3. Selectivity:
Using the AGC voltage produced by a -103 dBm standard signal reference, mea-
sure and record the frequencies which reproduce the AGC REF voltage at 6 dB
and 60 dB above the reference input. To measure the relative AGC voltage it is
necessary to provide a 100 kΩ pullup resistor from P155A1 pin J to +15 VDC.
4. Volume Gain Control: Min _________ 20mV Max. ________ NLT 7.07V across 500
ohm
5. Audio Distortion: 350 Hz = _________ (15% Max) 1 kHz = _______ (15% Max)
2.5 kHz = _____ (15% Max)
Input a -73 dBm 85% modulated signal between 350 Hz and 2500 Hz. (This is an
optional test that requires a distortion analyzer)
6. Audio Response: 350 Hz = ______ NMT 6dB down 1 kHz = 0 dB
2.5 kHz = _____ NMT 6 dB down.
Input a standard -73 dBm signal into the unit. Disable the compressor. (See com-
pressor disable in
quency is varied.
