[QUOTE="s-band, post: 1136035, member: 407744"] Curiosity? Because it's possible? Because you have one? I use the lower range on some Ka LNBs to get 2GHz span. In those cases there isn't usually anything strong in the upper part. I didn't think it was programmable but am not 100% sure. I used an external anti-alias filter but that means routing the DC around it to power the LNB. Using this comb of signals with a 20MHz spacing and 5dB level difference the alias products can be easily seen: [ATTACH alt="9tone.PNG"]145159[/ATTACH] Centre frequency of comb set to 2.3GHz: [ATTACH alt="2.3GHz.PNG"]145160[/ATTACH] [/QUOTE]
