這PXI-6250(零件號:779116-01)是一個虛擬儀器 多功能輸入輸出模塊以無與倫比的精度和快速的測試速度創(chuàng)造。這種高速m系列模塊結(jié)合了先進(jìn)的亮點(diǎn)，如NI-STC 2框架控制器，NI-PGIA 2可編程增強(qiáng)器，和NI-MCal校準(zhǔn)技術(shù)，以擴(kuò)大執(zhí)行和準(zhǔn)確性。這倪PXI-6250內(nèi)置一個本地可用的NI-PGIA 2放大器，用于在高掃描速率下快速建立時間，即使以較高的速率估計所有通道，也能保證16位分辨率。該模塊也有兩年的校準(zhǔn)間隔，這意味著它應(yīng)該至少每兩年進(jìn)行一次外部校準(zhǔn)。

在輸入范圍相似的通道之間進(jìn)行檢查時，建立時間會隨著通道之間的當(dāng)前步長而增加。如果用戶知道他們信號的正常輸入范圍，那么他們可以將具有相對預(yù)期范圍的信號聚集在他們的掃描列表中。對于10 V以上的電壓輸入或傳感器測量，用戶應(yīng)使用信號調(diào)理附件。緩沖的采集數(shù)據(jù)從鎳PXI-6250多功能輸入/輸出模塊在將板載FIFO存儲器傳輸?shù)綉?yīng)用存儲器之前，利用DMA或中斷將其傳輸?shù)絇C緩沖區(qū)。

The PXI-6250 (Part Number: 779116-01) is a PXI Multifunction I/O Module created for unrivaled precision at quick testing rates. This high-speed M Series module incorporates advanced highlights, such as the NI-STC 2 framework controller, NI-PGIA 2 programmable intensifier, and NI-MCal calibration technology to expand execution and exactness. The NI PXI-6250 has a locally available NI-PGIA 2 amplifier intended for quick settling time at high scanning rates, guaranteeing 16-bit resolution even when estimating all channels at superior rates. This module also has a two year calibration interval, meaning it should be calibrated externally a minimum of every two years.

When checking between channels with a similar input range, the settling time increments with the present step between the channels. If the user knows the normal input range of their signals, then they can aggregate signals with comparative expected ranges together in their scan list. The user should utilize signal conditioning accessories for voltage inputs over 10 V or sensor measurements. Buffered acquisition data is moved from the NI PXI-6250 Multifunction I/O Module’s onboard FIFO memory to a PC buffer by utilizing DMA or interrupts before it is transferred to the application memory.

This PXI Multifunction I/O Module can be used with NI-DAQmx driver software, LabVIEW SignalExpress LE data-logging software, and the Measurement & Automation Explorer configuration utility. The digital lines on the PXI-6250 module can drive 24 mA for actuator and relay control. When the user clocks the module’s digital lines at 10 MHz, then they can utilize the lines for pulse-width modulation to control pumps, valves, lamps, fans, and motors. The NI PXI-6250 can also be utilized with NI Analog Output Devices for 64 or more loops.
