4 Gbps frequency status
Please enter here your receivers with their frequency ranges. Please keep this table up to date!:
- At which sky frequency (or frequency ranges) can your telescope reach 2*512 MHz (dual polarisation)?
- Which IF output can your telescope provide? For example IF: 500-1000
- What limits on LO tunability do exist?
Ranges in GHz, widths in MHz; in cells: top - width, middle - range, bottom - LO tunability
