Fast Streaming with PicoScope 3425 no Aggregation

Postby Carsten » Mon Feb 18, 2013 9:16 am

Moin,

i need to aquire 1 sample / µs over a huge time ( 10 minutes +) on all 4 channels.
The SDK Examples are working fine, but the ps3000_fastStream.vi uses aggregation.
Is there a way to use fast streaming mode and get the unaggregated data constantly without any gaps in Labview ?
C++ example seems to work, but need Labview.


Example VI's would be perfect

Hi Carsten,

Referring to the Programmer's Guide, it should be possible to retrieve unaggregated data using the ps3000_get_streaming_values_no_aggregation() function. You would need to modify the LabVIEW example to incorporate this function once you have stopped the data collection or auto_stop is true.

The wait function will be needed in LabVIEW to avoid constantly polling the driver when calling the ps3000_ready function.

I hope this helps.
