6.1 Remote Control - Fundamentals
6.1.1 Introduction - Remote Control Fundamentals
In this chapter you will find:
●
instructions on starting the Audio Analyzer R&S UPP by remote control,
●
a general introduction to the remote control of programmable instruments, includ-
ing details of command structure and syntax, command processing and the status
registers,
●
a graphic and tabular presentation of the status registers used in the Audio Ana-
lyzer R&S
UPP,
The remote control commands of the Audio Analyzer R&S UPP are included in Chap-
ter 5, "Instrument functions," and Chapter 7, "Remote control - commands."
To standard the instrument comes with the following interfaces for remote control:
●
IEC/IEEE bus interface in line with the IEC 625.1/IEEE 488.2 standard.
●
LAN interface; the network card uses 100 MHz Ethernet IEEE 802.3u; the protocol
is based on the VXI-11 standard.
●
USB interface (device USB)
A controller can be connected on the remote control interfaces, either direct via IEC-
bus, USB interface or through a network (LAN). The connectors are located on the rear
panel of the instrument.
Remote control via IEC/IEEE bus and USB interface are identical concerning the
requirements. The differences to remote control via LAN are minor, they will be descri-
bed in greater detail below. If remote control via IEC/IEEE bus is described below it
also includes remote control via the USB interface!
These connectors are detailed in Chapter 9, "Maintenance and Instrument Interfaces" ,
on page 878.
SCPI commands (messages) are used for remote control. Commands not derived from
the standard nevertheless follow SCPI syntax rules. The instrument supports SCPI ver-
sion 1999 (Standard Commands for Programmable Instruments). The SCPI standard
sets up on the IEEE 488.2 standard, and aims at standardization of device-specific
commands, error handling and status registers. For more information on the SCPI con-
cept and definitions, refer to the book "Automatic Measurement Control – A tutorial on
SCPI and IEEE 488.2" by John M. Pieper, R&S ordering number 0002.3536.00.
