Change text in one panel and measure time for text appear in preview in another panel

I have page with 2 panel if I type something in 1 panel the the other panel generates a preview.
eg if I type a word in one panel thenin the other panle the word appears in a preview, I want to able to measure the time it takes to appear in the preview and the test to fail if it takes longer then xxseconds to appear.

Is there way of doing this in Testproject, I tried you using conatins text (if visible) with adaptive wait but this does not work for me?..

Appreciate any help?

This can be ignored the real issue is that I want to verify text in PDF panel.
