To avoid multiple waveform changes, enable modulation after configuring the other modulation parameters.
SCPI Command
[SOURce[1|2]:]PM:STATe {ON|1|OFF|0}
Carrier Waveform Shape
PM carrier shape: Sine (default), Square, Ramp, Triangle, Pulse, PRBS, or Arbitrary. You cannot use Noise or DC as
the carrier waveform.
Front Panel Operation
Press [Waveform]. Then select any waveform except Noise or DC.
SCPI Command
[SOURce[1|2]:]FUNCtion <function>
– The APPLy command configures a waveform with one command.
– When the carrier is an arbitrary waveform, modulation affects the sample "clock" instead of the full cycle defined
by the arbitrary waveform sample set. Because of this, applying phase modulation to arbitrary waveforms is limited.
Carrier Frequency
The maximum carrier frequency varies by function, model, and output voltage, as shown here. The default is 1 kHz
for all functions other than arbitrary waveforms. Carrier frequency must be greater than 20 times the peak
modulation frequency.
Front Panel Operation
Press AM Freq or FM Freq or any other Frequency key. Use the numeric keypad or the knob and arrows to set a
desired value. If you use the keypad, select a prefix unit to finish.
SCPI Command
[SOURce[1|2]:]FREQuency {<frequency>|MINimum|MAXimum|DEFault}
The APPLy command configures a waveform with one command.
Modulating Waveform Shape
The modulating waveform shape may be:
– Sine wave
– Square with 50% duty cycle
– Triangle with 50% symmetry
– UpRamp with 100% symmetry
