SYSTem:ERRor?
This query returns error numbers and messages from the U8480 Series error
queue. When an error is generated by the U8480 Series, it stores an error number
and corresponding message in the error queue. One error is removed from the
error queue each time this query is executed. The errors are cleared in the order of
first-in first-out, which means that the oldest errors are cleared out first. To clear
all the errors from the error queue, execute the *CLS command. When the error
queue is empty, subsequent SYSTem:ERRor? queries return a +0, “No error”
message. The error queue has a maximum capacity of 50 errors.
Syntax
Example
Error queue messages have the following format:
For example, –330, “Self-test Failed;ROM Check Failed”
Errors are retrieved in a first-in first-out (FIFO) order. If more than 50 errors occur,
the error queue overflows and the last error in the queue is replaced with the error
–350, “Queue overflow”. Each time the queue overflows, the most recent error is
discarded.
