本文提出了减小和消除用扫频法测幅频特性动态误差的具体措施,并设计了一具简易电子开关,将它与 TB-3扫频仪一起使用,以“同源”双迹显示来调测幅频特性,则动态误差便可消除。
In this paper, the specific measures to reduce and eliminate the dynamic error of amplitude and frequency characteristics measured by swept-frequency method are proposed. A simple electronic switch is designed and used together with the TB-3 scanner to display “homology” To adjust the amplitude-frequency characteristics, the dynamic error can be eliminated.
