Courtesy: AeroflexAeroflex Incorporated's (NYSE:ARX), 3920B Digital Radio Test Set is designed for Analog AM and FM, Digital P25, P25 Phase II, DMR, NXDN, dPMR, TETRA and TEDS technologies. The 3920B features a 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's low phase noise RF signal generator provides 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.
