Errors
Error Message
•Errors are stored in a first in-first out (FIFO) order. The first error
message that is returned is the first error message that was stored.
When an error is read it is also cleared from the queue.
•If there are more than 10 errors produced the last error in the queue is
replaced with “Que overflow”. Unless the error queue is cleared, no
more errors can be written to the error queue. If there are no errors in
the error queue, the instrument will return “No error”.
•To clear the error queue, you can use the :SYSTem:CLEar command
or cycle the power. When you read a message from the error queue
that message will be cleared from the error queue. Using the *RST
command to reset the instrument does not clear the error queue.
•Remote control instructions can be used to clear the error queue. See
the instructions listed in the previous chapter for details.
