The Keysight 53147A is a multifunction microwave instrument combining frequency counter, power meter, and DC voltmeter in a single compact chassis. It delivers precise frequency measurements to 20 GHz, calibrated power assessment across a wide dynamic range, and DC voltage monitoring—three critical capabilities for ATE integration, telecommunications, aerospace, and defense test environments where space efficiency and measurement versatility are essential.

– Compatibility & Integration
The 53147A accepts Agilent 8480 series power sensors, including 8481 (10 MHz–18 GHz, N connector), 8485 (50 MHz–26.5 GHz, APC-3.5 mm), and 8487 (50 MHz–50 GHz, 2.4 mm) models. High-sensitivity variants extend measurement capability to −70 dBm. Integration with ATE systems benefits from compact form factor and three independently configurable measurement functions.
