B.104 SYSTem:ERRor? QUERY

Return Value:
Description: Posts error messages to the output queue. Returns the next error number followed by its corre-
sponding error message string from the instrument error queue. The error queue is a FIFO (first in first
out) buffer that stores errors as they occur. As it is read, each error is removed from the queue and the
next error message is made available. When all errors have been read, the query returns 0,"No error".
If more errors are accumulated than the queue can hold, it will overflow. The oldest errors stay in the
queue but the most recent errors are discarded. The last error in the queue will be -350,"Too many
errors." Error messages are defined in Table B-5.
