We can currently read out the entire correlator in 0.25s. Thus you can get s for any configuration that satifies eq.(4).
Of course, one disadvantage of short and/or large
is that the size of your output data grows all the more quickly.
To look at how big your dataset might become, start with a single board, which
outputs 48kB of data per integration, 32kB of which
is lag-based correlation data and 16kB of which is header information.
Considering only the correlation-function data portion and converting
to frequency-space
(
) yields 0.5MB per integration for the whole
correlator. We can calculate a
fraction of ``equivalent correlator usage":
