Module Replacement R&S FSP
1164.4556.82 3.42 E-1
Completing the Instrument and Frequency Response Correction
Put 8 GHz converter unit (130) back into the instrument.
Note: See description "Replacing MW Converter Unit A160".
Execute frequency response correction software R&S FSP-FRQ.EXE.
The software is located on the Gloris server.
- Test setup according to menu item "Schematic" (connect external reference).
- Check IEC/IEEE addresses and configuration of instruments.
- Press the Autoselect button and perform the measurement with Run.
- The frequency correction of the YIG filter is performed under item YIG.
- After calibration, the frequency response is corrected over the entire frequency range.
Temperature Adjustment and Test of the YIG Filter
A digital temperature adjustment is to be performed for the following MW converters:
- MW converter unit 8: 1130.2544 Mod: XX Rev: 05 Subrev: 01
- All other MW converters should undergo analog adjustment.
Analog adjustment for converter unit 1130.2396 and for converter unit 1130.2544 with HWC = 00:
- Connect the RF output of the signal generator to the RF input of the R&S FSP
- Activate the YIG filter sweep with the service function:
Password 30473035
Service funct. 2.16.10.1
- Span on R&S FSP7: 200 MHz
- Set the signal generator frequency an the center frequency to 5 GHz
Nominal value: Temperature drift (0 to 50 C) < 8 MHz
- If X21 is used for temperature compensation, the temperature drift can be adapted via trimming
resistor R232 or trimming value R374.
Digital adjustment:
- Place R&S FSP7 into a climatic chamber for 2 hours at 50°C.
- Execute frequency response correction software R&S FSP-FRQ.EXE.
The software is located on the Gloris server.
- Test setup according to menu item "Schematic" (connect external reference)
- Check IEC/IEEE addresses and configuration of instruments.
- Press the TK adjustment button.
- Place R&S FSP7 into a climatic chamber for 2 hours at 0°C in the switched-off state.
- Switch on the instrument and repeat the coldness adjustment
Adjustment of Module Data
Create a backup of the EEPROM data (see chapter 2, section "Adjustment of Module Data").
