Hi, there
Can anybody here tell me is the noise floor displayed on the SA in dBm or dBm/Hz, that is, what 's the meaning when marker sais -70dBm, is that the total noise power? or just the power spectral density around the frequency of interest? If it is power density, why does it not inclue /Hz at the end of reading?
TIA.
