Agilent Technologies U2761A manual ASK Rate, Generate ASK Modulation Using Scpi Commands

Features and Functions 2

ASK Rate

The ASK rate is the rate at which the output amplitude “shifts” between two preset amplitudes. The range of the ASK rate is 2 mHz to 100 kHz. The default ASK rate value is 10 Hz.

Soft Front Panel Operation

On the ASK Rate panel as shown in Figure 2- 26, input the desired ASK rate value and select the unit from the drop down list.

Remote Interface Operation

ASKey:INTernal:RATE {<rate in Hz>}

Generate ASK Modulation 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.
-> ASK:STAT ON	//Enables ASK modulation.
-> 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.
-> ASK:INT:RATE 10	//Sets the ASK rate to
	10 Hz.
-> OUTP ON	//Turns on output.
