SCPI Error Messages
Command Errors(-100...) | Execution Errors (-200..) | Device-Specific Errors (-300...) | Query Errors (-
400...) |

The Keysight 53220A/230A return error messages in accord with the SCPI standard.
l A record of up to 20 errors can be stored in the instrument's error queue. Each remote interface I/O ses-
sion (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.
l 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.
l A special global error queue holds all power-on and hardware-related errors (for example, over-tem-
perature).
l 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.
l 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.
l 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".
l 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 the Help key, and then select "View remote command error queue" in
the utility menu.
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 command) or an Instrument Preset (SYSTem:PRESet command).
l Front-Panel Operation:
If the ERR annunciator is on, there are errors in the error queue. The REM annunciator is likely on as
well. Press the Back (Local) key to return the instrument to local operation (the REM annunciator
will go off). Then press the Help key, 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 Remote Interface Operation:
SYSTem:ERRor? Read and clear one error from the queue
Errors have the following format (the error string may contain up to 255 characters):
-113,"Undefined header"
