Cheaper then decode options on some scopes

It's not like they depend on the performance of any other third party components in this design amirite?Only offered as an observation.Over the years there have been a # of threads here with failures of scope PSU's, in many cases they have not been made by the scope manufacturer. Could you call this modus operandi a weak link ? I do.

When will the scope actually be available?
- Why do we have two optocouplers ? Isn't one enough ?

See the directions of information transfer. I doubt it - ....The second optoisolator is probably carrying the 'line trigger' signal from primary side to secondary side.

cat /proc/cpuinfocat /proc/meminfo
find /
You had a full blown shell on the prompt there, ash is the shell. Try run some of the following to get some interesting information out:Code: [Select]cat /proc/cpuinfocat /proc/meminfo
And you can list all the files, provided it has the tool installedCode: [Select]find /

Nice review. I find the multi-layer board completely mind boggling. Is that routed by human, computer or magic? It's also completely awesome that those many layer boards are becoming such commodities.

Rigol Should build a 4 channel one using similar hardware to this, why they did not do it 4 channel, they have the ADC and the ZYNQ, they just needed to add the front end
