Standard parameters of the 2.3-8.3 GHz coaxial receiver
It is possible to use the receivers both together (coaxial, 2 IF outputs, one per each frequency) and separately (2 IF outputs). For the VLBI coaxial observation one channel only for each receiver is used, typically the right polarization one (this because the Mark IV can handle only 2 IF inputs).

The available bandwidths may be considered less then what is reported because of interferences.
