File Information
Description

For the Picoscope oscilloscopes, drivers are downloadable from their website www.picotech.com . They do support Linux, Micrsoft excel and some more software packages.

Matlab was not found in this list. There is a solution:

Place the files PicoMatlab.m , PS2000.dll and ps2000.h (last two files are in the 'development kit' which is available from the website of picotech) in one directory and run the Matlab program ‘PicoMatlab.m’ from that directory.

'Picomatlab' is a small example program is written showing how to use some of the functions in the DLL. The program will opens a screen and the analyzer is initialized.

Setting the range of a (connected) oscilloscope type Picoscope 2205 to the lowest range and pressing ‘start’ will result in a similar image as seen above. The time base can be adjusted also. Numbers shown represent the actual data sent and clarification of these numbers can be found in the included file ‘PS2100.en.pdf’, which is also found on the webste of picotech.

The ranges are in this program set for the Picoscope 2205, other types may require an adjustment of the available ranges.

The button ‘LED’ flashes the led on the analyzer three times.

Pressing ‘Exit’ will exit the program, as well as depressing the ‘exit cross’ in the figure.
