Hey Marlon, This may be a great opportunity for us to help some folks talk about spectrum analyzers here. What are you using today? I'm using the anritsu spectrum master. Expensive but I've been very happy with it. Maybe we should get some bullet points together.

EC also has a very nice portable unit (much easier to use) that's available for rent. Or they have them for sale if you're looking for something to keep. I used to use some tools from teletronics but the new version isn't nearly as good. If you just need something that'll give you a ballpark reading they do work better than nothing.
