Output Power Adjustment

This adjustment applies to the following models:

M9380A
M9381A
M9389A

There are four power adjustments, one for each RF output port (1A/B and 2A/B) on the M9380A and M9381A, and one on the M9389A RF/LO output port. In this process, a separate measurement is made at each RF output using a power meter, and based on the result a computer algorithm calculates the value to adjust the output step attenuator.
