11. Inter modulation: IM
1. Input SG11 into VIF IN, and measure video output TP9 with an oscilloscope.
2. Adjust AGC filter voltage V23 so that the minimum DC level of the output
waveform is 1.0V.
3. At this time, measure TP9 with a spectrum analyzer .
The inter modulation is defined as a difference between 0.92MHz and
3.58 MHz frequency components.
10. AFT sensitivity μ, Maximum AFT voltage V
18H
, Minimum AFT voltage V
18L
1. Input SG10 into VIF IN , and set the frequency of SG10 so that the voltage
of AFT output TP18 is 3[V] . This frequency is named f(3).
2. Set the frequency of SG10 so that the AFT output voltage is 2[V].
This frequency is named f(2)
3. IN the graph, maximum and minimum DC voltage are V
18H
and V
18L
,
respectively.
