Sine Oscillator is a diagnosis tool with manual control to the sine output while the system displays various time signals and frequency spectra. Users can enable random excitation as a checkup function. Tracking filters are applied to each input channel to extract the signals at a sweeping frequency. When the close-loop option is enabled, the Sine Oscillator is essentially a limited sine controller with more manual control functions. Control Parameters The Sine Oscillator mode of the Swept Sine vibration test allows the output sine wave to be manually controlled by the user. The controllable parameters include frequency, amplitude, sweep rate, frequency limits and direction. When being manually controlled, the sine output is not under closed-loop control as it is during a regular swept-sine test. Closed-loop control can also be turned on to function as a simple sine controller. Frequency Range: up to 46 kHz Sweeping Rate: Log (Oct/Min): 0.001 to 120; Log (Dec/ Min): 0.001 to 40; Linear (Hz/Sec): 0.001 to 120 Sweep Rate Control: Oct/Min, Hz/Sec, Dec/Min, Sweeps/Min, Sweep Duration/Sweeps Spectrum Display Resolution: 256 to 4096 Tracking Filters: proportional: 7% – 100%; Fixed (Hz): 1 – 500 Hz Frequency Resolution: as fine as 0.000001 Hz Control Mode: either open-loop or with close-loop control Notching and Limiting Limiting is applied to control or monitor channels. Three types of limiting are available in Sine Control: frequency domain, time domain, and advanced limit. Two types of limiting are available in Multi-sine control: frequency domain and time domain.
