示波器(qi)是一(yi)種用(yong)于顯(xian)示電(dian)(dian)壓信(xin)號(hao)隨時(shi)間變(bian)化(hua)的(de)(de)(de)儀器(qi)。其工作原理基于電(dian)(dian)子學中(zhong)的(de)(de)(de)“洛倫茲(zi)變(bian)換(huan)”。當一(yi)個(ge)周期性脈沖(chong)進(jin)(jin)入示波器(qi)的(de)(de)(de)輸(shu)入端時(shi)，它被轉換(huan)為電(dian)(dian)信(xin)號(hao)并加(jia)到屏(ping)幕顯(xian)像管(guan)(guan)上產生圖(tu)像。這(zhe)個(ge)過程包括三個(ge)步驟：調制、掃描和放大。首先，在觸發電(dian)(dian)路的(de)(de)(de)幫(bang)助(zhu)下，調諧部(bu)分將波形振幅(fu)與線(xian)性度進(jin)(jin)行比較(jiao)調整后得到穩定基線(xian)，然后通(tong)過鋸齒(chi)形偏轉電(dian)(dian)極施加(jia)的(de)(de)(de)直流電(dian)(dian)壓使陰極射線(xian)管(guan)(guan)的(de)(de)(de)燈絲加(jia)熱(re)發射出來的(de)(de)(de)電(dian)(dian)子束流受到板狀聚焦電(dian)(dian)視(shi)柱透鏡的(de)(de)(de)控制變(bian)得細長而(er)平行，終加(jia)速至熒(ying)光屏(ping)形成亮帶（同步輻射）。使用(yong)垂直系統(tong)和水平系統(tong)對每(mei)一(yi)行視(shi)頻數(shu)據進(jin)(jin)行匹配處理，以便每(mei)秒60幀的(de)(de)(de)畫面可(ke)在屏(ping)幕上連續播放即(ji)可(ke)完(wan)成整個(ge)操作流程。

示(shi)波(bo)(bo)器(qi)(qi)是一種用(yong)(yong)(yong)于(yu)(yu)顯示(shi)電(dian)(dian)(dian)信(xin)(xin)號(hao)波(bo)(bo)形(xing)的(de)(de)電(dian)(dian)(dian)子設(she)備。它通過將電(dian)(dian)(dian)信(xin)(xin)號(hao)轉換為模擬(ni)電(dian)(dian)(dian)壓信(xin)(xin)號(hao)，然后通過示(shi)波(bo)(bo)管(guan)或數(shu)字(zi)顯示(shi)器(qi)(qi)來顯示(shi)信(xin)(xin)號(hao)的(de)(de)波(bo)(bo)形(xing)。示(shi)波(bo)(bo)器(qi)(qi)廣泛應用(yong)(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)子工(gong)程、通信(xin)(xin)工(gong)程、計(ji)算機(ji)科(ke)學(xue)、物理(li)(li)學(xue)等領域，用(yong)(yong)(yong)于(yu)(yu)調試(shi)、測量和(he)分析各種電(dian)(dian)(dian)信(xin)(xin)號(hao)。它可以用(yong)(yong)(yong)于(yu)(yu)測量電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流、頻率、相位等信(xin)(xin)號(hao)參數(shu)，天津儀(yi)器(qi)(qi)維修(xiu)報(bao)價，也(ye)可以用(yong)(yong)(yong)于(yu)(yu)顯示(shi)復(fu)雜的(de)(de)波(bo)(bo)形(xing)和(he)信(xin)(xin)號(hao)變化。示(shi)波(bo)(bo)器(qi)(qi)可以用(yong)(yong)(yong)于(yu)(yu)檢測電(dian)(dian)(dian)路(lu)(lu)中的(de)(de)故障，也(ye)可以用(yong)(yong)(yong)于(yu)(yu)驗(yan)證電(dian)(dian)(dian)路(lu)(lu)設(she)計(ji)和(he)性能(neng)。此外，示(shi)波(bo)(bo)器(qi)(qi)還可以用(yong)(yong)(yong)于(yu)(yu)教育和(he)培(pei)訓，幫助學(xue)生和(he)工(gong)程師理(li)(li)解電(dian)(dian)(dian)信(xin)(xin)號(hao)的(de)(de)工(gong)作原理(li)(li)和(he)行為。
