We have got the instrument ( pressure gauge , thermometer , tachometer , current meter , universal meter ) ready for the experiment ( test ) 我们已经准备好做实验（试验）的确是的仪器（压力表、温度计、转速计、电流表、万用表） 。
Optional midas 2 . 0 modules provide the synchronization of high - speed video with instrumentation data from a wide variety of sensors , gauges , tachometers , irig gps encoders and other devices 高速摄像仪提供视频与数据同步，如各种传感器测试组件转速计irig gps编码器和其它测试等等。
The a / d and cap circuits on dsp sample the voltage and current signals coming from the signal sampling circuit and the speed signal of the motor respectively . the " dead time " register of the dsp prevent directive - through of the igbts on the up and the down bridge arms 利用dsp上的死区寄存器设置ipm驱动信号的死区时间防止上下桥臂igbt的直通；利用板上集成的a / d转换器采集经过板级外围电路处理的电路信号；利用板上的捕获单元cap采集通过转速计的输出从而得到电机的转速。
