VTI High Density Digitizers

VTI Instruments (formely VXI/Agilent/HP)

The Modal Shop now offers the SentinelEX Integrated Data Acquisition product family from VTI building upon the industry standard VXI platform. The SentinelEX family leverages the LXI and PXIe standards. LXI is the largest instrumentation standard for rack mount programmable instruments, whereas PXIe is the new modular card standard based on the PCI Express bus. Combining the power of both of these standards allows the SentinelEX family to scale from a handful to thousands of channels of mixed DAQ and satisfy applications from low-speed temperature to high-speed NVH within one family.  See below for equipment details.

An industry standard, offering a high-performance system architecture for demanding mechanical, sound and vibration data acquisition applications. Features parallel processing architecture and a dedicated high speed local bus for fast data transfer to the host computer. The Modal Shop offers a variety of VXI cards, mainframes, and accessories (see below for details).  Multiple cards can be added to expand to the channel count desired. We also offer VT324xA breakout boxes that accept voltage inputs or power traditional ICP® transducers. For a general overview of the hardware, click here.

DAC Express data recording/logging software is also available with VXI equipment. The software comes prepared on a system controller.  Features include:

  • Combine synchronized multichannel analog, digital, and frequency measurements
  • Combine dynamic and static measurements
  • File sizes up to 2 Giga samples per channel
  • Real-time display customizes easily to optimize visualization
  • Easily export data to MATLAB®, Excel® and other standard programs

*Grounding Notes:
Each connector on the breakout box has a small manual switch next to it. When this switch is in the “GND” position the outer shell of the connector is grounded to the chassis ground of the VXI mainframe. When it is in the “DIFF” position it is not grounded to the mainframe and will float if not grounded elsewhere in the system (such as at the sensor). The connector shell should not be allowed to float: if the switch is in the “DIFF” position the shell should be grounded elsewhere in the system.
