Analysis the Modulated Signals
5 Press Shift > Disp > Y Scale > Scale Coupling On to set the Y
scale auto coupling.
6 Set the FM deviation limit and turn on the limit function:
Press Shift > Limits > FreqDev UP > 11 > % > FreqDev Low > 9.9
> % > Limits on
The red value in the result indicates the demodulated FM
deviation exceeds the limits set as above.
