Measuring INtime RTOS jitter performance

Jitter is the deviation from the true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter.

INtime Jitter Test

We recommend no more than a 40uS offset/deviation from the "Average Tick" value. Having a deviation greater than 40uS might cause our controller to miss a cycle and behave unexpectedly.


  1. Navigate to: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\INtime

  2. Open the application: Platform Assessment Tool

3. Select NodeA and click Start. Jitter Test will begin.

5. Observe the offset/deviation from the "Average Tick" value and compare with recommended offset/deviation.
