Creating and Downloading Waveform Files

Programming Examples

//1.) Create Simple IQ Signal *****************************************

//This signal is a single tone on the upper

//side of the carrier and is usually refered to as

//a Single Side Band Suppressed Carrier (SSBSC) signal.

//It is nothing more than a cosine wavefomm in I

//and a sine waveform in Q.

int points = POINTS; // Number of points in the waveform

int cycles = 101; // Determines the frequency offset from the carrier double Iwave[POINTS]; // I waveform

double Qwave[POINTS]; // Q waveform

short int waveform[2*POINTS]; // Holds interleaved I/Q data double maxAmp = 0; // Used to Normalize waveform data double minAmp = 0; // Used to Normalize waveform data double scale = 1;

char buf; // Used for byte swapping char *pChar; // Used for byte swapping bool PC = true; // Set flag as appropriate

double phaseInc = 2.0 * 3.141592654 * cycles / points; double phase = 0;

int i = 0;

for( i=0; i<points; i++ )

{

phase = i * phaseInc; Iwave[i] = cos(phase); Qwave[i] = sin(phase);

}

//2.) Save waveform in internal format *********************************

//Convert the I and Q data into the internal arb format

//The internal arb format is a single waveform containing interleaved IQ

//data. The I/Q data is signed short integers (16 bits).

//The data has values scaled between +-32767 where

//DAC Value Description

//32767 Maximum positive value of the DAC

//0 Zero out of the DAC

//-32767 Maximum negative value of the DAC

//The internal arb expects the data bytes to be in Big Endian format.

//This is opposite of how short integers are saved on a PC (Little Endian).

//For this reason the data bytes are swapped before being saved.
