Connecting the PL-50pro to the input BNC of the oscilloscope will give you the best effective to reduce the overshoot and ringing of the input square wave.
PL-50pro uses gold plate to prevent oxidization and also using beryllium copper on the BNC to lower the contact resistance and increase the durability and contact life.
