Aeroflex Announces the New 3920 Radio Test Set

New features include high performance DMM functions and extended audio test feature
and expanded USB interface capabilities.
Aeroflex has announced the introduction of the new 3920 Digital Radio Test Set. The next
generation of the 3900 Series, the 3920 replaces the 3901 and 3902 Radio Test Sets. While
providing new features and functions, the 3920 continues to perform all the tests previously
capable with the 3901 and the 3902, including TETRA Mobile Station, Base Station and Direct
Mode test features.

The 3920 features new enhancements that provides test professionals with more test
capabilities integrated into one system, and offers extended analysis range and file
management functions.

An optional 3 ½ digit DMM function includes the ability to measure AC and DC voltage, current
as well as resistance. AC voltages up to 150 Volts rms and DC voltages to 150 Volts can now
be quickly measured using the easily accessible front panel connections or via GPIB and
Ethernet commands. Additionally, the 3920 provides measurement of current up to 20 amps
(with optional external shunt) and has a fully automated ohmmeter capable of measuring from
0 to 20 MΩ. The 3920 is fully protected against over voltage or current conditions with an easy
to access front panel fuse.

The 3920 also provides new capabilities to export files to USB drives and connect external
USB input devices for even easier operation of the 3920. Located just below the optional
DMM ports, the USB interface provides easy front panel access as a standard feature.

Additionally, the 3920 offers extended audio input ranges for measuring and analyzing audio
signals with extended range inputs of up to 30 Volts rms. With this added capability, the 3920
can be used for analyzing high level audio signals including measurements for AF Frequency,
AF Level, SINAD, Distortion, Hum and Noise and Signal to Noise Ratio.

Designed to be a software-defined radio test system, the 3920 supports AM and FM analysis
as a standard feature, but optionally provides extended test capabilities for new digital radio
communication systems including TETRA, Project 25 and Motorola’s new HPD® technologies.
In addition, the 3920 emulates the now discontinued Agilent 8920A/B series in test capabilities
and GPIB commands, with over 90% of the 8920B commands emulated by the 3920.

Existing users of the 3901 and the 3902 Radio Test Sets will still be able to take advantage of
software upgrades, as software releases for the 3920 will also continue to support existing
3901 and 3902 systems, with the exception of the DMM functions and extended audio ranges
provides with the 3920.

The 3920, without the DMM option, is priced equivalent to the 3901. The DMM option can be
ordered as option OPT53. Additionally, the DMM Lead Kit can be ordered under AC24009 and
the 20 amp current shunt ordered under AC24010.
