SERVICE MEASUREMENT

2 - 2

Tuner FW

RF Generator

e.g. PM5326

DUT

Bandpass

250Hz-15kHz

e.g. 7122 707 48001

LF Voltmeter

e.g. PM2534

Ri=50

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).

Tuner AM (MW,LW)

RF Generator

e.g. PM5326

Ri=50

DUT

Frame aerial

e.g. 7122 707 89001

Bandpass

250Hz-15kHz

e.g. 7122 707 48001

LF Voltmeter

e.g. PM2534

S/N and distortion meter

e.g. Sound Technology ST1700B

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).

CD RECORDER

Use Audio Signal Disc SBC429 4822 397 30184 (replaces test disc 3)

DUT

S/N and distortion meter

e.g. Sound Technology ST1700B

LEVEL METER

e.g. Sennheiser UPM550

with FF-filter

Use Universal Test Cassette Fe SBC420 4822 397 30071

LF Generator

e.g. PM5110

DUT

Ri=50

S/N and distortion meter

e.g. Sound Technology ST1700B

LEVEL METER

e.g. Sennheiser UPM550

with FF-filter
