Bit Error Rate (BER) Testing

BER testing can be performed on base stations

and repeaters which support BER test capabil-

ity. The R2670 and R2625 in Project 25 trunking

mode can monitor RF transmissions modulated

with a V.52 BER test pattern.

This testing provides an accurate, quantitative

measurement of modulation quality and system

performance.

Full Duplex Test of Base

Station Repeaters

Project 25 compatible FDMA digital C4FM

modulation of 1011 Hz test pattern with simul-

taneous C4FM/LSM demodulation of voice.

Performs average power level measurements

under actual operating conditions, with a

selectable averaging interval.

This feature allows the operator to monitor

transmitter power levels under traffic condi-

tions for both C4FM and LSM modulated

signals while verifying receipt and transmit of

the C4FM modulated 1011 Hz test pattern.

Dynamic Call Testing

of Subscriber Radios

Project 25 compatible FDMA Digital C4FM

modulation and demodulation on trunked

channels allows testing of radio registration

process and ability to receive call alert

indication. These features also permit testing

of trunked radio capabilities such as a

transition to a traffic channel from a control

channel, quality of radio-transmitted signal,

as well as voice quality.

The operator can verify both radio system

compatibility and functionality without having

to rely on an actual system for confirmation.

In addition, precise radio performance and

programming data ensure operation within

appropriate system performance specifica-

tions.

Closed Cover Measurements

Measurements can be made while a simulated

‘live’ call is maintained with the radio under

test.

Project 25 Trunking Test Option

Feature Description Benefits

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

This affords the user greater diagnostic

capability to ensure proper radio operation

with just a single RF connection to the radio.
