RT-9000 B
7.3.3 EQUIPMENT SET-UP
This section addresses those features and functions that are either of secondary operational importance or
need be accomplished only infrequently, usually at the time of commissioning.
7.3.3.1 BITE (Built-In-Test-Equipment)
The RT-9000 B is equipped with self-diagnostic routines that allow the operator to verify that all Modules are
functioning correctly. If a fault is found, these test routines will help identify which Module is faulty. The BITE
function operates independently of any mode in which the equipment was operating before the BITE function
was enabled.
The RT-9000 B BITE function has two (2) levels of test routines. The first level checks the operation of RT-
9000 B Primary Modules that provide basic service functions to the rest of the unit (Power Supply, CPU, etc.)
This test routine is called General BITE. The second level is composed of specialized test routines that check
either the Receiver or Transmitter modules. If the system contains an Antenna Coupler, a separate test
routine to verify Antenna Coupler operation is included. These specialized second level BITE tests are called
Receive BITE (‘RX-BITE’), Transmit BITE (‘TX-BITE’) and Coupler BITE (’CU-BITE’).
When entering BITE mode from the main menu, the User will first encounter the General BITE test routine.
General BITE must be executed and passed before the second level BITE tests will become available. After
General BITE is passed, the Feature Menu Display will change and provide Receive BITE (‘RX-BITE’) and
Transmit BITE (‘TX-BITE’) choices. If the system has an Antenna Coupler, a Coupler BITE (‘CU-BITE’) choice
will be available. An ‘END’ choice is present If the User wishes to exit BITE mode at this point. This allows the
User to return to the main menu and resume normal operation.
Transmit BITE primarily tests RT-9000 B Transmitter modules but also briefly tests the Antenna System.
Antenna System condition is an important part of the overall radio system performance. If faulty, the Antenna
can adversely other station equipment and performance. This is particularly true for Transmit related
operations. More detailed information about Antenna related testing is covered later in section 7.3.3.1.3
Transmit BITE.
7.3.3.1.1 General BITE
Depress the Feature Menu ‘MORE’ key from the main menu successively until the Feature Menu shown in
Figure 7.3.3.1 appears. Unless otherwise noted, all text in section 7.3.3.1 refers to Figure 7.3.3.1.
