August 22, 2012 // By Jean-Pierre Joosting
Aeroflex has launched the 3550 digital radio test system featuring an industry-first colour touch-screen and enhanced specifications to provide users with a lightweight, easy to use, and reliable digital radio test system.

Designed for Professional Mobile Radio (PMR), public safety, and other land mobile radio applications, the test system quickly isolates problems and assesses performance in AM/FM radios, with options for P25, DMR, NXDN™, and dPMR radio systems.

The 3550 test system is lightweight (3.8 kg including battery) for field-testing of analogue, DMR, P25, NXDN, and dPMR systems, and features 4.5 hours of continuous operation with its internal battery. Further, the 3550 test system allows the user to test all aspects of the radio system — the transmitter, receiver, cables, and antennas — with powerful features typically found only in bench top equipment. It also meets MIL-PRF-28800A specifications for humidity, shock, and vibration, with an operating range of 0º C to +50º C.

Typical specifications include phase noise of -95 dBc/Hz, RF signal generator level accuracy of ±1.5 dB, FM deviation meter accuracy of 4%, and -140 dBm spectrum analyzer.
