Frequency ranges for 2/4 Gbps

    Table of contents
    No headers

    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).
