How about an Anti-Gravity-Oscilloscope  :D

The next stage is quite obvious: Relativistic effects compensated oscilloscope - you choose your frame of reference, enter your speed, the speed of the measured system, any additional gravitational fields in place and you're in!

This might explain why the traces on my DS1054Z are a bit above the center line. I am at 2500m altitude and the gravity is a bit less here. Oh well, time to hurt my wallet again.

I think this video might have been published a little too early for us west of Greenwich!

So you obviously had some "Teknical" help. It's nice to see a company with a sense of humor.

I bet they get the extra memory bandwidth by using a bunch of these babies!

It was about time, this scope is exactly what I need.

I needed better accuracy for some old project and no existing oscilloscope had gravity compensated oscillator. Compensating for the other stuff is relatively easy temperature, humidity, time of the day and such, but compensating for gravity it is more difficult.

I’ve found a DIY solution to achieve gravity compensation. Basically we fixed the oscilloscope in a device which allowed it to spin on one axis. After some experiments we’ve found that about 3000 rpm gave the best gravity compensation. It was difficult to get the power supply and signals to the spinning oscilloscope but it was doable. Reading the display was solved by using the simplest solution available, we just used a 3D TV active glasses and synchronized to the spinning frequency of the oscilloscope so it let light through only when the oscilloscope’s display was in the right position.

This improved much the oscilloscope’s accuracy but still was not quite enough for our project. So new ideas were developed, e.g. spinning the oscilloscope on all 3 axes should improve the measurements by at least an order a magnitude, but now we don’t need all that, thanks to Tektronix.

Does anyone know when this will be available, I would need it soon.

Finally the T&M industry is catching up. High end watches have had gravity compensated oscillators since around 1800.

I wonder when they will introduced a cloud based solution. No more reference oscillator in your device, it could all be pulled from the internet.

I have had some success experimenting with connecting several crystal to a PIC (16F628) to improve accuracy by averaging out the ppm errors of the individual crystals.

After watching this eevBLAB I had a brainwave and have decided to connect a total of 6 crystals.  A pair in each x-y-z plane but in opposite orientation in an attempt to totally eliminate the effects of gravity.  Again the initial results look quite promising.  A side effect is that the PIC does not always startup properly after a power reset. 

As with calibration, it takes quite some time to allow the experiments time to settle and ensure long term stability and the effects of gravity are actually cancelled.  Also need to ensure the results are repeatable and fix the startup issues.  I am hopeful experimenting with the crystal bypass caps may help.

I would not be surprised that Tektronix may have some interest in public/private space exploration, aircraft, etc. - offering scope compensated to gravity effects is a smart move.

You also need to take relativistic effects into account for space travel (or even on the ISS), not just gravity.

Hi Dave. I like your video about the great new Oscilloscope.
It's time someone constructed one to compensate gravity.
Well, I'm an obstetrician and I constructed one,
which compensates for gravidity also and makes a good coffee!

I wonder how the engineers in Tektronix compensate for these other variations, some of which cause 10x as much effect as gravity?

i am wondering too. They are using a TCXO with a better stability than any OCXO i know. Even aging is better - how did they do that (well okay - aging is mostly linear, maybe it's software-compensated)?

Actually I put a lot of high density bricks around my oscilloscope it really helps to attenuate and dampen the gravity aberrations where I live.  I have been doing this for years now and I am very happy with the results.  I am still working on compensating for the tidal variations from the sun and moon.

So...
Was that an April 1st video, or is it a real product?
I'm in Chile now, which is also upside down, but the date is N+1(+-50%), so i can't quite figure out if there was April 1st anywhere back then or not.
Tektronix page does look fishy...

Its a winner.

I'll buy one if is equipped with the unique Tektronix patented
Write Only Memory (WOM) and the gold plated bi-stable switch glands.

I looked in the option list but I cannot find the 3 phase 400V AC version!
Why spend money I don't have on things I don't need to impress people I don't like?
