Phase Modulation (PM)
3
Modulating Waveform Frequency
The waveform generator will accept an internal or external modulation
source for PM. The external modulation input has a -3dB bandwidth of
100 kHz.
• Modulating frequency (internal source): 1 Hz to 30 MHz.
The default
is 10 Hz
.
•
Front-Panel Operation
: After enabling PM, press the
PM Freq
softkey.
•
Remote Interface Operation
:
[SOURce[1|2]:]
PM:INTernal:FREQuency

Phase Deviation
The phase deviation setting represents the peak variation in phase of the
modulated waveform from the carrier waveform. The phase deviation
can be set from 0 to 360 degrees. The default is 180 degrees.
•
Front-Panel Operation
: After enabling PM, press
Phase Dev
. Then use
the knob or numeric keypad to enter the desired deviation.
• Remote Interface Operation:
PM:DEViation {<deviation_in_degrees>|MINimum|MAXimum}
