Error Messages
Error messages are created once an erroneous condition is detected.
Errors are retrieved in first- in- first- out (FIFO) order using the
SYSTem:ERRor?
query or read from the front panel (see “Reading error
messages” in the U3606A User’s and Service Guide ).
The first error returned is the first error that was stored. Reading this
error will clear this error allowing the next stored error to be read (if
there are other errors stored). Once you have read all of the
interface- specific errors, the errors in the global error queue will be
retrieved.
If more than 20 errors have occurred, the last error stored in the queue
(the most recent error) is replaced with error number:
–350,"Queue overflow"
. No additional errors are stored until you
remove the previously stored errors from the queue.
If no errors have occurred when you read the error queue, the instrument
responds with the message:
+0,"No error"
or “nonE” if read from the
front panel.
The interface- specific and global error queues are cleared by the clear
status (
*CLS
) command and when the instrument power is cycled. The
error queue will not be cleared by a Factory Reset (
*RST
command) or an
Instrument Preset (
SYSTem:PRESet
command).
