2.9 4-way-Splitter
The 4-way-Splitter provides the RF-signal to the RF modules. It splits up the signal from the
Receiver and provides four equal RF outputs with an attenuation of 10 dB for the RF
modules. It is mounted underneath the Optical Transceiver and can be seen only, if the
Transceiver is dismounted.

2.10 Measuring aids
With the built-in RF probe test signals can be applied or detected. The duplexer is equipped
with a probe which provides a coupling factor of 30 dB. This facilitates measurements under
all operational conditions, while an antenna or a dummy load may be connected.
