... 06aug11:tx sample voltages are displayed for the 1st ipp of the file (.ps) ( .pdf ): . ... Rdev setup for sine wave. 10 millisecond ipp fed into rdev from sps. sine wave= 30MHz+ 11160 hz, amp=14dbm. took 4 files of data (about 60 seconds/file). ... Page 2: Measure phase differences (Data[0] -Tx[0]) for 6000 ipps . ... The measured phase (tx to data) is off by about .5 usecs from the expected time difference. 2nd: phTxSmp[0,ipp+1]-phTxSmp[0,ipp]: The change in tx sample 0 from 1 ipp to the next. ...

... 2.3 Data acquisition Spectra generated by the Multibeam correlator contain the usual structure seen in spectra from other H i instruments: a bandpass spectrum which is the sum of the sky , ground and receiver temperatures multiplied by the product of the filters in the receiver chain; superimposed on this is a noise ... Note also that sources extended much beyond ,40 arcmin can be imaged poorly in HIPASS images because of the bandpass sidelobe effect described in Section 3.3. ...
