I not see any reason use in SAA2 1024 not calibrated point mode for CPU send (this need a lot of ram)
I test speed on H4 (on V2 result should be some) (thanks OneOfEleven for add points/sec measure):
1 segment 401 uncalibrated point - 570 points/sec
2 segments 802 uncalibrated point - 560 points/sec
4 segments 1601 uncalibrated point - 560 points/sec
8 segments 3201 uncalibrated point - 560 points/sec
This points/sec points received from device (in device speed more beeg, not need send data, i measure 401 points on CH0 and CH1 in 620ms so speed ~650 points/second, for only one channel ~930)
So no matter how many you measure points in one time (yes if enable calibration in device 1/3 time lost on calc interpolation for segment, but V2 not do this) in segment scan
So 1024 points not give result, but grab a lot of memory, this memory can be used for increase device points count
