Calculating the RMS of a Random Profile
There are two common ways to interpret the frequencies between each breakpoint in the Random profile. The most common method is Log-Log (meaning the log of the amplitudes scales with the log of the frequencies.) Another method is Log-Linear, where the log of the amplitudes scales directly with the frequencies).
In this post, we will show how to calculate the acceleration, velocity and displacement RMS values of a Log-Log and Log-Linear Random profile.

Multi-Resolution Spectrum Analysis and Sine-on-Random Testing
In this blog post, we will discuss the benefits of using Multi-Resolution, a feature available in Vibration Control Systems, to offer a better frequency resolution in the lower frequencies of the Sine-on-Random vibration spectrum. The same benefits are also applied to the general Random test, and Random-on-Random mixed mode test.
