4-4 TONE REMOTE TESTING
The tone remote function allows the analyzer to
generate the required function tones and timing
for tone controlled equipment. Specific tones are
sent to remote equipment via phone lines that are
connected to remotes or control consoles. Base
stations and repeaters are examples of equipment
using tone control commands. For example, tone
commands can command transmitters and
receivers to change frequencies or disable PL.
The analyzer can simulate the tones and appear to
the base station or repeater as a console or desk
remote.
The most common use for the tone remote feature
is commanding tone remote bases in order to
measure all the main transmitter parameters. The
main parameters would be power, frequency and
system deviation. Without this capability, a
technician must rely on personnel at the remote
console or carry a tone remote to the base site.
This can be impractical and time consuming.
