Test Modules

SINE – Run swept and/or fixed-frequency sine wave vibration tests, with control of acceleration, velocity, and displacement.

SINE ON SINE – Run mixed-mode tests with up to 32 sine tones simultaneously.

RANDOM – Run Controlled spectrum random tests (tests with a spectrally shaped gaussian amplitude distribution).

iDOF® – Prevent under or over testing on high value products where tight tolerances and short duration random testing is required.

SINE ON RANDOM – Run mixed-mode tests with sine tones superimposed on a random background.

RANDOM ON RANDOM – Run controlled spectrum random tests with swept random “tones” superimposed on a random background.

KURTOSION® – Re-introduce the high acceleration peaks back into your random vibration tests. Our patented -solution to when your in-service vibration environment is not Gaussian.

RANDOM IMPORT – Import your time-based vibration data recording and convert to a power spectral density curve with breakpoint table.

FATIGUE DAMAGE SPECTRUM – Measure your products fatigue and calculate its lifespan. Commonly used life acceleration techniques are applied to shorten test time.

SHOCK – Run standard classical shock pulses as well as (optional) user-defined or SRS synthesized transient pulses.

SRS – Perform Shock Response Spectrum (SRS) analysis. Run a shock pulse defined by a frequency vs. G peak table. Many different waveform synthesis generation techniques included.

TRANSIENT CAPTURE – Capture a transient waveform for post process. Use alone for data acquisition, or with SRS for Shock Response Spectrum analysis.

FIELD DATA REPLICATION – Reproduce, in your test lab on your shaker, the actual acceleration waveforms you measure in the field. The controller automatically compensates for shaker and fixture response.

EARTHQUAKE – Run a shock pulse defined by a frequency vs. G peak table. Many different waveform synthesis generation techniques included.

HALT/HASS Vibration Table Validation:

What is the true Magnitude of Force the Device Under Test Experiences

  • Determine how the energy is distributed across the table compared to the control accelerometer located at the center bottom of the table
  • Validate the Power Spectral Density in each Quadrant of the Table
  • Validate the proper location to place the Device Under Test
  • Validate the proper fixture configuration for correct energy transfer to the Device Under Test
  • Validate detailed vibration data of subcomponents throughout the Device Under Test
  • Identify unexpected movement of electronic components from resonance frequencies
  • Compare the Calibration data with Validation Data
  • We use ISO 17025 Calibrated Vibration Research VR 9500 controllers – 16 channels
  • We use ISO 17025 Calibrated Single Axis and Triaxial Accelerometers to capture data
