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).
