ERRor?

SYSTem:ERROR? returns the error messages in the error queue. See Appendix B for a listing of the digitizer error numbers and messages.

Comments ∙ As errors are detected, they are placed in the error queue. The queue is first-in, first out, meaning that if several error messages are waiting in the queue, SYSTem:ERRor? returns the oldest unread error message.

∙The error queue can hold 30 error messages. If more than 30 messages are generated without being read, the last error message in the queue is replaced with error -350,"Too many errors". No additional messages are placed into the queue until SYSTem:ERRor? reads some messages or until the queue is cleared using the *CLS (clear status) command.

∙When the error queue is empty, SYSTem:ERRor? returns +0,"No error".

∙*RST Condition: unaffected

∙Power-On Condition: no errors are in the error queue
