Eric, These are only my opinions and I could be wrong but I do not recommend the Yellowjacket even though it has a spectrum analyzer function because:
1. You are paying a lot for the protocol analysis part of the instrument. A real spectrum analyzer works at ISO layer 1 - the wireless layer. It is not a protocol analyzer. Interference reduction (the primary reason to use a spectrum analyzer) doesn't care about protocol - it's RF energy, pure and simple. 2. The Yellowjacket SA function is just too limited. It doesn't go outside of the band where high-powered out-of-band interference may be lurking. The Yellowjacket is "sexy" but I think that will wear off and many buyers will wish that they had spent their money on a "real" - a more fully-functioned and versatile SA. jack ericblack wrote: > Hi All, > > Might Jack or anyone else have anything to say about the Yellow Jacket > "Spectrum Analyzers" ?
