4.11.8 :SYSTem:ERRor[:NEXT]?
Syntax
:SYSTem:ERRor[:NEXT]?
Description
Queries and removes errors from the error queue.
Parameter
None.
Remarks
The power supply beeps once each time an error is detected. If more than 20 errors
have occurred, the last error stored in the queue (the most recent error) is replaced
with -350, “Queue overflow”. No additional errors are stored until you remove
errors from the queue.
Errors are retrieved in first-in-first-out (FIFO) order.
The error queue is cleared when power has been off or after
*CLS has been executed.
The
*RST command does not clear the error queue.
Return Format
The query returns the name and content of the error message, for example,
-113,"Undefined header; keyword cannot be found”. If no error has occurred, the
query returns 0,“No error”.
Examples
None.
4.11.9 :SYSTem:KLOCk:STATe

:SYSTem:KLOCk:STATe?
Command System
