Dimension (W x H x D) : 294 x 145 x 245 mm Weight : 2.4 Kg TUNER - FM SECTION Tuning range IF frequency Sensitivity Selectivity IF rejection Image rejection Crosstalk : MHz : 10.7 MHz ± 0.2 MHz : 20 dbf at 26dB S/N : 30 db at 300kHz : 50 db : 20 db : 20 db AMPLIFIER Output power Speaker impedance Frequency response COMPACT DISC mains : 2 x 1 W battery : 2 x 1 W : 2 x 8 ohm : 100 Hz - 10 khz (±3dB) TUNER - AM SECTION Tuning range IF frequency Sensitivity Selectivity IF rejection Image rejection MW : khz : 450 khz ± 1 khz MW : 4500 µv/m at 26dB S/N MW : 16 db MW : 60 db MW : 28 db Frequency response : 100 Hz - 10 khz ± 2dB S/N ratio : 60 db Channel difference 1 khz : 2 db Channel crosstalk 1 khz : 40 db Laser wavelength : 780 ± 20 nm Laser light power : < 0.5 mw

4 2-2 SERVICE MEASUREMENT Tuner SW RF Generator e.g. PM5326 Aerial replacement Capacitor DUT Bandpass 250Hz-15kHz e.g LF Voltmeter e.g. PM2534 Ri=50Ω R=50Ω 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 250Hz) to eliminate hum (50Hz, 100Hz). Tuner AM (MW,LW) DUT Bandpass 250Hz-15kHz e.g LF Voltmeter e.g. PM2534 RF Generator e.g. PM5326 Ri=50Ω Frame aerial e.g 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. CD Use Audio Signal Disc SBC (replaces test disc 3) L.P.F. = 13 th order filter DUT L Low pass filter 22kHz R S/N and distortion meter e.g. Sound Technology ST1700B LEVEL METER e.g. Sennheiser UPM550 with FF-filter
