EMC-mask

Postby driesdendas » Thu Aug 31, 2017 7:49 am

Hi,

For reporting i need to add a EMC-mask (max values allowed) as in the picture in the attachement (red is mask, blue signal)
I found an image on https://www.picotech.com/library/oscilloscopes/mask-limit-testing what seems to be the same but inverted, but however i don't find a way (yet) to make this mask.
Can someone help me out?

Kind regards
Dries

The red trace in your picture is the solid blue block in our spectrum mask image, the actual mask, so actually both are orientated the same way.

If you watch the video it will help to explain how to create a mask from a known good captured plot, in simple terms capture the plot, then select the mask menu and generate the mask automatically.

Solved: I imported the FFT-values in excell and personally for me it was a lot easier to make the graph.
