Channels by Retry/CRC
The Channels by Retry/CRC graph allows the user to quickly assess which channels are
experiencing high levels of Retry or CRC packets.
Auto Pattern Detection and Custom Device Classification
Auto Pattern Detection and Custom Device Classification enables users to identify, classify,
and analyze interferers beyond those devices included in the software package.
• Auto Pattern Detection: The system identifies and lists persistent RF patterns that do
not match its database of interferers. The user may name and save the pattern in order
to have it show up as a named interferer in the future when that pattern is detected.
• Custom Device Classification: The user may create a custom signature of an RF pat-
tern in order to have it show up as a named interferer in the future when that pattern
is detected.
Find Device Tool
The Find Device tool enables the user to find any device (WiFi or non-WiFi) that the
application has detected. You can launch the Find Device screen by clicking the Find Device
button. Once on the Find Device screen, you can select the device of interest and use the
application to physically locate the device on the network. The screen shows in real time the
signal strength (if the device in question is a non-WiFi device) or signal strength and noise
level (if it is a WiFi device). You can also turn on the audio feature to assist in locating the
device: the closer you approach the device, the louder it ticks.
Instant Playback of Capture Data
The instant playback feature allows the user to revisit something they have noticed for the last
two minutes on the live screen. It is very useful when the user wants to take a closer look at
what has caught their attention at the first glance. The user can save to a file the data that they
revisited and play back the data within the application by opening that file. To switch to
instant playback mode, simply click the Switch to Instant Playback button on the toolbar.
Recording Live Capture Data
This feature allows the user to record live capture data the application captures to the hard
drive of the PC. The user can interrupt the recording at any time by clicking and save the
recorded data to a .amt file. The length of the recording depends on the Max Live Capture
Streaming File Size [MB] the user has configured. The application will stop recording once
the limit has been reached. Upon completion of the recording, the user will be prompted to
save the recorded data.
Auto Recording Capture Data
By default, when lauching AirMagnet Spectrum XT, data is automatically recorded. The user
may stop the data recording by clicking on the Stop button on the toolbar. To switch to instant
playback mode, simply click the Switch to Instant Playback button on the toolbar.
