23 Marker Commands
:MARKer:VSTOp
Command :MARKer:VSTOp <By_position>
The :MARKer:VSTOp command sets the By marker position. The
:MARKer:Y2Position command described in this chapter also sets the
By marker position.
<By_position> A real number for the time at the By marker, in seconds.
Example This example sets the By marker at 10 mV. Notice that this example uses
the Y2Position command instead of VSTOp.
myScope.WriteString ":MARKER:Y2POSITION 10E-3"
Query :MARKer:VSTOp?
The :MARKer:VSTOp? query returns the time at the By marker position.
Returned Format
[:MARKer:VSTOp] <By_position><NL>
Example This example places the current setting of the By marker in the numeric
variable, varSetting, then prints the contents of the variable to the
computer's screen. Notice that this example uses the :MARKer:Y2? query
instead of the :MARKer:VSTOp? query.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MARKER:Y2POSITION?"
varSetting = myScope.ReadNumber
Debug.Print FormatNumber(varSetting, 0)
NOTE
Use :MARKer:Y2Position Instead of :MARKer:VSTOp
The :MARKer:VSTOp command and query perform the same function as the
:MARKer:Y2Position command and query. The :MARKer:VSTOp command is provided for
compatibility with programs written for previous oscilloscopes. You should use
:MARKer:Y2Position for new programs.
