I just had a live demo of the new R&S RTE oscilloscope. I'll post a link here when it's posted.

I also am one of those old fuddy duddys who like KNOBS on my scope.  Sorry.  Touch screen control are very imprecise.  The click of a knob that is always in the same location, with a minimum of menues is my kind of scope.

Sorry, but my first oscilloscope was (still have it, worked last time plugged in) a Heathkit 104.  THOSE analog oscilloscopes the knobs could be used for fine adjust.  Digital oscilloscopes, unless told otherwise ("vernier mode"), generally step in increments when one adjusts parameters.  Typically these increments are 1,2,5,10,etc.  Also, I normally like my zero point at some "rounded" vertical location (at least on a minor, dot, location on the vertical axis, with preference for major, line, locations).  As such, and as a long-tme digital scope user (early '90s), I am VERY ready for a touch screen tablet/phone type interface on a digital oscilloscope.  The problem with most digital scopes is that there are a lot of knobs for a 4-channel scope with cursors, trigger, and horizontal controls.  Alternately, one spends an inordinate amount of time going through button menus and submenus to share the controls provided.  I quit counting how many times I have been frustrated by changing from the Agilent to the Tektronix to the Fluke, etc. interface and operated the WRONG controls reflexively.  One BIG request to all of your oscilloscope interface designers out there:  Please get together and make at least most of your human-machine-interface consistent.

@JRAS, touch screen controls are only imprecise until you get used to them. The change in the usual 1/2/5 increments, just like a knob.

What do you base your conclusion on here?

MeasurementBlues,

USB is too many layers, too much of which is unknown to the user. Too many brands do not comply to the agreements, often it is implemented very badly and last but not least: My own experience.

Do yourself a favour and try the following. Get an USB analyzer. Get 2 computers and a bunch of USB devices. 1 computer is a Windoze PC and the other Linux or MAC. Now try out the different devices, and show the screen what it all does. it is HORRIFIC. What a piece of crap most devices are. Even HIT-devices are not always implemented properly, what a shame. Even a hobbyist does it better. Trying things out on linux or MAC show you a ilttle less traffic, but even then I would not dare to use it long-term stand-alone.

@Navelpluis, is it the computers or the devices or both? What kind of devices are you talking about? Do you find these issues with test equipment or just with consumer-grade products?

@bcd_testech, get used to touch screens. Knobs will be gone in 10 years. Knobs are are fuddie duddies. they're not cool and the next generation will only do what is cool.

And then get ready to change again, because in 10 years, touchscreens won't be cool.  for exmaple, gesture sensor is already here.  Why deal with touch when you can wave?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
