FM:INTernal:FUNCtion?
Query the modulating function used in frequency modulation. “SIN”, “SQU”,
“RAMP”, “NRAM”, “TRI”, “NOIS” or ”USER” string indicating the modulating
function will be returned.
-- Square waveform has 50% duty cycle.
--Ramp waveform has 100% symmetry
--Triangle waveform has 50% symmetry.
--Negative Ramp waveform has 0% symmetry.
--If an Arbitrary(USER) waveform is chosen to be the modulating waveform, it is
automatically limited to 4k points. Extra points are removed using decimation.
FM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
Specify the frequency of the modulating waveform. This applies only when the
modulating source is internal. The range is from 2 mHz to 20 kHz and the default
is 10 Hz.
FM:INTernal:FREQuency? [MINimum|MAXimum]
Query the modulating frequency in frequency modulation. The modulating
waveform frequency in hertz will be returned.
FM:DEViation {<peak deviation in hertz>|MINimum|MAXimum}
Specify the peak frequency deviation in hertz. This value represents the peak
variation in frequency of the modulated waveform from the carrier frequency.
The range is from 1µHz to 150 kHz for ramps, from 1µHz to 5.05 MHz for
arbitrary waveforms, from 1µHz to 12.55 MHz for square waveforms and from
1µHz to 25.05 MHz for sine waveforms and the default is 100 Hz. The minimum
value is 1 µHz, but the maximum value is calculated based on the frequency of
the carrier waveform as below:
Maximum deviation = carrier frequency
if the carrier frequency is less than Maximum frequency/2
Maximum deviation = Maximum frequency – carrier frequency
if the carrier frequency is greater than Maximum frequency/2
The frequency deviation must not be greater than the carrier frequency. If a
greater value is set to be the deviation, G5100 waveform generator will adjust it
