E4418B EPM系列单通道功率计

EPM系列单通道功率计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”.
