3.6 Wi-Fi Spectrum Analysis
NOTE: The spectral analyzer is a licensable feature and requires the newer T5300 hardware to
operate. For more information on hardware models, see About hardware models and variations
on page 1-5.
The Wi-Fi Spectrum Analysis tool provides a graph of measured power levels across a set frequency
range within the Wi-Fi spectrum. Its general operation is similar to any common spectral analyzer. In
cases where Wi-Fi quality is poor, the analyzer can help determine whether the spectrum around the
applicable channel has excessive activity and likewise help determine a better channel for connectivity.
The following figure is a sample analysis of the 2.4 GHz band, where the frequencies around channels
10-12 show a significant amount of activity. If connectivity is poor in this channel range, the graph
suggests that a lower channel might be less congested.

The Display menu (F1) provides the following commands:
Packet Retries Within the sample for the device, the total number of Wi-Fi packets sent as a
retransmission. Due to the uncertain nature of a wireless connection, each packet
must be acknowledged by the receiver, otherwise a retransmission occurs. The
unit uses the retransmission flag in these packets to produce this count.
