Re: Hp8558b spectral analyzer (2/2)

Paul, thank's for your answer. That¡¯s the problem, I¡¯ve never been able to display a signal with the RF plug.In fact, my first question was whether this catch was smeared because you can¡¯t see the silkscreens. There was supposed to be a BNC. It seems to be well connected to the attenuator input.
for display something:

My second question was also to know which positions should be the main buttons to display a 20MHZ AM signal with a voltage of 0.3V.I¡¯ve tested many combinations, we don¡¯t show any signal. Some ideas?
Indeed, by chance when I connected the calibration output to the LO socket, I display something. I know that¡¯s not the way it¡¯s supposed to work, it¡¯s really strange. It proves that some things work.
Normally input cable must be do like that (I thing)
on my analyzer it's like a small aluminium coaxial cable (2/3 mn diametral) from RF N input to the attenuator.
So the capacitor and other are directly on the plug and i don't see it? Capacitor burn???
I¡¯m going to test this cable, even if it means injecting a signal directly into the attenuator input with a 0.1 ?f capacitor whith a small signal?
