Appendix A: Error Messages
Any errors that occur during operation from either the front panel or the remote control interface
will result in error messages. Error messages are displayed on the LCD display. They are also
stored in the error message queue from which they can be queried using the SYST:ERR? Query.
The error queue has a finite depth. If more error messages are generated than can be held in the
queue, a queue overflow message will be put in the last queue location. To empty the queue, use
the error query until the No Error result is received.
Errors appearing on the LCD will generally remain visible until the user moves to another screen.
If multiple error messages are generated in succession, only the last message will be visible as
there is only space for one error message on the LCD display.
The same area of the display is also used to display status messages. While error messages
always have a negative error number, status messages have a positive number.
The table below displays a list of possible error and status messages along with their possible
cause and remedy.
