Peak Frequency Deviation

The peak frequency deviation represents the variation in frequency of the
modulating waveform from the carrier frequency.
• Peak frequency deviation: 5 Hz to 40.05 MHz (limited to 550 kHz for
ramps and 12.55 MHz for arbitrary waveforms). The default is 100 Hz.
• The carrier frequency must always be greater than or equal to the
deviation. If you attempt to set the deviation to a value greater than
the carrier frequency (with FM enabled), the function generator will
limit the deviation to the maximum value allowed with the present
carrier frequency.
• The sum of the carrier frequency and deviation must be less than or
equal to the maximum frequency for the selected function plus 100 kHz
(80.1 MHz for sine and square, 1.1 MHz for ramp, and 25.1 MHz for
arbitrary waveforms). If you attempt to set the deviation to a value
that is not valid, the function generator will limit it to the maximum
value allowed with the present carrier frequency.
• Front-Panel Operation: After enabling FM, press the Freq Dev softkey.
Then use the knob or numeric keypad to enter the desired deviation.
• Remote Interface Operation:
FM:DEViation {<peak deviation in Hz>|MINimum|MAXimum}
