Just a comment in general here. There is that decision to go boat anchor HP or new Chinese. For years, I went boat anchor. However the Rigol stuff is pretty good. [They OEM the cheaper Agilent gear.] You need to evaluate your goals for the instrument. If you working in a corporation and trying

I just had a discussion about older spectrum analyser versus the new Rigol type SA. They are saying the Rigol is -80dBc. Unfortunately I don't know what the specs of mine are. Could someone help me out with some noise floor figures for the following? * HP 8566A * HP 8568B *

Hi You really need to know a few things about the Rigol spec: 1) Is it simply a noise measure? If so, at what bandwidth and frequency (narrow will always be lower)? 2) Is it a signal spec? If so with what signal level and settings? Does it include / exclude IMD / harmonics? 3) Is it the spec
