Test Description

To test second harmonic distortion, a 50 MHz low pass filter is used to filter the source

output, ensuring that harmonics read by the analyzer are internally generated and not

coming from the source. The source power and input attenuation on the analyzer are

adjusted so –20 dBm is the power level at the first mixer.
