Additionally, there are no CFL lightning devices in my place I really hate them! The only source of EMI is my own body; but wearing an ESD wrist strap the interference is minimised, as it can be seen on the "Noise 2" figure, above, where a few millivolts p-p of the 50Hz hum my own body was picking up were added to the VHF internal noise of the device. The problem is that my previous unit did not have any of those issues. I could just probe any test PCB and read nice, noise-free waveforms. Using a better lower noise, x probe I had even sharper edges and cleaner lines.

Background: The hack itself is simply updating the serial number and the model number but does not work anymore on Rigols with firmwares higher than SP2, this guide has the files needed to downgrade to SP2 , change the serial number and the model number using USB and then to upgrade again.
The downgrade is currently only possible for scopes who come with an firmware up to So do this at you own risk. This will give the current firmware not the full version string and some other info. The hardware version will also appear next to "Hardversion". Note if this is 57 or lower or Be aware!!!!!!! Make sure you use the " VISA version " one if your scope is older and you had this already installed. When in doubt deinstall and re-install.
I uploaded the one I used to rapidshare here 12Mb. This is the version that came on the cdrom with my scope which says version " Do NOT connect the Scope yet 3 a your firmware is Easy steps to update the firmware to Double check your USB stick is working on the Rigol and the file is saved properly, seen at least one person bricked his scope due a bad downgrade of the firmware discussion here Check the MD5 sum of the DSEUpdate.
RGL file on your usb stick. Double check your USB stick is working on the Rigol and the file is saved properly, seen at least one person bricked his scope due a bad downgrade of the firmware discussion here check the MD5 sum of the DSEUpdate. The steps should be just the same as point 3c After the scope is on If Windows mentions that the "installed hardware does not function properly" then, disconnect the scope, reboot, connect the scope again. Start ultrascope, click on the little icon "connect" icon in the upper left corner right from the floppy to connect to the scope, in the left panel double click on "virtual console", click on "Run" under the "control" and play around to see if it works.
If it does then fine, exit the "virtual console" and then ultrascope and go to step 5. It might be also a good idea to stop and start the scope again - mine sometimes "hangs" when exiting ultrascope. If it does not work then there is a problem with the usb drivers or maybe you installed an old Ultrascope, in any case do not go further until Ultrascope works on this PC. The conditions are still the same, this will ONLY work on Wait until it ask you to restart your rigol and click OK.
Dont do anything in between, this might take a while.
