1Introduction
The base station calibration and test unit (CTU) is designed to make it easier
to connect a Tait base station to standard test equipment, and to a PC
running the appropriate programming and calibration software. The CTU
can be used with TB7100, TB8100 and TB9100 base stations, and comes
with a selection of connection cables, tuning tools and other accessories
(refer to “Appendix A - CTU Accessories” on page 35).
Note Some features of the CTU are used with only one base station,
while others serve different functions with different base stations.
Any differences in function are explained in each chapter.
This manual describes both the TBA0STU and TBA0STP CTUs. The
only difference between the units is that the TBA0STP was not supplied
with the TB7100 CTU adaptor board. For information on the earlier
TBA0ST1 CTU which was introduced with the TB8100 base station, refer
to TN-778.

2 Modification History
This chapter provides details about any production modifications made to
the CTU that may affect its performance, or the way in which it interacts
with the TB7100, TB8100 or TB9100 base stations.
AC Coupled
Unbalanced Audio
Input
The unbalanced input on the CTU was changed from DC to AC coupled
in August 2005. This modification (fitting a capacitor) was necessary
because the unbalanced input on TB8100 TaitNet and TaitNet RS-232
system interface boards was changed at that time from AC to DC coupled.
This change was made for paging, and the version of these boards was
changed from 0 to 1. If your reciter is fitted with a version 1 TaitNet or
TaitNet RS-232 board, you must use a CTU that is AC coupled. If the
CTU and system interface board are both DC coupled, and the test
equipment is not AC coupled, the DC signal will directly pull the modulator
carrier frequency.
CTUs with the serial number 18012507 and higher incorporate the change
on the PCB, but earlier CTUs must be modified as described in TN-1082.
To check if your CTU has been modified, use a multimeter to check the
continuity between the centre pin of the unbalanced input BNC connector
(UB INPUT) and pin 6 of the 15-way system interface connector (or pin 5
of the 25-way connector). An open circuit indicates the capacitor is fitted,
a short circuit indicates the capacitor is not fitted.
To check the version of a system interface board, run the Service Kit and
select Monitor > Module Details > Reciter. In the Versions area, the
System Interface field displays the version number.

3 Using the CTU with a TB7100
The CTU provides a selection of input and output connectors that allow the
TB7100 base station to be connected to standard test equipment. These
inputs, outputs and associated controls are identified in Figure 3.1 on
page 12, and their functions are explained in the paragraphs which follow.
Some items are not used with the TB7100, and others serve one function
with the TB7100 and another with the TB8100 or TB9100. Any
differences in function are described in the table that accompanies
Figure 3.1. A block diagram of the CTU is provided in Figure B.1 on
page 40.
The CTU is designed to make it easier to tune or calibrate TB7100
modules. It also allows a user to monitor and control the inputs and outputs
available on the TB7100 system interface connector.
Note Digital/programming input switch 6 is used to control Rx Inhibit
in the TB7100. Setting this switch to active will prevent any audio
output from the base station. Be careful not to set this switch by
accident.
Figure 3.2 on page 16 shows a typical connection setup between the CTU
and a TB7100 base station. Refer to the TB7100 Calibration Application
online Help for details on tuning and calibrating TB7100 modules. Refer
also to the TB7100 Installation and Operation Manual for information on
using the CTU to set up the TB7100 for various modes of operation.
