8.2 SCPI (standard commands for programmable instru-
ments)
SCPI commands - messages - are used for remote control. Commands that are not
taken from the SCPI standard follow the SCPI syntax rules. The R&S
ZNL/ZNLE sup-
ports 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 informa-
tion on concepts and definitions of SCPI.
Tables provide a fast overview of the bit assignment in the status registers. The tables
are supplemented by a comprehensive description of the status registers.
8.3 VISA libraries
VISA is a standardized software interface library providing input and output functions to
communicate with instruments. The I/O channel (LAN or TCP/IP etc.) is selected at ini-
tialization time by one of the following:
●
The channel–specific address string ("VISA resource string") indicated in Table 8-1
●
An appropriately defined VISA alias (short name).
A VISA installation is a prerequisite for remote control using the following interfaces:
●
Chapter 8.1.2, "GPIB interface (IEC 625/IEEE 418 bus interface)" , on page 152
●
Chapter 8.1.1, "LAN interface" , on page 148
For more information about VISA, refer to the user documentation.
