Temperature Adjustment and Test of the YIG Filter
A digital temperature adjustment is to be performed for the following MW converters:
- MW converter unit 13/30: 1093.8249 Mod: XX Rev: 10 SubRev: 01
- All other MW converters should undergo analog adjustment.
Analog adjustment:
- 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 FSP30: 200 MHz
- Set the frequency of the signal generator and the center frequency to 15 GHz.
Nominal value: Temperature drift (0 to 50°C) < 8 MHz
- Adjust temperature drift with jumpers X21, X22, X23, trimming values R403, R119, R402 and
potentiometer R232.
Digital adjustment:
- Place R&S FSP30 into a climatic chamber for 2 hours at 50°C.
- Execute frequency response correction 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 FSP30 into a climatic chamber for 2 hours at 0°C in the switched-off state.
- Switch on the instrument and repeat the coldness adjustment.
