The instrument returns error messages in accordance with the SCPI standard.
l 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 GPIB, send
SYSTem:ERRor? from GPIB to read the error queue. Errors generated by instrument hardware are broadcast to all
I/O sessions.
l The instrument beeps each time an error is generated (unless disabled by SYSTem:BEEPer:STATe OFF). The front-
panel Error annunciator turns on when one or more errors are in the error queue.
l A special global error queue holds all power-on and hardware-related errors (for example, overtemperature).
l Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. When you have read all of the
interface-specific errors, the errors in the global error queue are retrieved. When you have read all errors from the
interface-specific and global error queues, the Error annunciator turns off.
l If more than 20 errors have occurred, the most recent error stored in the queue is replaced with -350,"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".
l The front panel reports errors from all I/O sessions and the global error queue. To read the error queue from the
front panel, press Help > View remote command error queue.
l Error conditions are also summarized in the Status Byte Register. For more information on the SCPI Status
System, see Status Subsystem Introduction.
l The interface-specific error queues are cleared by the *CLS (Clear Status) command and when power is cycled. All
errors are cleared when you read the error queue. The error queue is not cleared by a Factory Reset (*RST) or an
Instrument Preset (SYSTem:PRESet).
l Front Panel:
If the Error annunciator is on, there are errors in the error queue. The Remote annunciator is likely on as well.
Press the Local key to return to local operation (the Remote annunciator will go off). Then press [Help], select
"View remote command error queue" in the menu and press Select. Use the menu navigation "arrow" keys to
view the error messages. Press Back to exit and clear the error queue.
l SCPI:
SYSTem:ERRor? Read and clear one error from the queue
Errors have the following format (the error string may contain up to 80 characters):
