... This can take dual-polarization data at a 10-MHz rate with quantization at 2 bits, or at slower rates with higher level quantization. To use this option, the user needs to connect the last part of the signal path manually via cables. ... Secondly, the data can be recorded via the spectral-line correlator, and measurements treated as spectral-line observations in which the spectral channels are collapsed across frequency during analysis to give a broad-band continuum signal. ...
