Event Messages
Event messages read out in the MSG area in the bottom left of the display.
Event messages and message numbers are defined by the SCPI standard.
In the X-Series, sub-messages are often attached to add additional
information, to help the user better understand the event being reported. For
example, error –221 is defined as “Settings Conflict”, but in the X-Series you
will often see a longer message with error –221, such as “Settings Conflict;
Function not available in Zero Span”. This helps you understand exactly why
you are getting a Settings Conflict error.
