Re: [WISPA] Diagnosing interference
Hiya Dustin, I have an Advantest. 9k to 8g. Very nice. When I get another one I'm gonna look for a couple of things. I like the color lcd display, but it needs to be brighter for use in the sun. I'd get one that's got fewer buttons on it. I don't need to decode cell phone calls. Portable with battery backup would be cool. I LOVE the Anritsu units that EC carries. Too bad that the small ones need the frequency converters for our use. I also need to get some more of the super flexible 10' lmr 400 type cable.

RE: [WISPA] Diagnosing interference
Hey Marlon, Here is my anritsu list. Love it, with all the upgrades I can't remember the cost but it was in the same ballpark. 1. 3.0-6 gig attachment is a little annoying because you have to take it on and off. 2. Battery life is Ok, like the care charger, Big brick to lug around on the AC cord. 3. Use in sunlight is great, Buttons work really well and placed in good position. Don't like the interface to label saved sweeps. Kind of like using your cell phone to txt someone. Big pain in the ass. 4. Resolution is really good 5. It's very flexible as far as software options. 6. support is very good. I had lots of questions when we got our first one. They answered them all and did some guiding over the phone. 7. Yearly recalibration is recommended. 8. Durable and light weight. Still need a backpact to carry all of your antenna's around. 9. I've seen better PC software on other units but it's not too bad. Some of the PC based stuff seems better for generic long term stuff but not high resolution scans. Dustin -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marlon K.

Mike, I use a Motorola Canopy 2.4 SM to check for interference issues.

Spectran? Are you talking about the software for a PC sound card? That's not going to do what you want, for sure! There really isn't a cheap solution. What wireless gear do you use? If it has an external antenna input you should be able to attach a very high gain antenna (and an attenuator) and go on a real live fox hunt You can rent a spectrum analyzer as well, but it is pricey!
