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
Tuner FW
Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz).

Tuner AM (MW,LW)
To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday«s cage.
Use a bandpass filter (or at least a high pass filter with 250kHz) to eliminate hum (50Hz, 100Hz).
