Remarks
The instrument beeps once each time a command syntax or hardware
error is generated. The front-panel ERROR annunciator turns on when one
or more errors are currently stored in the error queue.
Errors are retrieved in first-in-first-out (FIFO) order. The first error
returned is the first error that was stored.
Errors are cleared as you read them. When you have read all errors from
the error queue, the ERROR annunciator turns off.
If more than 20 errors have occurred, the last error stored in the queue
(the most recent error) is replaced with -350,"Error queue overflow".
No additional errors are stored until you remove errors from the queue. If
no errors have occurred when you read the error queue, the instrument
responds with +0,"No error".
Errors generated by the instrument hardware are broadcast to all I/O
sessions.
The front panel reports errors from all I/O sessions and clears them. To
read the error queue from the front panel, use the Utility menu (press the
[Utility] key). See the Agilent 34410A/11A/L4411A User's Guide for
further information.
Error conditions are also summarized in the Status Byte Register. For
more information on the SCPI Status System for the
Agilent 34410A/11A/L4411A, see Status System Introduction.
The error queue is cleared by the *CLS (Clear Status) command (for the
I/O session), and when power is cycled (for all errors). All errors are
cleared when you read the error queue. However, the error queue is not
cleared by a Factory Reset (*RST command) or an Instrument Preset
(SYSTem:PRESet command).
