70 Keysight CXG, EXG, and MXG X-Series Signal Generators Programming Guide
Programming Examples
GPIB Programming Interface Examples
Local Lockout Function
The HP Basic function
LOCAL LOCKOUT
and the other listed IO library functions
disable the front panel keys including the Local key. With the Local key
disabled, only the controller (or a hard reset of line power) can restore local
control.
Local Function
The HP Basic function
LOCAL
and the other listed functions return the signal
generator to local control with a fully enabled front panel.
Library Function Statement Initialization Command
HP Basic The
LOCAL LOCKOUT
function disables all front-panel
signal generator keys. Return to local control can occur only
by cycling power on the instrument, when the
LOCAL
command is sent or if the
Preset
key is pressed.
10 LOCAL LOCKOUT
719
VISA Library The VISA library, at this time, does not have a similar
command.
N/A
NI-488.2 The
LOCAL LOCKOUT
function disables all front-panel
signal generator keys. Return to local control can occur only
by cycling power on the instrument, when the
LOCAL
command is sent or if the
Preset
key is pressed.
SetRWLS (parameter
list)
SICL The Keysight SICL igpibllo prevents 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.
igpibllo (id)
Library Function Statement Initialization Command
HP Basic The
LOCAL 719
function returns the signal generator to
manual operation, allowing access to the signal generator’s
front panel keys.
10 LOCAL 719
VISA Library The VISA library, at this time, does not have a similar
command.
N/A
NI-488.2 The NI-488.2 library function places the interface in local
mode and allows operation of the signal generator’s front
panel keys. The
ud
parameter in the parameter list is the
interface or device descriptor.
ibloc (int ud)
SICL The Keysight SICL function puts the signal generator into
Local operation; enabling front panel key operation. The
id
parameter identifies the session.
