Feature Description Benefits

Project 25, ASTRO and SECURENET Common Features

Encryption Test Option

Voice and embedded data encode and decode

testing can also be done in the encrypted

mode using either test keys, which are

permanently stored in the R2670, or actual

customer-selected keys which can be loaded

into the unit using a compatible key loader.

This feature allows verification of the proper

operation and system compatibility using

actual encryption algorithms.

Baseband Audio Scope Display

This display provides a clear graphic image of

the audio baseband, signal-selectable at either

the vocoder input in generate mode or the

vocoder output in monitor mode.

This feature provides greater assurance of

proper system operation through its graphic

display of voice or tone modulation.

ASTRO Test Option

Feature Description Benefits

Dedicated Test Screens

Conveniently accessed, dedicated test screens

can be set up as a start-up default condition

or as a programmable test set-up. Dedicated

ASTRO test screens are windowed with RF and

Modulation control screens to simultaneously

display test results along with their test

conditions. While in ASTRO mode, standard

diagnostic test screens can be easily

accessed.

This feature makes testing easier and

more efficient. It also provides quantitative RF

measurements to ensure proper system

performance margin.

Voice Mode System Testing

This feature provides ASTRO compatible FDMA

Digital C4FM modulation and demodulation

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 in

ASTRO mode can generate or monitor

RF transmissions modulated with a V.52 BER

test pattern.

This testing provides an accurate quantitative

measurement of modulation quality and overall

system performance. The Duplex mode

supports loop-back testing.

(Optional in R2670; not available in R2600 and R2625)
