The Keysight (formerly Agilent HP) 5352B is a high-performance 40 GHz CW microwave frequency counter designed for fast, precise measurements across a wide range from 10 Hz to 40 GHz (extendable to 46 GHz with Option 005). Featuring microwave components integrated on a single hybrid GaAs circuit, the 5352B offers outstanding sensitivity, fast acquisition times, robust FM tolerance, and rapid tracking of frequency drift. With automated amplitude discrimination, math scaling, and comprehensive GPIB programmability, the 5352B is ideal for demanding microwave test environments, VCO testing, and automated systems integration.
