Hi Dan Thanks for your input. For 800 MHz BW, I am looking for 2048 spectral channels. If that is a tall order, we could settle for 1024. I am hoping to double the number of channels for halving the BW. For eg. BW NumChannels 8002048 4004096 2008192 I see why you are suggesting

John We do have switchable analog filters that define the 200, 400 and 800 MHz bandpasses in our IF processors. So decimation in sample domain should still work. Yes, that's true. In our case we want to avoid the complexity of switching in various bandpass filters for the narrowband case.

Hi Richard, Do you have the USB cable connected a terminal program running, where you can watch it boot up? If so, once you hit any key to interrupt the boot, you type: setenv bootcmd run netboot saveenv That should do it. Jason On Fri, 21 Mar 2014, Richard Black wrote: Hi all, I'm

Hi John If you can sample 800 MHz bandwidth, then can't you use a digitial bandpass filter to get to the lower bandwidths? Gerry On 3/21/2014 11:43 AM, John Ford wrote: John We do have switchable analog filters that define the 200, 400 and 800 MHz bandpasses in our IF processors. So
