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... ;)
