Tektronix tweaked the probes meant for the 2465B to match
the response of the inputs on the 2465B, so for specified
performance, only a p6137 will do.
But, likely you will never notice the difference.
The 10M, probe tip, frequency response of these scopes was
simply bragging rights for tektronix.
The parallel capacitive reactance at the probe tip swamps
the probe's 10M resistance long before you get to 400MHz.
It even swamps most circuits where you might think you would
like to make a measurement using a 10M probe...
Amuse your date, calculate Xc for the probe at 400MHz.
P6135,6,7 probes are pretty easily damaged. Often it is
better to get a much slower P6105,6,7 100MHz probe, and
enjoy its near indestructibility.
It is unlikely you will ever be bothered by its frequency
response.

A quick question for the group. I have a 2465b and have found a p6139a locally in good condition. Is this probe a good match for my scope?
