There is now so much talking about noise floor and phase noise things including misunderstandings and mixing things etc.
Close carrier phase noise is better what I expect with specifications. Specifications tell only Phase Noise for 10, 100 and 1000kHz offset and only for 1GHz.
Here 2 images.
First one is 10MHz carrier in center and 5MHz LSB and USB. Here used 1kHz RBW
Second image is also 10MHz carrier in center and then 10kHz LSB and USB.
Both images have 3:1 RBW/VBW
10MHz signal come from HP Z3801 owen (quite good phase noise also in near carrier where it beats normal cheap Rb's just completely) and holdoff (GPS antenna shutted off).
In first image there is 4 traces.
Trace B is for reference without signal (and then freezed) with all same settings.
Trace A Detector is Positive Peak
Trace C Detector is Normal
Trace D Detector is VideoAverage
No any trace averaging in use so that no one can develop paranoid thoughts what is hidden using average.
Second image also have 4 traces.
Trace A detector is Pos Peak
Trace C is 20 times Trace Average from Detector: Pos Peak
Trace B detector is VideoAverage
Trace D is 20 times Trace Average from Detector: VideoAverage
Sidenote: When marker function is Noise marker do not use it for signal/peaks level measurements. It is NOT for this!
Simplified: It force marker source trace input from VideoAverage detector output. (this is ok (only) for purposes what it is designed as its name tell). But it is not direct value from VideoAverage detector output. It show "noise corrected" 1Hz normalized value.
I have not ispected what correction values they exatly use. (this factor depends many internal details in filter shapes and detector details etc. In some individual case it looks like this value was 2.5dB. (but my quess is that always in SSA3kX it is between 2.1 and 2.8dB (?))
So if you look VideoAverage and RBW is 1kHz... not -30dB from this but -27.5dB for Hz (noise).
