8.3.7.9 Viewing Historic Spectrum Management Metrics
Spectrum Management allows the system administrator to view the results of previous measure-
ment quantization periods. Holding down the shift key and clicking the appropriate channel on the
local channel spectrum plots activates this feature. This feature is available on both the master
and slave web page.
Figure 63 shows an example time series plot. A time series plot displays the previous 132 measure-
ment quantization periods. If the PTP 500 Series Bridge has not been running for 132 quantization
periods then only the number of measurement quantization periods that are available are displayed.

8.3.8 Spectrum Management (Fixed Frequency)

The PTP 500 Series Bridge software allows a user to optionally fix transmit and receive frequencies
for a wireless link. Once configured, the spectrum management software will not attempt to move
the wireless link to a channel with lower co and adjacent channel interference. Therefore this mode
of operation is only recommended for deployments where the installer has a good understanding
the prevailing interference environment. (See
must also be taken to ensure that the frequency allocations at each end of the link are compatible.
To help the user when identifying the mode of operation Spectrum Management uses two visual
Figure
cues. See
The main page title identifies the mode of operation using the "Fixed Frequency Mode" postfix
and the selected channels are identified by a red capital 'F'.
