The '''Tektronix 465M''' is a 100 MHz dual-channel portable scope, a ruggedized version of the [[465]].  A large user of the 465Ms was the Federal Aviation Administration.

Whether or not the 465M was more rugged than the original 465 is unknown.   
Whether or not the 465M was more reliable than the original 465 is unknown.   
In the Oklahoma City Tektronix Service Center,
a lot of 465Ms came in for warranty service,
primarily from the Federal Aviation Administration
which had purchased a large quantity of that model. 
But the rate at which instruments are brought to a service center
is not by itself a measure of reliability, as one would be comparing
the failure rate of a large number of new 465Ms
that were shipped to the customer's depot
with an established base of 465s which already had
most early defects corrected.
