INTRODUCTION
The 2040 series Signal Generators can be operated remotely from a personal computer
fitted
with
a GPIB interface card or a dedicated
GPIB controller. All functions can be controlled
by coded messages sent over
the interface bus via the 24 way socket on the rear panel of the
instrument. IEEE Standard
488.2
(1987)
is implemented, which
defines the protocols
and syntax
of commands.
The instrument can
function either as a talker or a listener. In the listen mode, it will
respond to IEEE 488.2 common commands and queries and device-specific commands
and
queries. These allow various device
functions to be controlled and operating parameters to be set.
In the talk mode,
device
status information and parameter settings can be read from the
instrument.
For full information on the IEEE protocols and
syntax
the
IEEE 488.2 Standard should
be consulted.
