Vibration Control
Sine Vibration Control
Sine control is one of the two basic and most common excitation modes for Environmental Shaker testing. This control mode performs real-time closed-loop control of swept sine vibration.

m+p Dynamic Signal Analyzer SO Analyzer - Measuring and monitoring DC signals for functional testing
Sine Dwell Set-Up (incl. Resonance Search, Tracking and Phase Lock
- Specifications as per Swept Sine
- Dwell schedule table allows 50 dwell points to be defined
- Each dwell can be a fixed frequency, fixed phase, peak amplitude search and track or defined phase search and track
- Each dwell independently defines control (ref) and measurement channels
- Dwell at each point for user-selectable seconds, minutes or cycles
- User-controlled measurement data storage rate
Sine Displacement and Velocity Control
- For sine testing starting at very low frequencies, displacement transducers can be used
- At a defined frequency, the control changes automatically from displacement transducer to accelerometer transducer
Sine Data Reduction
- Track and online analysis of taped swept sine data using the COLA signal
- Evaluation and storage of the taped signals on a second vibration control system during the test run
- Sine testing is used for proving product reliability and for structural resonance search in all kind of applications such as automotive, electronics, aerospace, consumer products and military
