Hi The CNT-91 has a very high noise floor if you are trying to “see” phase noise. It also does not give you much in the way of frequency offset information. A single mixer setup running into a sound card is a *much* better approach if you are looking for another opinion vs the FSQ8. I have used the CNT 90 and CNT 91’s a lot. I have no experience with the FSQ8.
