Features Emulate the HP/Agilent 8920 Series Analog Tests
The 3920 provides test features found on the HP/Agilent 8920 used extensively in the analog radio production environment. Included is a remote language interpreter that allows users an upgrade path from their obsolete 8920's. This interpreter provides many compatibility commands to reduce the number of changes required to existing applications that control the 8920 over a GPIB interface.

IQCreator™ Compatibility (390OPT054)
The 3920 supports the popular Aeroflex IQCreator software from Aeroflex and has the ability to generate single or multiple carriers with user defined digital or analog modulation types unique to each carrier within a 50 kHz bandwidth (actual bandwidth is dependent on the maximum sample rate). With IQCreator capability, the 3920 now provides a high level of future-proof capability by providing engineers and production test users the ability to update their 3920 generator capabilities with digital modulation formats, whether they are proprietary or part of a new standard.

Harmonics and Spurious Option (390XOPT060)
With the 3920, measuring the harmonics and spurious of a transmitted signal is as easy as pushing a button. This option automatically and quickly finds the second and third harmonics and the spurious signals. It operates by first finding the frequency of the fundamental and then taking measurements at the location of the second and third harmonics. Then it does a search for spurious by searching through the entire band, looking for any signal that is greater than a level set by the user. All of this information is then presented to a user in an easy to read and interpret format.

Tracking Generator Option (390XOPT061)
The 3920 includes a tracking generator as part of the spectrum analyzer. The tracking generator enables the 3920 to sweep cables, antennas, duplexers, and other RF components of an analog or digital system.

APCO P25/Project 25 (390XOPT200)
This optional feature provides the 3920 with the ability to transmit and receive P25 modulated signals and perform RF and modulation measurements on P25 radios and systems. P25 Measurements include: Modulation Fidelity, Symbol Deviation, Symbol Clock Error, TX Bit Error, RX Bit Error, Frequency Error, and Transmit Power. This system supports all modulation formats that are available in P25 systems.  Available modulation formats for P25 Phase 1 include: C4FM, CQPSK, LSM (Linear Simulcast Modulation).  Phase 2 modulation formats: HDQPSK and HCPM are now available as well.  Powerful diagnostic displays provide immediate indications of transmitter performance.  Graphical displays include: Symbol Distribution Plot, Eye Diagram, Constellation and Trajectory Plots. These powerful tools provide immediate indications of a transmitter’s performance characteristics.  Poor performance from the transmitter can cause a severe reduction in coverage area for digital systems.

APCO 25/P25 Trunking Option (390XOPT201)
Aeroflex has an exclusive new option for the Aeroflex 3920 Series Digital Radio Test Set to support P25 Trunking. Designed to support the needs of basic P25 testing as well as complex analysis of advanced P25 systems, the 3920 Series features powerful analysis tools with an easy to use graphics interface. The new P25 Trunking Option (Option 201) supports trunking operation in the VHF/UHF/700 MHz and 800 MHz bands. Exclusive features include the ability to simultaneously generate a control channel and traffic channel with duplex offset capability to go from 1 MHz to 2.7 GHz. With the 3920 Series, operators with radios on P25 systems can rest assure their radios are in proper working order, providing the critical interoperability needed for today's communications.

The Auto-Test II system provides the tools for the development of applications that can include softkeys, user input and test results. The control of the functions of the box is through the same commands that are used for RCI. This gives the user the power to create their own way of using the 3920, and it is done with a language that is familiar to many programmers. Auto-Test II is available separately for each supported system.

APX™ Series Alignment Application (390XOPT604)

The APX Series radios are dual band and can be configured with any two band combinations. The application will test and align installed bands. Mobile power alignment is included in this option and requires the use of the standard internal DMM and optional AC24011 (10 AMP Current Shunt). The radio's standard USB programming cable is used directly by the 3920 to control the radio in test mode. Both Analog and Digital tests are performed to ensure the radio is performing at optimum performance. Alignments are available for Power, Referemce Oscillator, Deviation Balance and Receiver Front End. P25 Performance tests are available for Modulation Fidelity, Symbol Deviation and RX BER.
