這PXI國家儀器公司-2799(零件號:782359-01) 是一款單刀雙擲繼電器(SPDT)通用開關(guān)模塊，用于在自動化測試應(yīng)用中路由RF或微波信號。NI-SWITCH驅(qū)動程序軟件集成了一個智能軟前板，提供了完整的開箱即用功能。這種直觀的軟前板使用戶能夠配置交換機(jī)拓?fù)浣Y(jié)構(gòu)，并通過簡單的點(diǎn)擊來更改交換機(jī)關(guān)聯(lián)。此外，調(diào)試驅(qū)動程序會話模式可用于在自動評估過程中篩選和調(diào)試交換機(jī)。例如，用戶可以篩選哪些信號路徑是活動的，哪些單獨(dú)的繼電器是打開/關(guān)閉的，以及每個繼電器的使用頻率。

盡管NI-SWITCH驅(qū)動程序提供了編程交換機(jī)活動所需的所有底層功能，但Switch Executive是一種用于智能交換機(jī)管理和路由的應(yīng)用軟件，它加快了復(fù)雜交換機(jī)框架的開發(fā)并簡化了維護(hù)。點(diǎn)擊式圖形排列和自動路由功能使規(guī)劃交換機(jī)框架變得簡單。利用本能的通道別名和自動路由功能，可以輕松設(shè)計交換機(jī)系統(tǒng)。通過將其框架與TestStand、LabVIEW、LabWindows/CVI和Measurement Studio集成，用戶可以節(jié)省時間并增加測試代碼的重用。

這鎳PXI-2799射頻繼電器模塊具有框架模塊，可以作為構(gòu)建模塊來進(jìn)行更大的安排，這遠(yuǎn)遠(yuǎn)超出了單個模塊的度量。列擴(kuò)展是在至少兩個或更多矩陣模塊之間連接每一行的過程，在擴(kuò)展的框架內(nèi)充分加倍列的數(shù)量。

The National Instruments PXI-2799 (Part Number: 782359-01) is a single-pole, double-throw relay (SPDT) general-purpose switching module for routing RF or microwave signals in automated test applications. The NI-SWITCH driver software incorporates an intelligent soft front board for full out-of-the-box functionality. This intuitive soft front board enables the user to configure the switch topology and change switch associations with a simple click. In addition, the Debug Driver Session mode can be used to screen and debug the switch amid automated estimation. For instance, the user can screen which signal paths are active, which individual relays are open/closed, and how frequently each relay has been utilized.

While the NI-SWITCH driver gives all the low-level usefulness required to program switch activities, Switch Executive is an application software for intelligent switch management and routing that quickens development and simplifies maintenance of complex switch frameworks. The point-and-click graphical arrangement and automated routing abilities make it simple to plan a switch framework. Utilizing instinctive channel aliases and automatic routing capabilities make it easy to design a switch system. The user can save time and increment test code reuse by integrating their framework with TestStand, LabVIEW, LabWindows?/CVI, and Measurement Studio.

The NI PXI-2799 RF Relay Module has framework modules that can serve as building blocks for making bigger arrangements that are well beyond the measure of a single module. Column extension is the process of interfacing each row between at least two or more matrix modules, adequately doubling the quantity of columns inside the extended framework.
