POCSAG Encode
• Send Alphanumeric or Numeric POCSAG formatted pages
• Select any rate from 400 to 4800 Hz
• Select deviation from 0 to 50,000 Hz
• Select Normal or Inverted for polarity
• Pick from a selection of canned messages or create a custom
message
• Select RIC (Radio Identification Code) of encoded message, or
send to a range of RIC’s
POCSAG Decode
• Select Decode Format - either Automatic, Alphanumeric or
Numeric
• Select Decode Filter - decode all messages or only messages to a
user selectable RIC
• Select Normal or Inverted Polarity for decoding
• Displays deviation and rate of decoded message
• Displays the RIC and the type bits (two bits) of the decoded
messages as well as the message
Chinese GUi (390XOPT090)
This option enables the selection of either Chinese or English as
the language for the graphical user interface for the Analog Duplex
system. When enabled, a selection is added to the utilities screen
that allows the user to choose between English or Chinese character
display in the audio Analog Duplex system.

OPTiOnAl SYSTEM PERSOnAliTiES
In addition to the Analog Duplex system, the 3920B can sup-
port a number of optional test systems or personalities, installed
concurrently. Personalities include:
• TETRA digital trunked radio systems for mobile station and base
station testing
• TETRA direct mode testing
• APCO P25 conventional and trunked radios
• APCO P25 Phase II TDMA
• SmartZone and SMARTNET
• DMR (Digital Mobile Radio)
• NXDN
• HPD (High Performance Data)
• dPMR (digital Private Mobile Radio)
• ARIB T98 (Digital Convenience Radio Equipment For Simplified
Service)
P25 COnVEnTiOnAl OPERATiOn (390XOPT200)
The 3920B P25 Conventional Option provides test features for test-
ing P25 radios and systems. Featured is the ability to transmit P25
C4FM standard waveforms and analyze P25 received waveforms. The
analysis of the received waveforms consists of the ability to perform
RF and modulation parametric tests. The vocoder enables the user
to perform transmit and receive audio testing. Included in this option
is the capability to:
• Measure C4FM modulation fidelity and symbol deviation
• Measure power, frequency error and TX BER
• Measure symbol clock error
• Measure RX BER
• Display eye diagram of C4FM demodulation
• Display constellation plot of C4FM symbols
• Display C4FM symbol deviation distribution plot
• Transmit full TIA/EIA-102 test patterns (STD1011, CAL,
SILENCE, STD511, etc.) as specified by TIA- EIA-102.CAAA-C
• Transmit and receive live audio using the vocoder
• Transmit stored speech patterns
• Decode voice channel header and link control messages
• Encode link control messages
• Perform DES encryption
