The Keysight N1913B EPM Series Single-Channel Power Meter delivers accurate average power measurements across DC to 120 GHz with dynamic range from -70 dBm to +44 dBm. Built for bench, rack, and field deployment, this instrument combines a color LCD display with measurement speeds up to 400 readings/second and absolute accuracy of ±0.02 dB (logarithmic) or ±0.5% (linear). The meter expands to three channels via optional USB power sensors and integrates into automated test systems with external trigger capability.
