Audio Block Input Signals and Test Conditions
Unless otherwise specified, the following conditions apply when each measurement is made.
1. Bus control condition:
AUDIO.MUTE = "0", A.MONI.SW = "0", AUDIO.SW = "1", VOL.FIL = "0", SIF.SYS = "01", IF.AGC.SW = "1"
2. Input 5.5MHz, 90dB
and CW at pin 54.
3. Enter an input signal from pin 51.
