5730A
Operators Manual
Local-to-Remote State Transitions
The 5730A Calibrator can be operated either locally from the front panel, or remotely
with remote control commands. In addition to front panel and remote control operation,
the controller can be placed in a local lockout condition at any time by remote command.
When combined, the local, remote, and lockout conditions yield four possible operating
states:
•
•
•
6-48
Local (Front-Panel Operation)
The Calibrator responds to local and remote commands, but only remote
commands that do not affect the state of the Calibrator are allowed to execute.
For example, OUT? returns the value of the Calibrator output setting and is
executable in the local state. OUT sets the output to another value but cannot be
executed in local state.
Local with Lockout
Local with lockout is identical to local, except the Calibrator will go into the
remote with lockout state instead of the remote state when it receives a remote
command. The local with lockout state is entered by executing the LOCKOUT
statement from an IEEE-488 controller, or by sending the LOCKOUT command
from a RS-232C/UCB/Ethernet controller.
Remote
When the Remote Enable (REN) line is asserted and the controller addresses the
Calibrator as a listener, it enters the remote state. These conditions are met, for
example, when a GPIB controller executes the statement "OUT 10 V,
1khz;OPER". In the remote state, display changes to:

Front panel operation is restricted to use of the power switch and the Local
Control selection. Touch Local Control or send the GTL (Go To Local)
interface message to return the Calibrator to the local state. (One way to send the
GTL interface message in some controllers is by executing the LOCAL
statement.)
