Project 25 Conventional Test Option

Feature Description Benefits

Voice Mode System Testing

This feature provides Project 25 compatible

FDMA Digital C4FM modulation and demodula-

tion with vocoding and embedded data testing.

Generate and monitor modes support actual

functional voice testing. Within the voice

mode, embedded data can be encoded and

decoded for either subscriber or fixed site

radio equipment.

This feature allows you to verify operation and

system compatibility under actual operating

conditions for increased confidence of proper

system performance.

Bit Error Rate (BER) Testing

BER testing can be performed on radios that

support BER test capability. The R2670/R2625

in Project 25-mode can generate RF transmis-

sions modulated with either a 1011Hz tone test

pattern or a calibration test pattern (generates

5% BER) for UUT BER measurement. The units

will compute a BER when a 1011 Hz tone test

pattern is received.

This testing provides an accurate, quantitative

measurement of modulation quality and overall

system performance.

Dedicated Test Screens

Conveniently accessed, dedicated test screens

allow the user to specify Link Control and Low

Speed Data information contained within Voice

Frames and to specify status symbol value.

Input parameters can be defined as default

values, or uniquely specified by the user.

This feature makes testing easier, more

efficient and robust by allowing operator

specified values to be tested.
