Aeroflex in Wichita, Kan., is offering the integrated 3920 digital radio test set with extended range and file management for analog, TETRA, and P25 technologies. An optional 3.5-digit DMM function includes the ability to measure AC and DC voltage, current, as well as resistance. AC voltages as strong as 150 volts rms and DC voltages to 150 volts can be measured from the front-panel connections or via GPIB and Ethernet commands. The 3920 is protected against over voltage or current conditions with a front-panel fuse. The 3920 also provides capabilities to export files to USB drives and connect external USB input devices. Located below the optional DMM ports, the USB interface provides front-panel access as a standard feature. Additionally, the 3920 offers audio input ranges for measuring and analyzing audio signals with range inputs of as much as 30 volts rms for analyzing high-level audio signals, including measurements for AF Frequency, AF Level, SINAD, Distortion, Hum and Noise, and Signal-to-Noise Ratio. The 3920 provides RF operation from 10 MHz (usable from 100 kHz) to 1 GHz standard, with OPT058 providing the ability to go to 2.7 GHz. Designed as a software-defined radio test system, the 3920 supports AM and FM analysis as a standard feature, but optionally provides extended test capabilities for new digital radio communication systems including TETRA, Project 25, and Motorola’s HPD technologies. The 3920 also emulates the now discontinued Agilent 8920A/B series in test capabilities and GPIB commands, with more than 90 percent of the 8920B commands emulated by the 3920. The 3920 is CE and UL compliant. For more information, contact Aeroflex online at www.aeroflex.com.
