:ERRor?
SYSTem:ERROR? returns the error messages in the error queue. See Appendix B
for a listing of possible error numbers and messages.
Comments •The Agilent E1446A places any generated errors into the error queue. The qu eu e
is first-in, first out. With several errors wa iting in the queue, the
SYSTem:ERRor? returns the oldest unread error me ssage first.
•The error queue can hold 30 error messages. If the Agilent E1446A generates
more than 30 messages that are not read, it rep laces the last error message in the
queue with error -350,"Too many errors". No additional messages are placed into
the queue until SYSTem:ERRor? reads some me ssages or the *CLS (clear status)
command clears the queue.
•When the error queue is empty, SYSTem:ERRor? returns + 0,"No error".
•Executable when initiated: Yes
