To anyone complaining about the membrane keypad: you are not going to use it. It is stupid to put knobs & buttons on a touchscreen based instrument which has a proper touchscreen interface. The knobs & buttons are redundant relics from a past.
And yet, silicone keypads do get dirty. If you have ever cleaned a piece of test equipment thouroughly you know how much dirt you encounter on such keypads. Usually enough to make a 10x10cm piece of white cloth turn dark grey.
Then why not ditch the rotary encoders too ? simply pinch to zoom.
There needs to be a few hard buttons. run/stop , single , since they only have one encoder for vertical you need buttons for channel select. The amount of arm flapping needed to first touch something on the screen , then go to the encoder, then back to screen ... if that thing is suspended from the vesa mount you will get muscle cramps very quickly.
I don't know if a touchscreen on a scope is a good idea. Touchscreens work on a tablet because it lays horizontally. Vertical touchscreens are very tiring for your arm. And you have greasy finger streaks all over that display. -meh- Scopes sit on a bench at arms length. very difficult to precision control a floating touch screen at arms length. I can see this working for field service personnel holding it in hand. but as a bench instrument ? no.
i had a Lecroy and an Agilent with touch screens. i HATED those touch screens (except for zoom in/out). always used the mouse or the hard controls. but changing gain or timebase ? annoying as hell. and then trying to enter something on a virtual keyboard is even more annoying. it works if a touchscreen lays down, like a tablet, or if you are handholding it . but not on a vertical screen.
They seem to have the button balance right. only the really important stuff has a button. They should at least provide haptic feedback so you know you clicked something. having to stare at the screen to see if it changes when you click is annoying. find button with eyes, position hand, move eyes to screen , now click , . bad UI design. a proper UI minimizes the number of eye repositions and hand repositions.
