Got my SDS5034 yesterday. As expected, the 1GHz options works but doesn't provide the full bandwidth. But that's OK with me. It's a 5GSa/s scope anyway, so aren't too many sample points in the high time resolutions.
For what it's worth, I measured a mean rise time of around 550ps (140mV/div, Sinc, 1ns/div). So I guess there isn't much of a difference between different models.
Calibration certificate is dated 4/2020.
Side note: my scope came with all options installed (bought it just at the end of the promotion) but it still came with an option card for the function generator and obviously Welectron wants to deliver option cards for the remaining 6 licenses. I still tried the "authorized" code on the option card on the siglent website but that resulted in "The Authorized code is invalidated".
So I just wonder: is it normal that the options come pre-installed for scopes bought during the "all options" promotion? Did you guys get any option cards of other proof about owning these options?
