示(shi)(shi)波(bo)器(qi)(qi)是一(yi)種(zhong)用于(yu)測量和顯示(shi)(shi)電(dian)信(xin)號波(bo)形的電(dian)子設備。它(ta)由以(yi)(yi)下幾個主要部(bu)分(fen)組成：1.顯示(shi)(shi)器(qi)(qi)：用于(yu)顯示(shi)(shi)電(dian)信(xin)號的波(bo)形。顯示(shi)(shi)器(qi)(qi)通常(chang)是一(yi)個陰(yin)極射線管（CRT）或液晶(jing)顯示(shi)(shi)器(qi)(qi)（LCD）。2.信(xin)號源(yuan)：用于(yu)提供(gong)待(dai)測電(dian)信(xin)號。信(xin)號源(yuan)可(ke)以(yi)(yi)是外部(bu)設備，如(ru)信(xin)號發(fa)生器(qi)(qi)，也可(ke)以(yi)(yi)是內部(bu)電(dian)路，如(ru)電(dian)源(yuan)或放大器(qi)(qi)。3.信(xin)號調理電(dian)路：用于(yu)將待(dai)測信(xin)號轉(zhuan)換(huan)為適合顯示(shi)(shi)的信(xin)號。信(xin)號調理電(dian)路通常(chang)包(bao)括放大器(qi)(qi)、濾波(bo)器(qi)(qi)和轉(zhuan)換(huan)器(qi)(qi)等(deng)。4.控制面板(ban)：用于(yu)控制示(shi)(shi)波(bo)器(qi)(qi)的各種(zhong)參數，如(ru)垂(chui)直和水平偏移(yi)、觸發(fa)源(yuan)和觸發(fa)條件(jian)等(deng)。5.電(dian)源(yuan)：用于(yu)為示(shi)(shi)波(bo)器(qi)(qi)提供(gong)電(dian)力。

當您(nin)(nin)在選(xuan)擇(ze)四川示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)時，需(xu)要考慮(lv)以(yi)(yi)(yi)(yi)下幾(ji)個(ge)(ge)因素：1.輸(shu)(shu)入(ru)(ru)(ru)電(dian)壓范(fan)圍(wei)(wei)：您(nin)(nin)需(xu)要確(que)保示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)輸(shu)(shu)入(ru)(ru)(ru)電(dian)壓范(fan)圍(wei)(wei)符合您(nin)(nin)的(de)(de)(de)應用需(xu)求。通(tong)(tong)(tong)常，示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)輸(shu)(shu)入(ru)(ru)(ru)電(dian)壓范(fan)圍(wei)(wei)在10V至30V之間。2.輸(shu)(shu)入(ru)(ru)(ru)通(tong)(tong)(tong)道數：您(nin)(nin)需(xu)要確(que)保示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)具(ju)(ju)有(you)(you)足夠(gou)的(de)(de)(de)輸(shu)(shu)入(ru)(ru)(ru)通(tong)(tong)(tong)道數，以(yi)(yi)(yi)(yi)便同時記(ji)(ji)錄多(duo)(duo)個(ge)(ge)信號。3.采(cai)樣率和(he)(he)分(fen)辨(bian)率：示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)采(cai)樣率和(he)(he)分(fen)辨(bian)率是(shi)衡量其性能(neng)(neng)(neng)的(de)(de)(de)重(zhong)要指標。高采(cai)樣率和(he)(he)分(fen)辨(bian)率可以(yi)(yi)(yi)(yi)提供的(de)(de)(de)波(bo)(bo)(bo)形(xing)記(ji)(ji)錄和(he)(he)分(fen)析。4.存(cun)儲(chu)(chu)深度：示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)存(cun)儲(chu)(chu)深度是(shi)指其能(neng)(neng)(neng)夠(gou)記(ji)(ji)錄的(de)(de)(de)數據量。您(nin)(nin)需(xu)要確(que)保示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)能(neng)(neng)(neng)夠(gou)滿足您(nin)(nin)的(de)(de)(de)存(cun)儲(chu)(chu)需(xu)求。5.功(gong)(gong)能(neng)(neng)(neng)：您(nin)(nin)需(xu)要確(que)保示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)具(ju)(ju)有(you)(you)您(nin)(nin)需(xu)要的(de)(de)(de)功(gong)(gong)能(neng)(neng)(neng)，例如觸(chu)發器(qi)(qi)(qi)(qi)(qi)、波(bo)(bo)(bo)形(xing)監(jian)視器(qi)(qi)(qi)(qi)(qi)、函數發生(sheng)器(qi)(qi)(qi)(qi)(qi)等(deng)。基(ji)于以(yi)(yi)(yi)(yi)上(shang)因素，您(nin)(nin)可以(yi)(yi)(yi)(yi)選(xuan)擇(ze)一些(xie)品牌(pai)和(he)(he)型(xing)號的(de)(de)(de)示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)，天(tian)津儀器(qi)(qi)(qi)(qi)(qi)維修報價，例如：1.Agilent4194A：這是(shi)一款示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)，具(ju)(ju)有(you)(you)多(duo)(duo)個(ge)(ge)輸(shu)(shu)入(ru)(ru)(ru)通(tong)(tong)(tong)道、高采(cai)樣率和(he)(he)分(fen)辨(bian)率、大存(cun)儲(chu)(chu)深度以(yi)(yi)(yi)(yi)及(ji)多(duo)(duo)種功(gong)(gong)能(neng)(neng)(neng)。2.RigolDSO1012：這是(shi)一款入(ru)(ru)(ru)門級示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)，具(ju)(ju)有(you)(you)兩(liang)個(ge)(ge)輸(shu)(shu)入(ru)(ru)(ru)通(tong)(tong)(tong)道、高采(cai)樣率和(he)(he)分(fen)辨(bian)率，但存(cun)儲(chu)(chu)深度較(jiao)小(xiao)。3.OmegaVSA3024：這是(shi)一款多(duo)(duo)功(gong)(gong)能(neng)(neng)(neng)示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)，具(ju)(ju)有(you)(you)多(duo)(duo)個(ge)(ge)輸(shu)(shu)入(ru)(ru)(ru)通(tong)(tong)(tong)道、高采(cai)樣率和(he)(he)分(fen)辨(bian)率、大存(cun)儲(chu)(chu)深度以(yi)(yi)(yi)(yi)及(ji)觸(chu)發器(qi)(qi)(qi)(qi)(qi)和(he)(he)波(bo)(bo)(bo)形(xing)監(jian)視器(qi)(qi)(qi)(qi)(qi)等(deng)功(gong)(gong)能(neng)(neng)(neng)。以(yi)(yi)(yi)(yi)上(shang)是(shi)一些(xie)常見的(de)(de)(de)示(shi)(shi)波(bo)(bo)(bo)器(qi)(qi)(qi)(qi)(qi)品牌(pai)和(he)(he)型(xing)號，您(nin)(nin)可以(yi)(yi)(yi)(yi)根(gen)據自己(ji)的(de)(de)(de)需(xu)求和(he)(he)預算進行(xing)選(xuan)擇(ze)。

示(shi)波(bo)器是(shi)一(yi)種用于顯(xian)示(shi)電(dian)(dian)壓信(xin)號隨時間變化的儀器。其工作原理基(ji)于電(dian)(dian)子學(xue)中的“洛倫茲(zi)變換(huan)”。當一(yi)個(ge)(ge)周期性(xing)脈沖進(jin)(jin)(jin)入電(dian)(dian)路時，它會(hui)(hui)激(ji)發(fa)出與(yu)原輸(shu)入波(bo)形相同但相位(wei)相反的電(dian)(dian)場或磁場；這(zhe)兩(liang)個(ge)(ge)電(dian)(dian)磁場的疊(die)加將產生一(yi)個(ge)(ge)新的、等幅(fu)而反向（即(ji)180°）相位(wei)的輸(shu)出波(bo)形。這(zhe)個(ge)(ge)過(guo)程(cheng)被(bei)稱為調(diao)制。四川示(shi)波(bo)器的具體操作步(bu)驟如下(xia)：首(shou)先(xian)接(jie)通(tong)電(dian)(dian)源并預熱(re)幾分鐘后進(jin)(jin)(jin)行開(kai)機準備。在屏(ping)幕上(shang)會(hui)(hui)顯(xian)示(shi)出一(yi)條垂直(zhi)基(ji)線和一(yi)個(ge)(ge)水(shui)平掃描線框。然后根(gen)據需要(yao)選擇適(shi)當的通(tong)道Ⅰ/Ⅱ和合適(shi)的靈敏度及觸發(fa)方式設置。通(tong)過(guo)鍵盤(pan)上(shang)的功能鍵對屏(ping)幕的各種參數進(jin)(jin)(jin)行調(diao)整(zheng)即(ji)可完成(cheng)整(zheng)個(ge)(ge)調(diao)試流程(cheng)。
