WebApr 25, 2024 · In Sine or Random control, notching and limiting is a common technique used to limit the response level within a certain frequency range. Previously, users were not able to limit the SRS spectrum level within a certain frequency range for any response channel. Predictive Notching provides a limiting function for any input channel. WebThe Random Vibration Testing System provides precise, real-time, multi-channel control & analysis. Random vibration testing supports up to 512 input channels. Users can enable up to 128 channels for control and notching. Users can designate the rest of the channels as monitoring and time data recording channels.
