> My guess is well into 6 figure$. It's a modular system like its 3048A and E5500-series forebears, so the only limits are your imagination and your bank account. :) Very cool hardware, noting that it has some competition from all-in-one instruments like the FSWP that the earlier 'doomsday machines' didn't have to face.
I'm sure you could spend a quarter of a million dollars on either the FSWP or the N5511A if you checked all the boxes. > BTW, I don't know what -177 dBm/Hz has to do with phase noise. > The relevant units are dBc/Hz as any time-nut knows. I haven't seen PN analyzers rated that way before, but it makes sense to a certain extent. They are basically saying they can measure the noise on a 0 dBm signal down to -177 dBc/Hz, with signals above 0 dBm being measurable with a commensurately-lower floor. Their rated power limit is +20 dBm, so -197 dBc/Hz would be the theoretical limit. The brochure goes into that in some detail, but there's no mention of cross-spectral collapse, which I thought was interesting. The white-noise floor in their example plots is enviably flat, with no divots, suspicious-looking valleys or other artifacts. If they are able to avoid that problem in the general case, it would be interesting to hear more about the strategy being used. -- john, KE5FX Miles Design LLC / Jackson Labs Technologies, Inc. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
