You have got 500MHz DSO with this FW, but SysInfo show DS4014? Do you already have frequency response tests?

Is it possible to upgrade MSO4014 to MSO4054? Is the HW 100% identical? Has hack confirmed to be working not only in GUI, but also in actual frequency response test?
johna:
You can test it with any digital signal that's lower. On 100 MHz scope if you watch 100 MHz square wave it'll look like 2 summed sines:
although maybe you can't capture much of the second harmonic.
I think even 40-50 MHz square wave will look that way on 100MHz scope. Maybe the clock output from a microcontroller...

Thank you very much! As soon as free time, I will try to do tests on the job's MSO4024 up to 2GHz. Can you make a patch to 350MHz test?

You can't uninstall options by installing other options instead. You need to use the SCPI command :SYSTem:OPTion:UNINSTall command to uninstall keys. This has already been mentioned several times in this topic.
If you're not familiar with SCPI commands, read your scope's user's manual + programming guide, both documents has info about SCPI commands.
You can search this topic for :SYSTem:OPTion:UNINSTall for more info.

It's been a while since I've monitored this thread and it appears plenty of progress has been made. Excellent work everyone!
Took the opportunity to mirror a bunch more useful files permanently at http://www.gotroot.ca/rigol as well as setting up a cron job to pull down the complete thread every day as well. If there's anything else that should be there, send me files or PMs and I will make it so.
