SCPI Error Messages

Execution Errors (-101...) | Instrument Errors (100...) | Self-Test Errors (600...) | Calibration Errors (700–749) | Firmware Update Errors (791...) | Plug-In Module Errors (900...)

• A record of up to 20 errors can be stored in the instrument's error queue. Each remote interface I/O session (i.e., GPIB, USB, LAN, etc.) 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 this 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 (e.g., over-temperature, Safety Interlock, etc.).

• 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, use the View key.

• Error conditions are also summarized in the Status Byte Register. For more information on the SCPI Status System for the Agilent 34980A, see Status System Introduction.

• The interface-specific and global error queues are cleared by the *CLS (Clear Status) command and when power is cycled. The errors are also 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).

• Front-Panel Operation:
  If the ERROR annunciator is on, press [View] to view the errors. Use the knob to scroll through the error numbers. Press [>] to view the text of the error message. Press [>] again to increase the scrolling speed (the final key press cancels the scroll). All errors are cleared when you exit the menu.

• 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 80 characters):
  
  -113,"Undefined header"
