SIF Block (FM block) Input Signals and Test Conditions
Unless otherwise specified, the following conditions apply when each measurement is made.
1. Bus control condition:
IF.AGC.SW = "1", SIF.SYS = "01", DEEM-TC = "0", FM.GAIN = "0", A.MONI.SW = "0", A2.SW = "0"
2. SW:IF1 = "ON", 24pin = 5V
3. Input signals are input to pin 54 and the carrier frequency is 5.5MHz.
