Picoscope API Bitdepth

Post by labnet » Thu Oct 24, 2019 4:09 am

The Picoscope 4444 spec says acquisition can be 12bit, 14bit, 16bit etc, but the APIs have no provision for setting bit depth.
Questions.
-What bit depth is being used when data is acquired by the API?
-Can the bit depth be specified from the API?
-Why even have 12 & 14bits as selectable, why not always have the system in 14bit mode?

Please check the Programmer's Guide There are 4444 specific functions for set/get device resolution, setting the hardware filter and other functions.

The sampling speed is restricted to 50MS/s in 14bit mode, for 12bit mode you can get 1 channel: 400 MS/s,
2 channels: 200 MS/s, 3 or 4 channels: 100 MS/s

Thanks Martyn.
The API document I downloaded the website was R1 (not sure what link I followed to get an outdated manual), but the one in your link was R5 which had all the additional information for the 4444 series.
So, anyone reading this, check the revision of your API document!
