Thanks for the response! I'm a little more wary than yourself with firmware updates though, I've bricked several MBs in the past but thankfully no test gear (yet). I don't want to start now - .....
One struggles to imagine how you manage in this day and age.
Really, the risk is soooo low if the instructions are followed to the letter.
I've seen some members mention using a UPS so that even power loss is removed as a risk.
Do you not do any updates of modern gear ?
I've only done one MB bios flash but that was many years ago.
Anything else I own I check for updates on a irregular basis.
There has been talk behind the scenes of Siglent enabling some equipment to connect directly to their server (after user input) and installing updates automatically with user confirmation to do so.
Would this ability give you more confidence to update firmware in equipment ?
It's not the fallback to using the internal reference per se because I would expect it to do that if there were no external ref signal present. It's the fact that it does so when re-booted with the external ref active and it still erroniously reports it is using the external ref whilst actually it is using the internal reference. It can be difficult to actually diagnose it is doing this without performing some tests so I routinely need to remember to reset to internal ref, then change it back to external again in the settings.
As indicated in replies from Siglent this behaviour
will be changed and in
all SDG AWG models that support EXT frequency reference. The proposal is OSD indication of the REF source and manual selection only to protect any EXT source from possible damage.
