where:
●
<vendor ID> is the vendor ID for Rohde & Schwarz (0x0AAD)
●
<product ID> is the product ID for the Rohde & Schwarz instrument
●
<serial number> is the individual serial number on the rear of the instrument

Example:
USB::0x0AAD::0x0016E::100001::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x0016E is the product ID for the R&S ESW44
100001 is the serial number of the particular instrument
14.1.2 SCPI (Standard Commands for Programmable Instruments)
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 ESW 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 reg-
isters. 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.
14.1.3 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, USB, ...) is selected
at initialization time by one of the following:
●
The channel–specific address string ("VISA resource string") indicated in
Table 14-1
●
An appropriately defined VISA alias (short name).
A VISA installation is a prerequisite for remote control using the following interfaces:
●
Chapter 14.1.1.2, "GPIB Interface (IEC 625/IEEE 418 Bus Interface)", on page 362
●
Chapter 14.1.1.1, "LAN Interface", on page 357
●
Chapter 14.1.1.3, "USB Interface", on page 364
