:MARKer:X1Y1source
(see page 786 )
Command Syntax
:MARKer:X1Y1source <source>
<source> ::= {CHANnel<n> | FUNCtion | MATH}
<n> ::= {1 | 2 | 3 | 4} for the four channel oscilloscope models
<n> ::= {1 | 2} for the two channel oscilloscope models
The :MARKer:X1Y1source command sets the source for the cursors. The
channel you specify must be enabled for cursors to be displayed. If the
channel or function is not on, an error message is issued.
If the marker mode is not currently WAVeform (see ":MARKer:MODE" on
page 297):
• Sending a :MARKer:X1Y1source command will put the cursors in the
MANual mode.
• Setting the source for one pair of markers (for example, X1Y1) sets the
source for the other (for example, X2Y2).
If the marker mode is currently WAVeform, the X1Y1 source can be set
separate from the X2Y2 source.
If :MARKer:MODE is set to OFF or MANual, setting :MEASure:SOURce to
CHANnel<n>, FUNCtion, or MATH will also set :MARKer:X1Y1source and
:MARKer:X2Y2source to this value.
Query Syntax
:MARKer:X1Y1source?
The :MARKer:X1Y1source? query returns the current source for the
cursors. If all channels are off or if :MARKer:MODE is set to OFF, the
query returns NONE.
Return Format
<source><NL>
<source> ::= {CHAN<n> | FUNC | NONE}

N O T E
MATH is an alias for FUNCtion. The query will return FUNC if the source is FUNCtion or
MATH.
