New Scope Demoboard from Batronix

[JOSM]

Mine arrived two days ago. I have tried some of the different options already. And they work well. The manual is very good indeed. I do not regret my purchase.
I would like to use the board to show younger people how to use an oscilloscope. But it is not easy to find interested ones.

Nice too see this scope between all this high end equipment. I also own an old HM2008 Combiscope. I wonder how the demo board signals are looking on this... 

I'm still amazed that the old Hameg scope does averaging:  I think the max average count is 256 (in steps of 2^N), but even at lower numbers of averages, it works pretty well.  That said, I think that it can only test about 10% of the Batronix demo board functions, which says a lot about how far we've come in the last few decades.

Oh, and it also does a really nice job in XY mode

Today, better a few minutes ago, I check the bodeplot and XY demo.
For the bode plot the demo board got a lowpass and bandpass filter, I didn´t check if its an active one or passive.
Connecting is simply: Output of the generator (in this case the built-in of my HD scope) into the filterinput via bnc, then one probe to the testpoint "In", the other to "BP" or "LP", thats it..
I´ll follow the suggestion of the manual and adjusted the range between 200hz and 10Mhz.
Then checking XY - something I never used before 
Therefore I was a little bit surprised, how less you can do/adjust in this mode.
Also that I must change the connection of the scope, before it was Ch1 and Ch4, but that won´t work, it must be Ch1 and Ch2.
Known stuff for other, but new to me..
Nevertheless, the setup is simple and worked immediately.
Pics showing the demoboard´s BP at 5khz and 1khz (you can play along with the frequencies on board).
The displaying of the XY and the channels simultaneously like in the screenshot of the manual seems not possible on the siglent.

Then checking XY - something I never used before 

Just yesterday my video on XY mode was published on the R&S YouTube channel



In my experience, most people aren't aware of all the different ways of using XY mode.

I'm also doing a video specifically on Lissajous patterns, but it won't come out for a couple of weeks.

[Martin72]

 

Being able to see the two channels involved at the same time with the XY display I feel is an advantage.
This would be a nice feature update for my siglent scope.

I got my board in yesterday, and I was thinking about trying it out next week. Then I remembered I only know a few words in German (some aren't even swears!). Maybe I'll google translate it with my phone lol.

Bode and XY on the siglent sds1104x-e...
For Bode I need my sdg2122X generator, works without problems via usb.
XY mode is exact like on the HD, simple..
BTW:

For the bode plot the demo board got a lowpass and bandpass filter, I didn´t check if its an active one or passive.

Now I know it, it´s passive...I´ve forgotten to power the board on while the Bode test runs..

(For siglent:
There´s no mode to run the plot once, right ? It´s in an endless-loop until you stop it.
And: It is faster than the HD, reacts faster and when you want to leave the mode, it stops almost immediately...)

I'm not sure which scope you're referring to, but on the SDS2504XP in bode setup, there is the option to do continuous or single.

Hi,

That one doesn't have the same option? It's been a while since I've had that scope.

[pdenisowski]

Can you provide some more info on those demo boards that are not for sale?

Here's the (very short) user guide for our most recent scope demo board.  It's actually has a lot of functionality, but isn't something we sell as a product.

This would be a nice feature update for my siglent scope.

Being able to see X and Y together with XY is pretty useful for making sure your settings are correct.  I posted a short video of XY on our RTM and to the right of the XY display you can see the IQ values on the X (yellow) and Y (green) channels being updated in real time

The translation is complete, you can download the English manual using the following link:

Furthermore, the Demo Board website is now accessible in English as well.

Great! My board came in today.

[2N3055]

This is way more stable than mine, I´ll make a short clip in the next days.
And: As I mentioned before, my siglent decode it correctly, you can see it best when in stop mode.

Board came today...

I confirm SPI data coming of the board is jittery...
Also there is no deterministic timing between CS and clock and rest of data.

But it is not in violation of SPI protocol.
Decodes fine.
To get stable trigger I did nothing special but triggered on clock with holdoff or SPI protocol trigger that will align data decoded to clock.
That will give stable left edge. Rest of packages and signals will not align or overlap because they differ in position and timing...

If I set trigger for just one SPI packet data type (for instance MOSI 52 6F hex) i get same packet that does not have uniform timing.

SPI is definitely bit banged and interrupts are, well, interrupting...

[Martin72]

But it is not in violation of SPI protocol.
Decodes fine.

Yepp, that was also no problem here.
Today I´ve tried again on a lecroy(WR9054) and got it reasonably stable (timebase 200µs/div, 200kbit/s) with timeout appx 7.4µs("pause" between the clocks), last trigger.

[Andre77]

About the jittering between data words: The microcontroller on the demo board has different interrupt sources with different priority. The interrupt for the "function generator" DAC is treated with the highest priority. There, the 1-data word buffer must be refilled in time before the next data word is output.

The interface interrupts have a lower priority level than the DAC. Different time spans can lie between two data words. This results in the jittering that looks choppy but also more realistic like a real microcontroller application. This type of jitter between data words has no influence on correct data transmission/decoding.

[pdenisowski]

I have five new YouTube videos sitting in my post-production queue (including, of all things, "Getting Started with MXO Series Oscilloscopes - Triggering Fundamentals")

The triggering video is now live.  I created a lot of the screenshots using an ARB, but a demo board would definitely have been faster, easier, and cheaper for several of the triggering examples.

Arrived today, the printed manuals...

[JOSM]

Arrived today, the printed manuals...

How to get a hold on a copy of the printed manual? I cannot find an option to order one on the web site.

[Update 1 July 2023]
The printed manual arrived yesterday. 
I did not receive an e-mail asking for the need of one prior to that.

[Martin72]

Hi,
If you had previously purchased a board, you get it forwarded, AFAIK.

[techneut]

good morning,
after I ordered the demo board I got an email asking if I wanted to recieve a printed copy.
I answerd with yes, please and now it is on its way, hopefully will be dilivered today.

Regards, Ronald
