Description
1
Sensor
(Various
versions)
RF-detectors
Temp-
Detector
A monitoring Sensor is mounted at the input of each antenna
and power splitter/divider. A RF-detector is mounted on
existing directional couplers with N-/SMA-connector. From the
Sensor/RF-detector inputs, the following statements can be
made,
actual value and trend curve
:
Return Loss/VSWR at monitoring point
PTx value, with indication of status of feeding part
PRx value, with indication of status of load
Transmission/Reflected Power in Watt related to the Tx
and Rx Value
Temperature at
indoor
monitoring points

Junction Box
(Various
versions)
JB
The sensors/RF-/Temp.-detectors are connected with a jumper
cable to the JB; the JB is available in different versions. The
JB can work in a daisy chain mode, max
16 JB can be
connected
to one DL/PDL. The JB connects with a hybrid
cable (plastic coated fibre/copper for the outdoor version JB
3.x) or directly with electrical RS485 interface to the DL/PDL
4.x (daisy chain works also for the indoor version).

DL/PDL The DL/PDL has one Hybrid connector and one electrical RS
485 interface, to connect with the JBs. The PDL has on top
local RF-interfaces and is available in various versions. The
DL/PDL is recording all measurement results. Also the DL/PDL
has a web server built in. With a standard browser the
Monitoring System is configured, the alarms and the measured
values/trend curves are displayed. The DL/PDL connects to
the Ethernet and the Analytics-SW. Optionally a GSM module
