If you have a GPIB card, you can use a simple program like this to log data
points in a range of spectrum. This was for an HP spectrum analyzer, but if
you're using visa it shouldn't matter.
// SpectrumSurvey.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <visa.h>
#include <windows.h>
#include <iostream>
#include <fstream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
ofstream OutputFile("spectrum.dat", ios::out);
if (!OutputFile)
{
cerr<<"File could not be opened"<<endl;
return -1;
}
ViSession defaultRM, vi;
char buf [256] = {0};
char buf2 [256] = {0};
// set the parameters for measurement: in kHz
int StartFreq = 210000;
int StopFreq = 240000;
int StepFreq = 25;
int NumberRuns = 1;
// write out the frequencies in the header
int CurrentFreq = StartFreq;
while (CurrentFreq < StopFreq)
{
OutputFile<<CurrentFreq<<", ";
CurrentFreq += StepFreq;
}
OutputFile<<endl;
// Open session to GPIB device at address 18
viOpenDefaultRM (&defaultRM);
viOpen (defaultRM, "GPIB5::18::INSTR", VI_NULL,VI_NULL, &vi);
viPrintf (vi, "ID?\n");
viScanf (vi, "%t", &buf);
printf ("Instrument identification string: %s\n", buf);
double ChannelPower;
// main loop to do measurements
for (int n = 0; n < NumberRuns; ++n)
{
CurrentFreq = StartFreq;
while (CurrentFreq < StopFreq)
{
viPrintf( vi,"IP;SNGLS\n");
viPrintf(vi, "FA %dMHZ\n", CurrentFreq);
viPrintf(vi, "FB %dMHZ\n", CurrentFreq+StepFreq);
viPrintf(vi, "CHP\n");
Sleep(1000*10);
viPrintf(vi, "*CHPWR?\n");
viScanf(vi,"%lf",&ChannelPower);
OutputFile<<ChannelPower<<", ";
CurrentFreq += StepFreq;
}
OutputFile<<endl;
}
viClose (vi);
viClose (defaultRM);
return 0;
