Note 1: Measure the circuit current when no signal is present.
Note 2: Apply a sine wave of f = 1kHz to the input, and adjust the input
level so that the output distortion is 1%. At this time, set the out-
put voltage to the maximum output level of VOM [VP-P].
Note 3: Measure the output VO [VP-P] with a sine wave of f = 4.43MHz,
1VP-P applied to the input. Voltage gain GV is:
GV = 20 Log (VO / VIN) [dB]
Note 4: Measure the outputs VO7 and VO1 [VP-P] each with sine waves of
f = 7MHz, 1VP-P and f = 1MHz, 1VP-P applied to the input. Voltage
frequency GF is:
GF = 20 Log (VO7 / VO1) [dB]
Note 5: Measure the output VO [VP-P] with a sine wave of f = 4.43MHz,
1VP-P applied to the input. Interchannel crosstalk CT is:
CT = 20 Log (VO / VIN) [dB]
Note 6: Measure the output VO [VP-P] with a sine wave of f = 4.43MHz,
1VP-P applied to the input. The muting attenuation MT is:
MT = 20 ∗ Log (VO / VIN) [dB]
