===488.2 commands===

Since SCPI was defined as an additional layer on top of the IEEE 488.2 specification, a SCPI compliant device should recognize various 488.2 commands too.<ref name="SCPI-1999-spec"/> These commands might also be known unofficially as asterisk commands (or star commands), because they all start with the [[asterisk]] <code>*</code> character.

According to section 4.1.1 of Volume 1 of SCPI, all SCPI devices must implement the following 488.2 commands.<ref name="SCPI-1999-spec"/> In the real world some low-end devicestest equipment may only support a subset of these 488.2 commands, or may even accept the commands but not perform any operation. A user should check the official programmers manual for each device before assuming all of these 488.2 commands are supported.
