Manually Testing MPT 1327 Radios
MPT 1327 signals contain complex groupings of digital data that vary in format
and function, depending on a number of system operating parameters.
To be able to test MPT 1327 radios using this screen, you must be familiar with
the theory, applications, and specifications of the MPT 1327 system. You must
also be familiar with IBASIC programming, since some of the required signaling
commands are not available on the encoder screen; they must be sent using
IBASIC commands. (See
"Undisplayed Controls" on page 407
.)
The large volume of information required to explain the MPT 1327 system is
beyond the scope of this manual. Documents explaining the structure and
specifications of this system should be obtained from the radio communications
regulatory agency of the appropriate country.
Using Automated Test Software
The HP 11807A Option 012 MPT 1327 Trunked Radio Tests software provides
comprehensive automated tests of MPT 1327 radios. All Test Set RF, AF, and
Encoder/Decoder controls are automatically set, requiring minimal operator
inputs.
You can choose any combination of tests, from full transmitter and receiver
testing, to a single test. The software is shipped on a memory card that inserts
directly into your Test Set, and comes with complete documentation and a blank
SRAM memory card for storing your test procedures and test data.
