:SYSTem:ERRor
(see page 1428)
Query Syntax
:SYSTem:ERRor?
The :SYSTem:ERRor? query outputs the next error number and text from the error
queue. The instrument has an error queue that is 30 errors deep and operates on a
first-in, first-out basis. Repeatedly sending the :SYSTem:ERRor? query returns the
errors in the order that they occurred until the queue is empty. Any further queries
then return zero until another error occurs.
When remote logging is enabled (using the oscilloscope's front panel), additional
debug information can be included in the returned error string. If the error is
detected by the SCPI command parser, such as a header error or other syntax
error, the extra debug information is generated and included. But if the error is
detected by the oscilloscope system, such as when an out-of-range value is sent,
then no extra debug information is included.
Return Format
<error number>,<error string><NL>
<error number> ::= an integer error code in NR1 format
<error string> ::= quoted ASCII string containing the error message
Error messages are listed in Chapter 38, “Error Messages,” starting on page 1385.
