I'm looking for a USB spectrum analyzer for occasional use.
My immediate requirement is to cover the range 100kHz to 3MHz but up
to 30MHz would be good.
Any recommendations based on personal experience?
Hello,
You can try them :http://www.spectran.com/
we have bought one of their RF series (HF6060-V4), usable for qualitative
measurements at least if you connect it to a PC (the local LCD is, well,
limited). Not top range performances, but cheap.
Friendly,
Robert
Would be nice if they made one for the typical EMC pre-compliance range
from 150kHz to 1GHz. Had a chat with the key designer, and it seems they
either don't see that market or don't want to play there (which would be
very weird).

How does yours behave in the presence of large inband signals?

I would recomend the HF-60100 V4. We use it for our EMC tests and it
works nice even down to 150kHz (on the website they only talk about
1MHz, propably thats the "made in germany" reserve...).


Yeah, I was told it does go lower than the data***. However, the V4 is priced quite steeply.


Just as a note: For EMC tests dont forget that you need to add some
options to that unit like internal and external preamp and a biconical
antenna "BicoLOG 30100". Anyway its still much cheaper then EMC tests
in a lab :-)


This is pretty cool:

Anyhow, it all pre-compliance and doesn't replace the trip to the EMC lab. The measurement precision is quite a bit different there. The last step must be unobstructed free range and properly weighted receiver logging. In winter that's not always pleasant but it has to be done.
