New Scope Demoboard from Batronix

[axantas]

What I find a pity about the demo board is that they couldn't keep the price below €200 in the long term.
In the beginning, at least a lot of people "here" ordered the board, which I thought was great, because we all have the same source here, so it's easier to understand the problems/measurement situations of other users.
A board as a reference, so to speak.
So please make the board more affordable again.

You're probably right. As this is a really great forum (and there are so many great people here) we have set up a coupon code.

With the coupon code "EEVblog" you can get the demo board in the Batronix online shop for the introductory price of 159 Euro + shipping + VAT again. The shipping costs + VAT are calculated by the online shop depending on the country of delivery.

We could also have called the coupon code "ThanksToMartin72", but that would certainly have confused some people. 

I am already experimenting with this board, but Batronix just earned 10 additional stars in my next Google review for this presence at your customers - there is a one for a DHO914 pending...

I received one and have begun using it.  I make cheat sheet to help with the switches.  And, a note to young players, use J4 and not J5 for viewing the 50kHz and 100kHz Hz clock signals (that mistake cost me some time).

Working through the demo board manual ... thought I'd share these:

Interesting demo for using Channels 1 and 3, rather than 1 and 2, for better performance.

Which point is that?

This appears to be a 2000X HD. I suppose, we know, why this is that way. Dave shows it in his teardown video. It is due to the routing of the PCB. CH1/2 and 3/4 share one ADC:

Looks like "CH1&Ch2" suffers from aliasing (signal not sufficiently bandwidth limited for 1GSa/s).

[Martin72]

Yep, he should try to measure it again with 200Mhz bandwith limit(if avaible).

[Grandchuck]

The scope used is the SDS2204X HD which has a 200 MHz bandwidth.  As shown in Dave's video, Ch1 and Ch2 share one ADC and I am thinking this explains the result.
 Martin, I am on page 48 ... it has been educational.  Thanks for alerting the forum about this demo board.

Here is the delay from TP1 to TP6 on the demo board.

[Martin72]

Nice,

I hadn't even tried it yet.

Cursors are bit outdated nowadays, especially in an analytical DSO. What about using the automatic FRFR measurement instead?

[Grandchuck]

Done!  Still learning.  This is going to take a while. 

[Martin72]

Martin, I am on page 48

For others, this is the "Hf Test Track" section.
Mainly responsible are two fast risetime logic gate ICs (tr<450ps), one IC is directly connected to the RF out BNC socket, so that you have a quite fast pulse at the start.
The signal also looks pretty clean.

Is that SDS1104X-E stock (100Mhz) or hacked to 200MHz?

[Martin72]

Hi,

100Mhz "untouched", loaned from work until new scope arrives.

2k HD gone to someone else already ?

[Martin72]

Yep, two weeks ago.

[Grandchuck]

The end of the Batronix manual ... reflections in coax.  The coax length is 41 inches.  Three conditions are shown.

I will be going back and changing/trying more experiments.  Conclusion: the board is well engineered and executed.  The manual is as good as can be expected since different instruments will have to be set up in their own fashion.

Martin would like a lower price and who would argue?  However, given the sales volume it might be already priced as low as practical?

I took the demo board to work today and connected our Lecroy WR9054 (500Mhz) to the Hf-Out (J7).
Indeed, this is a very fast signal, demo board owners have a "small Bodnar pulser" at the start, even if "only" in the upper ps range.

It is faster than that...

Estimate cca. 270-280ps ...

Measuring 480ps on scope with 400ps risetime. 500ps on scope with with 420ps risetime and 521ps on one with 440ps risetime..

Used good quality 200mm cable.

[Martin72]

Nice...

First I was a little bit irritated - Another lecroy ? 
Second look, thank god a siglent..
With 4GSa/s...

One will be in Martin's camp very soon. 
Shame his SDS2000X HD had to make way for it.

[Martin72]

Shame his SDS2000X HD had to make way for it.

To be honest, it wouldn't have been necessary.
At first glance, but you can imagine why I did it after all in view of the upcoming 3000 models and their prices.

Still that would be a bit of coin tied up in 2 good scopes. 
3034X HD is little more than 5034X but 12bit and the same size 10"nice 12" display.
Excellent upgrade IMO. 

Correction made.
