Yes, no LAN but I DO have an RS-232 port... The NI VISA driver (2023 Q3 version), which I installed yesterday on the Win10 side, required almost 1.5 hours to set up. Elapsed time involved uninstall of the NI software and then re-installation of the newer version. And I skipped all the optional installs offered. Not for the impatient.
As for SNAP, it appears that a reboot was necessary after installing SNAP-STORE, as today Evolution seems to know which way the wind blows once again. Following on-line installation advice, I had already rebooted twice after installing the daemon, snapd. I need to understand this application better, and anyway we're getting off thread here. Enough said.
I will also investigate whether NI has any tools, e.g. drivers, for Linux.
Thanks once again to all for their support.

As a followup edit: lsusb shows the presence of the Siglent scope, but Dolphin file manager does not show the device as part of the system. This probably means no driver is recognized and installed automatically. More details on the Siglent USB parameters are (would have attached this but didn't know how) :
