SIGLENT is the manufacturer and give very good service even if the Oscilloscope is branded with another name.
In my case I have one branded DIGITECH they have supplied me with *.ads firmware and *.cfg updates.
The *.cfg files are loaded into the SAVE/RECALL the updated .cfg file controled what was displayed on the screen plus band width, Rise times etc.
So as far as any firmware/software updates are needed you won't have any problems there.
ALL THE BEST
