Importing and Downloading I/Q Data—Big Endian Order

On the documentation CD, this programming example’s name is “impDwnLd_c++.txt.”

This C++ programming example (compiled using Metrowerks CodeWarrier 3.0) assumes that the data is in big endian order and performs the following functions:

•error checking

•binary file importing from the PC or workstation.

•binary file download to the signal generator.

//Description: Send a file in blocks of data to a signal generator

#include <sicl.h> #include <stdlib.h> #include <stdio.h> #include <string.h>

//ATTENTION:

//- Configure these three lines appropriately for your instrument

//and use before compiling and running

//

char* instOpenString = "gpib7,19"; //for LAN replace with “lan[<hostname or IP address>]” const char* localSrcFile = "D:\\home\\TEST_WAVE"; //enter file location on PC/workstation

const char* instDestFile = "/USER/BBG1/WAVEFORM/TEST_WAVE"; //for non-volatile memory //remove BBG1 from file path

// Size of the copy buffer

const int BUFFER_SIZE = 100*1024;

int main()

{

INST id=iopen(instOpenString); if (!id)

{

fprintf(stderr, "iopen failed (%s)\n", instOpenString); return -1;

}

FILE* file = fopen(localSrcFile, "rb"); if (!file)

{

fprintf(stderr, "Could not open file: %s\n", localSrcFile); return 0;

}
