The flashing power button is a feature of the power supply, not the firmware.
Professionals, especially the ones working in big research labs, dont like flashing lights, because these usually indicate something is wrong.
Consequently, Siglent changed this behavior for the SDS5000X at some point. As far as i know, the SDS2000X Plus has never been shipped with that feature - even though I still have one with a flashing power button, just because it's a pre-production unit. The new SDS6000A also doesn't have that, of course.
I did not know that Siglent changed it for the SDS1000 series as well - but if so, then it's only consequent.
Thanks for the clarification! (Although because of this statement I am rewarding you with the Spaßbremse of the Week Award because of smashing my hopes.
)
Do you think that even the slowly blinking would annoy the professionals? Maybe some components would be easy to change to solve my problem?
By the way, your in-depth review of the scope is amazing especialy for beginners, not sure if this kind of scope behaviour data is aviable for higher end scopes, or one has to measure himself every parameter.
My unit is hardware revision 01-05 (only about 2 months old, manufacture date in the last 6 months from memory) and there must be differences with the power supply as the power button does not flash in standby no matter what firmware version I use. (I've used 3 different versions during testing)
What temperature was the unit at ? I find with mine that standby power is higher when the unit is hot - eg just switched off after it has been running for a while, but after a while (maybe 15 minutes or so) the long-term standby power drops down to about 2 watts.
I wonder if people here are just taking a quick measurement and not leaving the unit to cool down and reach thermal equilibrium ?
Mesauring it right now. Until than: Regarding your scope being 6 month old, I wonder if Siglent is not affected at all by the chip shortage? So far everything seems to be aviable.
I would be also interested, if anyone opened the Hw version 01-05 and the other versions: Is there any difference in the powersupply? Are the Rubycon caps still there? I don't want to void the warranty on mine but maybe someone in the US where the laws are diferen could check this.
So far 4W, going to notify the forum if it changes.
