The Velleman PCSGU250 is a combination 2-channel oscilloscope and function generator. This MATLAB Support package allows you to:
* configure scope properties such as triggers and time range
* retrieve waveforms from the scope
* configure the function generator
* create custom waveforms for the generator
The Support Package uses a Software Development Kit (SDK) from Velleman, and *does not* require Data Acquisition Toolbox or Instrument Control Toolbox. The included REAMDE.pdf guides you through the download and install of the Velleman SDK and related USB driver.
% create a Velleman PCSGU250 object
lab = vellscope.pclab
% hide the Velleman PCSGU250 GUI
% configure and start the function generator
lab.FgenFunction = 'sine';
lab.FgenFrequency = 20;
lab.FgenAmplitude = 2;
% configure and collect data from the scope
lab.VoltsPerDiv_Ch1 = '3V';
lab.TimePerDiv = '2ms';
pause(5) % wait to let scope acquire data
data = a.readChannel(1);
% clean up

May i ask you a question?
readChannel gives me, as indicated in README document, the last 4096 samples acquired by the scope: what is the sample rate? It is possible to vary it (as indicated in pcsgu250 specs)?
