The CoMmand parser Error bit (CME) is set true (1)
whenever a command syntax error is detected. The
CME bit has an associated CoMmand parser Register
(CMR) which specifies the error code. Refer to the
query CMR? for further details.

The EXecution Error bit (EXE) is set true (1) when a
command cannot be executed due to some device
condition (for example, the oscilloscope in local state)
or a semantic error. The EXE bit has an associated
Execution Error Register (EXR) that specifies the error
code. Refer to query EXR? for further details.
