select switch.
10-7. A 455 kHz Buffer amplifier provides an interface between the IF Amplifier output and the IF processing circuit.a on the Scope/DVM Control module.
10-8. Audio Switching and Filtering. The output of the AM or FM detector or the SSB AUDIO signal from the Scope/DVM Control module can be selected as the demodulated audio output. Selection is made by the processor depending on the operating mode and the presence of the active state on the SIG PRESENT line. If the SIG PRESENT line is not active, the Audio Select switch is opened squelching the audio signal.
10-9. The Audio FUter provides either wide or narrow band filtering on the recovered audio. For wideband a 0.5 dB bandwidth of 100 kHz is provided.while narrowband has a 0.5 dB bandwidth of 3 kHz. The output of the filter is separateiy buffered to three signal lines. The DEMOD CAL AUD signal is used on the Scope/DVM
1{}-1
Control module for modulation determination, the DEMOD OUT signal goes to the front panel jack, and the VOL CNTL AUD provides the drive to the speaker audio amplifier. 10-10. Logarithmic Amplifier and Detector. For the spectrum analyzer function the logarithmic IF amplifier processes the input signal level over an 80 dB range. The Amplifier is composed of four 20 dB sections summed together. Amplitude detection at the output of the amplifier provides the SPECT ANA VERT signal to the Scope/DVM Control module. 10-11. Alarm Generator and Audio Amplifier. An astable multivibrator operating at 1.2 kHz is the Alarm Generator. The Alarm signal is controlled by the processor and is summed with the VOL CNTL AUD RTN signal at the input of the Audio Amplifier. The SPKR AUD output of the amplifier has 0.5 watt capability and is connected directly to the system speaker. 10-12. Module Control. Address decoding for the two control latches on this module is performed on the Synthesizer module. The two decoded lines, RF LCH ADD 13 and RF LCH ADD 14, determine which Control Latch the four bit data bus, RF DATA BUS 0-3, will be stored.

SECTION 11
RF SYNTHESIZER (AS)
11-1. General. The RF Synthesizer provides an RF signal source for the frequency range from 10 kHz to 1 GHz in 100 Hz steps. The output frequency is programmed by the processor through the RF control bus and is phase locked to the 10 MHz frequency standard. A reference divider in the module produces outputs of 500 kHz, 50 kHz, 5 kHz, 1 kHz, 100 Hz, and 50 Hz (SYNTH SWP SYNC) each having the same accuracy as the frequency standard. A block diagram of the RF Synthesizer is shown in figure 11-1 and its schematic is shown in figure 11·3.
11-2. Frequency Synthesis Scheme. Four phase locked loops are used to generate the output frequency; a 60.5 MHz loop, a 310-440 MHz loop, the 500 MHz-1000 MHz loop, and the 550 MHz loop. Two of these loops contain programmable dividers, controlfed by the microprocessor for varying the frequency. The 310-440 MHz loop is controlled by the four most significant digits of the required frequency and operates in discrete 50 kHz increments. The60.5 MHz loop is controlled by the three least significant digits of the required frequency and operates in discrete 50 Hz increments.
11-3. The output is derived from three sources, covering the ranges of 10 kHz to 250 MHz, 250 MHz to 500
MHz, and 500 MHz to 1000 MHz. In the first range, 10 kHz to 250 MHz, the output is derived by mixing the fixed 550 MHz signal with 500-1000 MHz signaJ programmed for frequencies from 55Cl.01 MHz to 800 MHz. For the second range, 250 to 500 MHz, the output is a divide by two of the 500-1000 MHz signal. The finat range is the 500-1000 MHz signal directly. The appropriate ~Y source is switched to the SYNTK-RF o~ the
Output Select switch.
11-4. A basic flow diagram for programming the RF Synthesizer is shown in figure 11-2. This diagram includes generate and monitor considerations, wideband amplifier control, and modulation control.
11-5. 31CM40 MHz PMse Locked Loop. A single 310-440 MHz VCO is phase locked to the 100 kHz
reference input using a straight forward loop. The VCO output is divided down to 50 kHz using a programmable two modulus prescaler and divider. Programming of the divider is controlled by the processor to give output frequencies from 310 to 440 MHz in 50 kHz steps.
11-6. I0.5 llHz Phae Locked Loop. The 60.5 MHz loop is programmable over a ±100 kHz range in 50 Hz incftlftl8nts. The 60.5 MHz VCO output is mixed with a 50 MHz signal from the 550 MHz loop. A programmable diwfder following the mixer divides the 10.5MHz±100 kHz signal down to the 50 Hz reference frequency. A
corr;pr rl1:on &wJtween the divider output and the referenc:eaignal by the Phase/Frequency detector results in an
..,,, veltage to the vco which maintains the phase lock.
11-7. 550 MHz Plme Locked Loop. A fixed frequ&AGy of 550 MHz is obtained by dividing the 550 MHz VCO
by 55 to obtain 10 MHz. The 10 MHz from the divideri$compared with the 10 MHz frequency standard in the Phase/Frequency Detector. The resulting error signal is filtered and used to correct the 550 MHz VCO to maintain it in lock.
11-8. A Voltage Controlled Attenuator (VCA) follows the 550 MHz output to level the generator output for frequencies below 1 MHz. The leveling loop in the RF Input module provides the ALC VOLT control signal to maintain the required output level at the front panel RF jack. See paragraph 5-31 for a further description of output leveling.
11-1
11-9. 500-1000 MHz Phase Locked Loop. The 500-1000 MHz output is locked to either the sum or the difference of the 310-440 MHz and 60.5 MHz loop output frequencies. In the locked condition, mixing the divide by two output of the 500-1000 MHz VCO's with the 310-440 MHz signal gives a difference frequency equal to the 60.5 MHz output. There are two frequencies at the divide by two output, the 310-440 MHz frequency plus or minus the 60.5 frequency, which will mix down to the correct frequency. However, the sense of the loop is inverted for one compared to the other. Thus the phase switch following the Phase/Frequency Detector determines at which frequency the loop will lock. 11-10. Modulation Control. Modulation of the tuning voltage for the 60.5 MHz VCO provides the frequency modulation of the RF output. Since the modulation sensitivity changes by a factor of two when the 250-500 MHz source is selected, the modulation control provides programmable gain control to maintain constant sensitivity at the FM MOD and SWEEP inputs. Additionally, the wideband modulation mode requires a gain of four beyond that for the narrowband mode. Thus under the control of the processor the Modulation Control selects between the SWEEP and FM MOD inputs, provides gains of 1, 2, 4, and 8 for the FM MOD input and gains of 1 and 2 for the SWEEP input. Input modulation sensitivites are 5 kHz/volt and 20 kHz/volt for narrow and wideband FM input and 2 MHz/volt for the sweep input. 11-11. Module Control. Control information is latched in four bit control latches whicl:l are loaded by the processor through the RF control bus. The four bit RF ADD BUS 0-3 is decoded by the Address Decoder to determine which Control Latch the four bit RF DATA BUS 0-3 is to be stored. Synchronization of the data transfer is the function of the RF BUS EN line. Two decoded address outputs, RF LATCH 13 and 14, select latches on the receiver module for receiver control. One control latch output, LO/HI BAND SEL, goes to the RF Input module to control the frequency range of the output amplifer.

SECTION 12
AUDIO SYNTHESIZER (AS)
12-1. General. Generation, processing, and control of modulation audio is the function of the Audio Synthesizer module. Three modulation signals, private line, digital private line, and a fixed 1 kHz, are generated on the board. Processing for external microphone and BNC jack audio inputs as well as sumation of all modulation sources to form a composite source is provided. Switching of the composite source to the appropriate modulator completes the function of the Audio Synthesizer. A block diagram of the Audio Synthesizer is shown in figure 12-1 with its schematic in figure 12-2.
12-2. Private Line Generator. Private line tones from 10 Hz to 10 kHz in 0.1 Hz increments are synthesized using a phase accumulative technique. Consider the 360 degrees in a cycle to be divided into 220 pieces. A 20 bit digital accumulator incrementing at some fixed rate could then at any instant represent a fixed point in the 360 cycle. That is, if the accumulator was half full it would represent the 180° point and if totally full would represent the 360° point.
12-3. The number of times per second that the accumulator goes through its complete cycle determines 1he output frequency. If the increment rate is fixed, the time required to accumulate 220 bits can be changed by changing the number of bits added at each increment time.
12-4. The PL synthesizer increments at a 104 857.6 Hz rate so that if only one bit were added each time, the time to complete one cycle would be 10 seconds. Processor loaded control latches determine the number of bits to be added at each increment time and thus the final output frequency. A 20 Bit Adder adds the control word to the current word in the 20 bit accumulator Latch. At the next increment time the Adder output is latched and becomes the next .input to the Adder.
12-5. Conversion of the linear digital output of the 20-Bit Latch accumulator into a sinusoidal digital output is the function of the Decode ROM. A Digital to Analog (D/A} converter following the ROM converts the sinusoidal information into a quantized sinewave having a period equal to the cycle time of the 20-Bit Latch accumulator.
12-6. A bandpass filter with a 10 Hz to 10 kHz passband filters the quantized waveform to a sinewave having less than 1% distortion. The level of the sinewave is processor controllable by a programmable attenuator having 0, 10, 20, and 30 dB settings. The output of the PL generator is switched with the output of the DPL generator to give the INT MOD signal.
12-7. DPL Generator. The 23 bit Digital Private Line (DPL} word is generated by the processor from the 3digit code. The 23-bit word is then transferred to a serial shift register and clocked out at a 133 Hz rate. Connecting the output of the shift register back to its input causes the 23-bit word to be continuously repeated.
12-8. A 133 Hz tone from the PL generator is the DPL clock input. For the DPL output mode the tone is gated to the clock input of the shift register by the Shift Register Control circuit. During the load mode the Shift Register Control gates a control latch to the shift register input. Twenty three data bits and clock pulses are then provided by the processor to load the DPL word. At the completion of the load mode, the Shift Register Control switches back to the output mode to cause the DPL word to be cycled through the shift register at the 133 Hz rate.
12-1
12-9. A bandpass filter following the shift register output removes the higher frequency components of the digital signal. The filtered DPL signal is then applied to the select switch. For the DPL off code (133 Hz tone). the processor switches the INT MOD line to the PL output so that a 133 Hz sinewave is output. 12-10. 1 kHz Tone. A filtered 1 kHz square wave provides the fixed 1 kHz modulation source. The SYNTH 1 kHz signal from the RF Synthesizer is filtered to less than 1% distortion by a bandpass filter. The filter output is the 1 kHz signal source. 12-11. External Modulation. A microphone and a front panel jack are the external modulation inputs. An lnstaneous Deviation Control (IDC) circuit amplifies and limits the microphone signal (MIC IN) before sumation with the signal (EXT MOD IN) from the front panel jack. The sumation signal is the EXT MOD source. 12-12. Modulation Control. Level control of the three modulation sources is by either the front R.anel controls or the IEEE interface module. The level adjusted sources are then returned to the Audio Synthesizer module where they are summed together to form the composite modulation audio. The composite signal is then routed to the Scope/DVM Control module (MOD CAL AUDIO) for modulation determination, to a buffer amp which drives the front panel modulation output (MOD TO FP), and to a Modulation Select Switch which routes the signal to the desired modulator. 12-13. Modulation audio is switched to the speaker (VOL CNTL AUDIO) for any generate mode, to the DSBSC modulator (DSBSC MOD) for sideband modulation, to the RF Synthesizer for frequency modulation (FM MOD), to the offset oscillator for frequency modulation of the duplex output (OFFSET MOD), and to the RF output leveling loop for amplitude modulation. The signal for amplitude modulation is summed with a 5 VDC level and then routed to the variable RF level control on the front panel (5 VDC +AM MOD). At the RF level control the signal is attenuated according to the level setting to give the· DC plus AM reference signal for the output leveling loop. 12-14. Module Control. Processor control of the Audio Synthesizer is via the AF control bus. The four bit address bus (AF ADD BUS 0-3) is decoded by the Address Decoder to determine which control latch is to be accessed. Control data is transferred to the accessed latch on the four bit data bus (AF DATA BUS 0-3). Synchronization of the data transfere is the function of the AF BUS EN1 signal line.

SECTION 13
PROCESSOR 1/0 MODULE (A7)
13-1. General. Frequency Counter and DVM functions with their processor interface as well as the processor interface for the two system control buses are contained on this module. Additionally, circuitry to complete the 10.245 MHz phase locked loop, and to zero beat the incoming carrier are also on this board. A block diagram of th.e processor 1/0 module is shown in figure 13-1 with its schematic shown in figure 13-2.
13-2. 10.245 MHz Phase Locked Loop. Only part of the circuitry for the second local oscillator loop is contained on this module. The 10.245 MHz VCO and the loop filter are on the received module. A sample of the 10.245 MHz second local oscillator is mixed with the SYNTH 10 MHz signal. A divide by fourty nine following the mixer divides the 245 kHz signal from the mixer to 5 kHz. A phase comparison between the 5 kHz from the divider and the SYNTH 5 kHz signal results in the 10.245 MHz VCO TV signal. The VCO TV signal is an error signal which is filtered by the loop filter on the receiver to correct the VCO frequency and maintain phase lock.
13-3. System Control Bus Interface. Interface between the processor buses and the system is through Peripheral Interface Adapters (PIA). The PIA is a single integrated circuit that provides 18 input/output latches which may either be read from or written into by the processor. Two additional inputs on the PIA provide for processor interrupt capability. The two system control buses utilize a single PIA
13-4. Each system control bus consists of eight lines split into four data lines and four address lines. The address lines define the particular latch into which the data is to be stored, or the buffer from which data is to be obtained. One additional address line, the bus enable line, is required to enable the address decoding circuitry. Thus each control bus can have as many latches at one address as there are bus enable lines. The system utilizes one RF bus enable and two AF bus enables fora total control buscapabilityof 192 bits. The second bus enable for the AF control bus is on the processor card.
13-5. For internal timing on tone sequences, the processor is interrupted every 10 msec. When interrupted by the timing input the processor stops it current process, acknowledges the interrupt, increments its time counter and then combines as normal. The timing interrupt is the SYNTH 100 Hz input to the Bus PIA.
13-6. DVM. Inputs on the DVM to A/D signal line are digitized into a 10-bit digital word plus a sign bit and then input to the processor through the DVM PIA. An Absolute Value circuit converts the ±1 volt bipolar input signal to a 0-1 volt unipolar positive level with a separate digital output to indicate the sign of the input. An Analog to Digital Converter (A/D) converts the unipolar input into a 10-bit word under processor command. A pulse on the START line from the processor starts the AID. When conversion is complete the AID signals the processor on the END line. The processor in turn enables the output drivers on the AID, sets the OVM/CNTR Buffer to the DVM mode, and inputs the 10bit word plus the signal bit.
13-7. For AC measurements a filter is switched on in the Absolute Value circuit so that its output is a DC level proportional to the average value of the input sinewave. Conversion to RMS is made in the processor by multiplying the average level by 1.11 to obtain the RMS level.
13-8. Frequency Counter. Three possible signal sources are available to the frequency counter for frequency determination. For external inputs the EXT FREQ CTR line from the Front Panel Interface module provides the input. Determination of the duplex frequency is accomplished by measuring the frequency of the offset oscillator on the OFFSET FREQ line. Monitor frequency error is determined from the IF/BFO FREQ line by comparing that frequency to 455 kHz. The desired signal is selected to the counter control by the Select Switch under processor control.
13-1
13-9. The Counter Control circuitry responds to a START pulse from the processor to gate the output of the Select Switch to the Accumulator for a time period determined by the Gate Time Generator. When the gate time has ended, or if the accumulator overflows, the Counter Control signals the processor on the END line that the count is complete. The processor in turn disables the AID output drivers, switches the DVM/CNTR Buffer to the counter mode, and inputs the 16-bit accumulator information. 13-10. Gate times from 0.001 sec to 10 sec are generated by the Gate Time Generator. The SYNTH 1 kHz signal is the reference input for the generator. Selection of the gate time is by processor control to give a five digit or 0.1 Hz resolution frequency display. 13-11. Zero Beat. A zero beat with the incoming carrier is obtained by successively mixing the 455 kHz IF/BFO FREQ with 500 kHz, 50 kHz, and 5 kHz. The beat signal that results from the mixing drives the ground return circuit for the signal presence indicator. 13-12. Module Control. Control of this module is from the processor on the AF control bus. A four bit address (AF ADRS BUS 0-3) is decoded by the Address Decode circuitry to determine which Control Latch the control data is to be stored. The four data bits (AF DATA BUS 0-3) are then stored into the selected ControlLatch by a pulse on the AF BUS EN 2 signal line.

SECTION 14 IEEE INTERFACE MODULE (AS)
14-1. General. Remote control of the system is possible using a IEEE-488 bus and the IEEE Interface Module. The Interface Module provides the interface for the 488 bus and provides for processor control of most of the functions normally controlled from the front panel. A block diagram of the IEEE Interface Module is shown in figure 14-1 with its schematic shown in figure 14-2. See section 22 for information on the use of the IEEE Bus for system control. 14-2. IEEE Bus Interface. Bus buffering and interface protocol as defined by the IEEE-488 specification is provided for by the IEEE Bus Interface circuit. The system processor accesses the interface directly through its address, data, and control buses for reading from or writing to the IEEE bus. 14-3. RF Level Control. The RF Level Control circuitry selects between the 5 VDC + AM MOD or the AM MOD+ DC REF (I) input for remote or local control respectively. For remote control the 5 VDC +AM MOD input is electronically attenuated to provide the requested RF output level. For local control the attenuator is programmed for unity gain so that the AM MOD+ DC REF (I) signal from the front panel RF level potentiometer controls the RF output level. 14-4. For the IEEE control option, a electronically programmable RF step attenuator is installed in the system. Control of the attenuator is then from the processor through the Address Decode and Control Latch circuitry on the Interface Module.
14-5. Modulation Control. Each of the three modulation sources are individually controllable by the IEEE Bus Interface module. For remote control the respective modulation input (INT MOD (I), EXT MOD (I), and 1 kHz SINE) is switched to a programmable attenuator. The system processor selects the level of attenuation necessary to provide the requested level of modulation. For local control the attenuators are programmed for unity gain and the respective modulation signal from the front panel level control (INT MOD RTN (I), EXT MOD RTN (I), and 1 kHz SINE RTN (I)) is selected to the attenuator to provide modulation level control. 14-6. Address Decode and Control Latches. The system processor has direct control over the programmable attenuators on the module with the Address Decode and Control Latch circuitry. Control data on the data bus (D0-07) is latched at the Control Latch indicated by the address bus (AO-A15).

SECTION 15
PROCESSOR MODULE (A9)
15-1. GENERAL. The processor module proviaes primary control and data manipulations for the system. This module contains a processor and buffer, a program memory (ROM), a nonvolative memory (NVM), a random access memory (RAM), a peripheral interface adapter (PIA}, a timing generator, and a character generator. Input and output information is via the peripheral interface adapter and the address, data, and control buses. A block diagram and a schematic diagram of the module is shown in figure 15-1 and figure 15-2, respectively.
15.2 PROCESSOR AND BUFFER. The processor is a Motorola microprocessor MC6802P, operating at a 1 MHz clock rate. This microprocessor controls the processor module via the three signal buses. The address bus provides access to the selected device for data transfers (read/write) from the data bus. Synchronization of the data transfer and specialized processor functions are provided through the control bus.
15-3. PROGRAM MEMORY (ROM). The series of commands (program instructions) that direct microprocessor action are contained in the ROM (Read Only Memory). This ROM is comprised ofthree4096x 8-bit read only memories. An additional 4096 x 8-bit read only memory is provided with the IEEE option.
15-4. NONVOLATILE MEMORY (NVM). The nonvolatile memory provides storage for 84 eight-bit words. Data that is to be held during power off is held in the NVM. When the power is turned on, the microprocessor reads the NVM contents to obtain its start up mode, the RF and tone memory presets, and the remainder of the preset data. If the operator changes a preset, the microprocessor changes the data in the NVM so that the new preset will be remembered.
15-5. RANDOM ACCESS MEMORY (RAM). The random access memory provides temporary storage for both the processor and the CRT alphanumeric display. The RAM has provision to store 1024 eight-bit words, of which 512 are used for the CRT display data. Data is written in a read out of the RAM by the microprocessor.
15-6. PERIPHERAL INTERFACE ADAPTER (PIA). The peripheral interface adapter provides input and output latches for external data from/to the processor module. There are nine inputs from the keyboard, four column inputs (KYBD COL 0-3), and five row inputs (KYBD ROW 0-4). A single input (IEEE OPT DET) signals the processor that the IEEE option is installed. The AF BUS EN 1 output signal synchronizes the transfer of data on the system AF control bus.
15-7. TIMING GENERATOR. The timing generator provides the timing signals for the character generator. All of the timing signals are synchronized to the 1 MHz master clock signal from the processor. A x2 multiplier provides a 2 MHz clock to the 8-bit shift register, which in turn provides the dot clock. Additionally, the 2 MHz is successively divided through a divide-by-eight circuit then through a 12-bit binary counter to provide the remaining clock requirements.
15-8. CHARACTER GENERATOR. The character generator sequentially accesses that part of the RAM where character information is stored and causes the respective characters to be displayed on the screen. Since both the character generator and the processor share the same RAM, the two must be synchronized so they access the RAM during alternate half cycles of the master clock. The 1 MHz master clock signal, from the processor is used to synchronize the 2 MHz dot clock.
15-1
15-9. Characters are displayed on the CRT as eight-by-eight dot matrices. Thirty-two dot matrices, of which the last two are always blank, make one character line. Sixteen lines, of which the last line is always blank, complete the display area. Therefore, the total number of matrices available for character display is 30 x 15 or 450 matrices. The blank matrices and the blank line is used for horizontal and vertical retrace blanking, respectively. The display is generated by dot rows. As the CRT sweeps the first dot row of a character line, the character generator outputs a serial bit pattern of 1'sand O's that turn the crt intensity on and off. The result is a row of dots that when combined with the next seven rows form a character. 15-10. A select switch, on the data and address buses to the RAM, toggles at the master clock rate of 1 MHz. This results in the processor and the character generator having access to the RAM alternately every other 0.5 microseconds. The processor stores in the RAM an 8-bit word that represents the character to be displayed. The character generator scans the RAM in sequence with the CRT display scan. As each location in the RAM is addressed, the 8-bit word stored at that location is latched by the 8-bit latch. Seven of the bits in the latch are applied to the character ROM, the eighth bit is not used. The timing generator provides 3 bits which indicates which row of dots are being scanned. The 10 bits applied to the character ROM, define a specific dot row of a particular character. An 8-bit pattern, defining that row of the character, is parallel-loaded into the 8-bit shift register. These 8 bits are serially shifted out of the register, at a 2 MHz rate, as the CHAR GENZ-AXIS output signal.

SECTION 16 HIGH VOLTAGE POWER SUPPLY (A10)
16-1. GENERAL. CRT bias and drive voltages are provided by the high voltage power supply. The power supply converts a nominal 15 VDC input to output voltages of +4 kV and a-2 kV. In addition, control circuits for the CRT focus and intensity grids are contained in this power supply. The high voltage power supply block and schematic diagrams are shown in figures 16-1 and 16-2, respectively. 16-2. HIGH VOLTAGE SUPPLY. An 8 VDC at the center tap of the high voltage transformer is switched, through the transformer primary winding by the chopper, at a 20 kHz rate. The chopper drive signals originate in the low voltage power supply. One transformer secondary winding provides a 6.3 VAC CRT heater voltage. The other transformer secondary winding provides a 1 kV to a X4 multiplier and a X2 multiplier. The output of the X4 multiplier, a nominal +4 kV is the CRT anode voltage. A nominal -2 kV output of the X2 multiplier is applied to the intensity and focus modulators. The-2 kV is regulated by comparing a sample of the-2 kV to a 6.3V reference signal. The resultant signal controls the level of the DC input at the center tap of the high voltage transformer. A bias divider, on the transformer center tap, provides the HV CHOPPER BIAS signal to the low voltage power supply. 16-3. INTENSITY AND FOCUS CONTROL. An 87V zener diode and a resistive divider circuit provide the intensity and focus voltages. Each modulator provides variable output voltages, within their bias range, under the control of the low voltage INTENSITY TV and FOCUS TV input signals. The grid and focus voltages are stabilized by using DC control loops. The INTENSITY SAMPLE signal and the HV REF signal are compared, on the scope amplifier module, to an input control signal. The result of this comparison is the INTENSITY TV signal. In a similar manner, the FOCUS SAMPLE signal is compared, .on the scope amplifier module, to the input control signal. This results in the FOCUS TV signal.

High Voltage Power Supply A1O PWB Parts Location Diagram (Sheet 2 of 2)
SECTION 17
RF INPUT MODULE (A11)
17-1. General. The RF Input Module is subdivided into three isolate circuits; input protection and power meter, wideband amplifier and frequency converter and duplex generator. A block diagram of the RF Input Module is shown in figure 17-1 with its schematic shown in figure 17-2.
17-2. Input Protection and Power Meter. RF power to and from the system pass through this section to a common input/output RF connector (RF In/Out} attached to the module. In the generate or monitor operating modes the input protection relay is switched so that a low-loss 50-ohm path exists through the module. When the power monitor mode is selected, the WATT MTR EN line switches the relay so that the input is connected to a 50 ohm power termination. A detector across a portion of the load provides a DC level proportional to the input RF level. This level is amplified and made available to the system processor for the determination of input power. A thermal sensor monitors the load temperature and signals the processor when safe operating limits are exceeded. The processor in turn warns the operator that the RF input to the unit must be removed to prevent permanent damage.
17-3. If power in excess of 200 mW is applied to the system while operating in the50ohm load, protecting the system. A signal line (INPUT PROTECT ACT} to the processor results in an audiable and visual warning to the operator that the unit is in a protected mode. The warning ceases and normal operation resumes if the RF input is removed or if the power monitor mode is selected.
17-4. Wideband Amplifier and Frequency Converter. The wideband amplifier provides a leveled RF output from -3dBm to +13dBm in the generate mode and a +7dBm LO drive in the monitor modes over the 10 KHz to I GHz frequency range. Primary components of the leveling loop are; the input VCA (Voltage Controlled Attenuator}, the output level detector, and the level comparator. A level control voltage, proportional to the desired output level, is compared to the actual output level as determined by the level detector. The result of the comparison steers the VCA maintaining the detected output level equal to the requested output level. In the generate mode the control voltage is obtained from the front panel RF level control (AM Mod+ DC REF}. For generate AM, the modulation signal is summed with the DC control level, causing the RF output level to follow the modulation signal. Also, in the generate mode the signal from the output level detector(CARRIER+ MOD LVL} is made available for the determination of RF output power and percent of AM. A fixed reference voltage is switched to the level control input in the monitor modes giving a leveled +7d8m local oscillator drive.
17-5. The VCA on the wideband amplifier board covers the frequency range from 1 MHz to 1 GHz. For frequencies below 1 MHz, the VCA select circuit clamps the VCA in the minimum attenuation position and enables a low frequency VCA in the RF Synthesizer. Coincident with the enabling of the low frequency VCA, the time constant of the output RF level detector is increased assuring proper operation down to 10 kHz.
17-6. The wideband amplifier output is relay switched between the local oscillator port of the input mixer for the monitor and generate DSBSC modes, and the RF attenuator for the generate mode. An RF sample from the mixer local oscillator output terminal, at a nominal level of -20d8m, is provided to the duplex generator.
17-7. The frequency converter section consists of the input mixer, the first IF amplifier, and IF filters. In the monitor mode the desired signal is converted to 10.7 MHz by the input mixer. A two-pole input filter, IF amplifier, and a four-pole output filter select the 10.7 MHz component at the mixer output. The 10.7 MHz IF output of the converter is applied to the receiver module.

17-8. For DSBSC generation the modulation audio is applied to the IF port of the input mixer through an isolation network. With the output of the wideband amplifier switched to the local oscillator port, a DSBSC signal is present at the RF port. Switching the Step Attenuator to the RF output port makes the DSBSC signal available at the RF output. 17-9. Duplex Generator. The Duplex Generator output is a frequency component that is offset from the system monitor frequency by 0 to 10 MHz or by 45 MHz. The offset is obtained by mixing the -20d8m local oscillator signal from the wideband amp, which is already offset by 10.7 MHz, with a signal frequency from 10.7 MHz to 0.7 MHz or 34.3 MHz. 17-10. For the 34.3 MHz mixing signal, a single VCO is used. Tuning of the VCO is with the OFFSET FINE TUNE line from the front panel. Frequency modulation of the VCO is implemented by suming the OFFSET MOD signal with the tuning voltage. 17-11. For the 0.7 MHz to 10.7 MHz mixing signal a VCO with a frequency range from 35 MHz to 45 MHz is mixed with the 34.3 MHz VCO. The 35-45 MHz VCO is tuned by the OFFSET COARSE TUNE line from the front panel. 17-12. A sample of the offset frequency is made available to the frequency counter on the OFFSET FREQ line. The processor uses the frequency information to calculate and display the actual duplex frequency.

SECTION 18
FRONT PANEL INTERFACE MODULE (A12)
18-1. GENERAL. The front panel interface module contains the input buffers for front panel control to the processor. In addition, buffering and ranging circuits for external scope vertical/horizontal, SINAD, DVM, and frequency counter inputs ~re in this module. A block diagram and schematic diagram of the Front Panel Interface Module is shown in figures 18-1 and 18-2, respectively.
18-2. Input Coupling and Ranging. Scope inputs to the Range Attenuator are from the front panel jack (EXT IN) or from the internal modulation sources (INT SCOPE TO RNG SW). An INT/EXT relay selects the input path. The external path may be AC or DC coupled and is also the path for external DVM, Frequency Counter,. and SINAD inputs.
18-3. Four decades of attenuation from 1.0 to 0.001 are provided by the Range Attenuator. The input impedance of the attenuator is 1.0 megohm compensated for a bandwidth of 1 MHz. A unity gain buffer amp following the attenuator provides the drive for the DVM, Frequency Counter, and Scope Vertical Preamp circuits.
18-4. DVM Buffer. For DC measurements the DVM Buffer provides a 2-pole low pass filter with a minimum of 30 dB attenuation at 50 Hz. For AC measurements the bandwidth of the buffer is switched so that the attenuation at 10 kHz is less than 0.5 dB.
18-5. Frequency Counter Preamp. The Frequency Counter Preamp has sufficient gain for 30 mV rms sensitivity and provides hystersis for noise immunity.
18·6. Scope Vertical Preamp. A calibrated gain of 50 or a variable gain from 5 to 50 is provided by the Vertical Preamp. The gain is controlled from the front panel. From vertical scope positioning the DC bias point of the preamp is controlled by the front panel position control. Deflection sensitivity at the VERT FROM RNG SW output is 0.5 volt per division.
18-7. Scope Horizontal Preamp. A fixed gain of 5 in the Horizontal Preamp gives a horizontal input sensitivity of 0.1 volt per division. Horizontal vernier gain is implemented on the front panel, and horizontal positioning on the Scope Amplifier module. Deflection sensitivity at the HORIZ TO SCOPE AMPL is 0.5 volt per division.
18-8. Control and Display Interface. Front panel control information is input to the processor in 4-bit groups through the AF control bus. Priority encoders convert the multiposition switch positions (scope horizontal, frequency scan, and RF step attenuator) to 4-bit codes. The processor sequentially addresses each input buffer (AF ADAS BUS 0-3) through the Address Decoder. Data in the selected buffer is then transfered to the processor on the AF DATA BUS 0-3 lines while the AF BUS EN 2 signal is low. Two additional latches provide the processor control interface for the Range Attenuator, input switching, and DVM Buffer control.
18-9. AF BUS. The AF Bus consists of 4-bit tri-state bus AF DATA BUS 0-3. Individual input/output bus locations are addressed by AF ADD BUS 0-3. When AF BUS EN 2 is low, the function of the AF DATA BUS lines are determined by the address present on the AF ADD BUS lines.
18-10. LED CONTROL. Control output to the display, function, and modulation mode LEDs is by the AF BUS addressed 0, 1, and 2, respectively. Latch select outputs LSO, LS1, and LS2 are low to latch data present on the AF DATA BUS when the corresponding address is enabled on the AF ADD BUS. These latch select outputs and the AF DATA BUS are connected to the LED display board A14A1.

SECTION 19 10 MHz FREQUENCY STANDARD MODULE (A13)
19-1. General. The frequency Standard Module provides a stable 10 MHz source and the interface for an external 10 MHz input. A block diagram of the Frequency Standard Module is shown in figure 19-1 with its schematic shown in figure 19-2. 19-2. 10 MHz Oscillator and Control. The internal 10 MHz source is either a temperature compensated crystal oscillator (TCXO) or an optional ovenized crystal oscillator (OVXO). A voltage regulator on the module supplies the voltage to the oscillator and monitors the supply current. For the ovenized option, at power on the oven draws high current. As the oven warms up the current decreases, reaching some low valve when the operating temperature has been reached. A current detector illuminates the oven ready indicator when the current has decreased to the stabilized valve. The indicator is continuously illuminated with the TCXO. 19-3. Internal/External Switchover. With no signal at the external 10 MHz input jack, the internal oscillator is gated to the SYNTH 10 MHz and the external 10 MHz OUT signal paths. When an external 10 MHz input is applied the switchover circuitry detects its presence, removes the powerfro'm the internal oscillator, and gates the external input to the SYNTH 10 MHz and external 10 MHz OUT signal paths. The oven ready indicator is extinguished when the system is operating from an external standard.

SECTION 20 FRONT PANEL (A14)
20-1. GENERAL. The front panel assembly consists of a display board module and the analyzer operating switches and controls. A schematic diagram of the front panel assembly is shown in figure 20-1. 20-2. DISPLAY BOARD. The display board holds and decodes LED data. A display of 27 LEDs is driven by 24 drivers and three inputs from external sources. The keyboard is a 5-row X4-column matrix of momentary contact switches. Jumper connections on th,~ board are used to route signals between connectors. The display board consists of three latch/decoders, 24 LED drivers, and a 27 LED display. A display board block diagram is shown in figure 20-2. 20-3. The three latch/decoders hold and decode input data from the AF DATA BUS 0-3. Signals LSO- LS2 are latch selects that transfer data from the AF DATA BUS 0-3 to the corresponding latch. Only one LED at a time can be turned on by any of the three latch selects. Each driver is an open-collector device which sinks current through its respective LED.

SECTION 21 IEEE - 488 BUS CONTROL
21-1. INTRODUCTION 21-2. The IEEE Interface Option enables the use of the Communications System Analyzer as a programmable measurement instrument. When combined with a suitable programmable controller and applications software, the major funct'ions of the analyzer can be controlled or monitored via an IEEE-488 standard digital interface. Thus, repetitive test routines can be performed and the data recorded quickly and accurately with little operator interaction. 21-3. The interface characteristics conform to the specifications of the IEEE Standard Digital Interface for Programmable Instrumentation (IEEE Standard 488) which defines both the electrical and the mechanical interface. Control protocol is also defined by the specification. Control commands which are unique to the analyzer are described in detail in the following paragraphs of this section. 21-4. The controller for this application should be capable of reading and writing ASCII and control characters from and to the bus in accordance with the 488 specification. Application software is the user's responsibility as dictated by the controller selected, although interface and application assistance is available from Motorola. 21-5. The IEEE option package consists of an IEEE Interface module (AB) with a rear panel connector, an electrically programmable RF attenuator in place of the step attenuator on the RF Input Module (A11), a fourteen position rotary switch on the front panel in place of the step attenuator shaft, and one additional ROM memory IC on the Processor module (A9). 21-6. While in the local mode the IEEE-488 equiped system operates and performs the same as a standard system, except the maximum RF output level is reduced to +11 dBm from +13dBm. However, when the Remote Enable (REN) line on the IEEE Bus is activated many of the front panel controls are disabled and their functions placed under bus control. Refer to table 21-1 for a listing of those functions which can be controlled or monitored via the 488 Bus.

21-7. IEEE-488 BUS STRUCTURE
21-8. The following discussion briefly describes the 488 Bus operation. It is not a complete definition of the total bus structure or capability. For complete information a copy of IEEE Standard 488 should be obtained.
21-9. Bus Signals. The IEEE-488 Bus consists of 16 parallel lines. The lines are divided into three groups. Lines 0101-DI08, Data Input Output, form the 8-bit data bus for the bidirectional transfer of control and ASCII characters. Three handshake lines, Data Valid (DAV), Not Ready for Data (NRFD), and Not Data Accepted (NDAC), control the transfer of data on the data bus. The remaining five lines can be termed the bus management lines with functions as follows:
Attention (ATN)
Interface Clear (IFC)
Service Request (SRO) Remote Enable (REN) End or lndentify (EOI)
- When true the data bus carries an address or a comand when false it carries data.
- When true all devices on the bus are placed in a known quiescent state.
- Indicates a device on the bus needs service. - Enables the remote control feature of the devices on the bus. - Indicates the end of a multiple byte transfire.
21-10. Data Transfer. Each byte of data that is transferred across the data bus is synchronized with a
handshaking procedure. This· procedure allows devices with different data transfer rates to share the same
bus. The handshake cycle starts when the source device which has data to transfer checks for a false condition
on the NRFD line. When NRFD is false, all devices on the bus are ready to accept data. The source then puts the
data onto the data bus and sets the DAV to its true state. The acceptor devices input the data, set the NRFD line
to its true state, and when ready sets the NDAC line to its false state. Because the NRFD and NDAC lines are
wire-ORed the line will not go to the false state until all devices on the bus have released the line. Thus the
I
slowest device on the bus determines the transfer rate. When the NDAC line goes false the source devices sets the DAV false which in turn causes the acceptor devices to set the NDAC line true. When the acceptor devices
have completed processing the data byte just received they allow the NRFD line to go to the false state
completing the handshake. As the data transfer continues the cycle repeats for each data byte.
21-11. Bus Address. Each device on the bus is assigned a four bit address by the programer. The address assigned to the device is set by an address switch within the device. On the analyzer the address switch is on the IEEE Interface Module. Only the top four switches are used to set the address. The fifth switch is unused. To set the address use the binary equivalent of the address number and set the switches to the ON position for a logic 1. The least significant bit is the top switch.
21-12. Programming
21-13. Programing the system analyzer consists of first addressing the unit as a listener, transferring the control commands to the unit, and then sending a command termination sequence. To obtain data from the system, the pertinent control commands are first transferred to the unit and then the unit is addressed as a talker. As a talker the system outputs onto the bus the data requested by the control commands.
21-14. The bus controller is the central part of the automatic system. The program, consisting of sequences of analyzer control commands and sequences of controller instructions for handling the return data, is contained within the controller. The user must initially write the program so that the desired test sequences and data outputs will be obtained. The following paragraphs define the instruction set and data formats that can be used to control or will be returned from the system analyzer-The user must insure that the controller is compatible with the IEEE-488 Standard bus and that its program is correct for the instruments on the bus.
I
21-3
21-15. Command Structure. Each command consists of a two letter definition prefix followed by a numeric data field. The data field will vary in length and structure according to the definition prefix as shown in table 21-3. Spaces may be inserted anywhere in the command but are not required. Each letter or number of a command is transferred from the bus controller to the analyzer in ASCII format. ASCII defines a 7-bit digital code for each letter, number, and symbol commonly used in computer programming.
21-16. The first letter of the two letter prefix identifies a command category with the second letter identifying a particular command within that category. A listing of the command categories and the corresponding f;rst letter is provided in table 21-2. A complete list of commands is shown in table 21-3.

Data limits and accompanying units are given in table 21-3. The data field is optional or not allowed for certain commands.
21-18. Data Sign. The data sign is a single'+' or'-' character indicating the sign of the data value. The sign may be omitted for positive value data.
21-19. Data Value. The data value field is restricted to the numbers 'O' through '9' and'.'. A maximum of five digits to the right and to the left of the decimal point are allowed. The decimal point can be omitted for integer values. If the value field is omitted, it is assumed to be zero.
21-20. Exponent. The presence of the "E" character in the exponent field indicates that the data value is to be multiplied by 10 raised to the power following the "E" character. If the "E" is omitted the exponent is assumed to be 10° or 1.
21-21. Exponent Sign. The exponent sign is a single + or - character and can be omitted for positive exponent values.
21-22. Exponent Magnitude. The exponent magnitude is a single character 0 through 9. If the exponent magnitude is omitted, it is assumed to be zero.

21-24. Command Strings. A command string consists of either a single command or multiple commands in succession with or without embedded spaces. A command string must be terminated with a carriage return and a line feed character.
21-25. Command Types. Each command is one of three basic types, control selects (C), data entry (D), and output requests (0). Type information for each command is listed in table 21-3.
21-26. Control Selects. Control select commands select front panel switch settings. Some of these commands do not require accompanying data, such as toggle switch commands.
21-27. Data Entry. Data entry commands replace manual entry of data through the keyboard. All of these commands require data in the data field.
21-28. Output Requests. Output request commands allow data that is normally displayed on the CRT to be transferred to the controller. Accompanying data is not required with output requests. The data limits and units listed in table 21-3 for these commands refer to the return data. Output request commands cause the analyzer to go to the proper display, function, and mode to acquire the designated reading. These states are listed in table 21-3. The measurement however, is not made until a trigger command 'T' has been sent from the controller. The trigger command causes the measurement to be made and the data held for transmission to the controller. Then when the controller addresses the analyzer as a talker the data is output to the controller. A reading can be retaken for any number of triggers without repeating the output request. The request is lost however, when any command changing the display, function, or mode is sent.
21-29. Trigger Command. The trigger command is the exception to the two character command prefix. This command is simply the letter 'T' usually sent immediately following the output request command. If no output request is pending, the trigger command is ignored.
21-30. Return Data. The data returned from the analyzer is formatted similar to the control data as shown:
±
n
E
-n
/ I " ' ~
DATA SIGN DATA VALUE EXPONENT SIGN EXPONENT MAGNITUDE
The data is always returned in this format with a single exception. Data for the "RP", signal present, command is returned as a single digit having a value of "O" or "1".
21-31. Data Sign. A+ or - character indicates the sign of the return data.
21-32. Data Value. The data value is 1 to 5 digits in length with leading zero supression and no decimal point.
21-33. Exponent and Exponent Sign. The letter 'E' followed by a'-' character is always transmitted with return data.
21-7
21-34. Exponent Magnitude. The exponent magnitude is a single digit with a value from Oto 9. The digit indicates the negative power of ten that is to be multiplied with the data value to obtain the units listed in table 21-3.
21-35. Programming Commands. Table 21-3 lists the programming commands available for the system analyzer. The table identifies the category and type of command, the data limits and units, the command function, and any display, function, or mode change that would occur.
21-36. Terminal Mode. When the command 'CD12' is used, the system terminal mode is enabled. The terminal mode allows the analyzer's CRT display and keyboard to perform as a limited function 1/0 terminal. Possible uses for the terminal mode would be to provide test instructions to a test operator at an auto test station.
21-37. Display Format. Once the 'CD12' command has been sent the terminal mode has been entered. All further ASCII valid characters sent from the controller will appear on the CRT display. The total display area on the CRT is 15 lines of 30 characters each. Character entry on the CRT is on the bottom line. Each line feed character causes the bottom line to move up one place. If more than 30 lines are entered, the top lines are lost off the top of the display. A list of valid ASCII characters for the display is provided in table 21-4 All invalid characters are ignored in the terminal mode.
21-38. Keyboard Entry. In the terminal mode the keyboards on the analyzer may be used to input data to the bus controller. The ten numeric keys and the left cursor key have predefined ASC II characters. The character corresponds to the number on the key for the numeric keys. For the left cursor key, carriage return and line feed characters are sent. The down cursor key causes a bus service request to be generated regardless of the operating mode. Thus this key could be used to halt an automatic test sequence.
21-39. The remaining pushbuttons are defined, prior to entering the terminal mode, with the use of the keyboard control commands listed in table 21-3. Each key is assigned an ASCII character by following the Kn command prefix with the decimal equivalent of the binary ASCII code for that character. A list of valid ASCII characters and their binary and decimal equivalents are listed in table 21-4. 21-40. Data that is entered from the keyboard is stored in a 9 character buffer until addressed by the bus controller. If more than 9 keypresses occur before the controller accesses the analyzer, the excess inputs are lost. Once the controller has addressed the analyzer, the analyzer transmits the character data to the controller. The analyzer will continue to transmit, or hold up the bus handshake if no keys have been pressed, until the left cursor key is pressed. Thus every data string entry from the keyboard must terminate with the left cursor key. As the data is transmitted to the controller it is also entered onto the CRT display.
21-41. Terminal Mode Exit. An ASCII end of transmission character (EOT) sent from the controller will terminate the terminal mode. When the mode is terminated the analyzer returns to the Gen/Mon Mtr display, and is ready to accept new command inputs.
21-42. Error Messages. _Error messages are generated by the analyzer to help the programmer troubleshoot his program. As control commands are received by the analyzer, they are decoded to determine the command sent. If the analyzer is unable to decode the command it generates an error message and ignores all succeeding commands. To clear the error condition the bus controller must address the analyzer as a talker so that the error message will be transferred to the controller.

21-43. The format of the error message is:
ERROR nn (CR)(LF)
The two digit number nn defines the error condition as listed in table 22-5. The carriage return (CR) and line feed (LF) characters are the termination sequence used by analyzer whenever it transmitts information. All characters are ASCII coded.

Condition

21-44. To effectively utilize the error message capability of the analyzer it is necessary to address the unit as a talker after the transmission of each command string. The bus controller must then be programmed to recognize the error message and to decode the error number. A successful data transmission will send back an error code 00 when addressed as a talker. The controller should be programmed to ignore error 00 and to display any other error to the operator. Of course if a valid output command followed by the trigger command was sent, the talker address will result in the requested data being output to the controller.
21-45. Service Requests. There are only two conditions that will cause the analyzer to generate a service request (SRO) on the bus. If a SRO is generated it must be cleared by a serial poll of the analyzer. The serial poll is a bus command which results in a data byte being sent to the controller from the analyzer. The data byte indicates the cause of the SRO. Table 22-6 lists the SRO causes and the corresponding serial poll data.

21-46. Programming Considerations. The flexibility of the IEEE-488 option is reflected in the number of programming commands. To use these effectively and efficiently, certain programming practices should be followed. The following paragraphs present the major considerations for effective programming.
21-47. Generate Mode. For accurate level control it is besttospecifythegeneratefrequency prior to the RF output level. For example, the command string:
CGGFIOOGL5 sets the generate mode, a frequency of 100 MHz and an output level of +5 dBm.
21-48. Code Synthesizer. Before enabling the output of the code synthesizer with an MS, ME, or MK command, all the necessary parameters must first be defined. Table 21-7 lists the modes and their controlled parameters that need to be defined. It should be noted that these parameters do not need to be defined each time a mode is selected, only when they are to be changed for that mode.

21-49. Modulation. The system analyzer is capable of modulating with three simultaneous sources. The commands ME, MK, and MS only affect their individual portion of the total output. Thus to avoid inadvertently having an unwanted modulation source enabled it is recommended that all three source values be defined together. For example;
CFMKMSME20 selects the FM mode, disables the 1 kHz and code synthesizer modulation, and set 20 kHz deviation from the external input. The external input must be applied to the analyzer prior to sending this command.
21-50. For the generate AM mode the frequency and output level must be defined prior to selecting the modulation level. The following command string is of the proper sequence to obtain 30% AM at100 Mz with a level of -100 dBm:
CGGF1 OOGL-1 OOMEMSMK30
21-51. The bandwidth control commands, RN and RW, range the generate FM modulator sensitivity. For greater resolution and faster set up time for deviations less than 20 kHz use the narrowband 'RN' command. Above 20 kHz deviation the wideband 'RW' command must be used.
21-11
21-52. Measurements. To obtain correct monitor mode data it is necessary to first set the frequency, bandwidth, and image prior to making the reading. Thus, it is a good practice to always place the request for a reading as the last command in the string. For example the command string:
CMRNRHGF95.5RET selects the monitor mode, narrowband, high image, and 95.5 MHz center frequency. The 'RET' command asks for a frequency error reading and triggers the analyzer so that the reading will be made. 21-53. General. Overall, programming the analyzer involves the same steps as are involved when using it manually. A program can be fairly easily obtained by first performing the desired test sequence manually noting each time a setting is changed and a reading made. The program is then simply a duplication of the manual steps with control commands substituted. 21-54. R2002B Analyzer Configuration The R2002B analyzer differs in configuration from the standard R2001 B in the following manner:
A11 Module: The manual attenuator AT1 is replaced with a programmable version (P/N RTL-4064A) A new ribbon cable assembly connected to the AS module provides control signals for the attenuator. The module is reidentified for ordering purposes as RTC-10038. A9 Module: Additional memory for the IEEE program is added by adding U36 (E-PROM TMS 25L32). Front Panel Assembly A14: Rotary switch S19 is added for control of the RF Input/Output level. The switch P/N is 40-P04127T001. Module AS is added to the analyzer (see Section 14 for details). Ribbon cable assembly 30-P04147T001 is added from the AS module to the rear panel of the analyzer to provide 1/0 signals.

MOTOROLA BATTERY PACK
MODEL RTP-1002A
1. DESCRIPTION
The RTP-1002A is a battery pack and charge1 designed to be mounted to the back of the R-2001A Communications System Analyzer. The unit contaim battery capacity to operate the R-2001 A for approximately one hour. A constant current charging system is capable of recharging the batteries in 16 hours.
2. I NSTALLATION
2.1 The RTP- 1002A Battery Pack is quickly installed on the R200 1A/ B/C Communication System
Analyzer. With the R2001 disconnected from the AC line, remove the blower AC connector from the socket on the rear panel of the unit. For R2001A units only, remove six screws holding the blower assembly to the rear of the unit. Lift the blower assembly from the rear panel and set it aside. Replace the six screws in their holes to avoid loss. For R2001B/C units, loosen the two thumbscrews and move the two clips aside that hold the blower to the rear panel. Lift the blower off and set it aside. noting the position of the blower in relation to the two locating pins on the rear panel. Reverse this procedure to reinstall the blower. Please affix caution label (PIN 54-80379A76) to the rear panel of your R-2001.
2.2 Place the tabs on the left edge of the RTP- l002A Battery Pack into the slots in the left feet on the
rear panel of the R2001. Two captive screws on the right edge of the battery pack engage threaded holes in the right feet on the rear panel. Tighten these screws snugly, but do not overtighten. Install the cable from the battery pack into the DC IN jack on the R200l rear panel , and reconnect the AC line cord .
3. OPERATION
3.1 The RTP-1002A Battery Pack is automatically engaged when no ac power is present, and the
power switch is either in the ON or STANDBY positions. When ac power is applied, the R-2001A automatically switches the RTP-1002A Battery Pack out of the circuit and draws its power from the ac power source.
3.2 When the power switch is in the OFF or STANDBY position and ac power is applied to the
R-2001A , the RTP-l002A Battery Pack draws de current from the R-200IA to activate the charging circuit. The charging circuit delivers approximately 750 mA of current until the battery voltage reaches 14 volts. As the battery voltage reaches 14 volts, the current drops to approximately 25 mA and the high-charge indicator LED extinguishes.
3.3 Whe n the R-2001 A systems analyzer is used with the RTP-1002A Batte ry Pack , it is recommended
to keep the power switch in the STANDBY position whenever possible. This extends the time the battery is able to operate the R-2001A Communications System Analyzer. The low trickle charge rate enables the batteries to be left on charge indefinitely without damage due to overcharging.
3.4 If long periods of operation from the AC line a re anticipated under conditions of high ambient
temperature, it is recommended that the RTP-1002A Batte ry Pack be removed and the blower assembly reinstalled.
