8. Enter the value measured by multimeter (Step 4) using SCPI command.
9. Calculate the crossover point at 100 kHz by using below formula.
Crossover @100 kHz = Power meter converted value in Vrms (Step 7) – Multimeter measured value in Vrms
(Step 4)
10. Using the existing connection, configure the instrument and measure the output for each setup in the following
table.
Setup Frequency
48 1 MHz
49 5 MHz
50 10 MHz
51 20 MHz
52 25 MHz
53 30 MHz
[a] Constants are stored after completing this setup.
11. Convert the measured power level from dBm to Vrms.
12. Enter the value measured (calibration value) using SCPI command.
Calibration Value = Power meter converted value in Vrms – Crossover @100 kHz in Vrms (Step 9)
13. To proceed:
a. If your calibration procedures require you to verify this adjustment, exit the calibration menu and perform
dB range flatness
b. If you are making all of the adjustments and then verifying the instrument's performance, verify the output
specifications of the instrument with the
This completes the adjustment procedures for the one-channel instrument. Verification of the output specifications
is recommended.
If you are making adjustment to a two-channel instrument, continue with the next procedure in this section
