Aeroflex Introduces the 3920B Digital Radio Test Set
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
Aeroflex Incorporated, a wholly owned subsidiary of Aeroflex Holding
Corp. (NYSE:ARX), 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.
“Today’s narrowband digital radios employ very
sensitive and high performance receivers. These new digital radios
routinely provide receiver sensitivity levels better than -119 dBm. In
order to test these receivers accurately, it is important to understand
that these receivers can be adversely impacted by the incidental phase
noise of the generator used to test sensitivity or selectivity. Digital
technologies such as P25 Phase II employ phase modulation techniques
(H-CPM) where any added phase noise from the generator can cause
erroneous measurements, especially when determining the digital
sensitivity of the receiver using Bit Error Rate (BER) calculations,”
said Rob Barden, Director of Product Marketing for Radio Test Systems at
Aeroflex. “The 3920B provides the test engineer and technician with the
confidence that the test system is not inducing errors in their
measurements with excessive phase noise.”
The 3920B includes all
the features and function 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 near future.
