Hi, I have a SDS-1104X-E and I'm very happy with it.
My software version is the original 7.6.1.12R1, do you advice to update even if I don't have significant problems with it?
What is the correct procedure? I have to update the OS and the firmware togheter?
Even if you have not noticed any significant problems yet, there are still lots of issues that have been addressed since the original V7.6.1.12 firmware. Traditionally, there are always significantly more fixes and improvements than what is listed in the version history. So my advice can only be to keep the firmware of your DSO up to date, even if you don't see an immediate need for that.
As for the correct procedure, it's basically straight forward. The OS update is independent from the firmware, so you can update both components in any order you like. I have updated the OS first, which happens so quick by the way that I wasn't even sure if it actually worked. Then the update of the firmware, where the additional version number field "7.
1.6.1.25R1" finally confirmed that everything woked as expected.
Both updates are fairly easy to do:
OS update: just copy the 4 files (everything in the package short of the two version history files) to an empty 8GB or 32GB*) USB stick. Turn off the DSO, insert the USB stick, turn the scope on. After the startup is completed (which hardly takes any longer than usual), the update is already done.
Then copy the firmware update file *.ADS to the USB stick, plug it back in the DSO, choose UTILITY/UPDATE/Firmware, navigate to the *.ADS file using the universal control, then press the "Press To Update" softkey. Then restart the scope (using the power button) when prompted to do so and check the UTILITY/System Status to confirm the firmware version number is 7.1.6.1.25R1 as expected. Finally perform a self-calibration after the DSO has been up and running for at least 30 minutes (in total) and you're done.
*) This is what Siglent states in the update instructions. But actually any USB stick should work just fine, as long as it is FAT16 or FAT32 formatted.
