Why Sigma Clipping?
This feature prevents amplifiers from tripping when the input ranges of an amplifier are lesser than the drive signal required to achieve a target GRMS.
Seminar attendees learned everything from the basics of setting up a modal test to best practices in testing and in-depth modal theory. Modal testing variations included hammer excitation, SIMO shaker excitation, and MIMO shaker excitation.

DSA is often referred to Dynamic Signal Analysis or Dynamic Signal Analyzer depending on the context. DSA uses various technologies for digital signal processing. Among them, the most fundamental and popular technology is based on the so-called Fast Fourier Transform (FFT). The FFT transforms the time domain signals into the frequency domain. To perform FFT-based measurements, it is important to understand the fundamental issues and computations involved.

Sure…sometimes it helps to stand back and look at everything from a complete picture. I have a figure that I have used for many years now to help people see things more clearly. I call it "The Big Picture". Let's just look at this picture and discuss all the pieces individually.

Crystal Instruments Multi-Exciter Single- Axis (MESA) vibration test control allows users to closely replicate real-world applications according to the complex and multi-DOF nature of real vibrations. MESA vibration testing is most commonly used with higher forces on each axis and with long vertical dimensional testing units. Crystal Instruments provides the highest quality and technologically advanced solutions for MESA vibration testing and recently provided comprehensive MESA testing on a dual 300 KN shaker system at an industrial environmental testing lab.

There must be more to this problem than what was stated by your question. My guess is that you are performing a modal test on a structure but you are not measuring all the significant modally active portions of the system during the modal test.
