National Instruments 776572-1600 Data Acquisition Module
The National Instruments 776572-1600 provides a DAQ (Data Acquisition) function within a single board for controlling the SCXI signal conditioning chassis. In addition to providing DAQ functionality, this 16-bit board also serves as a controller for all SCXI analog input modules, analog output modules, digital I/O modules, and switching modules. By routing conditioned analog inputs from these modules, the 776572-1600 can digitize these signals for PC-based acquisition via its built-in USB 2.0 Full Speed interface, allowing for remote operation up to 150 feet from the chassis.
Besides its ability to operate remotely, the SCXI-1600 part number 776572-1600 can be connected to any available USB port (USB 1.0, USB 1.1). The 776572-1600 also provides high resolution through its use of a 16-bit successive approximation analogue-to-digital converter (ADC) with a ±10V range and four selectable gains (0.5, 1, 10, and 100) to accommodate signals ranging from millivolts to volts. To maintain throughput during acquisition operations, the 776572-1600 has a 4,096-sample first-in, first-out (FIFO) buffer and a 512-word configuration memory. In order to preserve accuracy during acquisition, the module uses an internal calibration source and an External Calibration (EXTCAL) BNC connector to apply a precise voltage reference instead of relying on the analogue input as a reference. Two additional BNC connectors are provided for connecting a digital trigger and external clock for synchronisation purposes. After calibration, post-calibration gain error is as low as 74 ppm at unity gain. Offset errors are similarly minimized after calibration.
NI-DAQmx Version 7.3 software provides support for the entire family of NI-DAQmx boards, including the NI 776572-1600. Using the Measurement & Automation Explorer Utility provided by NI-DAQmx Software allows users to easily configure their systems using the graphical user interface provided by the software. Additionally, NI-DAQmx software allows integration with popular programming environments such as LabVIEW, LabWindows/CVI, and Measurement Studio. Examples and test panels are also provided in NI-DAQmx software to expedite the setup of your system. Some advanced features of NI-DAQmx software include multidevice synchronization, networked measurements, and DMA data management. Overvoltage protection on this board protects against voltages as high as ±25 volts when the board is connected to power and ±15 volts when it is disconnected from power. With its combination of precision and channel density, the SCXI-1600 776572-1600 is ideal for use in industrial automation applications, laboratory testing applications and remote sensing applications requiring the capture of analog inputs in large quantities.
