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.
