The 3920's optional three-and-a-half digital multimeter measures AC and DC voltage, current and resistance. Use the front panel port to quickly measure AC voltages up to 150Vrms and DC voltages up to 150V. In addition, the 3920 can measure currents up to 20A (using an optional external shunt) and can be used as a fully automated ohmmeter capable of measuring 0-20 ohm resistance. With an easy-to-install front-panel fuse, the 3920 is fully protected against overvoltage or overcurrent conditions. The 3920 also supports the ability to export files to a USB memory, as well as an external USB input device such as a mouse and keyboard to simplify the operation of the 3920. The USB interface located directly below the front panel DMM port is more user friendly. The GPIB port and network port of the instrument are convenient for remote operation of the instrument, and the automatic test program can greatly improve the efficiency of use.
In addition, the 3920 can measure and analyze audio signals up to 30Vrms. The 3920 can be used to fully analyze audio signals, including measuring AF frequency, AF level, SINAD, distortion, AC noise, and signal-to-noise ratio. The 3920 has a standard RF range from 10MHz (available from 100kHz) to 1GHz, with the OPT058 installed to extend the operating band to 2.7GHz.
As a software-defined radio tester, the 3920 supports AM and FM analysis as a standard feature, but for new digital radio communication systems such as TETRA, Project25 and Motorola HPD technology, the tester provides extended test functionality via options. The 3920 also simulates the now-discontinued Agilent 8920A/B Series in terms of test functions and GPIB instruction codes, and can simulate more than 90% of the 8920B commands. The 3920 is fully compliant with CE and UL standards.
Aeroflex Releases 920 Digital RF Integrated Tester
Aeroflex announces the introduction of the new 3920 digital RF integrated tester for analog systems, TETRA and P25 technology. With new enhancements, the 3920 provides professional testers with more integrated test functions, convenient remote control and powerful file management. The new generation of the Aeroflex 3900 series 3920 will replace the original 3901 and 3902 RF testers. With more new features and new features, the 3920 can still support all of the test functions previously performed by the 3901 and 3902, including TETRA mobile, base station and pass-through mode testing.
