New 2GHz touchscreen scope from Tek, June 6th

Frenky posted this back on page 2:





Looks very similar to the existing VPI interface, but note the extra slots on the bottom either side. New probes with those protrusions wouldn't plug into existing VPI scopes. Or at least the analog ones wouldn't. Maybe they have a new digital version of the VPI?

The knobs. Oh, the knobs.

LOL but that screen is a damn sight too small for that many traces!

But some people do insist on having a separate vertical knob for each channel....

How big would a scope need to be to do that and have the requisite screen real estate?

So it looks like Tek has gone the route of color coded LED lighted knobs and buttons just like the new R&S scopes.  Were R&S the first to do that or has it been done by someone else?

Lecroy... decades ago. Edit: DDA-260 for example

I guess it fits into a standard 30 inch rack, lol.

Thanks, that's interesting.  I guess now that the idea can be combined with a touch screen, it adds a whole new dimension. I understand where the concern about not having a separate vertical control for each channel comes from. I had the same concern. But at least for me I've found with my RTB 2004 the combo of color coded LEDs and touch screen to work just fine.

If the trend is bigger screens and more channels, I don't see a better option.

With shared vertical controls it is much easier to also use the vertical controls to control math, decode and reference channels. On scopes with dedicated controls per channel controlling the math and reference channels is often much harder than it should be.

Bah -- that argument just proves that you need more dedicated knobs, for the math and reference channels too!

don't know why this reminds me of a V8.

IMHO there will be too many knobs at some point. Math + reference channels can easely add up to 6 extra traces. Using the same knob to control the vertical position of traces has it's advantages.

Sure; I was not serious. Hence the  "".

If it's a touch screen you just drag the channels around, no vertical knobs needed.

Na, more like a "Straight Eight"

Not if the trace is off the screen!
And you still need a "vertical knob" for vertical resolution control. Controlling that with pinch gestures is very imprecise.

That can be made into a button on the screen as well. You should really try MicSig's tablet scopes to experience you can do without knobs on a scope which has a touch screen.

That's a good point, although I'm not convinced you can make a touch interface that gives the same amount of precise control for vertical resolution. You need some tactile feedback for that.  For example, using the built in web interface on the RTB2004, I find the "virtual knob" for vertical resolution control pretty imprecise.

You're just not imagining.

If it's off screen you can have a marker arrow at top/bottom to show where it is. Touch the arrow to grab the trace and bring it back on screen.

Says who? If it's done well and snaps to the usual voltage ranges then it'll work perfectly.

Want fine control? Double-tap it to bring up a numeric keypad and circular control knob.

Says me.    It's just an opinion of course (shared by others though) YMMV.

Well yeah - a numeric keypad is always an option.  A very slow one.

If you're gonna argue that there's no advantage at all to at least a few physical knobs then you are veering into USB scope territory.  Paging Mr. Wolf....

Yes - I really like the way the RTB has made all vertical trace functions work consistently - moving digital channels around on the Keysight can be a real fiddle.

Only 1 day to go to judgement day. TKO for Tek ?

I want this scope.

Buy two of these and put them side by side.  As a bonus, you get two timebases and DSO capability.
