Hi,
I'm enjoying my new oscilloscope at the moment but couldn't help noticing that the graticule isn't square. It is approximately 15 x 12 mm.
Coming from a Tektronix 7104, I'm used to a perfectly square-shaped graticule.
What is the reason that the Agilent scope is not square?

If so...
Old scopes were based on electrons being fired from a "gun" in the back of the CRT, and being deflected, magnetically, as they moved toward the front. It was easiest to make those vacuum tubes the same dimension in the vertical and horizontal direction, since the same magnetics could be used in each direction, among other things.
Modern scopes are built with LCD screens, and almost all of the ones available are either in a 4:3 or 16:9 format, that's what the scopes have. All measurements are made by the scope and the vertical and horizontal settings are in terms of divisions. Some scopes use space on the right side for measurements, which helps square things up somewhat, but since text tends to go horizontally, the top and bottom of the screen get used, too.
It's a new world.
