I have a quick question for the group about the noise floor of a
spectrum analyzer, hope that with the collective knowledge and
experience somebody can help me out a bit.
We have customer that needed a couple of site surveys done, in order
to detect any possible interference sources on 3 segments
Remember, the narrower the bandwidth on something the more sensitivty
it can get. Theoretical sensitivty is -174dB, problem is that is at
1Hz of bandwidth.
I would recommend slowing the sweep rate, narrowing the IF filter and
taking smaller sweeps at a time. a 100kHz sweep with 10kHz per
division
As was previously posted, you need to slow down the
sweep speed and/or narrow the resolution or video
bandwidth, which may automatically slow down the sweep
speed. The filtering is done digitally in most modern
SAs, and this takes time, so the sweep is slowed down
to accomodate this. You don't

Could anybody clarify how one does lower the noise floor of the
analyzer? It was my understanding that the noise floor is a intrinsic
characteristic of the instrument itself, and is so to say a
measurement limit that cannot be varied without external aids (or
