Creating and Downloading Waveform Files

Programming Examples

% Calcurate waveform RMS

rms = sqrt(mean(abs(iqWave).^2)) / 32767;

% account for pulse duty cycle

pw = sum(abs(iqWave)>0);

dutyCycle = pw/length(iqWave);

rms = rms/dutyCycle;

% Interlace the I & Q vectors

data = [real(iqWave);imag(iqWave)];

data = data(:)';

end

function mkr = FormatMarkers( markers )

% The markers are placed in the 4 LSBs of a byte

% in this order M4 M3 M2 M1

[c,d] = size(markers);

if c>d

markers = markers';

[c,d] = size(markers);

end

mkr = (markers(1,:)~=0);

if c>1

mkr = mkr + 2*(markers(2,:)~=0);

end

if c>2

mkr = mkr + 4*(markers(3,:)~=0);

end

if c>3

mkr = mkr + 8*(markers(4,:)~=0);

end

function hdrCmd = CreateHeaderCommand( file_name, rms, header )
