A NEW FEATURE FOR ON-LINE USE
We have now linked those measurement points , which are related to the
oscillograms shown on the signal overview page. As example: clicking on the
measurement point guides you to the matching oscillogram on the signal overview
page. The next click onto the now shown signal guides you to the related measurem-
nt point on the module. Finally, a third click , now onto the measurement point on
the module, takes you back to the starting point inside the schematics.
Do you have further improvement ideas or would like to give us feedback?
