Figure 5-4: Device Detected
To create a custom device classification signature:
1) First, wait until you see a distinct pattern for the device on the Max or Current Line of the
FFT graph. By default, the visibility of Current Line is not enabled on the Real Time FFT
chart. The user can enable it from the chart configuration window.
2) Click the Add Custom Device Classification button (this is located at the top left of the
FFT graph, see Figure 5-4).
3) The slider bar on top of the Custom Device Window can be used to move forward or
backward on the frames to capture a perfect pattern. This slider is in sync with the Instant
Playback data with a maximum of 2 minutes worth of data. The slider bar is enabled only
for the signature which is currently being defined. To get the most accuracy out of the
custom signature feature, the user should select only the portion of the band which
contains the interferer’s distinct pattern. See Figure 5-5.
