本标准描述了适用于大信号应用的变容二极管特性的参数和测量方法。这将通过参考IEEE Std 318-1971《固态器件试验使用指南:变容二极管测量，第一部分——小信号测量》（如适用）中规定的参数和方法来实现，并在必要时对其进行修改和补充，以用于大信号器件。

This standard describes parameters and methods of measurement suitable for the characterization of varactors intended for large-signal application. This will be done by reference to the parameters and methods prescribed in IEEE Std 318-1971, Trial-Use Guide on Solid-State Devices: Varactor Measurements, Part I -- Small Signal Measurements, where they are applicable, and by modification and supplementation of them where necessary for use with large-signal devices.
