Random on Random Testing

Random-on-Random
Available as an optional test capability under RandomVIEW test module.

    Easy test entry
    Frequency/amplitude breakpoints of the background random acceleration spectrum are entered in an easy to read tabular form using either frequency and amplitude breakpoints, or by entering one endpoint and the desired dB/octave slope. Up to 1024 separate frequency/amplitude breakpoints can be entered, allowing entry of virtually any test.

    Random 'Tones'
    1 to 32 narrow spectral bands can be superimposed on the background random spectrum, and swept back-and-forth between frequencies at a user-programmable rate. The amplitude, bandwidth and frequency sweep parameters are all user programmable. Up to 200 separate frequency/amplitude breakpoints can be entered, allowing entry of virtually any test spec.

    Lines
    The controller comes standard with user-selectable 50 to 13,000 lines of control to provide you with the frequency resolution required for your test.

    Control Channels
    The control signal can be a single input channel, or configured from 2 to 128 input channels with either multi-channel averaging or optional multi-channel notching.

    Test and Level scheduling
    Tests can be scheduled to run a user-defined length of time, the spectrum level can be scaled by a specified dB-level, percentage, or scaled for a specified RMS acceleration. Level schedules can be entered to run various durations at different acceleration levels.

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

    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 intervals.

    Data plots
    Many graphical display options are available, including acceleration spectral density, output voltage spectral density, 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.
