// Prototype C++ client application for "Fast Wave Port' Math Processor

// Compatibility:

// Microsoft Visual C++ 6.0, 7.1

// MinGW 'gcc' based compiler (free download from http://www.mingw.org/)

// Compile with: mingw32-c++ -o fastWavePortClient.exe fastwaveportclient.cpp

//---------------------------------------------------------------------------------------

#include "windows.h"

#include <stdio.h>

//---------------------------------------------------------------------------------------

// FastWavePort header, describes various properties of the waveform passed to the

// user-processing

// function. Also used to carry the properties of the processed waveform back to the

// DSO.

#define FLAGS_OUTPUT_VALID 0x01

struct CDescHeader

{

int descVersion; // header version number

int flags; // misc. flags indicating the status of input, and

// how to treat the output

int headerSize; // size of the header, data starts immediately after

// the hdr.

int windowSize; // total size of the window (header + data)

int numSamples; // total number of samples in the input waveform

int segmentIndex; // index of this segment, usually zero when input

// waveform is not a sequence

int numSweeps;

int _dummy1; // not used

double verGain; // scale factor that relates integer sample data

//values to the vertical units of the waveform.

double verOffset; // vertical offset (in vertical units, e.g. Volts) of

// the waveform

double verResolution; // vertical resolution of the measurement system (also

// in vertical units)

double horInterval; // scale factor that relates integer sample indices to

// the horizontal units of the waveform.
