Getting Started
Using GPIB
Agilent BASIC The REMOTE 719 function disables the front panel operation of all keys with the
exception of the
Local key.
VISA Library The VISA library, at this time, does not have a similar command.
NI-488.2
Library This NI-488.2 library function asserts the Remote Enable (REN) GPIB line. All devices
listed in the parameter list are put into a listen-active state although no indication is
generated by the signal generator. The parameter list describes the interface or device
descriptor.
SICL The Agilent SICL function puts an instrument, identified by the id parameter, into
remote mode and disables the front panel keys. Pressing the
Local key on the signal
generator front panel restores manual operation. The parameter id is the session
identifier.
Local Lockout Function
The Agilent BASIC function LOCAL LOCKOUT and the other listed IO library functions can be used to
disable the front panel keys including the
Local key. With the Local key disabled, only the controller (or a
hard reset of the line power switch) can restore local control.
Agilent BASIC The LOCAL LOCKOUT function disables all front-panel signal generator keys. Return to
local control can occur only with a hard on/off, when the LOCAL command is sent or if
the
Preset key is pressed.
VISA Library The VISA library, at this time, does not have a similar command.
NI-488.2
Library The NI-488.2 library function places the instrument described in the parameter list in
remote mode by asserting the Remote Enable (REN) GPIB line. The lockout state is
then set using the Local Lockout (LLO) GPIB message. Local control can be restored
only with the EnableLocal NI-488.2 routine or hard reset. The parameter list describes
the interface or device descriptor.
SICL The Agilent SICL igpibllo function prevents user access to front panel keys operation.
The function puts an instrument, identified by the id parameter, into remote mode with
local lockout. The parameter id is the session identifier and instrument address list.
