• E5071C
• External controller (PC or workstation that can be connected to LAN
and Agilent I/O Library is installed into)
• Other devices (other instruments and/or peripherals that serve your
purpose)
• GPIB cables
Scale of system you can construct
• You can connect up to 15 devices in a single GPIB system.
• The length of cables to connect between devices must be 4 m or
less. The total length of connecting cables in a single GPIB system
must be 2 m × the number of connected devices (including the
controller) or less. You cannot construct the system in which the
total cable length exceeds 20 m.
• The number of connectors connected to an individual device must be
4 or less. If you connect 5 or more connectors, excessive force is
applied to the connector part, which may result in failure.
• You can choose the device connection topology from star, linear, and
combined. Loop connection is not supported.
Device selector
The device selector is a unique value assigned to each device that is used
by the controller to select the control target (to send/receive messages)
among devices connected on the GPIB remote control system.
The device selector consists of a select code (usually, 7) and a GPIB
address. For example, when the select code is 7 and the GPIB address is
17, the device selector is 717. The select code must be set for each
system. The GPIB address must be set to a unique value for each device,
