Calibration Test Unit
(CTU)
The CTU is used to configure and test the base station. The same CTU is
used for TB8000 and TB9000 base station equipment, so only some of the
features on the CTU apply to the TB7100 base station. The CTU adaptor
is plugged into the system connector of the CTU. The CTU cable is
plugged into the system connector of the base station.
For more information on the CTU refer to the TBA0STU/TBA0STP
Calibration and Test Unit Operation Manual (MBA-00013-xx).

adaptor cable to the system connector of the base station.
Note
Connections between the CTU and the test equipment will vary
