sweeping frequency measurement的意思|示意

The digital tester for frequency response characteristic, which is also called frequency-sweeping instrument, plays a very important role in modern electronic measurement.

扫频仪也称频率特性测试仪，用于测试网络的幅频特性和相频特性，在现代电子测量中占有重要的位置。

When frequency sweeping method being used properly for measuring amplitude-frequency characteristics, the analysis and estimation of errors in measurement results could be avoided.

正确使用扫频法测量幅频特性，可以避免大量测量结果中误差的分析与估算。
