Matt,

You do not need two probes to do this,  just stick a piece of wire in the
BNC jack center terminal and the outside terminal.  The outside can be
considered the "ground clip" and the inner terminal is the "scope probe"
Use that to phase your transformer(s) and if you're just using a half bridge
you really don't even have to use a scope.
