6 ALIGNMENT AND TESTING
The SB2025NT test and alignment procedures are divided into two main sections. The first section
is a transceiver level procedure, which assumes that the radio is fitted with working modules. The
second section contains the individual module test procedures.

LIGNMENT
This section explains how to setup, calibrate and align the complete SB2025NT Base Station. A
number of procedures are required to fully initialise the SB2025NT. The following test equipment
will be needed:
PC with MxTools and ET (SB2025 Base Station Programming Utilities).
RF Test Set (HP 8920) or equivalent.
Oscilloscope.
RF Power Meter (Watts).
RF Signal Generator.
Multimeter.
+13.8 V DC Power Supply
The order of some, but not all, of the procedures is important to ensure correct setup of the radio.
The order of the procedures as described is recommended and those that are critical are
mentioned. If the radio has been previously setup and the user intends to recalibrate and align the
radio then Sections 6.1.1, 6.1.2 and 6.1.3 can be ignored as the model number, serial number,
configuration and channel information will have already been loaded.
For any procedure that involves the use of the MxTools programming utility, further information and
assistance can be found in the relevant part of the MxTools Help menu/screens.
6.1.1 Sending Model Number and Serial Number to the Radio
The model number is entered or updated using MxTools. To edit the model number, carry out the
following:
1. On the MxTools main screen, on the menu bar, select ‘Setup’ > ‘Radio Model Number’. The
Radio Model Number dialogue box will be displayed.
2. On the Radio Model Number dialogue box, enter the model number, according to the
configuration of the radio.
3. Once the radio Model Number information has been completed, select the ‘Send’ button to
send the information to the radio.
4. To return to the MxTools main screen, select the ‘Exit’ button.
Notes:
(i).
The model number should not be altered unless the hardware within the SB2025 base
station is changed. For example, a module is changed or an option has been added to
the radio.
(ii).
The serial number cannot be altered, as this is factory set.
