【功能描述】
National Instruments NI 9234 聲音和振動(dòng)輸入模塊
NI 9234（部件號(hào)：779680-01和779680-03）聲音和振動(dòng)輸入模塊具有四個(gè)模擬輸入通道，設(shè)計(jì)用于從IEPE傳感器執(zhí)行精確測(cè)量。兩個(gè)部件號(hào)之間的唯一區(qū)別是部件號(hào) 779680-01 沒有保形涂層，但部件號(hào) 779680-03 是保形涂層。該模塊的動(dòng)態(tài)范圍為 102 dB。輸入通道采樣速率高達(dá) 51.2 kS/s。該型號(hào)的其他規(guī)格包括 24 位分辨率、50 g 沖擊和 5 g 振動(dòng)。該 設(shè)備 重 6.1 盎
， NI 9234 C 系列 模 塊 配備 了 內(nèi)置 的 抗 混疊 濾 光 器， 能夠 自動(dòng) 調(diào)節(jié) 到 用戶 指定 的 采樣 率。該 聲音 和 振動(dòng) 輸入 模 塊 兼容 單 模 塊 USB 載 體 以及 NI CompactDAQ 和 CompactRIO 硬件。NI-9234 與 這些 平臺(tái) 兼容 了 較 多 的 移動(dòng) 或 便攜式 應(yīng)用， 包括 車載 噪聲、 振動(dòng) 和 聲振 粗糙 度 測(cè)試 以及 工業(yè) 機(jī)器 狀態(tài) 監(jiān)測(cè)。此外，該模塊可以從一個(gè)平臺(tái)切換到另一個(gè)平臺(tái)，而無需進(jìn)行任何更改。
當(dāng)NI 9234模塊與NI USB-9162載體結(jié)合使用時(shí)，規(guī)格將相似。這個(gè)由兩部分組成的模塊稱為NI USB-9234。 NI USB-9234 可以 通過 USB 電纜 連接 到 計(jì)算機(jī)， 也 可以 安裝 到 面板 上。浮動(dòng)信號(hào)傳感器或以地為參考的信號(hào)傳感器也可以連接到NI USB-9234。
NI-9234使用NI-DAQmx 9.2（或更高版本）驅(qū)動(dòng)程序軟件運(yùn)行，必須先安裝該軟件。安裝軟件后，用戶需要安裝對(duì)他們選擇的應(yīng)用程序開發(fā)環(huán)境的支持，可以是LabVIEW，LabWindows/CVI，C/C++，C#或Visual Basic .NET。該設(shè)備具有 BNC I/O 連接器。

【英文介紹】
National Instruments NI 9234 Sound and vibration input modules
The NI 9234 (Part number: 779680-01 and 779680-03) sound and vibration input modules feature four analog input channels and are designed to perform accurate measurements from IEPE sensors. The only difference between the two part numbers is that part number 779680-01 does not have a conformal coating, but part number 779680-03 is a conformal coating. The module has a dynamic range of 102 dB. Input channel sampling rate up to 51.2 kS/s. Other specifications for this model include 24-bit resolution, 50 g shock and 5 g vibration. The device weighs 6.1 ounces
The NI 9234 C Series modules are equipped with a built-in anti-aliasing filter that automatically adjusts to a user-specified sampling rate. The sound and vibration input modules are compatible with single-module USB carriers and NI CompactDAQ and CompactRIO hardware. The NI-9234 is compatible with these platforms for a wide range of mobile or portable applications, including on-board noise, vibration and acoustic roughness testing and condition monitoring of industrial machines. In addition, the module can be switched from one platform to another without any changes.
When the NI 9234 module is used in combination with the NI USB-9162 carrier, the specifications will be similar. This two-part module is called NI USB-9234. The NI USB-9234 can be connected to a computer via a USB cable or mounted to a panel. Floating signal sensors or ground-reference signal sensors can also be connected to the NI USB-9234.
NI-9234 runs with the NI-DAQmx 9.2 (or later) driver software, which must be installed first. After installing the software, users need to install support for the application development environment of their choice, which can be LabVIEW, LabWindows/CVI, C/C++, C# or Visual Basic.NET. The device has a BNC I/O connector.
