System Manual 2600.5423.02 ─ 01
With some dummy antennas that have coolant monitoring and overtemperature moni-
toring, the monitoring equipment can be connected to the transmitter. The main RF carrier
loop X41.1 and X41.2 on the CAN bus adapter or exciter switch can be used here as a
temporary measure (e.g. while the unit is being put into operation).
1. To connect the main RF carrier loop, use the inserted jumper plug and remove the
jumper.
2. Connect the monitoring cable in place of the jumper.
If you are using an RF patch panel that allows you to switch between the antenna and
dummy antenna by means of an RF bridging link (permanent installation), attach the
dummy antenna monitoring unit to the standby RF carrier loop (X41.1 and X41.2 with
CAN bus adapter, X41.3 and X41.4 with exciter switch). For more details, see 
chap-
ter 3.2.9, "Installing the RF Loop"
, on page 62.
3.2.8 Installing R&S TCE900 Customer Interfaces
The various versions of the TCE900 are already integrated into the rack with the delivery
of a transmitter. Installation is limited to wiring at the device's customer interfaces. Which
cables need to be connected depends on the transmitter configuration, the device version
and the custom requirements.
The cables used to provide ASI, 10MHz, PPS and GPS signals, should be double shiel-
ded.
IP and Ethernet connections should use class CAT6 cables should be used.
Please refer to the system circuit diagram for the system wiring applicable to your system.
The following steps are required to install a R&S TCE900.
1. Insert the R&S TCE900 into the TCE pull
‑out frame without canting it (only one run-
ner) and carefully push the unit back to the front stop.
2. Fasten the R&S TCE900 to the TCE pull
‑out frame using the two knurled screws.
3. Connect the cable in accordance with the wiring diagram and target designation.
4. Complete the TCE pull
‑out frame with the front panel
a) To connect the Tx Control or Exciter A (for single drive) and TSP, plug the control
cable into the mini USB socket on the TSP900.
b) Hook the eyelets on the rear of the front panel into the hooks on the TCE pull-out
frame and press the front panel down as far as it will go.
c) Retighten the front panel to the sides of the TCE pull-out frame using four screws
(size 20 Torx screwdriver).
5. Slide the TCE pull-out frame into the rack.
