The ATCA correlator has a mode whereby each correlator cycle (which is
normally the same as an integration cycle) can be
broken into a number of time bins. This capacity can be used in two
different modes:
- Pulsar bin mode: This mode is useful for a periodic signal with
a period much shorter than the correlator cycle, i.e. pulsars. In
pulsar bin mode, the bins produced by the correlator
correspond to the integration during a particular phase
of the pulsar cycle.
- High time resolution bin mode: This mode is useful for observations
which, for some reason, require higher time resolution than the normal
correlator cycle time (the minimum correlator cycle time is about
10 s). In this mode, the correlator cycle is broken up into a number of
finer time bins, effectively working around the minimum correlator cycle
time limit.
