I would say it's pretty much a full on functional test.  Then again, I am sure we all have some horror stories when it comes to calibration houses.

For a meter it is pretty typical to have at least one test recorded against every range. But more complex instruments such as scopes only have some of their parameters verified (and/or listed as warranted in the specifications), say channel to channel crosstalk for instance being unwarranted and untested. Or bandwidth, warranted, but untested in different voltage ranges.

For the bandwidth you mentioned,  the factory tests all four channels at nine different voltage levels, not one.  Mine is an 8500A

Different scopes, different manufacturers, have different calibration record/limits/requirements. Not surprising at all.

A sticker on a product that says CALIBRATED (even if in date) is the start of assurance, not the end. Taking a blanket approach can leave the end users complacent to the details of what is inferred by "calibration" and what is actually explicit.

This is one reason why I request reports.  Sure they add to the cost but I can easily tell what tests were performed, what equipment was used to perform those test, when the equipment was calibrated.  Of course, how my equipment performed during each test.   

Like any other job you may contract out, it's not a commodity.  It's good to interview the company you plan to use and make sure they can provide the service you require.

I would say it is understandable he is just upset he cannot keep up with a fella who lives in Australia that spends a good bit of time outdoors where everything tries to kill you.

The insects try to kill you, the birds try to kill you, the wombats, the dingoes, the drop bears and the endless snakes all try to kill you.  Even the trees and plants try to kill you.  Think the water is safe.  Nope, even it tries to kill you.

These companies sending stuff in for reviews, know to send it to a country where everything tries to kill you.

It is a miracle that Dave managed to survive into such a really old age there. I bet he is already above 30.
Probably because he has that big knife which he can use to kill things day and night.
If he would do a video about his way into the office, it would get a 18 years rating. (Because of violence of course.)He is a hero.

schmitt trigger:
Of course! His vehicle’s Roo Bumper has powerful lasers to blind the kangaroos before running them over.
