Rigol 1054Z Saving Memory to USB

[engrguy42]

Why does it take so long to save a memory snapshot to USB?? It's only like a 62Meg file. It takes forever. Even if I shout at it and hit it with a stick it doesn't go faster.

It's like 15-20 minutes or something.

Arrrgghhh...

I think it's USB 1.0, that's why it's so slow, I don't think it's 2.0

Oh yeah, you're probably right. That's back when we had 28k modems and stuff.

Sometimes it goes fast. I think it might depend on the format of the stick or something. Or it might be something else. It can definitely go fast though.

Perhaps it is the preparation or converting before writing that takes this time, less writing ?

Screenshots are written by my DS1104Z e.g. as a png strangely much faster (usually more than twice as fast)
on the stick than jpg, although png are at most 20% smaller on average than jpg.
It is probably less because of the speed of writing, rather that he needs less computing power for png than for jpg
