The 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. The recording option records time stream data at a full sample rate on all input channels. A unique hardware design provides a fast loop time of less than 15 ms. An optional Kurtosis control can create a non-Gaussian random signal. Annual updates are available through a convenient software subscription. Unique Advantages Displacement Optimization for Random: A proprietary algorithm was developed to minimize displacement during Random Vibration Control testing. Displacement is reduced by 10% to 20% while the target PSD profile can still be reached. (Patent pending.) Multi-resolution Function for Random Vibration Testing: EDM provides the multi-resolution feature that applies the selected resolution in the high-frequency range and 8 times of the resolution in the low-frequency range. The cutoff frequency, which divides the low and high-frequency range, is calculated by the software. (Patent pending.) Control Dynamic Range in Random: One of the key requirements for a random controller is to achieve high control dynamic range. Control dynamic range is a measure to compare the highest and lowest spectrum amplitude in the control signal. Spider vibration controllers can achieve at least 90 dB control dynamic range.
