When an interface is reset, it is changed to its power-on state. Before
an interface is re-activated, the relevant rear panel dip switch states
are scanned to determine the appropriate configuration.
Go to Local LCAL
Revert to local control of the instrument. This enables the front
panel key pad for instrument control. This command is only active
on telnet, raw-socket, and RS-232 connections. The other interfaces
have built in functionality for implementing this functionality.
Request Lock
LOCK?
Request the instrument lock. The SR474 returns 1 if the lock is granted
and 0 otherwise. When the lock is granted, no other instrument
interface may alter instrument settings until the lock is released via
the
UNLK
command or the power is cycled. It also forces a complete
lockout of the front panel.
Release Lock
UNLK?
Release a previously acquired instrument lock. Returns 1 if the lock
was released, otherwise 0. If
UNLK?
returns 0 and it is necessary
to verify that the instrument is not presently locked from any other
interface, acquire the lock with
LOCK? before executing the UNLK?
query.
Go to Remote REMT
Enable remote control of the instrument. In this mode, the front panel
key pad is disabled, so that control of the instrument can only occur
via the remote interface. This command is only active on telnet, raw
socket, and RS-232 connections. The other interfaces have built in
functionality for implementing this functionality.
