1. Input SG11 into VIF IN, and measure EQ output TP22A with an oscilloscope.
voltage of AFT output TP2 is 3V . This frequency is named f(3).
This frequency is named f(2)
respectively.
The inter modulation is defined as a difference between 0.92MHz and
3.58 MHz frequency components.
output waveform is 1.0V.
