這NI SCXI-2000底盤最多可容納四個(gè)SCXI模塊。這底盤使用常規(guī)交流電源供電，為信號(hào)調(diào)理、供電和SCXI模塊的控制電路提供最小噪聲的環(huán)境。這通用底盤可用于當(dāng)前和未來(lái)的SCXI模塊，使其成為具有多種應(yīng)用需求的用戶的理想選擇。有許多類型的可選設(shè)備也可以與一起使用SCXI 2000放大、濾波、隔離和多路復(fù)用不同類型的信號(hào)，包括:熱電偶、電阻溫度檢測(cè)器、應(yīng)變儀、數(shù)字I/O信號(hào)、模擬輸出、電流輸入和高壓輸入。也有帶螺絲端子、BNC連接器或熱電偶插頭的電纜和端子板可用于連接用戶的模塊。

這國(guó)家儀器公司SCXI-2000底盤附帶NI-DAQ驅(qū)動(dòng)軟件。NI-DAQ有一個(gè)擴(kuò)展的函數(shù)庫(kù)，用戶可以從他們的應(yīng)用程序設(shè)置中調(diào)用。包括的一些功能有模擬輸入序列、緩沖數(shù)據(jù)采集、模擬輸出、波形生成、數(shù)字I/O、計(jì)數(shù)器/定時(shí)器操作、SCXI、RTSI、自校準(zhǔn)、消息以及獲取擴(kuò)展存儲(chǔ)器的信息。

在的前面板上鎳SCXI-2000，有狀態(tài)指示燈指定'底盤'活動(dòng)。還有一個(gè)RS-232連接器、一個(gè)電源開(kāi)關(guān)、一個(gè)指示燈、一個(gè)復(fù)位按鈕、插槽0/電源、一個(gè)背板、DIP開(kāi)關(guān)、模塊導(dǎo)軌和前螺紋條。在后面板上，有背面螺紋帶、背面連接器空間、電源輸入模塊、保險(xiǎn)絲、背板保險(xiǎn)絲、風(fēng)扇和過(guò)濾器以及電壓選擇輪。

The NI SCXI-2000 Chassis can hold four SCXI modules maximum. This Chassis is powered with regular AC power and supplies an environment with minimal noise for signal conditioning, providing power, and control circuitry for the SCXI modules. This General-Purpose Chassis can be utilized with current and future SCXI modules, making it a diverse model perfect for users with versatile application demands. There are many types of optional devices which can also be used with the SCXI 2000 to amplify, filter, isolate, and multiplex different signal types, including: thermocouples, resistance temperature detectors, strain gauges, digital I/O signals, analog outputs, current inputs, and high-voltage inputs. There are also cables and terminal blocks with screw terminals, BNC connectors, or thermocouple plugs available to link the user’s modules as well.

The National Instruments SCXI-2000 Chassis comes with the NI-DAQ driver software. NI-DAQ has an expansive library of functions that can be called upon by the user from their application programming settings. Some of the functions included are sequences for analog input, buffered data acquisition, analog output, waveform generation, digital I/O, counter/timer operations, SCXI, RTSI, self-calibration, messaging, and obtaining information to the extended memory.

On the front panel of the NI SCXI-2000, there are status LEDs which specify the Chassis’ activity. There is also an RS-232 connector, a power switch, an indicator light, a reset button, slot 0/power supply, a backplane, DIP switches, module guides, and front threaded strips. On the back panel, there are back threaded strips, a back connector space, a power entry module, a fuse, backplane fuses, a fan and filter, and a voltage selection wheel.
