Agilent Technologies U2761A manual FSK Rate, Generate FSK Modulation Using SCPI Commands, Example

2 Features and Functions

FSK Rate

The FSK rate is the rate at which the output frequency “shifts” between the carrier frequency and the hop frequency.

•The range of the FSK rate is 2 mHz to 100 kHz. The default FSK rate value is 10 Hz.

Soft Front Panel Operation

On the FSK Rate panel as shown in Figure 2- 22, input the desired FSK rate value and select the unit from the drop down list.

Remote Interface Operation

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

Generate FSK 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.
-> FSK:STAT ON	//Enables FSK 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.
-> FSK:FREQ 100	//Sets the "hop" frequency to
	100 Hz.
-> FSK:INT:RATE 10	//Sets the FSK rate to 10 Hz.
-> OUTP ON	//Turns on output.
