 It connects to the scope with a [[UHF connector]].
-The P410 was [[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.  The P410 uses a special cable with a very thin, high-resistance center conductor which creates a better impedance match.  All high-impedance probes subsequent to this use this kind of cable.
+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).
