Yes, but my point was that the entire MHz Hz part of the MHz symbol is a single custom character in a custom font, purpose-made and baked into the silicon, just so they could fit it all in the space of one character; and that they did this so it could be generated fast enough to render legibly in the space between sweeps on a 400MHz scope. In the age of the VIC-20 and Commodore-64.
Now THAT is some fucking hardcore engineering, and it was on something so mundane, we don't even give it a second thought... things like THAT are what set Tek apart.

I had this discussion the other day...
Why do you use this old stuff when you can buy a brand x fill-in-the-blank that does all that, is firmware upgradable, weighs a tenth as much, and has a color screen and wifi, to boot? Because...
- dollar for dollar, it generally works better, especially at the limits,
- it is often more reliable in the oops-i-shouldn't-have-done-that sense,
- it is thoroughly documented with schematics, BOMs, test procedures, and almost always, theory of operation information,
- it is repairable by design,
- it is more carefully manufactured,
- it was designed by people that used what they built, every single day.
I am glad I own a Siglent SA that, for 1300USD, doesn't take a lot of square inches of bench, and works well enough for ninety-five percent of what I do. But it is, for the most part, an unfathomable, unrepairable, unmodifiable (except by accident) black box. More importantly, it is not a joy to operate because Siglent's objectives are quite different from those of the people that designed and built my big, heavy, beautiful 475 and it shows in every way.
At this point, the eyes of my young interlocutor glazed over, and I stopped ranting.
And, yes, I need coffee.
