Does the ADC-11 have buffer memory for 'Fast block recording' or is it really just streaming?

The ADC-11 does not have buffer memory for 'Fast block' mode; however, the sampling interval is fixed by the logger. In this way, effective behaviour is 'Fast block' even though actual operation is 'Streaming'.

The ADC-11 and the PC both have performance limits and will rarely be able to give exactly the settings that are requested. Thus, in ‘Block Mode’, PicoLog software will negotiate the requested settings based upon one of two user options:

a) The total collection time remains constant - Here, the time will remain very similar to that requested and the number of samples will be compromised to achieve that.

b) Number of samples remain constant - Here, the number of samples will remain very similar to that requested and the collection time will be compromised to achieve that.
