LOCk
Enables or disables all front-panel buttons and knobs. There is no front panel
equivalent.
When the front panel is locked, neither theFPAnel:PRESS nor the FPAnel:TURN
commands will work. They will not generate an error event either. You can work
around this by using the appropriate programmatic interface commands, instead of
the front-panel commands. For example, to set the trigger level to 50%, you could
use TRIGger:A SETLevel. To force a trigger, you could use TRIGger FORCe.

Returns the commands that list the oscilloscope settings except for configuration
information for the calibration values, the WFMInpre? query, and the
WFMOutpre? query. This query allows you to record or "learn" the current
oscilloscope settings. You can use these commands to return the oscilloscope to
the state it was in when you made the *LRN? query. This command is identical
to the SET? Command.
