Dunegan 4501 / M100 Particle Impact Noise Detection System
The Dunegan 4501 has been designed to detect loose particles in electronic components - programmable to provide speedy and precise automatic testing in accordance with MIL-STD-883C Method 2020 for hybrids and MIL-STD 750C Method 2052.
Features
- 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
- Abort function will stop the test on the first detection of a particle impact
- Keyboard lock with a fixed, code number program entry key prevents inadvertent alteration of the test program
- Test sequence program maintained in memory by battery power during primary power failure or equipment power off
- Overriding manual operation when desired
- Super low noise level for detecting micro-particles
- Simplified Sensitivity Test Unit (STU) checkout method that meets MIL-STD 883C Method 2020 and MIL-STD 750C Method 2052
