Setting up the Equipment for Remote Operation
The signal generator can be remotely controlled using either the general purpose interface
bus (GPIB) or a serial connection to the rear-panel RS-232 auxiliary interface connector.
GPIB Overview
GPIB is a high-performance bus that allows individual instruments and computers to be
combined into integrated test systems. The bus and its associated interface operations are
defined by the IEEE 488.1 standard. The IEEE 488.2 standard defines the interface
capabilities of instruments and controllers in a measurement system, including some
frequently used commands.
NOTE The functionality provided by GPIB is also available using the rear-panel
RS-232 AUXILIARY INTERFACE. For more information on using this type of
system configuration, see “Serial Interface (RS–232) Overview” on page 1-7.
Commands are sent over the GPIB via a controller’s language system. HP BASIC is the
language used in the programming examples in this book. HP BASIC was selected because
the majority of GPIB computers have BASIC language capability. However, other
languages can also be used. The use of HP BASIC is explained later in this chapter
starting with “Programming the Signal Generator” on page 1-9.
Additional Required Equipment
The following tables list the additional required equipment to implement an GPIB system
interface between a computer or workstation and the signal generator.
