It is like this:
Calibration solves multiple issues.
Done to its logical conclusion, it makes all of the measurements
made by your scope consistent (to within the scope's uncertainties)
with every other lab in the world.
Less rigorously done, it can make it consistent with all of the
test equipment in your lab... assuming that you use that test
equipment to calibrate the calibration equipment that calibrates
your scope.
You need only the loosest connection to NIST and the world to make
your scope perform with fidelity, in as far as transient response,
trigger response, CRT behavior, focus/hidrive focus, rotation,
linearity of display, jitter of readouts, DAC calibration, .. power
supply ripple, and voltages, and many other things I forget at the
moment.
If you want to know what it costs to get it done, not traceable
to NIST, but better than tek's specifications, contact me off
group.
It is way less than the cost of buying all of the necessary
equipment.

Interesting. But not entirely surprising given that components will age and wear in.
On a related note... what would one expect to pay to have a 2400 series calibrated by a service? Or is it cheaper to just acquire the relevant gear and do it oneself?
