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.
