While IEEE 488.1 defined the hardware and IEEE 488.2 defined the protocol, there was still no standard for instrument-specific commands. Commands to control the same class of instrument, e.g., multimeters, would vary between manufacturers and even models.
The United States Air Force,[4] and later Hewlett-Packard, recognized this problem. In 1989, HP developed their TML language[5] which was the forerunner to Standard Commands for Programmable Instrumentation (SCPI). SCPI was introduced as an industry standard in 1990.[6] SCPI added standard generic commands, and a series of instrument classes with corresponding class-specific commands. SCPI mandated the IEEE 488.2 syntax, but allowed other (non-IEEE 488.1) physical transports.
The Hp8510C did not support IEEE 488.2 or SCPI, but did support 488.1 GPIB and defined its own set of commands.
Don't go there. several instrument mfgs have claimed compliance to IEEE488.1 There is no such thing! 488, 488.2 Other than that mfgs have tried to bamboozle you! 488.1 is like RS-232. Dou you know what the "RS" is short for? (Recommended Standard)
point to a definition of IEEE488-1 (its SCPI wannabe) Then RTM for the 6603B and understand the SYStem:LANGuage command <SCPI|HPPSL>
