Usually you'd get the vendor's programming guide for those SCPI
speaking devices. Then compare more recent models' capabilities
to the existing implementation, whether the same set of
instructions can be kept, or new instructions were introduced and
are required to use the newer device's features. Check the
vendor's download area for programming guides, or programming
related chapters in the user manual.

The specific question of what the supported_series[] table items'
fields mean -- just lookup the the item's data type declaration
(here: struct siglent_sds_series). Your diff's context (the
hunk's caption) shows it already. Get an editor that's capable of
navigating source code, if you don't have one yet. Otherwise
you'd be stuck with mere text search, which is possible but more
tedious.
