I'm looking for two types of "scope plugs," or adaptors where you insert the pointy end of a probe so it is held in place allowing "hands free" measurements. The first is an adapter insert for a BNC connector: you insert the adapter into the BNC which can accept and hold the scope tip. I've only seen these accompanying new probes. The next kind accomplished the same as the first by replacing the BNC and adapter with a connector made to accept the probe tip. A shout out with names, part numbers, and or sources is appreciated.
