GPIB Operation
GPIB Operation This section contains information on the following topics:
• local key
• GPIB controller modes
• instrument addresses
• using the parallel port
Key
This key is allows you to return the analyzer to local (front panel) operation from remote
(computer controlled) operation. This key will also abort a test sequence or hardcopy
print/plot. In this local mode, with a controller still connected on GPIB , you can operate th e
analyzer manually (locally) from the front panel. This is the only front panel key that is
not disabled when the analyzer is remotely controlled over GPIB by a computer. The
exception to this is when local lockout is in effect: this is a remote command that disables
the key, making it difficult to interfere with the analyzer while it is under
computer control.
In addition, the key accesses the GPIB menu, where you can set the controller
mode, and to the address menu, where you can enter the GPIB addresses of peripheral
devices and select plotter/printer ports. You can also set the mode of the parallel port here.
The GPIB menu consists of the following softkeys:

The analyzer is factory-equipped with a remote programming interface using the General
Purpose Interface Bus (GPIB). This enables communication between the analyzer and a
controlling computer as well as other peripheral devices. This menu indicates the present
GPIB controller mode of the analyzer. Three GPIB modes are possible: system controller,
talker/listener, and pass control.
