Creating and Downloading Waveform Files

Programming Examples

end

%Save the data to a file

%Note: The waveform is saved as unsigned short integers. However,

%the acual bit pattern is that of signed short integers and

%that is how the Agilent MXG/ESG/PSG interprets them. filename = ‘C:\Temp\PSGTestFile’;

[FID, message] = fopen(filename,’w’);% Open a file to write data if FID == -1 error(‘Cannot Open File’); end fwrite(FID,waveform,’unsigned short’);% write to the file

fclose(FID);

% close the file

%3.) Load the internal Arb format file *********************************

%This process is just the reverse of saving the waveform

%Read in waveform as unsigned short integers.

%Swap the bytes as necessary

%Convert to signed integers then normalize between +-1

%De-interleave the I/Q Data

%Open the file and load the internal format data

[FID, message] = fopen(filename,’r’);% Open file to read data if FID == -1 error(‘Cannot Open File’); end [internalWave,n] = fread(FID, ‘uint16’);% read the IQ file fclose(FID);% close the file

internalWave

= internalWave’;

% Conver from column

array to row array

% If on a PC

swap

the bytes back to Little Endian

 

if strcmp( computer, ‘PCWIN’ )

% Put the bytes into

the correct order

internalWave=

bitor(bitshift(internalWave,-8),bitshift(bitand(internalWave,255),8));

end

 

 

 

 

%convert unsigned to signed representation internalWave = double(internalWave);

tmp = (internalWave > 32767.0) * 65536;

iqWave = (internalWave - tmp) ./ 32767; % and normalize the data

%De-Interleave the IQ data

IwaveIn = iqWave(1:2:n);

QwaveIn = iqWave(2:2:n);
