11. Inter modulation: IM
1. Input SG11 into VIF IN, and measure EQ output TP22A with an oscilloscope.
2. Adjust AGC filter voltage V10 so that the minimum DC level of the
output waveform is 1.0V.
3. At this time, measure TP22A with a spectrum analyzer .
The inter modulation is defined as a difference between 0.92MHz and
3.58 MHz frequency components.
10. AFT sensitivity u, Maximum AFT voltage V
2H
, Minimum AFT voltage V
2L
1. Input SG10 into VIF IN, and set the frequency of SG10 so that the
voltage of AFT output TP2 is 3V . This frequency is named f(3).
2. Set the frequency of SG10 so that the AFT output voltage is 2V.
This frequency is named f(2)
