GPIB Programming Interface Examples
// PROGRAM DESCRIPTION:This example program verifies that the GPIB connections and
// and interface are functional.
// Turn signal generator power off then on and then run the program
//
//****************************************************************************************
#include <visa.h>
#include <stdio.h>
#include "StdAfx.h"
#include <stdlib.h>
void main ()

// for instrument communication
ViStatus viStatus = 0;
// Opens a session to the GPIB device
// at address 19

viStatus=viOpen(defaultRM, "GPIB::19::INSTR", VI_NULL, VI_NULL, &vi);

printf("Check instruments and connections\n");
printf("\n");
exit(0);}
viPrintf(vi, "*RST\n"); // initializes signal generator
// prints to the output window
printf("The signal generator should now be in REMOTE. The remote indicator\n");
printf("annunciator R should appear on the signal generator display\n");
printf("\n");
viClose(vi); // closes session
viClose(defaultRM); // closes default session
}
Local Lockout Using HP Basic and GPIB
This example demonstrates the Local Lockout function. Local Lockout disables the front panel signal
generator keys. basicex2.txt performs the following functions:
• resets instrument
• places signal generator into local
• places signal generator into remote
