wireless network. This mode is available on the Tools menu.
Twothings to note about t he channel scan monitor:

dialog(see page 6 o f thism anual).
• When Observer is scanning channels, the other modes (such as Top
Talkers,Access Point S tatitistics) will no longer be able to present
completeview of the network, as Observer’s data sample is limited to the
current channel being scanned. Therefore, you should only use the
Channel Scan monitor by itself.
