A little bit of diligence and I got a scopecase. It is created on the SKB1914-08 basis. The suitcase holds both digital probes, five analog probes, additional cables, a multimeter and a box for tools/parts. The oscilloscope can work inside, there is unobstructed ventilation.
Ironically, when photographing the oscilloscope, a small defect was found. At a 20 ?s timebase the zoom has an error. This is manifested if the channel operates without its own pair (1-2 or 3-4).
I'm guess I'm missing your error. I see your 20uS/div waveform, then your zoom at 10nS/div. your 10nS/div has a little ring on it then looks flat out till at least 60nS. Problem is, we don't know what happens after that ( except that it falls at some point ). To me, it looks like that 60 nS zoom you have can fit on the peak of the 20uS trace you have. Same can be said of what's leading up to that.
Did I miss what you are seeing?
Is the bug you are referring to the horizontal offset from the trigger position? If so, are you using probe de-skew? I found that using de-skew only moved the waveform but not the trigger, causing this kind of issue (referred to in my previous bug-list post).
Trigger skew looks like it. Looking at things again, the trigger level looks to be set at 0V but the zoomed view is skewed 4 nS.
Just using channel one I could see the same offset but I also noticed that sometimes there seemed to be no offset. I captured two scope shots, one showing the offset and one with infinite persistence on showing the proper timing and with offset. Notice nothing in between.

Yes, this offset is 4ns, rarely everything is fine. And no, I did not use de-skew.
Everything falls into place if you turn on the second channel. Try it.

Hi MikeP - this is a bug that is fixed in the next release.

Thanks for your engagement Rich.
Any ETA for the next firmware update release?

Sure - I enjoy this forum, so it is easy to engage when I know an answer.
And I knew someone was going to ask when to expect the FW
I always hate to give a prediction, but I believe we'll see a new FW in October (which could mean the end of October - all depends on how testing goes).

I wish R&S had added a VESA mount but may be someone else here has a brilliant DIY solution?

The back case feels too flimsy to take a mount- you could probably make a mount from an angled metal plate for it to sit on.
maybe see if there is a VESA keyboard shelf that could be adapted?

Hi Ghislain,
please send me a personal message and I will send you the mounting instruction for the ZZA-RTB. It's not the direct answer to your question, but you can see the mounting procedure of the RTB in a rackmount kit.

From the pictures it looks like the honeycomb like structure allows for great airflow but does not necessarily support structural rigidness of the enclosure, let alone attachment of a VESA adapter.
The VESA keyboard shelf is actually a very good idea, I found this:
https://www.amazon.com/SDS-Aluminum-Keyboard-Mounting-Manufactured/dp/B00ZGFYJQK which seems to fit the bill.
Now it is about finding a means of safely securing the scope to the shelf, the last thing you want is that while moving the shelf, the scope slips off or topples over

Concerning the 'glossy' screen (haven't read all the posts but I've seen some commentary about it):
In this video:
one can see a perfectly reflection-free screen on the RTB2000. At 1:05 you see which anti-glare cover was applied. I've ordered exactly
this product at Amazon Germany (the single review there giving just one star seems a bit stupid to me. The video proves how good it actually works).
I used this one (from Amazon US) on mine (based I believe on mikeselectricstuff's original suggestion to use an Amazon Fire 10" screen protector) - works like a charm:
https://smile.amazon.com/gp/product/B015IKUNL2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1I cut it using a paper trimmer and a corner cutter for the corners. Applying without bubbles and dust takes a bit of attention, but 100% good (and these usually come with 2 or 3 protectors, so there is room for trial-and-error.
I tested the one that mike recommended, and can confirm that it worked very well (especially if applied with the front of the case off, allowing it to be tucked under the bezel).
I ended up removing it though, as a) I got some dust under it when applying it which annoyed me a LOT, and b) where I have the scope there aren't many reflecting light sources, and I preferred the slightly sharper image with the glossy screen finish rather than the matte. I'd definitely put one back on if I moved the scope to where reflections are an issue though.

Congratulations
I did it too, but in two steps for now:
RTB2002, 70MHz
and
RTB-PK1 Option Bundle, that is
- RTB-B6 - 25 MHz Arbiträr Generator
- RTB-K1 - I2C/SPI Decode
- RTB-K2 - UART/RS-232/RS-422/RS-485 Decode
- RTB-K3 - CAN/LIN Dekodierung und
- RTB-K15 - History & Segmented Memory
third step in the future will be
- RTB-B1 - 16 Kanal Mixed Signal
step by step, please
Are there any known discounts in the EU/Germany for anybody or students?
I'm hoping that there is a significant discount if you buy an RTB2004 with all the options. There ought to be since it's all software license keys except for the LA probes.
The other scope I'm considering is the GW Instek MSO-2204EA. It has most of the same features, but neither the memory depth nor the BW. Probably good enough, but 300 MHz and 140 Mpts would be really nice if the uptick in price is not too high.
