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