Blockwise average

Post by Markus Mangold » Mon Aug 26, 2013 1:55 pm

Hello

I have a new PS5244B oscilloscope and I am writing my own software in LabView using the dlls provided by pico technology. Currently, I try to transfer as much data as possible between the oscilloscope and the computer using rapid block mode. With a maximum data transfer rate of nearly 30 MByte/sec I am basically bus limited (USB2.0 HiSpeed).
For my real application, however, I do not need all the data that I acquire. In fact, I could greatly reduce the amount of data to transfer (and by this the dead time after acquisitions) if I could blockwise average the data on the oscilloscope and transfer only the averaged data. What I need is not the functionality provided by the downsampling modes in ps5000aGetValues. I want to collect a number of blocks and average all first samples, all second samples, and so on... Is it possilbe to do such an averaging on the scope before I transfer the data?

Thanks for the help.
Regards, Markus

Hi Markus,

The driver does not provide such a feature, You would have to transfer the data and post-process it to average the data as per your requirement.

I will put forward your request as a feature enhancement.

Hi Hitesh

Thanks for your answer. For us, this feature would be a major improvement since we always acquire a big number of blocks which will be averaged. When you put forward such a request, is this a question of weeks or years until the feature is available? :roll:

Hi Markus,

It's something to be considered for the future but unfortunately not for the new PicoScope 5000 series as it would involve considerable work.

You would really have to post-process the data in LabVIEW.

Best wishes,

Hi

I'm still interested in on-scope blockwise averaging as asked for 2 years ago. Has this been implemented in any of your scopes meanwhile?

Cheers, Markus

Hello Markus,

Sorry to say this, but at this moment in time, this feature has not been implemented in any of our oscilloscope products.

I believe that the feature is still of interest so it is worth keeping looking at new product releases in the future to see if it has been implemented.
