示波器中符号的意思是什么?
Vtop=5.05V,——波形顶端电压值
Vbase=56.9mV,——波形底端电压值
Vamp=5.01V,——波形幅度值
Vrms=1.98V,——电压均方根值
Prd=669.0us,——周期
Rise<4.00us,——上升时间
Fall<4.00us,——下降时间
+wid=125.0us,——正脉宽
-wid=544.0us,——负脉宽
+Duty=18.7%,——正占空比,一个方波正脉宽长度占整个周期的百分比
-Duty=81.2%,——负占空比,一个方波负脉宽长度占整个周期的百分比
方波,高电平与低电平的比例,可以从+wid、-wid、+Duty、-Duty这几个参数来推算
