C++ Programming Example

This program demonstrates the use of lists and triggered measurements in a Keysight N3300A Electronic
Load. The load is programmed to step through three values of current at 1 second intervals. At each
current step, the load measures its own current by sampling it 50 times at 10 microsecond intervals. The
program reads back all of the data, averages the 50 samples for each of the three current steps, and
outputs the results. After each current step, the measurement is delayed by 100us to allow the current to
settle.
#include <stdio.h>
#include <stdlib.h>
#include "sicl.h"
#define MEAS_BUF_SIZE 4096 /* Size of measurement buffer in load. */
/* SICL error handler */
void ErrorHandler(INST id, int error)
{
printf("SICL error %d\n", error);
exit(1);
}
/* Each triggered measurement consists of nPoints samples.
* triggered measurements are taken, all of the samples (nPoints times the
* number of measurements) are placed in the load's measurement buffer.
* This function averages the samples in the buffer that are associated
* with one triggered measurement.
* nPoints samples are averaged; when nIndex is 1, the 2nd set of nPoints
* samples are averaged; etc.
