CODA是第一款也是唯一一款能够使用Innerspec的专利脉冲发生器技术同时使用电磁超声探伤和压电传感器的紧凑型大功率超声探伤仪。
在 EMAT 模式下，该仪器可以以 800Vpp/8kW 的峰值功率在 1MHz 到 8MHz 的脉冲重复率下脉冲 1 到 3 个完整周期。在压电模式下，该仪器以 2kHz 的脉冲重复频率将半周期方波从 100V 脉冲到 400V。该仪器可以在电磁超声和压电模式下以脉冲回波或一发一发收模式工作。
CODA 仪器使用 Innerspec 技术操作平台 (ITOP) 使用 NDT-WEB 应用程序软件。该仪器播放 WiFi 信号，允许使用可拆卸手机/平板电脑（随附在内）或使用标准 Web 界面从任何连接的无线设备远程控制仪器。
CODA 仪器有三种不同的配置可供选择：
CODA- 基本模型无需编码器即可提供所有 EMAT 和压电功能。
CODA+- 它包括一个单轴编码器输入，用于使用手动或自动扫描仪进行编码的条形图和C扫描。
CODA SM- （应力测量）。它专为应力测量而设计，允许使用Innerspec的专有技术按顺序对两通道电磁超声波传感器进行脉冲处理。根据应用，它随附定制的压力软件和不同的定位夹具。
