The Tektronix P6032 is an 850 MHz cathode-follower probe, intended for use with samplers such as the 4S1, 3S76, and 1S1.

There is an EC1000 subminiature triode in the probe body, which is why it gets slightly warm during operation.

Like all active probes, the P6032 requires power, and for this reason it has two connectors at the scope end of cable. There is a four-pin power connector and a 50 Ω GR-874 connector for the signal.

The triode has limited dynamic range, so attenuator attachments are provided that attach to the tip of the probe. These attenuators also reduce the loading of the probe on the probed circuit.

What, exactly, does the clipping line in the probe body do? It appears to be 21 mm of RG-174 cable connected to the triode's cathode at one end, and open at the other end. The circuit description in the manual describes it vaguely, saying only that, "The clipping line reduces signal aberration to a minimum."
