這倪PXI-2569(零件號:778572-69)是一個100通道的通用開關模塊，包括SPST(A型)電樞轉換，非常適合自動化測試負載的中等控制。該模型包括LabVIEW和LabWindows/CVI，它們是用于信息采集和控制應用的創(chuàng)新程序開發(fā)軟件包。LabVIEW利用圖形化編程，而LabWindows/CVI改進了傳統(tǒng)的編程語言。這兩個包包含用于信息采集、儀器控制、數(shù)據(jù)分析和圖形數(shù)據(jù)顯示的廣泛庫。利用LabVIEW或LabWindows/CVI可以從根本上減少用戶信息采集和控制應用程序的開發(fā)時間。

在該模型中，每個通道通過關閉其繼電器與相應的公共接口連接。繼電器名稱取決于相應的信號名稱。例如，連接CH9和COM9的繼電器是CH9。用戶可以擁有與相應的公共資源相關聯(lián)的多個頻道。該儀器允許用戶利用驅動程序設置開關卡進行不間斷或一次性濾波。在不斷的檢查中，開關卡遍歷輸出列表，直到用戶禁用掃描。對于一次性掃描，開關卡只需瀏覽掃描列表一次。用戶也可以利用編程召喚來清除輸出列表或將其重置為開始。

這倪PXI-2569可以利用外部觸發(fā)輸入在掃描列表中的掃描設置之間前進。利用驅動軟件，用戶可以安排轉換卡從任何PXI TTL觸發(fā)線或PXI星觸發(fā)器來處理外部觸發(fā)器。另一方面，用戶可以利用軟件命令來觸發(fā)開關卡。

The NI PXI-2569 (Part Number: 778572-69) is a 100-channel, universally useful switch module including SPST (Form A) armature transfers, which is well-suited for medium-control of robotized test loads.  This model includes LabVIEW and LabWindows/CVI, which are innovative program development software bundles for information acquisition and control applications. LabVIEW utilizes graphical programming, while LabWindows/CVI improves conventional programming languages. The two bundles incorporate broad libraries for information acquisition, instrument control, data analysis, and graphical data presentation. Utilizing LabVIEW or LabWindows/CVI can fundamentally diminish the development time for the user’s information acquisition and control application.

In this model, each channel interfaces with the corresponding common by shutting its relay. The relay name depends on the corresponding signal name. For instance, the relay connecting CH9 to COM9 is CH9. The user can have numerous channels associated with the corresponding commons. This instrument allows the user to utilize the driver programming to arrange the switch card for ceaseless or one-time filtering. In ceaseless examining, the switch card goes through the output list until the user disables scanning. For one-time scanning, the switch card goes through the scan list just once. The user can also utilize a programming summons to clear the output list or reset it to the start.

The NI PXI-2569 can utilize an outside trigger input to progress between scan setups in a scan list. Utilizing the driver software, the user can arrange the change card to course the outer trigger from any of the PXI TTL trigger lines or the PXI star trigger. On the other hand, the user can utilize a software command to trigger the switch card.
