The Keysight (formerly Agilent) N1914A is a versatile, dual-channel EPM Series RF and microwave power meter designed to deliver reliable average power measurements. With the capability to measure power from -70 dBm to +44 dBm and frequencies from 9 kHz to 110 GHz (depending on the connected sensor), it offers significant performance enhancements over legacy models while maintaining strict code compatibility with the widely used E4418B, E4419B, and 438A power meters. When equipped with optional USB host ports, the N1914A's dual-channel architecture can be expanded with two additional U2000 Series USB power sensors, transforming it into a complete 4-channel power measurement solution. It features a modern, high-resolution color display and comprehensive LAN LXI-C, USB, and GPIB connectivity.
