Device Selector - Agilent Technologies E5052A Programmer's Manual

Overview of Remote Control
GPIB Remote Control System
Required equipment
1. E5052A
2. External controller (computer)
Use a personal computer or workstation equipped with the GPIB interface. You need to
install software in the external controller to control this instrument via GPIB (for
example, HTBasic or Agilent VEE).
3. Other devices (other instruments and/or specific-purpose peripherals)
4. GPIB cables for connecting the E5052A, the external controller, and other devices
Size of system you can construct
• You can connect up to 15 devices in a single GPIB system.
• The length of cables connecting 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 shorter. You cannot construct a system with a total
cable length exceeding 20 m.
• The number of connectors connected to an individual device must be 4 or fewer. 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, which is used to identify devices on the same system. In the descriptions and
sample programs in this manual, it is assumed that the device selector is set to 717.
