68 Agilent N518xA, E8663B, E44x8C, and E82x7D Signal Generators Programming Guide

Programming Examples

GPIB Programming Interface Examples

// Connect a GPIB cable from the PC GPIB card to the signal generator

// Enter the following code into the source .cpp file and execute the program

// ***************************************************************************************

#include "stdafx.h"

#include <iostream>

#include "windows.h"

#include "Decl-32.h"

using namespace std;

int GPIB0= 0; // Board handle

Addr4882_t Address[31]; // Declares an array of type Addr4882_t

int main(void)

{

int sig; // Declares a device descriptor variable

sig = ibdev(0, 19, 0, 13, 1, 0); // Aquires a device descriptor

ibclr(sig); // Sends device clear message to signal generator

ibwrt(sig, "*RST", 4); // Places the signal generator into a defined state

// Print data to the output window

cout << "The signal generator should now be in REMOTE. The remote indicator"<<endl;

cout <<"annunciator R should appear on the signal generator display"<<endl;

return 0;

}

Interface Check for GPIB Using VISA and C

This program uses VISA library functions and the C language to communicate with the signal

generator. The program verifies that the GPIB connections and interface are functional. Launch

Microsoft Visual C++ 6.0, add the required files, and enter the following code into your .cpp source

file. visaex1.cpp performs the following functions:

• verifies the GPIB connections and interface are functional

• switches the signal generator into remote operation mode

The following program example is available on the signal generator Documentation CD- ROM as

visaex1.cpp.
