The driver returns data from the device in ADC Counts - this will result in values between -32512 and 32512 which correspond to the minimum and maximum value for the voltage range selected. The jump between 0 and -256 is most likely an ADC count value.
What signal are you feeding in? Can you provide some example data values or show a plot of the data received?
I am having troubles to run the MATLAB examples using my PS 2206B, 64-bit MATLAB 2014a .
I think I have configured everything properly because I have done this before for my PS5444B. I have copied the drivers, installed the most recent SDK and Picoscope software, etc. I also have tried with the PS2000 and PS2000a drivers. Sometimes even the Picoscope waitbar appears as usual and then it closes.

So, I would like you to provide me some guidance for being able of running the examples with my PS2206B.
This is quite urgent.
