Remote Operation
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 SR470 returns 1 if the lock is
granted and 0 otherwise. When the lock is granted, no other instru-
ment interface may alter instrument settings until the lock is released
via the
UNLK
command or the power is cycled. It also forces a com-
plete 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.

LF
’, i.e., ASCII character 13,
followed by ASCII character 10. The interface terminator may be set
to a di
ff
erent sequence of up to three characters in length by executing
XTRM
with parameters that consist of the decimal equivalent of the
ASCII characters desired, separated by commas.
XTRM 65,66,13
