16. 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 (Error –400, “Queue Overflow) will be put in the last queue location. To
empty the queue, use the system error query until a 0, “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.
The table below displays a list of possible error and status messages along with their possible cause
and remedy.
