Datasheet

The Spectral Dynamics SD Felix is a particle impact noise detector that tests for loose particles using reliable internal electronic components such as relays, transistors, hybrids, integrated circuits, and switch particles. The SD Felix combines sensors like ultrasonic (155kHz) that monitor shaker motion with feedback control to correct for changes that happen in test conditions. The Spectral Dynamics SD Felix uses computer technology that controls motion and allows technicians to program motion including shock and vibration at precise levels to simulate a whole range of testing needs. The Spectral SD Felix uses four unique channels for data collection and all four use the same clock to digitize the data at 2.5MSamples per second. The SD Felix’s four unique channels include a high-speed acoustic channel, vibration channel, shock channel, and digital output channel. The SD Felix’s unique features are great for testing electronic components for cardiac pacemakers, spacecraft, or undersea cables.
