==Operation==
In the 7A14, the ring around the input [[BNC connector]] that is used to identify ×10/×100 probes on voltage probes serves the purpose of detecting the difference between the P6021 and P6022 probes, and switching in appropriate gain and frequency compensation.

The P6021 shorts this ring to ground, directly switching three relays connected to −15 V internally. When connecting a [[P6019]] probe, the ring must also be grounded but the probe connector does not have the matching pin.  The [[131-0750-00]] adapter solves this problem.

The front panel gain control screwdriver adjustment affects gain for either P6021 or P6022, i.e. swapping probes requires re-adjustment.
