6.9.4 SCPI
SCPI (Standard Commands for Programmable Instruments) commands - messages -
are used for remote control. Commands that are not taken from the SCPI standard fol-
low the SCPI syntax rules. The instrument supports the SCPI version 1999. The SCPI
standard is based on standard IEEE 488.2 and aims at the standardization of device-
specific commands, error handling and the status registers. The tutorial "Automatic
Measurement Control" - A tutorial on SCPI and IEEE 488.2" from John M. Pieper (R&S
order number 0002.3536.00) offers detailed information on concepts and definitions of
SCPI.
The requirements that the SCPI standard places on command syntax, error handling
and configuration of the status registers are explained in detail in the following sec-
tions. For more information, see

6.9.5 VISA
VISA is a standardized software interface library providing input and output functions to

VISA, refer to its user documentation.
