Aeroflex announced today the introduction of the new 3920B Digital Radio Test Set for Analog
AM and FM, Digital P25, P25 Phase II, DMR, NXDN™, dPMR, TETRA and TEDS
technologies. The 3920B features a new low phase noise RF signal generator in addition to the
already advanced functionality available on the Aeroflex 3900 Series Radio Test Sets. The
3920B is the direct replacement for all versions of the Aeroflex 3900 Series, including the
3901, the 3902 and the 3920.
The 3920B features a new low phase noise RF signal generator providing enhanced spectral
purity with SSB phase noise specified at -110 dBc/Hz at 10 kHz offset. This level of
performance is achieved at an offset from the carrier that is significantly less than the industry
standard for this type of specification, which is typically 20 kHz. The ability of the 3920B to
achieve such low phase noise specifications close to the carrier, makes the 3920B an ideal
test solution for today’s digital narrowband or analog receiver testing where narrowband phase
noise is critical.
The 3920B includes all the features and functions of the 3920. This includes Aeroflex’s
expanding library of Auto-Test II capabilities for automated test and alignment of a wide range
of mission critical radios. The 3920B provides Auto-Test II capabilities for Motorola APX™,
Motorola XTS® and XTL™ Series, as well as Harris, EF Johnson, Relm/BK and Kenwood
radios with support for additional radios coming in the new future.
