content: Hi,The topic seems to be of interest at the moment, I also think it's a nice gimmick and it's a shame that the results will "sink" into the respective oscilloscope threads.Hence this thread for it.Post your results, name the settings, the "music" material used...I will post my results with the SDS824X HD here again this weekend.Martin

content: Here's a copy of my test from the 2kX+ thread:I bought a copy of OsciStudio to test this out, and eventually make a very stupid video.In the meantime, it was useful to test both refresh rates and audio frequency effect on the XY results:The first section is more obvious, that's scrolling through refresh rates (first 50 seconds). The last 30 seconds is screwing around with the frequency of the shape. Chris's tutorial shows him using A1 at 55Hz, which is (one of the reasons) why my results aren't as great with his music. A4 at 440Hz (and really most notes over ~100Hz) show much greater stability on my scope.Here's my original video with the music:10kpts for the memory to keep it faster/smoother. Going up higher either adds weird thickness, or slows it down. Timebase: 10bits, 100us/div, 10kpts, 10MSa/s; channels at DC50, 300mV/div.

content: In case anyone is wondering, here's the physical setup of the "measurement". Two pigtail coax soldered to 3.5mm jack, and connected to 50 ohm terminated scope input.Using the high quality source music file (usually .wav) provided by the artist is very important. Play it back at the highest possible bitrate and resolution. The audio from the youtube videos won't get you clean results.Audio DAC : Fiio KA3 @ 96.0 kHz, 24 bit, 3.5mm stereo output into coax and scope 50 ohms input.Scope settings:Input settings (CH1, CH2) : 50-ohm termination, DC coupled, 20M BW limitTimebase : 1 ms/div, 1 MSa/s, 10 kpts memoryTrigger : Auto, alternating edge, CH1, AC coupled, 0V offsetAcquire : XY mode (duh!)Display : Color grading onTimebase is interesting, I find C.Allen's music to work best at 1 ms/div, 1 MSa/s, 10 kpts memory.Whereas Jerobeam Fenderson's music seems to work best at 2 ms/div, 500 kSa/s, 10 kpts memory.

content: I found one trick that made graphics rendering more consistent is to feed a fast waveform (e.g. 1MHz sine wave) to a spare input as the trigger source, to force as fast an update rate as possible on the scope. This ensures as little dead time as possible between triggers, and that the waveform update rate is consistent.Also, this avoids situations where the graphics is just a dot, or a vertical/horizontal line, the waveform does not update unless in auto trigger mode.The improvement in graphics quality from this arrangement kind of makes sense, as XY mode on analog scopes is just a completely continuous vector plot without triggers. So by actively forcing the waveform acquisition to trigger unconditionally with as little dead time as possible, the graphics rendering would be the closest to what an analog scope could produce.By feeding a 1MHz signal from the scope built-in AWG to the external trigger input, I could achieve 46.9 wfm/s , when the timebase is set to 10k sample memory, 500kSa/s, 2ms/div. The shroom on my screen looks really nice.Side note 1: Listening to the original quality audio tracks with earphones is a trippy experience, the data modulation audio pulses hits your ears like no other music. I imagine this is what the life of a RF demodulator sounds like.Side note 2: A discussion on analog graphics rendering capabilities of digital oscilloscopes, what a time to be alive.

content: It was suggested that triggering from a 3rd channel might help with performance. I setup CH3 with a 1MHz sine wave, and set the edge trigger to that channel. I activated and deactivated my AWG and saw no change whatsoever with the performance. Triggering in general hasn't shown to have an effect here IME. At least that's how it is with my scope. 🤷

If you pause the video and advance it frame by frame by pressing , and . on your keyboard, you'll see the screen does update at 60Hz, with new content on the screen every video frame.Edit:Quote from: joeqsmith on April 14, 2024, 12:23:50 amAnother question that could also be asked is how well the multiple acquisitions made between every screen update are presented to the user on the screen. Scopes with good "digital phosphor" tech will stack the multiple acquisitions made during each screen update, and use brightness intensity to convey how often the multiple waveforms overlap a single point on the screen.I don't think LCD screens on most scopes with 8-bit color depth and uniform backlight brightness can match the display dynamic range on a phosphor CRT, but I guess one could use antialiasing techniques and good gamma curves to convey more of the frequency-of-occurrence information within multiple stacked acquisitions. Color intensity grading can also boost the effective dynamic range of the display by using all the color channels I guess.In an ideal world, my scope would have the retina, 1000000:1 contrast ratio, mini-led local backlight, 1600 nits, 144 Hz display on my Macbook, plus the 4.5 million wfm/s update rate on the R&S MXO4, plus a really good digital phosphor implementation, to show me every bit of detail in all the waveform samples.I wonder how one could quantitatively measure the performance of an oscilloscope in this respect. But I digress, this thread is about how well scopes can rock and roll.

(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.

WaveStream mode operates at up to 10 GS/swith an update rate up to 8000 waveforms/second for bettercapture of higher frequency abnormal events.I had tried this with the X-Y mode but it made matters worse. My other scopes don't offer this feature.Recently Ncticro made the following comment:QuoteFollowed with:QuoteI agree that my 18 YO scope is indeed much slower than pretty much every product shown in this thread.

content: It will go in that direction, because my assumption turned out to be wrong earlier.With the Scarlet, I used the line out outputs, with the Fiio, I used the headphone output, which is probably lower impedance.So I connected the headphone output of the Scarlet earlier - the result did not change.At least you would now have the “proof” that higher sample rates/bandwidth have a clear advantage, at least with this type of “music”, even if you can'thearit yourself.

It supports up to 768kHz PCM and DSD1024. DAC is fed by microcontroller in device that serves as USB device and does translation.My point is that output amplifier is very wideband, and DAC is also.So if done right, it is capable of rather good phase/frequency response. DAC itself has many configurable options, including programmable FIR filters, even some distortion compensation circuit (some sort of feed-forward digital linearization filter)... Line out opamp seems quite good, fast and very low distortion.Altogether better in theory than Focusrite outputs....

content: one curiosity about the keysight 1102g is that the display's pixels don't seem to be perfectly square, so in the real world, the circle you'd get from two sine waves 90° out of phase looks more like an ellipse in real life than in a screenshot. the non-squareness of the pixels is something i notice only when in XY mode so i thought it would be worthy of mentioning in this topic since oscilloscope music is all about the XY display capabilities of the scopes, and not having a truly square representation in that mode can be at the very least mildly annoying. this is something that i notice with my eyes and also measured in the past with a piece of paper i cut to the size of the bottom edge of a division, so it's not camera distortion:using the square crop on the photos app it's clear it's far from a circle:and in the scope's screenshot it's much closer to a circle(there might be something going on with the audio output on channel 2, i didn't use a wavegen for this, just my pc sound card as i had it plugged in for the song recordings):and the divisions are clearly square on the screenshot:but on the photo it clearly is not square:(first time trying inline image posting, it might not work at all cause the preview isn't working and yeah. took like 5 tries to get it right)edit:i measured the display to be 155mm by 87.2mm and that's a 16:9 aspect ratio, where 800x480 is 5:3 or 15:9 if you like to stick with the 9 for vertical, which means each pixel is stretched horizontally about 6%

content: Siglent scopes do not support variable timebase. Many scopes do not.I know Keysight does on Megazooms and I think some Rigols do.LeCroy, Micsig, and some R&S I looked into do not. I don't think Tektronix supports it either, on scopes I remember. But Tektronix might have some scopes support it and some not, because of various architectures over the years.As an information, those that support it do it by still sampling at same 1-2-5 (or some other fixed) increments and just showing only part of the data on screen. So 33 ns/div will be sampled at 50ns/div and only first 330ns will be shown (if there are 10 divs on screen). So no sampling benefits of being able to chose finely how scope will sample. In fact you will have even more blind time in this case.To me, most useful fine timebase is when decoding serial protocols on my Keysight. But that is mostly because screen is so small and you want to maximize useful part you are looking at. With much larger (10" and above) screens I don't find it that important. I just make sure what I need is somewhere on a screen in full and it is legible enough.

content: Quote from: Anthocyanina on April 07, 2025, 07:48:02 amAD is not representative to how most scopes work. It is slow ADC connected to FPGA and it streams raw data to PC for everything else.It contains only triggering onboard. All waveform processing is on PC from a streamed data. For such systems it pays for "sampling head" to aggressively decimate data to be sent to PC. It is 32ksamples buffer anyways.On real scopes you have hundreds of MS buffers. Even cheap SDS800xHD has 100MS buffer.So you cannot brute force it. It needs optimizations in processing.Scopes do not actually change sample rate at all. Most ADC only accept limited clock ranges. Their ADC sample all the time at the fastest rate. That is being feed to trigger engine, and after that (or in parallel sometimes) that data stream is then decimated to achieve equivalent of slower sample rate.Decimation is usually done by simple discarding of some samples. So you keep ever 10th of samples on 1 GS/s sample rate and you get 100MS/s equivalent. You can discard only integer number of samples, but usually it is something that nicely divisible. FPGA has to process huge amounts of data, and that is done by logic that is preset to some fixed values.Digital circuits and processors are very efficient if you round it up to some fixed values. Multiply/divide by 2 is achieved by simply shifting binary number left and right. DSP block will favour certain data sizes...
