The Tektronix P170CF is a cathode-follower probe intended for use with the 517 scope, or a Type 128 power supply. It came with three attenuator heads.

The P170CF uses a 5718 triode. It requires a 170 Ω termination which is built into the 517 and needs to be externally connected for other instruments (the B170-R terminator with UHF connectors was available for this).
