Frequency Modulation (FM)

Modulating Waveform Frequency
The waveform generator will accept an internal or external modulation
source for FM.
• Modulating frequency (internal source): 1 Hz to 30 MHz.
The default is 10 Hz .
• Front-Panel Operation : After selecting FM, press the FM Freq softkey.
•
Remote Interface Operation :
[SOURce[1|2]:] FM:INTernal:FREQuency
{<

Frequency Deviation
The frequency deviation setting represents the peak variation in
frequency of the modulated waveform from the carrier frequency.
• Frequency deviation: 1 Hz to (carrier frequency)/2
. 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 waveform 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
(30.1 MHz for sine and square and 300 kHz for ramp). If you attempt
to set the deviation to a value that is not valid, the waveform
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}
