33 :SYSTem Commands

:SYSTem:ERRor

(see page 1610)

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> ::= an integer error code in NR1 format

<error string> ::= quoted ASCII string containing the error message

Error messages are listed in Chapter 40, “Error Messages,” starting on page 1549.
