Key
Local
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 the 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.

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:

TALKER/LISTENER
•
USE PASS CONTROL
•

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.
