SERVICE MEASUREMENT 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 Tuner FW Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz). Ri=50½ Bandpass 250Hz-15kHz e.g. 7122 707 48001 LF Voltmeter e.g. PM2534 DUT S/N and distortion meter e.g. Sound Technology ST1700B Frame aerial e.g. 7122 707 89001 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). RF Generator e.g. PM5326 Ri=50½ L R LEVEL METER e.g. Sennheiser UPM550 with FF-filter S/N and distortion meter e.g. Sound Technology ST1700B DUT CD RECORDER Use Audio Signal Disc SBC429 4822 397 30184 (replaces test disc 3) Use Universal Test Cassette Fe SBC420 4822 397 30071 L R LEVEL METER e.g. Sennheiser UPM550 with FF-filter S/N and distortion meter e.g. Sound Technology ST1700B DUT LF Generator e.g. PM5110 Ri=50½
