本文件规定了用于阵列探头的多通道超声相控阵仪器的功能特性，并提供了测量和验证方法。 本文件也适用于自动化系统中的超声相控阵仪器；但还需要进行其他测试，以确保性能令人满意。当相控阵仪器是自动化系统的一部分时，可通过相关方之间的协议修改验收标准。 本文件也可部分适用于FMC工具和TFM工具。 本文件给出了验证的范围，并定义了0.5？频率范围内的验收标准MHz至10兆赫。

This document specifies the functional characteristics of multi-channel ultrasonic phased array instruments used for array probes and provides methods for their measurement and verification. This document is also applicable to ultrasonic phased array instruments in automated systems; but other tests can be needed to ensure satisfactory performance. When the phased array instrument is a part of an automated system, the acceptance criteria can be modified by agreement between the parties involved. This document also can partly be applicable to FMC instruments and TFM instruments. This document gives the extent of the verification and defines acceptance criteria within a frequency range of 0,5？MHz to 10？MHz.
