Sine Reduction test runs so that the Digital Signal Analyzer (DSA) is synchronized to a Vibration Control System (VCS). By doing this, more processing channels can be arranged on the Sine Reduction system, and work simultaneously with the swept sine test. COLA (Constant Output Level Adaptor) signal is crucial for this type of test. Two instruments are synchronized through controller’s COLA output signal. The COLA signal is a constant voltage sine wave which frequency tracks the Drive signal frequency during the Sine Control test. Sine Reduction test is widely used for the satellite testing, and typically, hundreds of input channels are required.
