The '''Tektronix P410''' is a 10× passive voltage probe. Maximum voltage is 600 V peak-to-peak.  
It connects to the scope with a [[UHF connector]].

The "P400 series" (not to be confused with the modern [[P400]] probe) also includes P405 (5x), P420 (20x), P450 (50x), P450-L (50x extra low capacitance), and P4100 (100x).

These probes were [[Introduced in 1955]] along with the [[541|Type 541]] and [[545|Type 545]] scopes because at 30MHz the [[P510|P510A]]'s 50-ohm coax cable exhibited unacceptable ringing due to the impedance mismatch at the scope's 1 MΩ input.  It uses a special cable with a very thin, high-resistance center conductor which creates a better impedance match.  All subsequent high-impedance probes use this kind of cable.

All subsequent high-impedance probes use this kind of cable.
