TB9100 Calibration Software User’s Manual Basic Tasks 1
Basic Tasks
The TB9100 Calibration Software is a Windows-based software program that
allows you to adjust the switching ranges of Tait TB9100 base stations (both
receiver and transmitter), and to flatten the receiver response across that
switching range.
The Calibration Software is also used to calibrate the reciter, the PA, and the
PMU after servicing.
Using the TB9100 Calibration Software
When you start the Calibration Software, the main program window appears.
The main program window has four tabs. The Calibration Wizards displayed
on each tab are only visible once you are connected to the reciter or the base
station.
When the Calibration Software is connected to the reciter or base station, you
can view further details (such as module number, type, serial number, band, and
hardware version) about the currently selected module by clicking Show
Details.

TB9100 Calibration Software User’s Manual Basic Tasks 3
Equipment Required
You need the following equipment for field calibration:
■ Calibration and Test Unit (CTU, order code TBA0STU), which comes
complete with the cables you will need for connection to the reciter/PA and
the PC. For more information about the CTU, please refer to the CTU
Operation Manual.
■ Tool kit (order code TBA0ST2) which comprises tuning tools and the
required screwdrivers in a tool pouch. The ceramic-tipped Murata tuning
tool is used for most procedures, but the metal-tipped Johanson 8777 tuning
tool with its narrower blade is needed for tuning the front end of H-band
and K-band receivers.
■ 10-30 V DC power supply (if the PMU does not have a 12 V or 24 V
auxiliary power supply module)
■ RS-232 cable
■ RF attenuator (optional – depends on the setup)
You may also need the following additional equipment:
■ Frequency counter with an accuracy of 50 parts per billion or better and a
current calibration certificate
■ Modulation meter (the calibration software supports the Agilent 8920, the
Aeroflex IFR2975, and the R & S CMS54)
■ RF signal source
■ AC millivoltmeter (one with a differential input may be required for
“Calibrating the Balanced Line” on page 20)
Refer to the individual procedures for equipment setup diagrams.
Calibration Overview
Any calibration process creates digital values and a calibration date, which are
stored in the base station. The CSS can display the date of the last calibration.
Many calibration procedures initially clear the stored digital values. If you do
not complete the procedure or the stored digital values are outside acceptable
limits, the module is left uncalibrated. An uncalibrated reciter cannot be put
into Run mode. An uncalibrated PA generates a calibration invalid alarm.
If the procedure you are performing requires access to tuning holes, you need
to remove the reciter from the subrack and connect to it via the CTU.
The following tables summarize, for each procedure, whether or not you need
to remove the reciter from the subrack, and what equipment (in addition to a
PC with the Calibration Software) you will need.
4 Basic Tasks © Tait Electronics Limited February 2007
Field Calibration
The following procedures can be carried out in the field.
In addition, the following procedures should be carried out if the base station
fails a modulation fidelity test.
Service Center Calibration
The following procedures may need to be carried out after a module has been
serviced. They are in addition to the field procedures listed above.
Note: Replacing or repairing a board module may mean that the
module’s product code, product type (frequency band), serial
number, and/or hardware version need to be re-entered or altered.
To do this, your Calibration Software needs a dongle. The Service Manual
indicates when a module detail needs re-entering or altering.

Receive-Only Base Station Calibration
The reciter in a TB9100 receive-only base station differs only in the absence of
a Transmit enable feature license. (The TB8100 receive-only reciter is a
hardware variant with no transmit capability.) Accordingly, the calibration
software reports the reciter type as standard. You need to carry out receiverrelated calibration procedures. Procedures related to the exciter can be carried
out but serve no purpose.
P25 Console Gateway Calibration
The current P25 Console Gateway is effectively a reciter without feature
licenses for transmitting and receiving. Accordingly, the calibration software
reports the reciter type as standard. You need to carry out procedures that relate
to the analog line. Procedures related to the exciter and receiver can be carried
out but serve no purpose.
Selecting the Communications Port
Before you connect to a base station, you should first define the
communications (COM) port that you want to use.
To select the COM port
1. Select Tools > Options.
2. Select the port that you want to use from the COM Port list.
Note: The available COM ports are detected by the program and
appear in the list.
3. Click OK.
The COM port you selected is now shown on the status bar.

Setting Up the Equipment
For field calibration procedures, you need to remove the reciter from the
subrack to gain access to tuning holes. If a CTU is required for one procedure,
it is probably easiest to use it for all your procedures. If it is not required, you
can connect the PC directly to the reciter.
To set up the equipment
1. Remove the reciter from the subrack, following the instructions in the
Installation and Operation Manual. (Note that for some service center
procedures, the reciter can be left in the subrack.)
2. Connect the reciter and the PC to the CTU according to the diagram
below.
■ Connect the reciter’s analog RJ-45 socket (labeled AUD) to the CTU’s
RJ-45 using the RJ45 cable
■ Connect the reciter’s 9-way serial connector (labeled DIG) to the CTU’s
9-way male connector using the 9-way cable.
■ Connect your PC to the CTU by plugging an RS-232 cable into the 9-
way serial port labeled 10101.
(If you are not connecting via the CTU, connect the PC to DIG using the
RS-232 cable. No other connections are required.)
Note: Tait recommends that you disable the PC’s hardware
handshaking. The DIG connector is used for digital I/O as well as
for RS-232 and this could interfere with the handshaking.
Alternatively, use a special DB9 cable that has only three connectors (for pins
2, 3, and 5).
3. Connect the CTU to the 10-30V DC power supply using the power cable
supplied. If the base station’s PMU has a 12 V or 24 V auxiliary power
output, you can use this as the power supply. A connector is supplied with
the CTU. The reciter must also be supplied with power, but do not power
it up yet.
