Picoscope software 10MS/s streaming, 4444 capable of 50MS/s

Postby nurber » Wed Sep 06, 2017 1:30 pm

Hi Forum. Why is Picoscope software only capable of 10MS/s USB streaming when, for example, 4444 is capable of 50MS/s ?

The SDK can go to 50 or even higher.

I hope someday pico decides to increase this limit for the USB3 type of scopes
Also the max 100MS limit is sometimes on the low side.

Thanks for reply. I'd like to use the mask or persistence to show glitches over time without the need to record data. I'm not sure what sample rate is needed yet, but I noticed this limitation in documentation. Also see that automotive scope is capable of 20MS/s.

Hi nurber and bennog,

Our USB 3.0 products can sample at up to around 20 MS/s with the PicoScope 6.12 software when used with a USB 3.0 connection, and the PicoScope 4444 can sample at up to around 16.67 MS/s.

The reason for the limitation is historically down to preserving PC resources, but as technology moves on this may well be reconsidered. I will notify the Development Team of your comments.

Regards,
Hitesh
