Caught on video - the rotating scope screen

Back in February when I first wrote about LeCroy's WaveRunner 6 Zi, as well as its up to 40 GS/s sample rate, the thing that really caught my imagination was the pivoting display that permits viewing signals vertically as well as horizontally to obtain more detail for optimum analysis.
The pictures provided showed the screen in horizontal and vertical positions but really did not do the novel design justice.
I took the opportunity while at Embedded World in Nuremberg to persuade Raffaella Ricci, the Distribution Sales Manager in EMA for LeCroy, to show me the display in action and I managed to catch it all on video.
The 12.1 inch high resolution WXGA wide screen is designed to provide the best view of any signal type on the display. The widescreen is suitable for a variety of signals where long records are required and zooming or scrolling. Rotating the screen 90 degrees optimizes the display for viewing digital signals, jitter tracks, eye diagrams, and frequency plots.

Impressive! that could actually be useful.

One summer I used LM3914 chips to create a cheap LED oscilloscope. The vertical axis was 10 diodes high and the horizontal was 20 diodes.
In order to obtain better resolution on the voltage, I had switches to allow swapping the X/Y channels. Worked great.

When I have a lot of channels to view, I'd rather add an external monitor. Then I can get whatever size/orientation/resolution I need for the task at hand, without worrying about the added expense and reliability risks of a special-purpose pivoting display.
It's still a cool idea, just not one I'd actually pay for.
