NMT signals contain complex groupings of digital data that vary in format and
function, depending on a number of system operating needs.
To be able to test NMT radios using these screens, you must be familiar with the
theory, applications, and specifications of the NMT systems. The large volume of
information required to explain the NMT system is beyond the scope of this
manual.
Documents explaining the structure and specifications for the different NMT
standards should be obtained from the radio communications regulatory agency of
the appropriate country.
