Software can cost a lot more than the hardware design does.
The DZ1054Z software is ok. It’s a compromise. After a few weeks it is committed to muscle memory so it’s not an issue.
And the memory between the ears.
The UI is just that and all are different whether it's a DSO or CRO.
Most that have spent years using the same scope initially have difficulty coming to grips with a new UI.
After using only a D83 for a few years I got an HP1740 and thought HTF do you drive this thing ?
With the increased functionality of the modern scope, things have to be buried in menus and how they are laid out or similar functions are grouped is the key to getting to grips with things quickly.
It doesn't take long to get used to a certain layout/structure IF you're a competent scope user that knows how to go about obtaining the result you need.
As for coupling on the DS1054Z, press the channel then the coupling button a couple of times. You don’t need to use the encoder. The menu is informational only.
Yep, that's how the Siglents work too....toggle to the next menu item.
The only thing that I consider annoying is that the channel select and enable/disable is on the same keys so periodically if I’ve forgotten which channel is selected (which is half way across the scope on the screen) I’ll end up turning it off rather than select it.
Is there no visual indication which channel is the controls 'active' channel ?
I thought the Z had a lit button showing which was the active channel.
