6.3.1.2 Frequency Response
Description:
Verify the external mixer frequency response against specification both frequency range of 50 GHz
to 75 GHz and 70 GHz to 80 GHz.
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.
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.
