seg_arb_define

This command loads a waveform from an existing full-arb waveform file.

int arb_file(int instr_id, long chan, char *fname);

Use this command to load a waveform from an existing full-arb .kaf waveform file into the pulse

card. You can load a full-arb waveform for each channel of the pulse card. Once loaded, use

pulse_output to turn on the appropriate channel, and then use pulse_trig to select the trigger

mode and start (or arm) pulse output.

When specifying the fname, include the full command path with the file name. Existing .kaf

waveforms are typically saved in the ArbFiles folder at the following command path location:

C:\s4200\kiuser\KPulse\ArbFiles

You can create a full-arb waveform using KPulse, and then save it as a .kaf waveform file (refer to

(on page 10-1) for details).

You can modify a waveform in an existing .kaf file using a text editor or KPulse.

arb_file(VPU1, 1, "C:\\s4200\\kiuser\\KPulse\\ArbFiles\\SINE.kaf")

This example loads a full-arb file named SINE.kaf (saved in the ArbFiles folder) into the pulse card for
