Dynamic Signal Analyzer – VR Mobile

Description of Dynamic Signal Analyzer – VR Mobile

VR Mobile connects to an ObserVR1000 dynamic signal analyzer or VibrationVIEW for live vibration test monitoring using a phone or tablet. It also contains engineering calculators, a light strobe, a noise SPL meter, and accelerometer. All of this from your mobile device!
INCLUDED FEATURES:
Connect to nearby ObserVR1000 Dynamic Signal Analyzer & DAQ
- Setup inputs, record and monitor data.
- Live FFT Analysis
Remotely control VibrationVIEW from within the VR Mobile App (while on the same network).
- Start/Stop tests
- View graphs
- Adjust amplitude and frequency
Max Acceleration Calculator:
- Calculate the maximum amount of acceleration that a shaker (from a database) can output based on the mass added to the system.
Unit Converter:
- Convert Acceleration, Force, Mass, Velocity, and Displacement units to and from common units.
Sine Calculator:
- Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.
Shock Calculator:
- Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.
Noise Meter:
- Measure minimum, current, and maximum dB from your mobile device's microphone.
Accelerometer:
- Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes.
- Zero out acceleration to calibrate for an uneven surface.
Strobe Light and Flashlight
- Strobe your device's screen and/or flash LED from 1 - 30 Hz.
Strobing helps one to see objects vibrating too fast for the eye to see.
- Turn your device's screen and/or flash LED into a flashlight; this makes a convenient flashlight during test setups.
- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.
Contact VR:
