The buffer size is allocated based on whether it’s a finite or continuous scan. For a finite scan, the buffer allocated is the number of samples in the scan. For continuous, its based on the selected sample rate. More information on this topic is available at:

Hello, I am looking at your specifications. Can you please tell me if my math is correct? I would like to know the maximum sample rate in ms of the Data Acquisition if I have 64 Analog Input Channels. (((320,000 Samples/s)/(64 Channels))*(0.001 s/ms))*(ms/Sample) = 0.2 ms/(Sample*64Chanels). So for 64 Channels the sample rate or (scan time) would be 0.2ms . Is this correct?

Yes, your calculations are correct. Sample rate in mSec for 64 channels will be 0.2 mSec per channel (5000 Hz). Please take into account that the load on the Raspberry Pi processor can affect the overall sample rate. For optimal results it is recommended that you use a Raspberry Pi 3 B+ or Raspberry Pi 4.

Can we reach the 100kS/s on a single channel, or on multiple channel ?

The MCC 128 has a max sample rate for a single board of 100kS/sec. This is for a single channel or multiple channels. If multiple channels are to be used, divide the sample rate by the number of channels to calculate your per channel rate.
