Bode100環(huán)路分析儀的主要功能是量測(cè)待測(cè)物在頻域上的特性，了解其性能及穩(wěn)定性，并可輔助控制線路的設(shè)計(jì)。其工作原理是藉由注入一個(gè)頻率變化的小信號(hào)，測(cè)出待測(cè)物在不同頻率的響應(yīng)特性。 一般工程師在設(shè)計(jì)驗(yàn)證時(shí)，都是直接測(cè)試外在的時(shí)域功能特性。例如針對(duì)電源供應(yīng)器，需要不同電壓輸出來(lái)做拉載測(cè)試，看是否會(huì)有震蕩的不穩(wěn)定情形。這種測(cè)試過(guò)程是必要的，但是不夠。并且需花用大量時(shí)間，當(dāng)線路有修改后，又得重新測(cè)試。而即使設(shè)計(jì)驗(yàn)證已經(jīng)沒(méi)有問(wèn)題，常會(huì)發(fā)生于大量生產(chǎn)時(shí)，因?yàn)槭褂昧慵恼`差，仍有少數(shù)產(chǎn)品會(huì)有不穩(wěn)定的瑕疵狀況，
這是因?yàn)樵O(shè)計(jì)時(shí)沒(méi)有正確評(píng)估系統(tǒng)的穩(wěn)定性。但這種特性無(wú)法直接由電流拉載的時(shí)域測(cè)試來(lái)得到，必須經(jīng)由Bode100環(huán)路分析儀的使用，才能得到系統(tǒng)的頻率響應(yīng)圖，來(lái)判讀出穩(wěn)定度的特性。而這種頻率響應(yīng)的測(cè)試，不僅速度快，節(jié)省大量測(cè)試時(shí)間。除了了解待測(cè)物的穩(wěn)定程度外，還可依照實(shí)際需要，再做控制線路的調(diào)整，達(dá)到設(shè)計(jì)的目的。維持良好的設(shè)計(jì)質(zhì)量，加深客戶對(duì)設(shè)計(jì)者技術(shù)的信任，增進(jìn)對(duì)產(chǎn)品的信心。尤其業(yè)界的激烈競(jìng)爭(zhēng)，及要求交期非常短的情況下，環(huán)路分析儀的分析，將有很大幫助。
另外，也可以應(yīng)用來(lái)驗(yàn)證委外設(shè)計(jì)生產(chǎn)的電源供應(yīng)器，對(duì)設(shè)計(jì)質(zhì)量來(lái)把關(guān)。 頻率響應(yīng)分析儀Bode100選，可以測(cè)試被動(dòng)組件的阻抗和頻率的特性圖，例如ESR測(cè)試，讓廠商了解生產(chǎn)的被動(dòng)組件特性是否正常，以驗(yàn)證制程是否正確。另外設(shè)計(jì)工程師可用來(lái)驗(yàn)證所使用的組件，其頻率響應(yīng)特性是否適合于應(yīng)用范圍。例如電容于低頻時(shí)是電容性，隨頻率增加會(huì)成為電阻性，再來(lái)會(huì)變成電感性。若選擇不當(dāng)，可能使用的電容卻呈現(xiàn)電感特性，線路自然無(wú)法正確運(yùn)作。當(dāng)真正了解適用頻率范圍后，選擇正確零件才能達(dá)到設(shè)計(jì)效果，不會(huì)出錯(cuò) 。
