Basics
SCPI Programmers Manual
If the LAN is supported by a DNS server, the host name can be used instead of the IP address.
The DNS server (Domain Name System server) translates the host name to the IP address. The
resource string has the form:
TCPIP::‹host_name›::‹IP_port›::INSTR
1.1.4 GPIB Interface (IEC/IEEE Bus Interface)
An optional GPIB interface is also available for the HMF series. This solution is particularly attrac-
tive for customers who already have an existing GPIB environment. With minimum efforts, an
old instrument can be replaced by a model of the HMF series.
To be able to control the instrument via the GPIB bus, the instrument and the controller must be
linked by a GPIB bus cable. A GPIB bus card, the card drivers and the program libraries for the
programming language must be provided by the controller. The controller addresses the instru-
ment with the GPIB instrument address.
Characteristics
The GPIB interface is described by the following characteristics:
•
Up to 15 instruments can be connected
•
The total cable length is restricted to a maximum of 15m; the cable length between two
instruments should not exceed 2m.
•
A wired „OR“-connection is used if several instruments are connected in parallel.
GPIB Instrument Address
In order to operate the instrument via remote control, it must be addressed using the GPIB
address. The remote control address is factory-set to 20, but it can be changed in the network
environment settings or in the HMF MENU under INTERFACE -> PARAMETER. For remote
control, a GPIB address from 0 to 30 are allowed. The GPIB address is maintained after a reset of
the instrument settings.
1.2 Setting Up a Network (LAN) Connection
1.2.1 Connecting the Instrument to the Network
NOTICE
Risk of network failure
Before connecting the instrument to the network or configuring the network, consult
your network administrator. Errors may affect the entire network.
The network card can be operated with a 10 Mbps Ethernet IEEE 802.3 or a 100 Mbps Ethernet
IEEE 802.3u interface.
