GPIB OPERATION
3-2-2
INTRODUCTION
The NAV-750C signal generator 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.
