Transient and CTT are most critical CAL, but PS,Hor and Vert are easily

I really should look at doing the transient calibration on my 2467 now as
my GAS (Gear Acquisition Syndrome) has left me in possession of both a
home-made tunnel diode generator and e.g. an S52.
You can CAL without the Tek CAL, but it is long and doubtful of complete
success.
I think first-time calibration from the instructions in the manual is
always going to be a long and doubtful process :). I know I had to run
through the process at least twice, and I probably repressed a couple of
run-throughs. I remember the B time base requires a second scope, and it
wasn't until years later and I'd scoured the schematics that I understood
the purpose of the step (for 15 minutes, don't ask me now).
I think for many here the journey is the reward, and at least OP is certain
to learn some things.
I should also note that the calibrator in the 2465-series is intended to
allow checking most of the time base calibration with nothing but the scope
and a 10X probe, that's why its output frequency follows the time base (to
a point).
The output of the calibrator is also specified to be 0.4V peak-to-peak to
sufficient accuracy to allow checking at least a couple of vertical ranges.
