Table 212 describes the other parameters that can be displayed in the Channel Metrics Trend output. Click the

Parameter Description
Band Radio band displayed in this graph (2.4 GHz or 5 GHz).
Show Trend for Last By default, the Channel Quality Trend chart shows channel quality or channel availability for
the past 10 minutes. To view data for a different time range, click the Show Trend for Last
drop-down list and select one of the following options:
l 10 minutes
l 30 minutes
l 1 hour
Channel numbering For spectrum monitors using the 5 GHz radio band, select either 20 MHz or 40 MHz channel
numbering to identify a channel numbering scheme for the graph.
NOTE: This parameter is not configurable for graphs created by hybrid APs or spectrum
monitor radios that use the 2.4 GHz radio band. A hybrid AP on a 20 MHz channel sees 40 MHz
Wi-Fi data as non-Wi-Fi data.
Show Lines for These
Channels
The Channel Quality Trend chart for a spectrum monitor can display channel quality, channel
availability or channel utilization values for up to five different channels on the selected radio
band. Charts for hybrid APs can display data for the one channel monitored by that hybrid AP
radio.
To choose which type of data each line should represent on a chart for a spectrum monitor,
click the channel number drop-down list and select a channel within the radio band, then
click the second drop-down list and select either Channel Quality, or Channel Availability.
Select the checkbox beside each channel entry to show that information on the chart, or
unselect the checkbox to hide that information.
