Chanalyzer 5 offers several different Wi-Spy modes that can either be enabled in the Wi-Spy menu, or by connecting multiple Wi-Spy adapters.
Comparison of Wi-Spy Modes
|Mode||Required Wi-Spy Hardware||Mode||Sweep Speed|
|Full 2.4 GHz Band||2.4x or DBx||2.4 GHz Sweeps||Full|
|Full 5 GHz Band||DBx||5 GHz Sweeps||Full|
|Dual-Band||DBx||Alternating 2.4 and 5 GHz Sweeps|
|*Double Rainbow||DBx + 2.4x or DBx + DBx (Two devices)||Simultaneous 2.4 and 5 GHz Sweeps||Full|
*Double Rainbow Mode
Two Wi-Spy devices can be connected to Chanalyzer to enable Double Rainbow Mode (Dual Wi-Spy Mode), in which each Wi-Spy will be dedicated to a specific band. This will allow Chanalyzer to perform simultaneous 2.5 and 5 GHz spectrum analysis.
From a cost perspective, the optimal hardware combination is a Wi-Spy 2.4x and a Wi-Spy DBx, but two Wi-Spy DBx's can be used in Dual Wi-Spy Mode.
