Looking at the specs for the 6000, and following the posts, I think that I understand how it works. Is the following simplification correct?
For the up to 70 MHZ band, as an example, there is an ADC that is sampling the received data at a rate of at least 140MHZ within a Spectral Capture Unit (using an ADC that's somewhat faster than the one on my Arduino), corresponding to the Nyquist sampling frequency. By sampling at 2X the highest frequency desired, the entire band can be recreated. The sampled digital data is then further processed within a 6000 processor to separate out "received slices" for the bands desired. This is a design that is somewhat hard to comprehend. I have not done any signal processing in software since about 45 years ago when it was a challenge to sample data at 8KHZ. Please elaborate and correct my erroneous thinking if you choose to comment on this.
