這SCXI-1129(零件號:776572-29)是一款256交叉點高密度矩陣模塊。該模塊在SCXI平臺上提供最大4 x 64雙線開關(guān)矩陣配置。這NI SCXI-1129矩陣/多路復(fù)用器開關(guān)模塊可額外用作四個4 x 16雙線矩陣；兩個4 x 32雙線矩陣；或者兩個8 x 16雙線矩陣。標(biāo)準(zhǔn)矩陣語言通過矩陣包含的行數(shù)和列數(shù)來定義矩陣。使用端子板時SCXI-1129模塊可以配置為多個矩陣。

這SCXI 1129模塊在低電壓和高電壓下都能正常工作。對于低壓測量，該模塊利用具有%3C 9 V熱偏移的繼電器來保證精確測量。這矩陣/多路復(fù)用器開關(guān)模塊支持帶有特定適配器的模擬總線，即模塊背面SCXI-1357/1358套件中的高壓模擬總線背板適配器。該適配器使用戶能夠擴(kuò)展高壓模擬總線背板適配器，而無需復(fù)雜的布線。如果用戶將幾個模塊連接到高壓模擬總線背板適配器，則無需外部行或列連接器即可擴(kuò)展矩陣尺寸。SCXI-1129模塊可與下列端子塊之一一起使用:SCXI-1336、SCXI-1333、SCXI-1335、SCXI-1337、SCXI-1334或SCXI-1339。

當(dāng)用戶安裝時鎳SCXI-1129SCXI機(jī)箱中的模塊，最右邊的插槽(從前面觀察機(jī)箱時)必須是最初填充的插槽。然后，用戶可以繼續(xù)用下一個填充左邊的槽SCXI-1129。其他SCXI模塊可以從左向右加載。

The SCXI-1129 (Part Number: 776572-29) is a 256 crosspoint high-density Matrix Module. This module offers a 4 x 64, 2-wire switch matrix configuration maximum on an SCXI platform. The NI SCXI-1129 Matrix/Multiplexer Switch Module can additionally function as four 4 x 16, 2-wire matrixes; two 4 x 32, 2-wire matrixes; or two 8 x 16, 2-wire matrixes. The standard matrix language defines matrixes by the quantity of rows by the quantity of columns they comprise. With terminal blocks, the SCXI-1129 module can be configured as a multitude of matrixes.

The SCXI 1129 module is created to function well at low and high voltages. For low-voltage measurements, this module utilizes relays with < 9 μV thermal offset to guarantee precise measurements. This Matrix/Multiplexer Switch Module supports the analog bus with a specific adapter, the high-voltage analog bus backplane adapter in the SCXI-1357/1358 kit, at the back of the module. This adapter enables the user to expand the high-voltage analog bus backplane adapter without the necessity of complex wiring. If the user links several modules to the high-voltage analog bus backplane adapter, then they can expand the matrix size without the need for external row or column connectors. The SCXI-1129 module can be utilized with one of the following terminal blocks: the SCXI-1336, SCXI-1333, SCXI-1335, SCXI-1337, SCXI-1334, or SCXI-1339.

When the user is installing the NI SCXI-1129 module in an SCXI chassis, the farthest right slot (when the chassis is observed from the front) must be the initial slot filled. Then, the user can proceed filling the slot to the left with the next SCXI-1129. Other SCXI modules can be loaded from left to right.
