6.2.1.2 Frequency Response
Description:
Verify the external mixer frequency response against specification.
Firstly measure the source module out power with RF power meter and RF power sensor in the entire
frequency range by 100 MHz step, and record it as calibrated value.
Use two type power sensor depending frequency range, one is Q8486A for 40 GHz to 50 GHz. The
other is V8486A for 50 GHz to 60 GHz.
Secondary connect external mixer to the source module, and then measure the frequency response on
the R3172/R3182 screen in the entire frequency range by 100 MHz step, and record it as measured
value.
Calculate between the calibrated value and measured value for the frequency response.
