Overview

The UC-SDRL Data Acquisition Project is the subject of the current UC-SDRL Consortium focus.  Consortium membership in this project is currently being solicited.  The goal of the Data Acquisition Project is to provide a data acquisition environment that is specialized to the area of structural dynamics while also providing basic measurement capability. 

The UC-SDRL Data Acquisition Project will develop a Toobox that will provide a flexible environment for acquiring time domain data from VXI Technology data acquisition modules (compatible with HP/Agilent 143x data acquisition cards) directly into MATLAB.  In many ways, the Toolbox will operate in a similar fashion to the historic HP-5451-C Fourier Analysis System but all operations on the data will take place in MATLAB. This flexible environment will involve a unique data management structure, currently in use in X-Modal II, in a windows (Windows XP, Windows VISTA) environment programmed in MATLAB Graphic User Interface (GUI) script or shell. The MATLAB script/function programming capability will provide the user with the ability to use MATLAB to process the time data into any time or frequency domain functions required by the user. The Toolbox will load/store data using Universal File formats, including the relatively new Binary Universal File format (UFF-58b), as well as compatible Matlab file structures (*.mat).

Hardware Requirements (Minimum)

The UC-SDRL Data Acquisition Toolbox will be compatible with both standalone or VXI imbedded PC and HP-UX workstations with one of the following hardware specifications:

  • PC Workstation, 1 Gb RAM (minimum), Firewire (IEEE 1394) or Internet Interface

The UC-SDRL Data Acquisition Toolbox is compatible with VXI Technology hardware with the following hardware specifications:

  • VXI TechnologyMainframe (VT-1401-A or compatible equivalent)
  • VXI Technology IEEE 1394 Interface (VT xxxx-A)
  • VXI Technology 16 Channel Data Acquisition Module (VT-1432-A/B or compatible equivalent)
  • VXI 8 Channel Data Acquisition Module (VT-1432-A or compatible equivalent)
  • VXI Arbitrary Function Generator (VT-1343-A or compatible equivalent)

Software Requirements

The UC-SDRL Data Acquisition Toolbox software package is written in the MATLAB programming language which means that the same MATLAB script will be operational in several compute environments. The general requirements are one or more of the following software specifications:

  • Windows XP, Service Pack 2
  • Windows VISTA
  • LINUX
  • MATLAB (Version 2006a or later)

License Requirements

The UC-SDRL would grant a license to use the UC-SDRL Data Acquisition Toolbox, to anyone requesting, once the Toolbox is developed.  The COnsortium membership will have special rights to use the Toolbox before the Toolbox is available to the general public. The license to use the UC-SDRL research software is a license in perpetuity but does not include any warranty of the software, does not give permission to further distribute the Toolbox, does not allow any commercialization of the Toolbox and will require a Distribution/Maintenence Fee beyond the first year of use. Please see details about the UC-SDRL Research Software License on other pages of this Internet site.


 

Distribution Fee:

While the license to use the UC-SDRL Data Acquisition Toolbox will be provided free of charge, there is an annual Distribution/Maintenance Fee  to cover costs of media and personnel and the cost of maintaining the software as Matlab updates to later versions. This Fee covers an initial distribution and any major revisions for a period of one year. Only one copy and form of media will be provided per license to the contact personnel identified in the license. Further updates/revisions will be made available, after the one year period, based upon payment of annual yearly Distribution/Maintenance Fee.  Subsequent Distribution/Maintenance Fees are not required to continue to operate the current configuration of theToolbox but may be required for Operating System or Matlab updates.  Distribution/Maintenance Fees are subject to change.

Distribution Deliverables::

The deliverables include ASCII text form of all MATLAB scripts, and Encapsulated Post Script (EPS) form of all documentation.

Distribution Media:

Software will be provided electronically over the Internet via FTP.  Availability via CD or DVD is possible upon request.

Documentation:

Documentation and on-line help will be provided electronically from within the UC-SDRL Data Acquisition Toolbox.

Training:

Installation assistance and/or minor questions can be answered via telephone, E-Mail, or FAX. If more detailed installation or training is required, research assistants from the UC-SDRL can be hired as consultants (approximately $300-500 per day plus expenses) to provide on-site assistance.

Initial Capability:

Initial UC-SDRL Data Acquistion Toolbox capabilities are not guaranteed but are being considered as follows:

  • Time Data Capture:
  • Multiple Input, Multiple Output (MIMO) Power Spectrum:
  • Multiple Input, Multiple Output (MIMO) Frequency Response Functions:
  • Multiple Reference Impact Testing (MRIT):

Future MATLAB Toolbox applications are envisioned in the following areas:

  • Experimental Modal Analysis:
  • Nearfield Acoustic Holography (NAH):
  • Rotating Equipment Analysis:

Availability:

The UC-SDRL Data Acquisition Toolbox is not currently available.  Many of the capabilities of the Toolbox already have been developed in stand-alone form but are not integrated into a single, user-friendly Toolbox.  An initial version of the Toolbox is in Alpha development. This version is not yet available but can be used to demonstrate functional concepts.
