Colors in the display have the following meanings:
◦ Green bars show the most recent measurements.
◦ Yellow ticks show the maximum measurements from the current spectrum
analysis session.
◦ Red ticks show measurements of −40 dBm or stronger.
21.1.3 Tabular Spectrum Analyzer Display
An SM/BHS displays the tabular spectrum analyzer if either
◦ the module operates on a Canopy system release that is earlier than
Release 4.2.
◦ the module is not calibrated for received power. This is the case if the Status
page reports received power in units of only RSSI. Earlier modules were not
calibrated as shipped.
You can calibrate an uncalibrated module. If you wish to do so (in lieu of continuing with
the tabular Spectrum Analyzer page), download the required instructions and data from
http://www.canopywireless.com/calibrate.php
.

NOTE:
Although calibration improves the measurement of received power,
calibration has no effect on reception, transmission, or other aspects of
performance.
An example of the tabular Spectrum Analyzer web page is shown in Figure 115.
