Description The HP Model 11793A Microwave Converter down-converts microwave input signals in the range from 1.3 to 26.5 GHz. For frequencies below 1.3 GHz, signals are routed directly to the input of the measuring instrument. Instruments suitable for lower frequency measuring are the HP 890 1B Modulation Analyzer or the HP 8902A Measuring Receiver. For input signals above 1.3 GHz, the Microwave Converter routes the signal through an internal mixer which mixes the input signal with an external local oscillator. The difference frequency (that is, the intermediate frequency or IF) is filtered, amplified, and then appears a t the IF OUTPUT connector. The IF should be between 10 and 700 MHz. The Microwave Converter requires a +8 dBm leveled output from the LO. For LOs with insufficient power above 18 GHz, an optional internal amplifier ( 1 8 GHz to 26.5 GHz) is available. The measuring instrument controls switching of the RF path and of the LO amplifier via a rear-panel connection on the Microwave Converter. 2 Model 11793A 6. Microwave Converter Options and Accessories Electrical Options The options are summarized in Table 3. The following list describes each option: Option 001.

The measuring instrument must be in frequency offset mode in order to enter the RF Power calibration factors into the Frequency Offset mode RF Power Cal Factor Table. 2. Set the microwave LO source frequency and level as listed in Table 6. Performance Tests Znstrument Settings. For each setting, perform the following steps: a. Set the frequency of the microwave signal source as listed. b. On the measuring instrument, key in 27.3 SPCL. Key in the frequency of the microwave LO source (in MHz), then press the MHz key. c. On the measuring instrument, measure RF frequency and R F Power (in that order). The measuring instrument's display should read as indicated in table 6. (The listed frequency is a nominal value.) 3. Set the RF signal source to 1270 MHz. and level - 10 dBm. 4. On the measuring instrument, key in 27.3 SPCL and enter 0 MHz. This leaves the measuring instrument in frequency offset mode with 0 MHz offset. Measure RF Frequency and RF Power (in that order). 12 Model 11793A Microwave Converter Table 6.

Address the order to the nearest Hewlett -Packard office. 31. Manual Changes These paragraphs contain manual change instructions for backdating this manual for HP Model Microwave Converters with the serial number prefix 2407A. 1793A Instruments with Serial Prefix 2407A have System I1 cabinet parts and hardware that are English thread. Instruments with Serial Prefix 2520A and higher have System I1 cabinet parts and hardware that are METRIC thread. In Table 7 . Replaceable P U Y ~ Sboth , English and Metric thread part numbers are listed for the System I1 cabinet parts. These correct part numbers are referenced under the instrument’s serial number prefix. Instruments with the serial number prefix 2407A have MP3 (rear frame), MP8 (rear panel), and associated english thread hardware, that are screwed together. These parts have been changed to a riveted, one piece assembly that is referenced to MP8. To replace MP8 you must order the Rear Panel Assembly 1 1793-20009, and the metric screws for the side struts and rear feet. 32. SERVICE 33. Principles of Operation Simplified Block Diagram A simplified block diagram of the Microwave Converter is shown in Figure 10. The signal a t the RF INPUT connector is routed through an input switch either to the Direct Path (and out the IF OUTPUT connector), or to the Down-Convert Path. The Down-Convert Path has a 3 dB RF Attenuator (to improve input SWR), a Mixer (tte down-converter), an IF Low-pass Filter (to remove the sum component of the mixing process while passing the difference component), and a + 1 S dB IF Amplifier (to restore signal loss through the Down-Convert Path). Usually, the LO frequency selected is higher than the frequency of the input signal. (The measuring instrument assumes this.) The difference frequency (the IF) is filtered by the IF Low-Pass Filter, which has a 3 dB corner of 800 MHz. The IF should be kept between the range of 10 and 700 MHz. If the instrument has the optional LO Amplifier installed, the measuring instrument automatically switches in the amplifier whenever an LO frequency greater than 18 GHz is selected. 23 Model 1 1793A Microwave Converter Service Sheets 1 and 2 (Input Signal Down-Converter) A single input on the rear panel: the FREQ OFFSET INPUT, has three logic states which control both the switching of the RF two paths, and the insertion of the optional LO Amplifier. The Level Comparator senses the three states and drives the appropriate switches. Service Sheets 1 and 2 are the schematic diagrams of the RF circuitry of the Microwave Converter. Service Sheet 1 (SS1) documents the standard Microwave Converter (without the LO Amplifier option), and Service Sheet 2 (SS2) documents the Microwave Converter with the LO Amplifier. The operation of the R F components is discussed in the principles of operation for the Simplified Block Diagram above. Note that the RF switches (SI and S2), shown in the schematic, automatically interrupt the current flowing into the energized solenoid once the plunger switches the RF contacts. The plungers latch via permanent magnets. Service Sheet 3 (AI Switch Control Assembly) The Level Comparator ( U I A and U1B) and Decoder (U3A, U3B, and U3C) decode a three level input (through the rear-panel FREQ OFFSET INPUT connector) into binary levels that control the RF switches (see SS1 and SS2). The AND gates (U2) are simply open-collector inverters,'which drive the transistors (42, 43, 4 4 , QS) to switch on and energize the solenoids of the RF switches. Table 9 summarizes the decoding.

It is the current input to the +SV Regulator as well as the reference from which both the Level comparator references are derived, and the RF Amplifiers are powered. e The regulated +SV supplies current to most logic devices. Either the +26 or +12V supply can trigger the Over-Voltage Protection should the respective voltage exceed +42 or + 12V. LED DS 1 gives an indication that the supply is nominally operational. 24 Model 11793A Microwave Converter 34.

Such maintenance should be performed only by service-trained personnel who are aware o f the hazards involved. Use the correct torque wrench when installing sub -miniature connectors. Do not exceed the following torque settings for this instrument: 1.5 N.m for the 3 mm (TlO) screws 2.0 N.m f o r the 4 mm (T15) screws 0.7 N.m (6.3 in.lb) for S M A connectors 0.7 N’m (6.3 in.lb) for Type-N connectors General Troubleshooting information is broken down into three categories: 0 RF devices, control devices, and 0 power supplies. Either a compatible measuring instrument or a power supply connected to the FREQ OFFSET INPUT, can be used to control the RF switches. If a power supply is used, set it to 0, +3, or + S Vdc as dictated by Table 9. 2s Model 1 1793A Microwave Converter RF Devices (Service Sheets 1 and 2) Because of the diversity of test equipment and techniques available for troubleshooting the high-frequency devices, no specific procedures are given. Check the performance parameters of the RF devices against the following table, Table 10. Also check connectors and cables. Table 10.
