Data Acquisition Systems

National Instruments PXI-1036 data acquisition platform

PXI-1036 system combines a 6-slot PXI backplane with a structural design for maximum usability in a wide range of applications.

The system can be controlled via laptop or PC computers through controller modules PXI-8310 and PCI-8360 respectively.

It has 8 simultaneously sampled analog inputs with 16-bit, 500 kS/s per channel captured by NI DAQ module PXI-6123, and 8 high-speed analog outputs with 1 MS/s per channel and 16-bit resolution generated by NI DAQ module PXI-6733.

Sound and vibration data acquisition is available via high-accuracy DAQ module PXI-4496 with the capability of 16 simultaneous analog inputs at 24-bit resolution and 204.8 kS/s maximum sampling rate.

CompactRIO

CompactRIO system is a real-time based control and monitoring system. With highly integrated software, extensive I/O, and a range of embedded controllers across a variety of form factors, CompactRIO is a single device that can meet a variety of needs under different circumstances. The system features a 1.91 GHz Quad-Core CPU with Kintex-7 325T FPGA. It also includes data acquisition modules such as:

  • one +/-20 mA, 16-Bit, 200 kS/s, 8-Ch AI Module

  • two +/-10 V, 16-Bit, 100 kS/s/ch, 4-Ch AI Module

  • one TTL Digital Input/Output Module

  • one C Series Sound and Vibration Input Module

  • one 4-Ch Voltage Output, ±10V, ch-ch ISO

  • one 16-ch TC, 24-bit, 75 S/s AI module

  • USB and Ethernet connection for vision sensors

PCI Data Acquisition Systems

PCI Data Acquisition Systems such as PCI-6036E, PCI-6025E, PCIE-6253, and PCIE-6512. PCI and PCI Express, as the general PC I/O bus, can maintain software flexibility while offering up to 250 MB/s of bandwidth per direction per lane. With the wide range of DAQ equipment available in AMPL, different signal types can be generated and measured accurately, thus facilitating the research progress and validation of various proposed process and system models.
