Actually, you don't want to do this.  You need a differential probe to do
this properly, or just leave the ground lead of the probe hanging when you
do this otherwise you will kill your FETs due to the short circuit between
the ground lead of the probe and the circuit.

The same goes for the output of the full / half bridge circuit.  Need a
differential probe.
