HP8590A Spectrum Analyser - Installation and Initial Verification checks...
807:
@MostlyHarmless...yep, that's the video I saw. He replaces the 2 RF dides with an SMD dual schotky device.
Definitely looks like your noise floor is around 8dB or so too high.
The 300MHz CAL signal generator must be different on the 8591E. The harmonics are higher on my model compared to the 8590A.

I just acquired one of these so will be watching this thread with interest. No idea when I will do a full check on mine but did see that the cal signal is correct & the full frequency range could be seen using a comb generator. Currently trying to coax a Datron 4707 back to life.
