Programming Examples
GPIB Programming Interface Examples
• resets the signal generator
• queries the instrument (CW frequency, power level, frequency mode, and RF state)
• reads responses into the rdBuffer (CW frequency, power level, and frequency mode)
• turns signal generator RF state off
• verifies RF state off
The following program example is available on the signal generator Documentation CD- ROM as visaex3.cpp.
//**************************************************************************************** // PROGRAM FILE NAME:visaex3.cpp
//
// PROGRAM DESCRIPTION:This example demonstrates the use of query commands. The signal // generator can be queried for conditions and instrument states. These commands are of // the type "*IDN?"; the question mark indicates a query.
//
//****************************************************************************************
#include <visa.h> #include "StdAfx.h" #include <iostream> #include <conio.h> #include <stdlib.h> using namespace std;

//Declares variables of type ViSession

//for GPIB verifications

// Declares variable to hold string data // Declares variable to hold integer data

//Initialize the VISA system

viStatus=viOpenDefaultRM(&defaultRM);

//Open session to GPIB device at address 19

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

if(viStatus){// If problems, then prompt user
