The broadband signal channels are transmitted to the Mopra Spectrometer, MOPS, installed in the Mopra equipment room via broad band analogue fibre optic links. Each 8-GHz IF is then split into four 2.2-GHz bandwidth channels and down converted to the base band.
Every 2.2-GHz base band IF signal is digitised by a 2-bit 4.4 Gsample/sec Indium Phosphide digitiser. The digitisers were developed at ATNF and fabricated at TRW in March 2000, under the CSIRO Special Executive program.
MOPS was comissioned on 14 October 2005 at Mopra by ATNF staff from
Epping and Narrabri.
