Oscilloscope Music on DSOs- Post your Results

[Martin72]

Hmm....Good question, will test it.

[Martin72]

Hi,

ERES is possible in XY mode, the difference is clearly visible.
Will upload a short clip (in progress).

(first 30sec: Normal, next 30sec: Eres 3.0, same scenario)

Do the siglents have good Z modulation too ?
My Agilent has only blanking, not variable intensity.

It's important for scopetrex/vectrex use

Member TopQuark mentions he uses a colored grading setting that will assist in showing intensity.

Siglent XY is normally just a blue trace but if you study some of his examples you can see subtle trace color changes.

AFAIK there's no Z-axis functionality at all, blanking or variable.

[Martin72]

Yep.
The first time I saw anything about a Z-axis was in the XY menu of the Rigol DHO800....

Ah, that must have been where I saw it too. (In the DHO1074, to be precise.)

I got my Asteroids arcade board out yesterday and connected it to the SDS800X HD, to see whether I finally have a DSO which does a credible job displaying that vector game. Only to find that the scope does not support a Z input (for beam intensity modulation) at all. Bummer...

I'm afraid the excitement about CROs finally having become totally redundant is premature.

I had purchased the Rigol (DHO1074), and while it supported Z control, its XY performance was less than convincing. More importantly, there were other things I disliked, as discussed in the DHO1000 thread in January -- enough of them to make me return the scope, sacrificing the great Black Friday price I got.

Rigol DHO800:

That's unstable and choppy. You should see if you can get better performance with lower memory depth, or see if turning off the waveform box improves it at all.

[joeqsmith]

Better than the show us your square wave thread.  IMO, this music thread is a lot more informative. 

Rigol DHO800:

That Rigol looks like what my old scopes would show.

I might give it another go.

That video was recorded over the web interface which might not help either.

I assume it's similar for your Rigol, but the web interface on my Siglent has a limited frame rate. I'm guessing 15fps. If you want smoother videos, it should be at least 60fps, which is why I do the annoying recording in front with a cellphone at 4k 120fps.

Did you compose the tune yourself? It is catchy.

What synthesizer did you play it with?

Aside from the "fun" aspect (video games, turning your scope into a "TV", etc.), Z mode is still being used by quite a few people.  I'm not sure I'm allowed to say who is still using it for what, but I would be interested in hearing from people who (would) use Z mode for "serious" applications.

My Agilent has only blanking, not variable intensity.

"Blanking" can also be done using an external trigger-in signal (if available).  This is one way of creating constellation diagrams without a "true" XYZ input (and what I used in this short video, since the RTM does not have a Z input either)

hi, no, oscillofun is by Atom Delta, and potential is forever is by Chris Allen. I just click play on the music player and record the oscilloscope screen :p

i need an analog Z input for testing old arcade pcb's properly,
my old D83 RACKMOUNT is huge and heavy - i'd like to replace it with a modern scope, but i must have variable blanking - trigger tricks of on/off blanking isnt going to do it

Telequipment ?

Nice CRO using a Tek 7603 CRT providing a very crisp trace.
Was my first scope.

I recorded my demo by playing the youtube video into my 'scope.

I don't know if youtube audio compression would have any effect.


If anybody has an mp3...

Yeah, you need better quality. You can download wav files here: https://drive.google.com/drive/folders/1UHvGC6-TDywFri7am8YJl5G6svK33qhC

PC sound card to scope good enough?  Wouldn't think with audio, we need much?   Seems I tried it before with miserable results.   PC scope software out performed it by a mile.

Probably fine, assuming it has good volume level and sample rate. Not sure how much the latter matters, but some files are specified.

i used my pc's built-in audio output for all the recordings, it's not bad as long as you don't use an equalizer or other DSP for your audio out
