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.
