频率:1Hz~1MHz
b.测试误差≤0.1
(2)周期测量
a.测量范围 信号:方波、正弦波
幅度:0.5V~5V[注]
频率:1Hz~1MHz
b.测试误差≤0.1
键盘从上到下,从左到有依次为: 1 2 3 4
5 6 7 8
9 0 . 确认-Design and production of a simple digital frequency meter display. (B) 1. The basic requirements of (1) a. measuring range frequency measurement signal: square wave, sine wave range: 0.5V ~ 5V [Note] frequency: 1Hz ~ 1MHz b. test error of ≤ 0.1 (2) cycle measurement a. measuring range signal: square wave, sine wave range: 0.5V ~ 5V [Note] frequency: 1Hz ~ 1MHz b. Error ≤ 0.1 Test the keyboard from top to bottom, left to have followed: 1 2 3 4 5 67,890. confirm
