The Keysight (Agilent) 5342A Frequency Counter delivers automatic frequency measurement from 10Hz to 18GHz, with selectable 50Ω and 1MΩ input attenuation. It supports dual input ranges and withstands FM carriers up to 50MHz peak-to-peak, making it ideal for communications testing. With 1Hz resolution on an 11-digit sectional display, and microprocessor-driven math functions like IF offset, it’s a versatile and precise tool. Available options include high-stability timebase, amplitude measurements, dynamic range extension, D/A conversion, frequency extension to 24GHz, GPIB, and more.
It is especially suited for RF, telecom, and satellite applications where frequency stability, signal modulation tolerance, and compact design are critical. The intuitive interface and optional modules enhance adaptability across test scenarios.
