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.

TBA0STU/TBA0STP CTU Operation Manual Modification History 9
© Tait Electronics Limited September 2005
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.

IOIOI Not used with TB7100.
POWER The POWER LED is lit when the CTU is powered up. The TB7100
system interface provides power to the CTU over the 25-way system
interface connector 1! (see also Figure 3.2 on page 16). This supply powers
the noise source, speaker, LEDs, and RS-232 communications.
Connecting power directly to the DC input connector 2@ on the CTU is
unnecessary, but will not damage the CTU.
Note You do not need to provide power to the CTU at all in order to
make audio level measurements or to use the digital inputs and
outputs. Lack of power will not affect these interfaces.
NOISE Not used with TB7100.
LINE INPUT The CTU makes audio at this input available to the TB7100 transmitter (it
connects LINE INPUT to the balanced line input on the system interface
connectors).
UNBALANCED/OFF/
BALANCED This switch directs either the balanced or unbalanced receiver output audio
to the CTU speaker. When set to “OFF”, no audio is present on the
speaker.
UB INPUT This input is connected to the unbalanced line input on the system interface
connectors.
UB OUTPUT This output is connected to the unbalanced line output on the system
interface connectors. Audio on this line can be monitored on the CTU
speaker.
LINE OUTPUT The CTU makes audio from the TB7100 receiver available on this
connector (it connects LINE OUTPUT to the balanced line output on the
system interface connector). LINE OUTPUT is connected directly to pins
1 & 2 on the connector (i.e. it is not grounded). The audio on LINE
OUTPUT can be monitored on the CTU speaker.
600ΩLOAD This switch connects or disconnects the 600Ωload across the balanced
LINE OUTPUT. This allows the output to be terminated correctly for
calibration procedures. Turn the switch on if the LINE OUTPUT is not
otherwise terminated.
SYSTEM INTERFACE Not used with TB7100.
SYSTEM INTERFACE The 25-way connector is used with the TB7100 CTU adaptor board to
connect to the 25-way connector on the rear of the TB7100.

DIGITAL/
PROGRAMMING
INPUTS
These switches let you set the digital inputs into the TB7100 high or low,
and are connected to the digital inputs on the system interface connector.
Switches 1 to 4 can be used for channel selection, and switch 6 is used to
control Rx Inhibit. The remaining switches are not used with the TB7100.
The active state of the digital inputs is defined by the setting in the
Programming Application software (Channel Setup > Programmable I/O >
Digital tab: AUX_GPI1, AUX_GPI2, AUX_GPI3, AUX_GPIO4). The
default setting is non-inverted: 0 = active, 1 = inactive.
Speaker The CTU is fitted with a 0.5W 16Ωspeaker. Audio from LINE OUTPUT
or UB OUTPUT can be connected to this speaker.
VOLUME This controls the volume of the speaker. Rotate clockwise to increase the
volume, and anticlockwise to decrease the volume.
RSSI This output is used to monitor the RSSI output from the 25-way system
interface connector.
DIGITAL OUTPUTS Not used with TB7100.
GND This banana socket can be used as ground with RX GATE, TX KEY and
RSSI. It is connected to the CTU and system interface connector ground.
TX RELAY This output is connected to the Tx Relay output on the 25-way system
interface connector. The LED is lit when the output is activated.
TX KEY Switch Set this switch to “ON” to key the transmitter. When the switch is in the
“OFF” position, applying a signal to the TX KEY banana socket will
control the state of the transmitter.
TX KEY socket Ground this input to key the transmitter. Alternatively, turn on the TX KEY
switch (1().
RX GATE This output is connected to the Rx Gate output on the system interface
connectors. The adjacent LED is lit when the receiver gate is open.

The TB7100 CTU
Adaptor Board You must use the TB7100 CTU adaptor board when connecting a TB7100
base station to the CTU. The CTU adaptor board plugs into the 25-way
system interface connector on the CTU. It is designed to make the I/O of
the TB7100 system interface compatible with the I/O of the CTU system
interface. The LEDs and test points on the adaptor board are described
below.
Figure 3.3 LEDs and test points on the TB7100 CTU adaptor board

4 Using the CTU with a TB8100
The CTU provides a selection of input and output connectors that allow the
TB8100 base station to be connected to standard test equipment, and also
to a PC running the Service Kit or Calibration Kit software. These inputs,
outputs and associated controls are identified in Figure 4.1 on page 20, and
their functions are explained in the paragraphs which follow. Some items
are not used with the TB8100, and others serve one function with the
TB8100 and another with the TB7100 or TB9100. Any differences in
function are described in the table that accompanies Figure 4.1. A block
diagram of the CTU is provided in Figure B.1 on page 40.
The CTU is designed to make it easier to program, tune or calibrate
TB8100 modules. It also allows a user to monitor and control the inputs
and outputs available on the reciter’s system interface connector.
Figure 4.3 on page 26 shows a typical connection setup between the CTU
and a TB8100 base station. Refer to the TB8100 Calibration Kit
documentation for details on how to use the CTU for tuning and calibrating
TB8100 modules.
Important Do not power the CTU from a PMU fitted with a 48V
auxiliary power supply board. The maximum supply volt-
age for the CTU is 32VDC. Use either a PMU 12VDC or
24VDC auxiliary output, or an external power supply.
Note that the auxiliary output can be supplied to the CTU
via the system interface connector on the reciter if the aux-
iliary DC power cable is fitted, as well as via a direct con-
nection to the PMU auxiliary output.
