The Keysight N1914A is a dual-channel RF and microwave power meter delivering high-accuracy measurements across 9 kHz to 110 GHz. It combines fast measurement speeds—up to 400 readings/second with E-Series sensors—with absolute accuracy of ±0.02 dB (logarithmic) and ±0.5% (linear). The instrument features an industry-first color LCD display and supports expansion to four channels via USB-connected power sensors. Its -70 dBm to +44 dBm measurement range, multiple connectivity options (GPIB, LAN LXI-C, USB, VGA), and compatibility with E9300, E4410, N8480, and 8480 Series sensors make it suitable for R&D, manufacturing, and field service applications.
