The following program example is available on the signal generator Documentation CD- ROM as visaex11.cpp.

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

//PROGRAM FILE NAME: visaex11.cpp

//PROGRAM DESCRIPTION: This program sets up the signal generator to

//sweep from 1-2 GHz. A loop and counter are used to generate 5 sweeps.

//Each sweep consists of 101 points with a .01 second dwell at each point.

//The program uses a Sleep function to allow the signal generator to

//complete it's sweep operation before the INIT command is sent.

//The Sleep function is available with the windows.h header file which is

//included in the project.

//

//NOTE: Change the TCPIP0 address in the instOpenString declaration to

//match the IP address of your signal generator.

//

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

#include "stdafx.h" #include "visa.h" #include <iostream> #include <windows.h>

void main ()

{

ViStatus stat;

ViSession defaultRM,inst;

int npoints = 101; double dwell = 0.01; int intCounter=5;

char* instOpenString = "TCPIP0::141.121.93.101::INSTR";

stat = viOpenDefaultRM(&defaultRM);

stat = viOpen(defaultRM,instOpenString,VI_NULL,VI_NULL, &inst); // preset to start clean

stat = viPrintf( inst, "*RST\n" ); // set power level for -10dBm

stat = viPrintf(inst, "POW -10DBM\n");
