The Keysight E4419A is a dual-channel power meter engineered for accurate average power measurements across RF and microwave frequencies. It delivers simultaneous power readings from two independent sensors, enabling efficient comparative analysis and differential measurements on the benchtop or within automated test equipment systems. The meter accepts Keysight 8480 series and E-series power sensors, providing measurement capability from 100 kHz to 110 GHz with dynamic range up to 90 dB.
