Common (*) Commands 6

*LRN (Learn Device Setup)
(see page 1610)
Query Syntax
*LRN?
The *LRN? query result contains the current state of the instrument. This query is
similar to the :SYSTem:SETup? (see page 1277) query, except that it contains
":SYST:SET " before the binary block data. The query result is a valid command
that can be used to restore instrument settings at a later time.
Return Format
<learn_string><NL>
<learn_string> ::= :SYST:SET <setup_data>
<setup_data> ::= binary block data in IEEE 488.2 # format
<learn string> specifies the current instrument setup. The block size is subject to
change with different firmware revisions.

• ":SYSTem:SETup" on page 1277
The *LRN? query return format has changed from previous Keysight oscilloscopes to match
the IEEE 488.2 specification which says that the query result must contain ":SYST:SET " before
the binary block data.
