12 Agilent 81133A/81134A Pulse Generator Programming Guide, March 2007

Example for Connecting via GPIB

The following code example shows how to use the VISA library to

connect to the instrument via GPIB.

This example queries a GPIB device for an identification string and

prints the results.

Implementation

#include <visa.h>

#include <stdio.h>

void main () {

ViSession defaultRM, vi;

char buf [256] = {0};

/* Open session to GPIB device at address 22 */

viOpenDefaultRM (&defaultRM);

viOpen (defaultRM, "GPIB0::22::INSTR", VI_NULL,VI_NULL, &vi);

/* Initialize device */

viPrintf (vi, "*RST\n");

/* Send an *IDN? string to the device */

viPrintf (vi, "*IDN?\n");

/* Read results */

viScanf (vi, "%t", &buf);

/* Print results */

printf ("Instrument identification string: %s\n", buf);

/* Close session */

viClose (vi);

viClose (defaultRM);

}
