Additional Features: Fast measurement speed (up to 100 readings per second, over the GPIB, with E-series sensors) Speed improvement of x2 using the 8480 series power sensor (compared to 437B) No range-switching delays with 8480 series sensors, and only one fast-range switching point with E-series sensors High-resolution display with backlighting for a wide viewing angle of displayed data Save and recall of up to 10 instrument states GPIB connector for remote control of all functions Code compatibility with 438A Conformity to CE and CSA standards The Agilent E4419A is fully compatible with the 8480 series of power sensors and the E-series of power sensors (except the E9320A Family). Depending upon which sensor is used, the Agilent E4419A can measure from -70 dBm to +44 dBm at frequencies from 100 kHz to 110 GHz. Designed for bench and automatic test equipment use (ATE), the E4419A makes fast (up to 100 readings per second with E-series sensors), accurate and repeatable power measurements. The Agilent E4419A is a true dual-channel power meter, which means that you get two simultaneous power readings on the display.
