Jitter
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.
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:\Program Files (x86)\INtime\bin
- 2.Open the application: jitter.exe
jitter.exe
3. Select NodeA and click Start.
4. Click on the "+10" button.
5. Observe the offset/deviation from the "Average Tick" value and compare with recommended offset/deviation.
This is bad jitter.
