WiFi Graph Options
AirMagnet Spectrum XT has the capability to capture live WiFi data in real time and display
them in charts or tables. This feature is a great complement to AirMagnet Spectrum XT’s
spectrum analysis capability, offering a complete, one-stop solution for detecting and
troubleshooting various performance issues in the wireless network.
However, it must be noted that an AirMagnet-supported external wireless network adapter is
required in order for AirMagnet Spectrum XT to capture live WiFi data in the network and
presents them on its user interface. This means that the user must have both the AirMagnet
Spectrum USB adapter and a supported external wireless network adapter running
simultaneously on the same PC. Without a supported wireless network adapter, the
application will be unable to capture live WiFi data in the network and presents them on its
user interface.
For a list of supported wireless network adapters, refer to “Supported Wireless Network
Adapters” on page 8.
All WiFi graphs are listed in the WiFi Graphs list menu, which is available in all individual
graphs.
