The Keysight (Agilent) 5340A Automatic Microwave Counter offers frequency measurements from 10Hz to 18GHz, with high sensitivity across three ranges: -30 dBm (10Hz–500MHz), -35 dBm (500MHz–10GHz), and -25 dBm (10–18GHz). It features a 50-ohm input impedance and a precision 10MHz crystal timebase with an aging rate of less than 3x10⁻⁷ per month. With selectable resolution steps of 1Hz to 1MHz and a basic accuracy defined as ±(1 count + timebase error), it is built for precision in demanding applications.
This versatile instrument is ideal for high-frequency RF and microwave testing, offering consistent accuracy and reliability. Its proven performance has made it a preferred choice among telecommunications, aerospace, and research professionals.
