When the error queue is not empty the error queue bit in the Status
register will be set.
Querying For the Errors
Command:
[:]SYSTem:ERRor[:EVENt]?
5-54
The error/event queue contains items that include a numerical and
textual description of the error or event. Querying for the full
queue item (for example, with SYSTem: ERRor [ :NEXT] ?) will
return a response with the following syntax:
The <Error/event_number> is a unique integer in the range
[-32768, 32767]. All positive numbers are instrument-dependent.
All negative numbers are reserved by the SCPI standard with
certain standard error/ event codes described in the SCPI 1999
standard document. The value, zero, is also reserved to indicate
that no error or event has occurred.
The second parameter of the full response is a quoted string
containing an <Error/event_description> followed by optional
<Device-dependent info> text. Each <Error/event_number> has a
unique and fixed <Error/ event_description> associated with it.
The maximum string length of <Error/event_description> plus
<Device-dependent_info> is 255 characters.
As errors and events are detected, they are placed in a queue. This
queue is first in, first out. If the queue overflows, the last
error/event in the queue is replaced with error:
Any time the queue overflows, the least recent errors/events
remain in the queue, and the most recent error/event is discarded.
The error queue implemented in the XG/XTR is capable of holding
4 errors.
Executing a query of the event queue will respond with the oldest
error currently on the queue. This error is removed. The response
format is discussed in the error/event queue description section.
