  • A flexible microprocessor-based controller with simple keyboard entry of all test parameters
  • A specially designed shaker to shock and vibrate the device under test
  • An oscilloscope for visual monitoring of signals created by loose particle impacts
  • A speaker for audio monitoring of signals created by loose particle impacts
  • Intensified oscilloscope display during threshold detector output
  • An indicator lamp that lights each time a particle impact is detected
  • An indicator lamp that lights and remains lit after a particle impact signal exceeds the failure threshold level
  • Numerical display of measured shock and vibration amplitudes
  • Numerical display of programmed frequency and other test parameters
  • Automatic frequency calculation from test package cavity height per MIL-STD 883C Method 2020 requirements
