Matlab Tools

afg31k_wfm

Example usage:

Creating an impulse, shortest width possible at 500 Msample/sec rate

Waveform length is 20 microseconds ((1/500M) * 10000):  
    a = zeros(1,10000);
    a(1) = 1;
    afg31k_wfm(a, 'impulse.wfm', 500e6, 'nearest');
play out using Advanced Mode, set Timing to 500 Msample/sec

Creating a 2-second convex chirp between 100Hz and 400 Hz,

Amplitude: 1Vpeak (2Vpeak-to-peak) if 50 ohm load.
    t = -1:0.001:1;          % +/-1 second @ 1kHz sample rate
    fo = 100;
    f1 = 400;                % Start at 100Hz, go up to 400Hz
    ycx = chirp(t,fo,1,f1,'q',[],'convex');
    soundsc(ycx, 1000);      % Listen to the sound
Up-sample to 10 ksps (just for example) using spline interpol.:
    afg31k_wfm(ycx, 'convex_100_400_10k.wfm', 1000, 'spline', 10000)
play out using Advanced Mode, set Timing to 10 ksample/sec
