The Tektronix 2465 is a four-channel 300 MHz portable oscilloscope. The 2465A is a 350 MHz scope and the 2465B is the 400 MHz version.
It is the same as the 2467, except that the 2465 uses a conventional CRT while the 2467 uses a micro-channel plate CRT.
The 2465 scopes are the penultimate generation of analog scopes from Tektronix.
