content: Someone asked me if connecting to the NRQ6 to the NRX gives you the frequency selectivity, the short answer is yes. But I could not find any control over the IF BW in the GUI of the NRX. I will asked R&S as well.

content: These are really cool! I wonder what factors go in to making a receiver capable of competing with traditional power sensors on accuracy and stability. Getting rid of YIGs is probably the bulk of it, and then at the very least a lot of validation... but I wonder what else there is. Just how far could one go with a calorimeter, some good attenuators, and a batch of RTL-SDRs? Not to 40GHz, but it might be a fun project.
