RIGOL Chapter 3 Programming Demos

3-24 DSA800 Programming Guide

1. Edit the DemoForDSA.h header file and declare a class to encapsulate the operation and property of

the instrument.

#ifndef DEMO_FOR_DSA_H

#define DEMO_FOR_DSA_H

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <iostream>

//#include <syswait.h>

using namespace std;

#define MAX_SEND_BUF_SIZE 50

#define MAX_REC_SIZE 300

class DemoForDSA

{

// Construction

public:

DemoForDSA();

bool InstrRead(string strAddr, string & pstrResult);

bool InstrWrite(string strAddr, string strContent);

bool ConnectInstr();

string m_strInstrAddr;

string m_strResult;

string m_strCommand;

};

void makeupper(string & instr);

#endif

2. Edit the DemoForDSA.cpp file to realize various operations of the instrument.

#include "visa.h"

#include "DemoForDSA.h"

DemoForDSA::DemoForDSA()

{

m_strInstrAddr = "";

m_strResult = "";

m_strCommand = "";

}

bool DemoForDSA::ConnectInstr()

{

ViUInt32 retCount;

ViStatus status;

ViSession defaultRM;

ViString expr = "?*";

ViPFindList findList = new unsigned long;

ViPUInt32 retcnt = new unsigned long;

string strSrc = "";

string strInstr = "";

ViChar instrDesc[1000];
