Keysight 5351B Microwave Frequency Counter, 10 Hz - 26.5 GHz

The Keysight 5351B provides fast and precise measurements from 10 Hz to 26.5 GHz and features microwave components that are integrated on a single hybrid gallium arsenide (GaAs) circuit for added speed and reliability. The 5351B distinguished by wide frequency coverage, exceptional sensitivity, fast tracking, high measurement throughput, and wide FM tolerance.

Built-in microprocessors provide math functions, including measurement scaling and offset. Automatic amplitude discrimination measures the frequency of the highest-amplitude signal in a multi-signal environment. A full set of diagnostic routines provides general information and troubleshooting.

The 5351B integrates easily into test systems. English-like commands simplify integration with other components, and the easy-to-read liquid crystal displays can serve as message centers for the system.
