GPIB Interface
Информация
The GPIB Interface section consists of the SEC-1065 (Serial
Control) and SER-1066 (Serial Register) modules. These
modules provide the necessary hardware and control logic to
remotely program an instrument via the GPIB (General Purpose
Interface Bus) in accordance with the ANSI/IEEE Std 488.1-1987.
The SEC and SER modules are unique and may not be
interchanged with any other modules in the instrument. The
two modules are piggy-backed and interconnected through a
connector. Together, the boards are mechanically fastened to
the instrument rear panel by four screws. The SEC module
faces to the rear and contains a standard 24-pin GPIB
connector and a six-position DIP switch for address and
listen-mode selection. The SER module connects internally to
the rest of the instrument through two header strips: one
for frequency and amplitude control, and a second for phase
rotation control.
Functional Overview
The basic data transfer on the GPIB is bit parallel, byte
serial (one byte at a time), under the direction of a GPIB
controller. The user typically provides the controller with
information on the address of an instrument to be
controlled, and any instrument-specific (also called
devicedependent) instructions. The controller (or control
program) will then generate a string of characters
containing the ASCII codes for addressing the instrument and
performing the instrument-specific function, and transmit
these in conformance with the IEEE 488 timing and
handshaking specifications.
A PTS Synthesizer equipped with the GPIB Interface acts as a
basic listener device. The standard LISTEN ONLY and
ADDRESSED modes of operation are supported. In the LISTEN
ONLY mode, all valid commands are accepted without regard to
device address; in the ADDRESSED mode, only commands
preceded by the instrument's selectable address are executed.
In addition to LOCAL/REMOTE mode control, PTS's GPIB
Interface has the capability to perform three
synthesizer-specific (or device-dependent) functions through
appropriate commands issued over the GPIB: setting the
output frequency, setting the output signal level, and
setting phase rotation (for instruments equipped with a
phase-rotation option).
