The Keysight E4418B EPM Series Power Meter is a single-channel average power meter engineered for benchtop and Automatic Test Equipment (ATE) environments. It delivers high-speed, high-accuracy measurements and operates with Keysight 8480 series and E-series power sensors. The instrument supports multiple display formats—dBm, Watts, and dB relative to reference—and includes trend plotting and statistical analysis capabilities.
– Technical Specifications
Measurement Performance
• Measurement type: Average power, single channel
