Wireless 3920B Series Analog and Digital Radio Test Platform Featuring Improved RF Signal Generator Phase Noise Performance Introducing the 3920B, the latest radio test solution from Aeroflex for engineering, production and field service applications. The 3920B features an improvement to the RF signal generator phase noise specification of -110 dBc/Hz at 10 kHz offset. The instrument provides a comprehensive range of general purpose analog measurement facilities as well as advanced digital test options.

The one test set for all your narrowbanding test needs! High Performance With the largest selection of digital radio options of any radio test set, the 3920B will meet all of your narrowbanding test needs, both now and in the future. The software defined digital architecture of the 3920B provides for future technology enhancements as new digital technology becomes available.

Audio Analyzer (390XOPT055) With 390XOPT055, the 3920B provides audio spectral analysis of the recovered audio signal, either from the audio inputs or from the demodulated RF signal. This feature allows users to view frequency amplitude in relation to other audio frequencies and to isolate problems such as noise in audio circuits. With a frequency range of 1 Hz to 24 kHz, the audio analyzer covers more than the full audio frequency range of mobiles and hand-helds.

P25 Trunking Operation VHF/UHF/700/800 MHz (390XOPT201) To further enhance P25 operation, the addition of the P25 trunking option allows simulation of a P25 control channel in any frequency band. Channel plans may be configured to test virtually any P25 trunked system. A simulator tile logs the messages sent by the radio under test and allows the 3920B to simulate a virtual mobile, configured to talk to the radio under test.

P25 Phase II Two-Slot TDMA (Time Division Multiple Access) Physical Layer (390XOPT220) One of the newest features of the 3920B is the capability to test P25 Phase II TDMA operation of both base stations and mobile stations. With this option, the 3920B can measure and analyze the different modulations used for both the outbound and inbound signals used in P25 Phase II.

both mobiles and base stations in the 700 and 800 MHz bands. HPD systems operate within the normal 25 kHz mobile radio bandwidth. The 3920B HPD options provide users with the ability to test High Performance Data systems. HPD can be configured for two modes of operation. When configured to operate in BR Mode the test set simulates base radio operation and is used to test the functionality of Motorola HPD Mobile Subscriber Units (MSU).

• Frequency error • FSK error • Symbol deviation • TX BER • Symbol clock error • Option for testing Direct Mode Operation (DMO) The system supports both 4800 and 9600 baud systems. The 3920B can also analyze the modulation as an eye diagram, symbol distribution plot and a symbol constellation plot. A power over time graph can be used to diagnose power-related issues.
PAGE 10
TETRA Test (TT) Protocol Support The TETRA MS option provides support for the TETRA Test (TT) protocol as defined in ETSI EN 300 394-1. The TT protocol allows the mobile to be tested in a loopback mode whereby the mobiles BER, MER and RBER can all be reported. Audio Testing Subjective audio testing is supported for simplex and duplex calls.
