4 Gbps frequency status

Please enter here your receivers with their frequency ranges. It should help us to identify the best ranges for 4 Gbps observations, 2*512 MHz (dual polarisation). Please keep this table up to date!

For each receiver please privide:

  • Available bandwidth in MHz.
  • Which IF output can your telescope provide? For example IF: 500-1000
  • Total frequency range in GHz
  • What limits on LO tunability  do exist? Step size.
  • Type of polarization
  • IF inputs for scheduling (e.g. A, B, A1, C3, ...)
  • normal or typical LO value(s).
