Procedure
Part 1 Source Module Calibration
1. On the RF power meter, perform ZERO and calibration with the RF power sen-
sor.
2. Connect equipment as shown in Figure 6-5. (Use the RF power sensor Q8486A)
3. On the SG, set controls as follows;
Output Frequency: 40.0 GHz
Output Level: 0 dBm
4. On the RF power meter set correction data for 40.0 GHz.
5. Measure the source module output level, and then record it in reference column
on the performance verification test record sheets.
6. On the SG, set control as follow;
Output Frequency: 40.1 GHz
7. On the RF power meter set correction data for 40.1 GHz.
8. Measure the source module output level, and then record it in reference column
on the performance verification test record sheets.
9. Repeat steps 6 through 8 for the SG output frequency and RF power meter cor-
rection data up to 50 GHz by 100 MHz steps.
10. Change the RF power sensor to V8486A.
11. On the SG, set control as follow;
Output Frequency: 50.1 GHz
