Field Data Replication

Field Data Replication. Play back your collected data in real-time (time history).

    Reproduce your waveform
    Take your field acceleration measurements, and reproduce them on your shaker in your test lab. There is no need to try to approximate your field environment through the approximations inherent in the standard random, sine, or shock tests.

    Field Data Replicator Reference (Output) VR9401
    Play any uncompensated reference waveform fully synchronized with the control waveform. Useful for providing reference waveforms to a spectrum analyzer for external verification of results. Also useful for providing a pre-recorded trigger signal (e.g. tachometer, cylinder firing, etc.) synchronized to the vibration. Can also be used for synchronizing additional environmental factors (e.g. motor RPM, temperature, etc.) with the recorded vibration.

    Data Import
    Import waveforms from data recorders using an analog input, or import from digital wave or text files. Waveforms can be up to 45 hours long at a 26,000 Hz sampling rate (with VR9403 High Frequency option), or up to 1 year long at a 100 Hz sampling rate.

    Test and Level scheduling
    The test can be set to reproduce the waveform for a specified duration. The waveform can be scaled up or down by any factor to get the test intensity you desire. Tests can be programmed to run for various periods at different intensity levels. The amplitude can be changed while the test is running.

    Multiple shakers
    From 1 to 4 control loops can be run simultaneously to independently control up to 4 shakers with 4 separate waveforms.

    Configurable safety limits
    To protect your test article and shaker system, configurable acceleration and drive limits can be set by the user. The control input is also verified against shaker force ratings.

    The controller automatically equalizes the response of the shaker/fixture/product prior to running the test. This equalization can be memorized and stored with the test to quickly start a test at full equalized level. The frequency range of the output signal is configurable, and a frequency band can even be notched out of the signal.

    Data Storage
    All of the test data can be stored to the disk for later retrieval. Data storage can be done manually, or programmed to automatically save at user-defined pulse intervals.

    The controller comes standard with 50 to 6500 lines of control to provide you with the frequency resolution required for your test.

    Data plots
    Many graphical display options are available, including acceleration and drive voltage vs. time or frequency, and channel-to-channel transmissibility. Graphs can be easily auto-scaled or zoomed, and cursors displayed. Data and text annotations can be easily placed on the graphs, with data values updated live as the data changes.

    Frequency Range
    Select the lower and upper frequency of operation while the test is running (up to 4,900Hz).

    High Frequency (Optional) VR9403
    Extends your operational frequency to 20,000Hz. (*Note - requires export license for end users outside of the USA)

    Notch Filter
    Apply a notch filter while the test is running.

    Includes EditVIEW
    For editing your collected data, useful when the data has long "quiet" periods that are not wanted in the final data file.
