Any spectrum analyzer should do the job. Just take a look at the
sensitivity of the unit to ensure it will pick up small signals. I am
partial to the HP (Agilant) (spelling may be wrong here) spec ani's, but
you gotta pay out the nose for those.

The Advantest units are cheaper, and also work very well.

I do not think a scanner will do what it is you want and an analyzer is the
answer to finding your problem.

Can you recommend any particular analyzer for this application? I
think a lower-end handheld unit is probably the way to go. Since I'm a
newbie I don't think I need the more advanced functions that the
really big units provide.

I was just doing a quick search and ran across the Anritsu 2711D. That
seems to be a pretty nice unit and I doubt it would cost very much to
rent for a couple of weeks. The documentation seems to be clear and it
seems to be easy to use.

Any suggestions?

Thanks again,
John

Get a spectrum analyzer.

I have a business site that is suffering from rather dramatic EMI/RF
noise that is causing problems with both the voice and data networks.
I see a lot of errors due to noise on the data network, and the
handset cords on our user's phones pick up a rather painful
intermittent static burst.

I have a handheld EMI detector but it's not a scanner and doesn't
tell me what frequency is actually causing the problem. I think I
know the source of the problem but I need some help nailing it down.

I'm considering the Opto Digital Scout since it appears to do what I
want. My hope is that I could send this to the site and have them let
it run for a few hours, and then look through the logs to see what
frequencies are being hit. My best guess is that the offending source
is in the HF to VHF range, but that's just a guess.

Would the Digital Scout be a good choice for this sort of
application? I could hire someone to do an on-site analysis but that
would probably cost more than buying the Scout on my own.

Any thoughts?

Many thanks,
John
