EPM系列單通道功率計E4418B/9B EPM Series power meter performance characteristics Specifications describe the instrument’s warranted performance and apply after a 30-minute warm-up. These specifications are valid over its operating/environmental range unless otherwise stated and after performing a zero and calibration procedure. Supplemental characteristics (shown in italics) are intended to provide additional information, useful in applying the instrument by giving typical (expected), but not warranted performance parameters. These characteristics are shown in italics or labeled as “typical”, “nominal” or “approximate”. For information on measurement uncertainty calculations, refer to Application Note 64-1C, “Fundamentals of RF and Microwave Power Measurements”, literature number 5965-6380E. Compatible power sensors: E4410 and E9300 E-Series, 8480 Series and N8480 Series average power sensors 1.
