I just upgraded to R12 firmware, but when I connect via SCPI and issue :syst:board? my scope locks up, TCP/IP connection is lost, UI frozen and needs a hard power off to restart.
*IDN? works fine, gives Siglent Technologies,SDS2504X Plus,SDS2PDDQ5R2444,5.0.1.3.9R12.
Any thoughts? I am using Keysight Interactive IO for the SCPI commands.
