The Keysight N1914A is a dual-channel average power meter designed for precise RF power measurement in R&D, manufacturing, and field service environments. It delivers repeatable results across a broad frequency spectrum with an industry-first color LCD display for real-time data visualization. The instrument expands to four measurement channels via optional USB connectivity to U2000 Series sensors and supports automated frequency and power sweep measurements with external trigger capability. Code-compatible with legacy Keysight power meters, the N1914A integrates into existing test systems.
