Hi, I got pico 3204 and generally like the unit and its software interface. Without much struggle I received 10MSamples per sec of data transfer rate in rapid block mode. Now I want to double that to match half of USB2 specs at about 20 MB/s. What caught my attention is the data transfer format of the type short. Why it is 16bit and not 8bits, equal to what ADC has? Is there a faster interface to the board ?
Thanks. Boris /specman4epr.com/
Hi Hitesh, thank you for reply. The A variant.
The code I used to measure the transfer speed was written in C (BCB XE4).
Now I tried to write similar code in MATLAB and the transfer speed went down to 30 kB/s. Any experience with MATLAB transfer speeds ? Do you think it worth fighting or better to move the acquisition to mex ?

HI Hitech,
MATLAB is 32-bit 2013b (64bit did not work).
The main difference is the absence of the Bulk data transfer function (ps3000aGetValuesBulk). I did not manage to make it working. Example is using ps3000aGetValues.
