Replacing Diplexer A163; R&S FSP40
(See chapter 5, spare parts list, item 2225, and drawing 1093.8584.)
The board is installed on the 40 GHz converter unit (141).
Removing the Diplexers on the 40 GHz MW Converter
Remove 8 GHz converter unit (130).
Note: See description "Replacing MW Converter Unit A160".
Disconnect cable W5 from diplexer (2225).
Undo 4 screws with washers (2230) from the bottom side of the PCB.

Note: The diplexer is connected to the PCB with contact pins.
Refasten 4 screws with washers (2230) to the bottom side of the PCB.
Connect cable W5 to diplexer (2225)
Completing the Instrument and Frequency Response Correction
Put the 40 GHz MW converter unit (141) 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.
Create a backup of the EEPROM data (see chapter 2, section "Adjustment of Module Data").
