Agilent/Keysight E4419B

The Agilent/Keysight E4419B is a dual-channel, programmable power meter for RF and microwave power measurements in benchtop and automated test equipment environments. It delivers fast, accurate power readings across a wide frequency range, with measurement speeds up to 100 readings per second over GPIB using E-series sensors in FAST mode. The instrument supports both absolute and relative measurements in multiple display units and resolutions, making it suitable for production testing, field service, and laboratory characterization of RF and microwave components and systems.
