from controller commands. Settings are unaffected by transitions among the 4 remote-local states. The REMOTE
indicator lights when the waveform generator is in REMS or RWLS.
Local State (LOCS)
When in a local state (LOCS), you control the settings through the front-panel controls. In addition, only GPIB
query commands are executed. All other GPIB commands setting and operational prompt and error since those
commands are under front-panel (local) control.
NOTE
The waveform generator can be in either Local State (LOCS) or Remote State (REMS) when the it receives the
Local Lockout (LLO) interface message. If in LOCS and REN is asserted, the waveform generator enters the
Local With Lockout State (LWLS) or, if in REMS, it enters the Remote With Lockout State (RWLS) when it
receives LLO. The controller controls the LWLS and RWLS state transitions.
Local Without Lockout State (LWLS)
When the waveform generator is in a local without lockout state (LWLS), it operates the same as it does in LOCS.
However, in LWLS rtl does not inhibit a transition to remote state.
Remote State (REMS)
When the waveform generator is in a remote state (REMS), you control its operations from the controller. All
settings update when GPIB are executed.
Remote With Lockout State (RWLS)
When in a remote with lockout state (RWLS), the waveform generator operates much the same as it does in
LOCS. However, when in RWLS the waveform generator ignores the rtl message, locking out any changes made
from the front panel.
4.17.3 IEEE 488.2 Interface Function Subsets
IEEE Standard 488.2 identifies the interface function repertoire of a device on the bus in terms of interface
function subsets. These subsets are defined in the standard. Table C-1 lists the subsets that apply to the waveform
generator.

Electronics Engineers, Inc., 345 East 47 Street, New York, New York 10017.
