Agilent Technologies U2761A manual Phase Deviation, Generate PM Using SCPI Commands, Example

Features and Functions 2

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

0to 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.
