... multiple records containing an ascii data record header followed by 100 ipps of binary (short) data. ... The data taking program has two input buffers (100 ipps each). ... The power program and clp programs have different transmitter samples: . ... To automatically differentiate between power and clp ipps, the rms was computed (using the I sample) for tx samples 1000 thru 1500. ... The clp ipps had tx samples (so the rms would be large) while the power ipp was blanked (so the rms should be small). ...

While it makes sense for a 3-station array to only record data when all three stations are tracking the fringe (and this is why this mode was used with NPOI's 3-station configuration), NPOI 6-station data from the hybrid beam combiner are recorded even if up to three stations are in fringe search mode. ...
