content: Another explanation is that if you're going to develop a similar product it has a high chance of looking similar.And I don't think that the interface is a copy at all.And both contain elements that have been used in many products. (4 direction keys, numerical keys, multifunction keys around the secreen)

content: I don't get it. They both look like 3 channel power supplies. They all look this way.Keysight one looks nice.

SMUs and DMMs are not much different in the way they look.But across manufacturers, Keysight, Fluke and Keithley all have distinctly different look imo. Personally I like the Keithley meters the best, but Fluke 8846(5)A is the sexiest looking one of the bunch (the new Keithley DMM7510 looks pretty slick as well), HP 3458A for instance is ugly imo, but a great instrument.

content: Not too different from say a N6705B from Agilent time. Large pixel displays have driven this kind of UI, mercifully you can't generally patent or copyright that.

content: That layout of display, buttons, power button and I/O is pretty typical of all T&M equipment, not just power supplies

content: I don't know about you guys but when I first saw this keysight PSU immediately I thought about the DP832. The GUI looks complete copy ...

content: Maybe there is similarity in general shapes (and depends on the observer, e.g. which features you're naturally focusing on - for some it may look more or less similar than others),but having no experience with bench PSUs, I noticed the button layout was different, and the information presented on the display is different (e.g. keysight is multi-colored in some kind of graphical columns for channels).Other details are only seen (by me) after nothing first those large differences (button layout, display info) and by looking more carefully. Such as, Keysight has an uncovered USB jack in front, while I can't see it on the Rigol one (perhaps it's on a side or on the top, or covered for protection, or not featured in that model).On a slightly unrelated note, they both look amazing and expensive, lab-grade stuff (I don't know if they are, but that's how they appear). As someone who hasnot useda real bench supply yet (even the Chinese ones), I find Keysight button layout slightly more straightforward, with a knob for "Voltage" and "Current". Okay, Rigol has adigital(I meant button vs encoder) solution of the same thing with arrows marked for mV/V and mA/A, but still it took slightly more time to read that than find the knobs on the Keysight one. Of course, none of that matters, because the basic functions are surely grasped within a few minutes by anyone on most PSU's, and after that first time, you don't really care about how very slightly easier or more difficult is to see and get a hang of at first as you already know the layout.
