Numeric Suffix
If a device features several functions or features of the same kind, e.g. inputs, the
desired function can be selected by a suffix added to the command. Entries without
suffix are interpreted like entries with the suffix 1. Optional keywords must be specified
if they select a function with the suffix.
Suffix counting
In case of remote control, suffix counting may differ from the numbers of the corre-
sponding selection used in manual operation. SCPI prescribes that suffix counting
starts with 1. Suffix 1 is the default state and used when no specific suffix is specified.
Some standards define a fixed numbering, starting with 0. With GSM, for instance,
slots are counted from 0 to 7. In the case of remote control, the slots are selected with
the suffixes 1 to 8. If the numbering differs in manual operation and remote control, it is
indicated with the respective command.
