aggregation process and hardware
Hello,
I'm working to a program (mingw C with Picoscope SDK API) to acquire a continuous stream of data. I am wondering if the aggregation process (RATIO_MODE_AVERAGE) is made in the oscilloscope hardware or by the driver after the data transfer. I have now a Picoscope 5444B.
I need this info also for the Picoscope 4824 as I am planning to buy this new unit to profit by the USB3 transfer speed.
Kind regards,
Michele

Re: aggregation process and hardware
Sorry for the slow reply due to the current situation.
The averaging will be performed on the device if the down sampling ratio is greater than 8, otherwise it is performed in the driver. When using downsampling the raw data will still be sent over the USB bus, the driver keeps a raw data buffer equal to the sum of pre trigger and post trigger samples for use by the PicoScope application.
