National Instruments PCI-MIO-16XE-50 Multifunction DAQ

Featured with 20 kS/s (guaranteed) sampling rate and successive approximation type of analog-to-digital converter the National Instruments PCI-MIO-16XE-50 (Part Numbers: 777385-01 and PCI-6011E) is a Multifunction DAQ. This device is a multifunction digital, analog, and timing I/O board that is compatible with PCI bus computers. The NI PCI-MIO-16XE-50 has 16 analog input channels, 2 analog output channels, and 3 DMA channels. The two voltage channels are equipped with double-buffered, multiplying digital-to-analog converters.

The interface circuitry of this DAQ consists of a digital control logic chip and a PCI interface chip. The PCI interface chip enables the unit to communicate with the host PCI bus. The digital control logic chip facilitates communication between the rest of the board and the PCI interface chip. The NI PCI-MIO-16XE-50 is easy to configure since it comes without switches and jumpers. Because it is a PCI Specifications 2.0 compliant device, the interrupt level and the base memory address remain stored inside the PCI interface chip.

This plug-and-play data acquisition device comes equipped with a programmable gain instrumentation amplifier or PGIA. The PGIA amplifies the analog input signal by applying gain. In addition, this feature enables the user to select the input signal’s polarity. The National Instruments PCI-MIO-16XE-50 comes equipped with a dedicated timing core for its two analog output channels. Each analog output channel comes with a 12-bit DAC, an onboard voltage reference, and an amplification stage. Moreover, the analog output channels have a reference source, programmable polarity, FIFO buffer, and re-glitching circuitry.
