LOCkEnables or disables all front-panel buttons and knobs. There is no front panel
equivalent.
When the front panel is locked, neither theFPAnel:PRESSnor 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.
