System Noise and Ground Loops

February 12, 2020

A vibration testing system is connected by various cables that transmit electrical signals, which contain noise. Vibration controllers are very sensitive to electrical noise and it is often visible during testing.

There are two sources of noise in vibration testing systems: ground loop noise and electromagnetic interference (EMI). Both sources can cause a variety of problems, such as measurement errors.

In this course, you will learn

  • What causes system noise and ground loops
  • Indicators of ground loop noise in a vibration testing system
  • How to troubleshoot the most common reasons for system noise in a vibration testing system
