Sine Vibration Control
Sine control creates excitation with analog-quality drive signal and user-programmable sweep parameters. This test profile is particularly useful for studying the structural dynamics of the device under test, as it enables accurate measurement of dynamic response at resonances. Since sine control concentrates all the vibration energy at a single frequency,
