Lock ¶

The LOCk command.

Description

This command enables or disables the touch screen and all front panel buttons and knobs. There is no front panel equivalent. When the front panel is locked, the front panel commands will not work and will not generate error events. You can work around a locked front panel, 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.

Usage

Using the .query() method will send the LOCk? query.
Using the .verify(value) method will send the LOCk? query and raise an AssertionError if the returned value does not match value.
Using the .write(value) method will send the LOCk value command.
