SYSTem:ERRor[:NEXT]?
This query returns the next error number and its corresponding error message
from the error queue. When an error is generated by the 8990B, it stores an error
number and its corresponding message in the error queue. One error is removed
from the error queue each time this query is sent. The errors are cleared in the
first-in first-out (FIFO) order, where the oldest errors are cleared first. When the
error queue is empty, subsequent
SYSTem:ERRor?
queries will return 0,“No
error”.
