Agilent / HP / Keysight 5386A

This counter offers prescaled measurements to 3GHz based on gallium arsenide (GaAs) technology.

The GaAs prescaler and attenuator circuitry are integrated on a hybrid substrate.

Bipolar technology permits the integration of reciprocal counting and interpolation techniques on a single integrated circuit.

The tightly integrated design achieves overall high performance, excellent reliability, and low cost of ownership.

It incorporates a 12 character display, accessible remotely via HP-IB.

The liquid crystal display (LCD) can be read in direct sunlight, and has large characters that can be seen from the end of a bench or mounted high in a test rack.

It can be easily carried to remote locations for service and calibration applications.
