7 Network Operation and Remote Control
This chapter provides basic information on operating an instrument via remote control.
For additional information on remote control basics, and the SCPI command structure,
see Chapter A, "Additional Basics on Remote Control", on page 81.
7.1 Remote Control Interfaces
The R&S HMP Series provides the following interfaces for remote control:
●
Ethernet (LAN) / USB Dual Interface (standard HO732)
●
RS-232 / USB Dual Interface (optional HO720)
●
IEE-488 (GPIB) Interface (optional HO740)
The optional interfaces replace the Ethernet / USB HO732 interface module on the rear
panel.
For information on the pin assignment of the interface connectors, see Chapter B,
"Hardware Interfaces", on page 91.
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 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 reg-
isters. The tutorial "Automatic Measurement Control - A tutorial on SCPI and IEEE
488.2" from John M. Pieper (Rohde & Schwarz order number 0002.3536.00) offers
detailed information 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, see Chap-
ter A.3, "Status Reporting System", on page 86.

7.1.1
Ethernet / USB Dual Interface R&S HO732
To be integrated in a LAN, the instrument is equipped with a LAN interface, consisting
of a connector, a network interface card and protocols.
For remote control via a network, the PC and the instrument must be connected via the
LAN interface to a common network with TCP/IP network protocol. The TCP/IP net-
work protocol and the associated network services are preconfigured on the instru-
ment.
