Doesnt appear to be any 4 channel versions (no space on board), unlike the older HMO compacts.

I noticed the Hameg branding on the pod.

It's crazy to see that this top level oscilloscope cost the same as mine bottom level one, which I bought many years ago.

One minor annoyance I noticed: The measurement readout is left-aligned and they aren't using tabular figures (all digits are of the same width). So when the reading changes, the unit jumps in position. Also, when changing between 99 and 100 the position changes significantly. They've got the space available to right-align the measurement results. Wondering why this slipped since they seem to be very concerned about user interface.

Appendix:
I've taken a look at their open source acknowledgements, looks like they're using FreeRTOS. This explains the fast boot time.

I want to buy an oscilloscope, but are undecided.
This R&S oscilloscoper is great but has little memory only 2M

I thought the new siglent SDS2000X  has 140M !!

what to choose?

I noticed a little Y on the PCB ground plane (which is not connected) next to the sample memory (18:45) and I was wondering, if that is some sort of a sign for the Pick & Place machine? Is that common? I thought, they would do it with silkscreen markings or so.

Just another great scope out of my price range  :(

Really looks and works well from what I see. I to agree about the layout though would be the only negative on this.

Overall well done R&S

Looks very clean and well made (who doesn't love gold contacts).  For my purposes, I cant see a reason to spend that much more for what seems like less impressive specs on the datasheets compared to the 1054Z.  Besides having a nice UI, will there be any noticeable difference when using this by choosing this scope over a Rigol 1054Z (assuming purchasing the 100Mhz version of R&S scope)  :-//

Also it says its a MSO built in which it sort of is but it is $375 just for the probe you need for it to work...  I guess that way you could get the scope at a lower price and then add MSO as an option.

I have the "older" HMO 0722 scope which I think is very similar apart from some minor UI changes. For me it is important to have Y amplifiers with very little noise at high sensitivity (1/10 mv/div), the Hameg is very quiet. I somehow doubt that the Rigol for ~400 bucks would have a similar quality frontend.

Which parameter is 1/10 mV div? Do you mean the noise is 0.1 mV or do you mean the lowest setting is 0.1 mV/div ? Or do I get it wrong altogether?

I meant between 1mv/div and 10mV/div.

You are correct, even the 2 channel 1000X has 14M and a 500uV input range.

Just wait until you see what R&S charges for the decoding and other options! The base prices are loss leaders!

@salviador: Whatever you do: don't buy the SDS2000(X). It won't make you happy.

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Watching the teardown videos, I have learnt how to understand what good design is.

Thank you for the videos.  :-+

You never do fiducial markings with silkscreen, there can be alignment errors.

What is it with the via's on the board? They look white..

Are they filled and then covered with some solkscreen? :-//

And why do seperate fiducials for the bga's? 4 marks in the corners of the board should be enough right?

If they bundled the probe it would probably sell like hot cakes.

All the options together (UART, CAN, I2C, SPI and logic channels) cost 1335 euro extra (including VAT).

Damn, that sucks.
The HMO1002 is bundled with the serial options now I believe.

A drool-worth scope, but more than I would want to pay. One question that I didn't see asked before - what is the coin cell for? That is a drawback, having to worry about remembering to change it out years down the road. I hope it isn't keeping something important (like cal values) backed up.

Almost certainly just real-time clock. I heard Dave mention something about FRAM during the teardown, that's probably what they're using for cal data - IIRC that's what Rigol uses as well.

I would like to see this thing run against the Rigol DS2000 to compare its capture performance. Price wise for 300Mhz it is virtually the same as a Rigol DS2302A which is $2450US on Tequipment. Compared to other big names you can also go tektronix and spend over $8000 to get a 300Mhz scope that was obsolete 10 years ago.

Personally I think the Rigol is much more attractive but beauty is highly subjective.
