The system comprises 2 feeds, 4 channels and 2 Broadband Polarimeters. 8 data channels, 2 total
power and 2 polarization signals per feed are recorded. This total power system is being used in a
"software beamswitching" mode to observe extended sources. The feeds are mounted in a row in
azimuth direction, having a distance of approximately 3 arcmin. The frequency scheme is fix, the receiver
has built-in local oscillators that can't be changed.
The RF-filter is essential to protect against TV-satellites.
The system needs special offline reduction programmes.
