Measurement setup CD Use Audio Signal disc SBC429 4822 397 30184 Measurement setup FM Use bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from pilottone (19kHz, 38kHz). Measurement setup AM To avoid admospheric interference all AM measurements have to be carried out in a Farradays cage. Use bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz). 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 aeriale.g. 7122 707 89001 RF Generator e.g. PM5326 Ri=50Ω 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 Ri=50Ω Low pass filter DUT S/N and distortion meter L R i.e. Sennheiser UPM550 with FF-filter Level meter i.e. Sound Technology ST1700B i.e. 4822 395 3020422kHz 13th order 1-2 CS 46 743 FEATURE OVERVIEW E L B A T R O P - D C F O S E R U T A E F R E N U T - A R T L U Y L I M A F T C U D O R P 0 4 2 9 T Z A) s n o i s r e v l l a ( W S / W M / M F R E N U T ●/●– / Y T I L I B I T A P M O C E L B A T I R W E R - D C ● N O I T C E T O R P P I K S C I N O R T C E L Es 5 4 E Z I S M A R D P S Et i b M 6 1 N O I T C N U F E M U S E R / D L O H ●/● S E G A T S B B D2 K C A B D E E F C I T S U O C A ● Y R O M E M M A R G O R P9 9 H M i N / d C i N N O I T C N U F E G R A H C E R ●/● D E R A P E R P L O R T N O C E T O M E R D R O C– T H G I L K C A B Y A L P S I D– T U P T U O L A T I G I D / E N I L– / –
