Abstract: Insertion loss and return loss are the main calibration parameters for network cable analyzers. At present, JJF 1494-2014 Calibration Specification for Network Cable Analyzers provides the corresponding calibration method for category six cables (signal frequency up to 250 MHz). In this paper, based on high-performance RF devices, a power loss calibration standard for network cable analyzer is developed, which is suitable for calibrating parameters of category eight cables (frequency up to 2000 MHz). The vector network analyzer calibrates the above-mentioned standards, and calibration of the high-frequency network cable analyzer is realized.
