2.3.3 Antenna monitoring
As shown in the figure, the multiple numbers of service antennas can be used for PSR installed together with
couplers or dividers. However, normal RF power may not be radiated by the service antennas when there’s a
problem with service antenna itself, or due to the poor connection between antenna and RF cable, or other
similar kinds of RF mismatching issues.
To implement antenna monitoring, the service antenna has a specially designed power monitoring circuit inside,
which provides continuous monitoring of antenna power. If a problem happens on power radiation, it is reported
to the CPU through the Bluetooth chip to enable further follow-up action.
Figure 2 - 13 Concept of antenna monitoring
Monitoring circuit reports antenna status to CPU periodically and the user can monitor the individual service
status by using WEB UI.
2.3.4 Single / Dual band
There are 3 independent bands for PSR, and could work as a single band PSR by enabling either one the band.
Service band can be extended to dual band or full band by choosing dual band option. It is necessary to run
‘install wizard’ again with dual band license key to upgrade PSR as a dual band device.
