Inside the new Rigol 7000 Series oscilloscope with custom ASIC's.
Also a look at the bootloader code for potential hacks.

Wasn't it determined in the past that Rigol was using resistors to indicate hardware revs but they aren't actually connected to anything?

Looking forward to the hacking thread(s). :-/O :D

Looks like that mesh has cutouts that perfectly match the notches where the fan clips in and where the IEC connector sits.

many designs use that. they use the vision recognition systems down the line to see what flies by.

So it does, well spotted

Shouldn't turn it on for too long without the fan in place Mr. Jones!

I don't like Rigols: the UI is a disaster. They're cheap, though: lots of bang per buck. But this one isn't cheap so... what's the point?

The Rigol UI kept bothering me too. Lots of lag in places that should be smooth and lots of UI inconsistencies. Extremely laggy software-based serial interface decoding... So I eventually sold my 1000z and went for Keysight MSO2xxx, which is in the same price range as this 7000.

The same reason why I hate Tek. Keysight scopes are REALLY incredibly responsive.

There's hardly anything on the pcb !!

I bet you Tektronix and Keysight never saw this coming !

The chinese are slowly moving up the scope performance ladder. Won't be long before they are making scopes with GHz front ends !

cheers

It might be a bit misleading to check the heatsink temperature without the airflow it was designed for, otoh checking if a failing fan triggers overtemperature protection imho is worthwhile.

Thanks for showing!

Isn't that just what the 7000 series offers ?

The Siglent SDS5000X 350, 500 and 1 GHz models will be out in a month or two as well.

Has Siglent rolled its own ASICs yet ?

Interesting that they relied on so much onboard generation for the individual voltage rather than use the power supply for at least the sundry voltage like the 5v rail. Seems like wasted board space on an expensive board.

The board does not look that cramped - so in a budget product they could have reduced board size a bit (e.g. 50%), but this is not such a bargin product. They may need the spacing anyway to get to the other side of the case and more spacing also helps with cooling. The board may not be that many layers and this that expensive.  It is a different thing in the 1054 and similar, where every dollar counts.

We may find a more cramped board in a future version with maybe additional features (e.g. generator).

Noticed this as well. Considering that the fan sucks air into the scope, i guess the mesh was intended as dust filter.
I have no clue why they stuck it on the metal instead. Not sure if this intentional or not, but if it is a screw-up i would be surprised that Rigol didn't catch it during pilot production.

That honeycomb on the back reminds me Rohde and Schwarz design.

Is the PSU off the shelf one?

For this price I would have expected a better quality fan. Recently I replaced an Adda fan because it started to make rattle sounds after a couple of days worth of operating.

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