equal to the peak deviation frequency. The sum of
the deviation and carrier frequency must not
exceed the maximum frequency for a specific
carrier shape. If an out of range deviation is set for
any of the above conditions, the deviation will be
automatically adjusted to the maximum value
allowed and an “out of range” error will be
generated.
For square wave carrier waveforms, the deviation
may cause the duty cycle frequency boundary to
be exceeded. In these conditions the duty cycle will
be adjusted to the maximum allowed and a
“settings conflict” error will be generated.
Syntax SOURce[1|2]:FM:DEViation {<peak deviation in
Hz>|MINimum|MAXimum}
