Generally, a scope probe is best represented as a very small capacitance to ground, followed with a rather large resistance. That capacitance tends to shut most high frequencies to ground. Of course, as things are with the black arts of RF engineering, there are possible situations where that same probe would make things worse, or appear inductive.
