Marker Peak Finder Position Inaccurate?

Hi

Could you please tell me that why this marker cant find signal peak correctly ?

in your video marker working very good
but in my test , its not accurate?

The marker position accuracy depends on the FFT size. The higher the FFT the better the accuracy.

If you play with the trace interpolation methode you can see what is laying behinde the trace:

"Nearest" shows the single bins. This is the measurement reality and the real resolution and used for the marker position.

All other trace interpolations for sure look better but are not real and might lead to wrong looking marker positions in high zoom rates.

Attached screenshot uses a very high zoom rate to better show those details:

Thank you so much for your very detailed answer !
it was very beautiful. Actually i learning your software.

Do you have any detail help for this software?. ( in online help there is no any detail information )

Thanks again

Also note that the marker is assigned to the "Clear/Write" trace, not the "Maximum" or "Average" trace.
