WARNING
Changes or modifications not expressly approved by
RF Technology could void your authority to operate
this equipment. Specifications may vary from those
given in this document in accordance with
requirements of local authorities. RF Technology
equipment is subject to continual improvement and
RF Technology reserves the right to change
performance and specification without further notice.
Operating Instructions
1.1 Front Panel Controls
1.1.1
MON. Volume
The Mon. Volume control is used to adjust the volume of the internal loudspeaker and
any external speaker connected to the test socket. It does not effect the level of the 600
Ohm line or direct audio output.
1.1.2
MON.SQ
The MON. SQ. switch allows the normal squelch functions controlling the monitor
output to be disabled. When the switch is in the MON. SQ. position the audio at the
monitor speaker is controlled by the noise detector. The CTCSS, carrier and external
squelch functions are disabled. This can be useful when you are trying to trace the
source of on channel interference or when setting the noise squelch threshold. The
audio from the 600 Ohm line and direct outputs is not effected by the switch position.
1.1.3
N.SQ
The N.SQ trimpot is used to set the noise squelch sensitivity. Use the following
procedure to set the noise squelch to maximum sensitivity.
(a) Set the toggle switch to the MON.SQ. position and set the MON VOLUME control
to 9 o'clock.
(b) Turn the N.SQ. adjustment counter clockwise until the squelch opens and noise is
heard from the speaker. Adjust the VOLUME to a comfortable listening level.
Page 4
RF Technology R50
1 OPERATING INSTRUCTIONS
1.1.4 C. SQ
(c) In the absence of any on channel signal, Turn the N.SQ. screw clockwise until the
until the noise in the speaker is muted. Then turn the screw two additional turns in the
clockwise direction.
1.1.4
C.SQ
The C.SQ trimpot is used to set the carrier squelch sensitivity. Carrier squelch is useful
at higher signal levels than noise squelch and can be used from 1 - 200 uV input.
It is provided mainly for use in fixed link applications where a high minimum signal to
noise ratio is required or where very fast squelch operation is required for data
transmission. The carrier squelch will open and close in less than 2 mSec.
In most base station applications carrier squelch is disabled by turning the adjustment
counter clockwise until the screw clicks.
The carrier squelch may be set to a predetermined level with the TecHelp software or
by using the following procedure:
(a) First turn the adjustment fully counter-clockwise. Then set the noise squelch as
above.
(b) Connect a source of an on channel signal with the desired threshold level to the
receiver's RF input.
(c) Turn the screw clockwise until the SQ LED goes OFF. Then turn the screw back
until the LED just comes ON.
1.1.5
LINE
The LINE trimpot is used to set the line and direct audio output level. It is normally set
to give 0 dBm ( 775 mV ) to line with a standard input signal equal to 60% of
maximum deviation at 1 KHz. The level can be measured between test socket pins 6 &
1 and set as desired.
1.2 Front Panel Indicators
1.2.1
PWR LED
The PWR LED shows that the dc supply is connected to the receiver and that the
microprocessor is not being held in a RESET state.

1.2.2 SQ LED
1.2.2.1
SQ LED
The SQ LED comes on when the audio to the line and direct outputs is un-squelched.
The LED and squelch function are controlled by noise, carrier and tone squelch
circuits.
1.2.3
ALARM LED
The ALARM LED can indicate several fault conditions if they are detected by the self
test program. The alarm indicator shows the highest priority fault present. See Table

Receiver Options
There are many software selectable options. Some options are selected on a per
channel basis, and some are defined globally (i.e. the parameter is fixed irrespective of
which channel is selected). Below is a description of these global parameters
2.1 Serial I/O Parameters
There are two serial ports. There is the main serial port which is brought out to the
front panel connector. This is referred to as PORT0. There is another serial port
which is for factory use only. It is referred to as PORT1.
The baud rate, parity, and whether hardware flow control is enabled can be defined for
PORT0. PORT0 is set by default to 57.6Kbps, with No parity, and No Hardware Flow
Control.
Page 6
RF Technology R50
2 RECEIVER OPTIONS
2.2 Receiver Low Battery Level
2.2 Receiver Low Battery Level
This is factory set to 24.0V, and defines the level of the DC supply that will cause an
Receiver dc supply low alarm.
2.3 Audio High Pass (Notch) Filter
At the audio output ports, the sub tone (CTCSS) can be notched by a high pass filter,
this high pass filter can be software selected as enable or disable (the filter was
bypassed). The default factory setting is audio high pass filter enable.
2.4 Audio Response
The output audio frequency response can be selected as 750uSec. De-emphasis or flat
response, the default factory setting is 750uSec. De-emphasis.
2.5 LOOP Volts Select
The receiver can key up the transmitter with a DC current between Line+ and Line- of
the audio output terminals. If this option is selected enable, it will be active by the
squelch switch, then a 12Vdc supply is applied to the pair through 660 ohms of source
impedance. If this option is disable, the loop is not used. The default factory setting is
LOOP VOLTS enable.
2.6 COS Polarity Select
The COS (Carrier Operated Switch) can be selected as on with Signal or on with no
Signal. The default factory setting is COS on with Signal.
2.7 COS Source/Sink Select
The COS can be used as a DC source or a free switch, if the Source option is selected,
a 12Vdc voltage will be applied between COS+ and COS- terminals when the COS is
off. The default factory setting is COS Source.
2.8 Channel Selectable Parameters
Each channel defines two complete set of parameters. One set of parameters is used
when a transmitter keys up from the PTT-in input, and the other set is used when the
transmitter keys up from the LOOP-in, the PTT switch, or the microphone PTT input.
Each set defines what frequency to use, what CTCSS sub-tone (if any) to use, what
RF Technology R50
Page 7
3 RECEIVER I/O CONNECTIONS
3.1 25 Pin Connector
maximum line deviation to use, what tone deviation to use, what transmit delay (a
delay applied from PTT-in or LOOP-in to transmission), what transmit tail (delay
from PTT-in, or LOOP-in, to transmission being stopped, and No-TONE period (a
period of extra transmission in which No Tone is applied after PTT-in or LOOP-in has
been released.
As well as these parameters, which Line (or Lines) can be selected, and whether the
Lines should have Flat frequency response or have Pre-emphasis applied. Also, it can
Enable or disable the extra 20dB gain pad.
Note that both Line1 and Line 2 can be selected (each with or without pre-emphasis),
and if so, then the two signals will be mixed, and the Line potentiometer will adjust
the level of them both.

The pinout for the connector has been chosen so that a straight-through BD9 male to
DB9 female cable can connect the transmitter to any male DB9 serial port on an IBM
PC compatible computer.
Note that for connection to a modem, a cross-over cable will be required.
Channel Programming and Option Selections
Channel and tone frequency programming is most easily accomplished with RF
Technology Eclipse50 software. This software can be run on an IBM compatible PC
and can be used to calibrate a T50, R50, and PA50 as well as program channel
information. See the Eclipse 50 users manual for further information.
But the R50 also has its own stand-alone high level interface, which can be accessed
from a VT100 compatible terminal, or terminal emulator (such as HyperTerm which is
available as a standard accessory with Windows).
The pertinent aspects of this High Level Interface are described below.
4.1 Setting Options
Note that any text in italics, represents data output by the R50 firmware, rather than
command line data sent to the R50 firmware.
The R50, after powering up, will issue a command prompt of the form:
R50>
Via a terminal, or a terminal emulator, a user can type various commands in. The basic
command to read parameters is:

Table 6: Some User Defined Parameters
Note that the parameter names have been shown in upper case, but they can be typed
in upper or lower case.
A parameter can be changed, or added, by typing
R50> set par parameter_name=parameter_value
As for parameter names, the parameter value can be Upper or Lower case if it is a text
value, as against a numeric value.
4.2 Setting Channel Parameters
One can read the data from an existing channel by entering the command:
R50> read chan chan_number
Where chan_number is a number from 0 to 99.
Entering new channel values, or modifying existing ones is possible from the
command line interface, but it is not recommended. It can be done by typing the
following at a command prompt:
R50> set chan chan_number parameter_list
Where chan_number is a number from 0 to 99.
The format of the parameter_list is quite complex. It has 14 fields. Each field can be
separated by a colon(:), comma(,), space, or tab.
For example set chan 0 25.0:35.0,100.0,120.0,0,5,2,0,5,2,10,11,0,3

Field2:
Transmit Frequency(in MHz) if the exciter is keyed up by anything but
PTT-in being asserted. This is 35.0 MHz in the example.
Field3:
CTCSS Tone(in Hz) if PTT-in is asserted. This is 100Hz in the example.
Field4:
CTCSS Tone(in Hz) if the exciter is keyed up by anything but PTT-in
being asserted. This is 120Hz in the example.
Fields 5,6,7: These define the start-up delay (in hundredths of a second), the transmit
tail (in seconds), and the no tone period (in tenths of a second) if the exciter keys up
from PTT-in being asserted.
Fields 8,9,10: These define the start-up delay (in hundredths of a second), the transmit
tail (in seconds), and the no tone period (in tenths of a second), if the exciter keys up
from anything other than PTT-in being asserted.
Field 11: Selects the line parameter if PTT-in being asserted caused the exciter to key
up. In the example it has disabled the 20dB gain pad, and enabled pre-emphasis on
Line 2 (Line 1 is disabled).
Field 12: Selects the line parameter if anything other than PTT-in being asserted
caused the exciter to key up. In the example it has disabled the 20dB gain pad, and it
would enable pre-emphasis on Line 1 and Line2 (i.e. audio on each input is mixed).
Field 13: Selects the Tone deviation and the Maximum Line deviation if the exciter
keys up from PTT-in being asserted In the example, it has selected the default
maximum line deviation (5kHz), and the default tone deviation of 750Hz. (See Tables
7 and 8)
Field 14: Selects the Tone deviation and the Maximum Line deviation if the exciter
keys up from anything other than PTT-in being asserted In the example, it has
selected a maximum deviation of 2.5kHz, and a maximum tone deviation of 375Hz.
(See Tables 7 and 8)

D102, D103, and D104 represent the three front panel LEDs.
5.2 Microprocessor (Sheet 2)
Sheet 2 describes the basic microprocessor circuitry.
The core CPU is the Motorola XC68HC12A0. It is configured in 8 bit data width
mode.
The CPU is clocked by a 14.7456MHz crystal oscillator circuit (top left) comprising
the JFET Q202, and two switching transistors Q203 and Q204.
The CPU contains an 8 channel A/D converter whose inputs are identified as AN0,

AN6 is used to sense the noise squelch level setting.
AN5 is used to sense whether or not the dc supply is within spec or not.
AN4 is used to sense the audio from the discriminator, so the R50 receiver can be used
as a deviation meter.
AN3 and AN1 are inputs from the PLL circuits that sense the bias voltage on the VCO
control varactor for each VCO.
AN2 is used to sense the carrier squelch level setting.
AN0 is used to sense the RF input signal strength which is detected by the IF chip.
FRDY is an output from the flash. It goes low when the Flash starts to write a byte of
data, or erase a block, or erase the whole chip, and it returns to its default high state
when the action requested has completed.
FPSW1, FPSW2 and FPSW3 are three pins that have been reserved for future use as
switch inputs.
LOOP/VOLTS_SEL is a CPU output that when high applies 12V of dc feed to the
audio output.
Page 12
RF Technology R50
5 CIRCUIT DESCRIPTION
5.2 Microprocessor (Sheet 2)
LINE_LEVEL_U/D and LINE_LEVEL_INC are CPU outputs which are reserved for
controlling a digital potentiometer in future.
COS_VOLTS_ON/OFF is a CPU output that when high applies 12VDC feed to COS+
terminal, so that the COS can be selected as +12VDC source or a free switch.
COS_POLARITY is CPU output that when low turns Opto-coupled transistor switch
U601on. It is controlled by the noise squelch detect, carrier squelch, or external
squelch signal
SQ is a CPU output that when low turns 600W line and direct audio path on. It is
controlled by the noise squelch detect, carrier squelch, or external squelch signal
N_BLK_EN is a CPU output that when low turns noise blanker option off.
CTCSS_SEL is a serial bus select pin. It is used to select the FX805 chip(U500),
which is used to decode CTCSS tones. (see 5.5)
PLL_SEL is a serial bus select pin. It is used to select the PLL chip in the PLL circuit
(U302). (See 5.6)
RCV_ADSEL is a serial bus select pin. It selects the quad Digital to Analogue
converter (DAC) that sets the levels for the 12MHz reference oscillator bias voltage,
21.855MHz oscillator bias voltage, noise squelch comparator bias voltage and the
LCD bias circuit. (see 5.4)
CH_EN is a serial bus select. It is brought out to the rear panel and is used to interface
to the channel encoder on the rear daughter-board. (See 5.1)
FLAT and DE_EMPHA are outputs logically inverted each other, when FLAT pin
low, the audio output is flat response, when DE_EMPHA pin low, audio is 750uSec
de-emphasized.
F0_PLL is the F0 outputs of the PLL chip divided by 100. They should be 312.5Hz
square waves, except for brief periods when frequencies are being changed. (See 5.6)
MON_SW is used to sense front panel MON.SQ switch.
LCD_DB7 is an input used to sense if the LCD display module is busy processing the
last command sent to it.
ECLK is a pin that at start-up only, should have the CPU system clock of 7.3728MHz
on it.
SQ_LED, ALARM_LED, are CPU outputs that drive (when low) the SQ LED, and
the ALARM LED on.
T/R_RELAY_H is a spare pin which is not used in R50 receiver.
SCLK, and MOSI are used as the core of a serial bus. SCLK is a clock pin, and MOSI
is a bi-directional data pin.
RF Technology R50
Page 13
5.3 RF Section (Sheet 3)
5 CIRCUIT DESCRIPTION
DBGTX_TTL, DBGRX_TTL are RS232 transmit and receive (TTL) data pins which
are connected to the debug port after conversion to/from RS232 compatible voltage
levels by U202 and U201.
TXD_TTL, RXD_TTL, RTS_TTL, CTS_TTL, DTR_TTL, DSR_TTL, are RS232
data pins which are connected to the main front panel serial port after conversion
to/from RS232 compatible voltage levels by U202 and U201.
N_DET is used to sense the noise squelch output of the receiver section. (see
SUBTONE_IRQ is used to sense the subtone decoded comes from the FX805 (U500).
INT is the CPU interrupt input pin which is used to detect the external squelch signal.
BKGD is a bi-directional I/O pin used to communicate with the core of the CPU. It is
connected to the debug port and is utilised by specialised hardware to control the CPU
externally, even without any firmware being present in the Flash.
The RESET pin is both a low active input and a low active output to the CPU. If
generated externally to the CPU, it forces the CPU into reset, and if the CPU executes
a RESET instruction this pin will be driven low by the CPU.
Whenever there is insufficient volts (< 4.65V) on pin 2 of the MC33064D (U203), it
will keep its RES output low. After the voltage has met the right level it will assert its
output low for another 200 milliseconds. Thus the CPU will be held in reset until
VCC is at the correct level. Thus the PWR_OK LED will only light when VCC is
within specification, and RESET has been released.
S200 is a momentary push-button switch that, when pressed, will cause the CPU to be
reset.
MON_SQ is a CPU output to set the monitor speaker on or off
LCD_RS, LCD_R/W, and LCD_E are reserved for interfacing to an LCD display
module. Note that this feature has not been implemented.
U205 is used to select whether the Flash or RAM is to be read or written.
U207 is a single supply, 5V, TSOP40 Flash chip of size 8, 16, or 32 Megabits, and is
used to store the firmware.
U208 is a 1, or 4, Megabit Static RAM in an SOP-32 package, and is used for both
code and data. The code in the RAM is copied from the Flash, at start-up.
5.3 RF Section (Sheet 3)
Sheet 3 is a schematic of RF section, which itself refers to two other subsheets.
U301 is a quad Digital to Analogue converter (DAC), OUTA (pin2) is used to adjust
the 3rd local oscillator frequency. OUTB (pin1) is used to adjust frequency of the
12MHz reference. OUTC(pin16) is used to set the noise squelch comparator offset

voltage. OUTD (pin15) is used to set the LCD bias voltage, this feature is not used in
this version. Communication between U301 and MicroController U204 is via the
serial bus.
U302 is a dual channels PLL chip, X301 is the reference for both PLL channels, PLL
channel 1 is for the 1st VCO, channel 2 is for the 2nd VCO. C315, C317, C327,
R316 and R317 are components of loop filter for the 1st VCO, C316, C328, C329,
R330 and R331 are for loop filter of the 2nd VCO. U303A, U303D are buffers that
send the bias voltage of two VCOs to MicroController U204.
U304A, U304B convert the F0LD of the PLL chip to a square wave by a division of
100, and send the signal to MicroController U204.
5.4 Receiver Section (Sheet 4)
RF input signal (25MHz-50MHz) is filtered by a high pass filter (C401, C402, C403,
C407, C415, C416, C417, C419, C420 and L401, L404, L405, L406) and a low pass
filter (C404, C405, C406, C421, C422 and L402, L403, L407, L408). Q401 is the
front-end amplifier, capacitors and coils between Q401 and C440 provide additional
filtering for RF signal amplified by Q401. MX401 is a double balanced mixer which
converts the RF signal to the 1st IF, the frequency of the 1st IF is at least three times
higher than the highest RF frequency to obtain a good image and spurious rejection. In
R50 receiver, the 1st IF frequency is 246MHz.
Q402 is used to amplify the 1st IF signal, FIL401 is a SAW filter which provides an
excellent spurious rejection for the 1st IF. The filtered IF signal is then fed to a double
balanced mixer MX402, the output of MX402 (the 2nd IF) is amplified by Q403, the
2nd IF frequency is selected at 21.4MHz to avoid the interference from in band RF
signal.
Q404 is a gate of the noise blanker, the gate is controlled by the impulse noise
detector.
FIL404 and FIL405 are two 21.5MHz crystal filters which can be equivalent as a four
pole crystal filter, the filer provides minimum 40dB attenuation at adjacent channel
frequency. C448, C477, L423 and components between FIL405 and U401 are
matching network for the filter.
U401 is IF receiver IC which includes mixer, oscillator, amplifiers and discriminator.
The frequency of oscillator is 21.855MHz, it can be tuned by the 3rd_LO_ADJ
voltage.
The product of mixer is 455KHz, build in amplifiers of U401, FIL402 and FIL403
provide sufficient gain and adjacent channel rejection for 455KHz IF signal to be
discriminated.
Pin9 of U401 is recovered audio output, C411, C412, C413 and R441, R444 and
U402A are working as a high pass filter to eliminate the audio frequency, U402B
amplifies the FM noise signal, D403 and C438 convert the noise level to a DC voltage.
U402C works as a comparator, the offset voltage can be set by the OUTC of U301.

5.5 Voltage Controlled Oscillator (Sheet 5)
5 CIRCUIT DESCRIPTION
Pin8 of U401 is the other recovered audio output which can be muted by pin5,
discriminated audio signal is amplified by U605A to a sufficient level for line level
detector, then fed into Audio Section (Sheet 6).
Pin7 of U401 is the Radio Signal Strength Indicator (RSSI) output, U402D is a buffer
for send RSSI voltage to MicroController.
Q405 and Q406 are amplifiers for impulse noise signal, the impulse noise is then
detected by D401 and U403, C489, R450 and U404 form a 2uSec noise blanking pulse
when the impulse noise is detected. Q408 converts the CMOS level to a required
switch level to control the noise blanker gate Q404.
U303B and Q407 work as gain control circuit to reduce the Intermodulation which is
produced from impulse noise amplifiers.
5.5 Voltage Controlled Oscillator (Sheet 5)
There are two similar VCO circuits in this sheet, the difference between these two
VCO is component values, so only one VCO circuit is illustrated in this section.
Q501, C532, C533, C534 and L501 are working as a Colpitts oscillator, the frequency
of the oscillator is decided by the tuning voltage of a varactor D501 which comes from
the loop filter of the 1st PLL. Q503 is used to reduce the noise on power supply. D503,
R517 and C519 are working as AGC circuit to improve output of the VCO signal.
MMIC amplifier MA501 provides about 20dB gain for the VCO signal and feeds it to
the PLL chip. MA502 and MA503 provide about 30dB gain of the VCO signal to
drive the double balanced mixer MX401, Q506 and those components of which value
with "*" are not used in this version, they will be used in case of higher drive power
which is required by some high LO level mixer.
5.6 Audio Processing Section (Sheet 6)
U605B, R642, R643, R644, C626, C627 and C628 are working as a 3KHz low pass
filter, in addition, the discriminated audio signal level from U605A is attenuated by
the low pass filter to fit the dynamic range limitation of CTCSS chip U602.
U602 is a CTCSS tone encoder and decoder. The integrated circuit is also capable of
generating and receiving DCS signals, but at this stage this has not been implemented.
The CPU accesses U602 via the serial bus using MOSI, SCLK, and the low active
Select signal CTCSS_SEL.
4MHz crystal X401 is used as the reference of the CTCSS decoding. The build-in high
pass filter of the audio path (Pin 10 to Pin 11) can eliminate the subtone, this filter can
be bypassed by the MicroController. The subtone output from Pin17 is amplified by
U605C, through C604 connected to the DB25 terminal on rear panel.

5 CIRCUIT DESCRIPTION
5.7 Power Generator Section (Sheet 7)
U609B, U607A and U607B are working as a flat/de-emphasis response switch, it can
be selected by control signal FLAT and DE_EMPHA from the MicroController U204.
U607D and U607C is the squelch switch for line output and speaker.
U609C is the amplifies for 600W line output, U609D is the amplifier for direct audio
output, the output level of 600W line an direct audio are adjustable via VR601 on the
front panel.
U604 is the power amplifier for internal and external speaker, the power level can be
adjusted by VR602 on the front panel.
Depending on the squelch, RL602 will apply a 12VDC to the 600W line output when
loop function is selected. If the loop function is not used, RL602 always stay in the
position of which C619 is bypassed. The position of RL602 is controlled by the signal
LOOP/VOLTS_SEL from the MicroController U204.
Opto-coupled transistor Switch U601 provides a COS (Carrier Operated Switch)
output which is controlled by COS_POLARITY signal from the MicroController. The
output COS+ and COS- can be used as +12V DC source or a free switch depending on
the status of the relay RL601, RL601 is controlled by COS_VOLTS_ON/OFF signal
from the MicroController U204.
Discriminated audio level is detected by D604 and C623, signal LINE_LEVEL is
connected to the analog-digital converter input pin of the MicroController for
calibration purpose.
5.7 Power Generation Section (Sheet 7)
There are three switch-mode dc-dc converters in the board. These use monolithic
converters based on the National LM2595. Two of the converters are 12V converters
and one is a 5V converter.
The power in to the whole exciter is the voltage rail 28V.
U907 converts this down to 12V.
U908 is set up as an inverter, and uses the 12V rail to create -12V.
U909 converts the +12V rail to +5V for all the digital circuitry.
The +12V rail is used to power the two on-board relays, as well as up to one extra offboard relay. It is also dropped, via a linear regulator (U910) to produce the +10V rail,
which in turn is dropped by another linear regulator U911 to produce +5Q.
Similarly U913 and U914 are linear regulators that produce -10V and -5V from the 12V output of U908.
+2.5Vand -2.5V are not used in the R50 receiver, the reason of being showed on the
schematic diagram is to keep same design of the T50 power generation section.

6 FIELD ALIGNMENT (CALIBRATION) PROCEDURE
D911 is a 4.096V (3%) reference diode. Its output is buffered by U906 which then
produces a reference voltage rail Vref, which is used by the CPU's A/D converter, and
the DACs.
Field Alignment (Calibration) Procedure
6.1 Standard Test Equipment
Some, or all of the following equipment will be required:
Power supply set to 28Vdc, with current >1A.
RF Signal Generator
50 Ohm Output impedance
Frequency range 25-50MHz
FM modulation at 1KHz
3KHz peak deviation for 25KHz or 20KHz channel spacing
Frequency Counter
The accuracy should be at least 0.5ppm, preferably 0.1ppm
True RMS AC voltmeter, and a DC voltmeter.
6.2 Invoking the Calibration Procedure
The R50 has in-built firmware to perform calibration. This firmware requests the user
for information as to meter readings, and/or to attach or adjust the AF signal generator.
The firmware based calibration program can be accessed from a terminal, a terminal
emulator, or the Eclipse50 terminal emulator.
As for Section 4.1, the firmware, after power up, issues the following prompt:
R50>
Via a terminal, or a terminal emulator, a user can type various commands in. The basic
command to start the calibration procedure is:
R50> cal calibration_type
Where "calibration_type" is one of:
(a) misc:
(b) line:
(c) ref:
(d) all :
Miscellaneous parameters are defined and calibrated
Line1, Line2, Dir Aud (Tone), and microphone inputs are tested and
calibrated.
The reference oscillators are adjusted and calibrated
(which does all the above)
Page 18
RF Technology R50
6 FIELD ALIGNMENT (CALIBRATION) PROCEDURE
6.3 The "Miscellaneous" Calibration Procedure
R50> cal misc
This procedure should not normally be invoked as part of any field maintenance.
The program will print out the Model Name and Serial Number of the exciter. If these
parameters haven't already been defined (e.g. at an initial calibration, at the factory,
the service personnel will be prompted to enter these values).
Then it will ask the operator to enter the value of Vref (as measured at TP913, see
5.7).
Measure the voltage, at TP913 (Vref)
and type it on the command line...
Unless the reference diode D911 has been replaced, this should not be done. The user
should simply hit the Enter key to bypass this operation. If, though, D911 has been
replaced for some reason, then, the lid of the unit should be removed, and the voltage
measured. TP913 can be found just above JP12 (near the centre of the exciter).
Then the receiver low battery alarm level will be asked for. If the current value is
acceptable, the User need only hit the Enter key on the keyboard. If another value is
preferred, then that value can be typed in.
For example:
The Exciter's Low Battery Alarm is 24V
If this is correct enter ,
else enter the new value: 26
In this example, the low Battery Alarm level is changed to 26V.
Then the user will be prompted for serial port baud rates, parities etc. Please leave
these parameters unchanged unless you are familiar with how to change such
parameters on your PC. The Eclipse50 software will expect 57600 BPS, and No
Parity, and No Flow Control. Note well, that if you do change any of these, the
change will not take effect until you power down the receiver and then power it up
again. (As an alternative to power cycling the receiver, and if the cover is off the
receiver, you may simply press switch momentary push-button S200 (see 5.2).
Then the following questions are:
Is Flat frequency response on by default (Y/N)?
Is COS purely a sink of current (Y/N)?
Is COS Asserted when the Squelch is closed (Y/N)?
Is COS UnAsserted when the Squelch is open (Y/N)?
Is LOOP Asserted when the Squelch is closed (Y/N)?
Is LOOP UnAsserted when the Squelch is open (Y/N)?
Always hit "Enter key" unless the value other than default is required, note use the "Y"
key if default value need to be changed.

6.4 Line Calibration Procedure
R50> cal line
This procedure is used for calibrating the RF RSSI level reading, FM modulation
(deviation) reading. Also this procedure is used to set the 600 Ohm audio line output
level, Noise squelch level and Carrier squelch level. Simply follow the instruction of
the software as bellow:
Attach an RF signal generator to the input.
Set the RF output to 37.5MHz,
and an input level of -110dBm
with a 1kHz tone and 3kHz deviation.
Adjust the Volume Pot until the DIR AUD output
is 388mV.(eqvt to 0dBm into 600 ohms)
Enter  when done.
Set the RF signal generator's output to -60dBm
Enter  when done.
rssi_scale is 0.417dBm/dac step, and rssi offset is -137.500dBm) --- for example
Adjust the Modulation to only 1KHz max deviation
Enter  when done.
deviation_scale is 1.000dBm/dac step, and
deviation offset is .000dBm
--- for example
Adjust the Carrier Squelch to the desired level
Enter  when set.
-99.5
--- for example
Enter the Fast Noise Threshold(in dBm):
Enter the Carrier Alarm Threshold(in dBm):
Set the RF generator output to the desired level ( < -105dBm ),
and adjust the N.SQ adjustment counter clockwise
until the squelch opens, thence turn it clockwise
until the noise is muted.
Enter  when done
6.5 The "Reference" Calibration Procedure
R50> cal ref
To compensate for crystal ageing and other parameters that drift, the following
procedure should be performed approximately once per year.
Open the cover of the receiver, find out the test point TP209 on receiver PCB, using a
frequency counter to measure the frequency and follow the instruction as bellow:
