Agilent/Keysight E4418B

The Agilent/Keysight E4418B is a single-channel, programmable average power meter engineered for benchtop and automatic test equipment (ATE) applications. It delivers accurate power measurements across 9 kHz to 110 GHz (sensor dependent) with measurement speeds up to 200 readings per second over GPIB. The instrument features a high-resolution LCD display with LED backlighting and contrast control, dual-mode hardkey and softkey interfaces, and the ability to store and recall ten instrument configurations for streamlined repetitive measurements. Optional internal rechargeable battery operation extends portability to 5.5 hours of continuous use. Code compatibility with legacy Agilent/HP 436A and 437B meters protects existing automated test procedures and software investments.

– Technical Specifications
