Generate Pulse Waveform 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.
-> FUNC PULS	//Sets the output to Pulse wave.
-> VOLT 5 VPP	//Sets the output amplitude to
	5 Vpp.
-> VOLT:OFFS 0	//Sets the output offset to 0.
-> PULS:PER 1	//Sets the pulse period to 1 s.
-> FUNC:PULS:DCYC 50	//Set the pulse duty cycle to 50%.
-> OUTP ON	//Turns on output.
