The Agilent/Keysight EPM-441A is a single-channel programmable power meter engineered for precise average power measurements across demanding RF and microwave applications. This benchtop and ATE-integrated instrument delivers absolute accuracy of ±0.02 dB (logarithmic) and ±0.5% (linear), with dynamic ranges up to 90 dB depending on sensor selection. Fast measurement capability—up to 200 readings per second over GPIB with ECP/E-series sensors—enables efficient production testing and characterization workflows.
