SCPI Error Messages

The Agilent 34410A/11A/L4411A returns error messages in accord with the
SCPI standard.
A record of up to 20 errors can be stored in the instrument's error queue.
Each remote interface I/O session (GPIB, USB, VXI-11, Telnet/Sockets)
has its own interface-specific error queue. Errors appear in the error queue
of the I/O session that caused the error. For example, if an error was
generated by a command sent over the GPIB interface, send the command
from GPIB to read the error queue.
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.
A special global error queue holds all power-on and hardware-related
errors (for example, over-temperature).
Errors are retrieved in first-in-first-out (FIFO) order. The first error
returned is the first error that was stored. Once you have read all of the
interface-specific errors, the errors in the global error queue are retrieved.
Errors are cleared as you read them. When you have read all errors from
the interface-specific and global error queues, the ERROR annunciator
turns off and the errors are cleared.
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".
The front panel reports errors from all I/O sessions as well as the global
error queue. To read the error queue from the front panel, press [Shift] +
[Data Log] (Utility), and then select "SCPI Errors" in the utility menu.
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 Subsystem Introduction.
The interface-specific error queues are cleared by the *CLS (Clear Status)
