If you just want to see the square PWM wave just connect the scope to the output terminals on the Victor. I think you'll get the same results whether or not the motor is connected. If you want to see the sawtooth wave generated by the rising and falling current in the motor you'll need to connect a current shunt in series with the motor and connect the scope to that.
