Why are scope probes so damn big?

alanambrose:
Duh, we're working on these little things 1mm scale, and the damn probe is over 6 inches long with all the leverage that goes with that. Is this a design left over from the valve radio era that hasn't been updated?

It's probably for human ergonomics. Anytime I'm working with really tiny stuff, I change out the tip to get the ground loop very small and close to what I'm measuring. Or build something custom.

ataradov:
Do you have a better design in mind? Propose one. They are inconvenient because nobody came up with a more convenient idea.

You need something to hold comfortably and the size and shape of a pen seems to be right.

ataradov:
This is not a design. How would you hold this? The leverage is now in the cable. How does this help?

Probes are already about the size of a pen. Tektronix has smaller than usual probes, so you may want to look into that.
