5 Press Shift > Disp > Y Scale > Scale Coupling On to set the Y
scale auto coupling.
6 Set the AM depth limit and turn on the limit function:
Press Shift > Limit > AM Depth UP > 51 > % > AM Depth Low > 49
> % > Limits on
The red value in the result indicates the demodulated AM
depth exceeds the limits set as above.

FM Modulation Analysis
Please refer to the procedures below for the FM modulation
analysis:
1 Connect the signal generator to RF IN connector and turn
on the signal generator's FM and RF output.
2 Turn on the FM demodulation analysis function.
Press MODE > Modulation Analysis > AM.
3 Press Frequency > Carrier Freq > 100 > MHz to set the carrier
frequency.
4 Set the attenuation state to Auto (default):
Press Amplitude > Attenuation Auto
