Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz). RF Generator e.g. PM5326 Ri=50: Bandpass 250Hz-15kHz e.g. 7122 707 48001 LF Voltmeter e.g. PM2534 DUT RF Generator e.g. PM5326 S/N and distortion meter e.g. Sound Technology ST1700B Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz).
