Aeroflex Introduces the 3920B Digital Radio Test Set
ANAHEIM—APCO International 2013—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 -119dBm. In order to test these receivers accurately, it is important to understandthat 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’sexpanding 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.

The 3920B Digital Radio Test Set is now available with a delivery time of 6-8 weeks. For more information about pricing, contact your local Aeroflex sales office by visiting or calling Aeroflex Sales at (800) 835-2352 or firstname.lastname@example.org.
