5.运放频率指标的重要性是什么?

Depending on the frequency range to be tested, the amplifier frequency range must also be considered to insure that the excitation signal provided to the shaker is properly conditioned. If not, the amplifier itself may induce significant distortion into the shakers drive signal, compromising the quality of the measurement.

取决于要测试的频率范围,功放的频率范围也必须考虑,以确保提供给激振器的激励信号被恰当的进行了调理。不然,功放自身可能产生极大的失真施加到激振器的驱动信号上,连累测量结果的质量。
