英文摘要: |
Signal conditioner is a significant part of dynamic measurement system, the bandwidth, amplification and filtering are main indexes to evaluate the performance. The output signal amplitude and phase of the dynamic measurement system mainly characterized the test results. The influence research about dynamic performance of signal conditioner to dynamic measurement system output signal amplitude and phase are studied in this paper, conducted the experiment then analyzed the attenuation of output signal amplitude and phase caused by the bandwidth, amplification and filtering. Improving the accuracy of dynamic measurement results, optimizing the dynamic performance of measurement system is the significance of this paper. |
