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
Local
computer control.
