							SECURENET Test Option
Voice Mode System TestingVoice mode system testing provides
SECURENETcompatible modulation anddemodulation with vocoding. Generate andmonitor modes support functional voice testingin the encrypted mode using either test keys
stored in the R2670, or customerselected keys
provided by a separate DX key loader. TheR2670 also emulates an AX, BX, or CX key
loader, which can be used to download testkeys to a compatible radio.This feature allows verification of the proper
operation and system compatibility using actual encryption algorithms.
Bit Error Rate (BER) Testing
Dedicated Test ScreensBER can be measured using the builtin 
V.52 test pattern generator. This standard, nonencrypted pattern can be used to either modulate the Generator or inject into a radio or system under test via the baseband output.This BER pattern can then be recovered from
the radio system either through the analyzer’sreceiver or from its baseband input to performa closed loop BER test. The BER test is also
available in the unit’s Duplex mode.
Conveniently accessed, dedicated test screens
can be set up as a startup default condition ora programmable test setup. DedicatedSECURENET test screens are windowed with RF and Modulation control screens tosimultaneously display test results along withtheir test conditions. While in SECURENETmode, standard diagnostic test screens can be readily accessed.
This testing provides an accurate, quantitative
measurement of modulation quality and overallsystem performance. Loopback testing is supported while operating in Duplex mode.
This feature makes testing easier and 
more efficient. It also provides quantitative RF measurements to ensure proper system performance margin.
