Phase Deviation

The phase deviation setting represents the peak variation in
phase of the modulated waveform from the carrier
waveform. The phase deviation setting can be set from
0 to 360

°. The default phase deviation setting is 180°.

Soft Front Panel Operation

On the Phase Deviation panel as shown in

Figure 2- 20

,

input the desired phase deviation value.

Remote Interface Operation

PM:DEViation <deviation in degrees>

Generate PM Using SCPI Commands

Example 1

-> *CLS

; *RST

//To reset the U2761A to default

power

-on state, this command

can be ignored if this operation
is not required.

-> PM:STAT ON

//Enables PM.

-> FUNC SIN

//Sets the carrier waveform to

Sine wave.

-> FREQ 1000

//Sets the carrier frequency to

1 kHz.

-> VOLT 5 VPP

//Sets the output amplitude to

5 Vpp.

-> VOLT:OFFS 0

//Sets the output offset to 0.

-> PM:INT:FUNC SIN

//Changes the modulating

waveform shape to Sine wave.

-> PM:INT:FREQ 500

//Changes the modulating

frequency to 500 Hz.

-> PM:DEV 180

//Changes the phase deviation to

180

°.

-> OUTP ON

//Turns on output.
