Firmware for the DSOX1204x series is now posted on the Keysight website. As this scope runs linux it should be interesting to take a peak at.

Version 2.01
https://www.keysight.com/main/software.jspx?ckey=3023906&id=3023906&nid=-32110.1258590&lc=eng&cc=US

Release notes:

Enhancements
- The following Frequency Response Analysis (FRA) enhancements were added:
o The sweep frequency range is no longer limited to decade values – it can now be
set to any frequency within the WaveGen’s limits.
o The “points per decade” setting has been changed to “total points” for ease of use.
o FRA Chart:
 Minor gridlines for the horizontal axis are now shown to improve readiblity
of the plot.
 The chart’s horizontal display range is now independent of the Start/Stop
Frequency setting in the Setup Menu.
- Boot-up time was reduced.
- Improved the color constrast for Channel 3 and Channel 4’s waveform persistence.
- Miscellaneous LAN enhancements.
Bug Fixes
- Fixed missing “Time Reference” softkey.
- Fixed an unused softkey briefly appearing in the Pattern Trigger menu.
- Fixed an issue of the inverted channel mode not displaying the waveform correctly in
Averaging Mode.

I am curious about how much hardware it shares with the 2-channel 1000X scopes... no teardown yet?

It's been surprisingly quiet.

Well, Mike has one and he has posted internal pics earlier in this thread. It is based on the same hardware platform as the 1002X series scopes, very similar platform. I don't know if anyone has done a video tera down, though.

Please excuse my ignorance, but what does the acronym BLT mean for that board?

Internal shots.

A quick side-by-side comparison with the 1102 :
Bus and Ref buttons have moved to the Analyse menu
Has LAN interface, but remote front panel not yet implemented. PHY is SMC 8710A, so 100Mbit
Ridiculously long boot time - 55 secs v.21 on the 1102 - maybe still some debug code in there ? FW is V2.00
No WinCE license sticker on the back
Low-level noise performance identical.
Ref and FFT have dedicated size and position knobs, presumably to match the knob layout of the 1102. Not sire I like that these are on the left.
Still has external trig input on the back, but can no longer display it, which is as expected
The BLT board has gone to rev 3 but looks pretty much identical at first glance, apart from J104 now being fitted.
Might be interesting to swap into the 1102G...

I found an interesting article written by Daniel Bogdanoff about the making of an ASIC.  There is a picture of the same one you show in the article (revision 2 instead of 3) but it does not have the heat sinks on the chips.  In case you want to see them.

Thanks for a great read, Daniel!

Dave did a teardown of the DSOX1102G in March 2017.  You can see  in the chassis holes the future planning for the DSOX1204G.  Comparing Mikes pictures of the 1204 with the EEVblog teardown of the 1102,  the Main boards are labeled different.  DSOx1000AG vs DSOX1004AG.  It seems the 1004 board is a bit more complex.

Shouldn't be mission impossible to devise workarounds... ;)

The .ksx is a initrnamfs file which can be easily opened with 7zip decompressor.

Would someone who owns or uses a 4ch 1000X confirm if its automatic measurements also include statistics of these measurements, like min, max, current, mean, std dev, count etc? This was mentioned in the 1000X datasheet as "Measurements continuously updated with statistics" on page 19 but not mentioned at all in the User's Guide. I also have not noticed it from any demos, reviews or YouTubes I've seen.

Thank you.

Upon a quick check it looks like no, but I could be missing it somewhere..

Thank you for checking.

If stats were there, they would be somewhere buried in the measurement menu tree. I checked the user's guides of the 1000X, 2000X and 3000X and it is only referenced in the 3000X, and it is actually there on the scope. Funny it would be in the datasheets but not in the manuals or the machines.

Upon a quick check it looks like no, but I could be missing it somewhere..

There is a 128 byte sw-description.sig file.  Anyone knows how it is generated?  It is different on each install package (.ksx)

I own the EDUX1002G, then purchased MSO5074 from Rigol... for me, it is not near the usability of the Keysight... it can be hacked to have tons of features, but it is slow and the serial protocol decoding a toy.  I am about to return it

The EDUX1002G hacked and with some hardware mods can have 2.5 channels and it is a pleasure and fun to use.  The Rigol is giving me headaches, you don't know what you are getting from the scope, you are always wondering if what is showing is accurate or not.

Do you have specific example ?
It is not so easy to have scope on loan without losing money and I am open minded so if it is possible to have examples. I am interested.
I am also interested in what you criticize for the serial decoding on the Rigol ?
Before receiving a shitstorm on my head, I specify that I am really interested to know in what the Keysight is superior on these aspects.
I am not here to support Rigol, just to have examples from real life.

Thank you :)
