The Wi-Spy 2.4x Spectrum Analyzer is an updated version of the old geek favourite network sniffing tool. It’s got improved this and increased that – you don’t really want to know, do you? – and offers recording and playback of of data traces as well as pretty graphs. Ooh pretty graphs. $399.99.
The hardware has been redesigned to increase the frequency and amplitude resolution with an added reverse-polarity SMA adapter. Wi-Spy 2.4x is packaged with a powerful little antenna, so it’s good from the start but it’s also a snap to screw-on any RP-SMA antenna you choose. The Chanalyzer software has been upgraded to version 2.1, which takes full advantage of the higher resolution with improved graphics and an even friendlier user interface.
