Well it depends on what you mean by scopemeter ...

Do you mean a scope match
<http://ve7sl.blogspot.co.uk/2014/08/your-lf-stations-best-friend-scopematch_5.html>
?

or one of those 'fluke' handheld scopes
<http://www.fluke.com/fluke/uken/products/scopemeters>?

If the former it depends on the coupling ratios you have chosen, mine is
set to 1V/A & 50V/V so same height traces = 50R
