P170mm - ultra broad-band prime focus receiver (1300-6000 MHz)

This is an ultra broad band (UBB) 2-channel system covering a range from 1300 to 6000 MHz.

Comments:

The system delivers two basebands, 1.3-2.6 GHz and 3.0-6.0 GHz. Currently, it is only possible to record both bands in parallel for pulsar observations (timing and search mode), but not yet for continuum or spectroscopic observations.

Version	Description	Details
EDDPOL	spectro-polarimeter backend for continuum observations in the lower band	with 64k channels
EDDPOL3G	spectro-polarimeter backend for continuum observations in the upper band	with 64k channels
EDD_PULSAR_TIMING	pulsar folding mode observations	coherent dedispersion, configurable channels and subints
EDD_PULSAR_SEARCH	pulsar search mode observations	coherent filterbank, configurable channels and time samples (down to 32$\mu$s)
