Set Frequency Sweep 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 SIN //Sets the carrier waveform to
Sine wave.
-> VOLT 5 VPP //Sets the output amplitude to
5 Vpp.
-> VOLT:OFFS 0 //Sets the output offset to 0.
-> SWE:STAT ON //Enables frequency sweep.
-> FREQ:STAR 500 //Changes the start frequency to
500 Hz.
-> FREQ:STOP 10000 //Changes the stop frequency to
10 kHz.
-> SWE:SPAC LIN //Changes the sweep mode to
Linear.
-> SWE:TIME 2 //Changes the sweep time to 2 s.
-> TRIG:SOUR EXT //Changes the sweep trigger
source to External.
-> TRIG:SLOP POS //Changes the U2761A to be
triggered on the rising edge.
-> OUTP ON //Turns on output.
