Agilent E4419B High-Performance Power Meter

The Agilent E4419B is a high-performance dual-channel programmable power meter. It is fully compatible with the 8480 series power sensors and the new E-series power sensors. Depending on the sensor used, the E4419B can measure power from -70dBm to +44dBm within a frequency range of 100KHz to 110GHz.
When used in benchtop test equipment and automated test equipment (ATE), the E4419B performs fast (up to 100 readings per second with E-series sensors), accurate, and repeatable power measurements. The E4419B is a true dual-channel power meter, meaning it can display two simultaneous power readings on the screen.

The E4419B power meter features a high-resolution LCD display with LED backlight and contrast control, allowing users to view power readings from a distance with a wide viewing angle under various lighting conditions. Users can display both digital and analog readings on the instrument's split screen. The analog peak bar graph meter enables precise adjustments.
The user interface is easy to understand and operate, thanks to hardware for the most commonly used functions and dedicated function key menus that simplify instrument configuration for different applications. The instrument provides difference (A-B, B-A) and ratio (A/B, B/A) functions, and can store and recall up to 10 instrument configurations, reducing the need for repetitive setup sequences.
With its code compatibility with the 438A and identical dimensions (height: 88.5mm, width: 212.6mm), the E4419B power meter is easily integrated into rack-mounted automated test equipment systems.
