A. AUTOMATICALLY SEQUENCE FUNCTION

每個通道可以單獨設置快速序列，每通道最多可以建立120個點、延遲時間等，每一步階最小可設定為100us。在相同的控制模式下，可以同時進行多通道的序列控制，并模擬交換式電源供應器加載行為，這是PEL-2000A系列*而有力的特征之一，可運用在多通道輸出電源供應器的模擬。在動態模式下，負載電流或脈沖負載電阻其兩個預置準位的條件設置速度，每一步階可達25us，這通常是作為標準測試程序，以驗證負載快速變化的響應。
右上圖是一張(zhang)單通道交換式電(dian)源供(gong)應器(qi)(qi)仿真負載快(kuai)速(su)變化的(de)一個范(fan)例。透過數字示波(bo)器(qi)(qi)搭配(pei)使用電(dian)流(liu)測(ce)棒所(suo)截取到的(de)電(dian)流(liu)波(bo)形，PEL- 2000A可程(cheng)(cheng)序(xu)直(zhi)流(liu)電(dian)子負載的(de)序(xu)列編程(cheng)(cheng)功能(neng)，能(neng)夠(gou)對于交換式電(dian)源供(gong)應器(qi)(qi)進行(xing)產品的(de)性(xing)能(neng)測(ce)試
