The related technical problems, the dynamic measuring stability of the instrument and the setting of the sampling window directly effecting the signal trueness are discussed.
讨论了有关的测试技术问题，特别对仪器动态测试稳定性问题进行了讨论，还对直接影响信号真实度的采样窗口设定问题进行了讨论。
Measuring apparatus can use general digital voltmeter with appropriate accuracy, but generating standard dynamic strain signal is a problem which hasn't been well solved.
测量仪器可用适当精度的通用数字电压表，而标准动态应变的产生则是尚未很好解决的问题。
Measuring the dynamic strain involves the constant modification of gain, as determined by the signal amplitude. This practice suffers from the complex test and the low accuracy.
在动态应变信号测试中，经常需要根据信号的幅值不断调整放大器的放大倍数，测量电路复杂，精度低。
