Returns
Integer
Examples
MASK:USER:SEG3:NR_Pt? might return 0, indicating that there is no segment
3 in the current mask.
MASK:USER{:SEG<x>|:MASK<x>}:POINTS
This command specifies the x and y coordinates of the points that make up the
segment 1–8. The units are normal wave
form units. The x-coordinate is specified
relative to the trigger. The points are specified as a sequence of (x,y) points which
traverse the boundary of the segment in a counter-clockwise direction.
A series of examples showing how to use mask commands for typical tasks
is included in an appendix. (See page E-1, Mask/Limit Command Sequence
Examples.)
Conditions
This command requires a DPO4LMT application module for 4000 series models,
and an MDO3LMT application module for MDO3000 series models.

MASK:USER:TR
IGTOSAMP
This command specifies the nominal time, in seconds, from the (leading edge)
trigger position to the pulse bit sampling position, to be used for testing with
auser-define
dcustommask.
NOTE. When you create a custom mask, the horizontal position setting i s
converted from percent to time, and sets the trigtosamp value. If you change
trigtosamp value a fter the mask has been displayed, the mask will be horizontally
offset, and the segment x values recalculated. Note that the segment x values are
the relative time between the trigger position and the mask point's x value.

Arguments
<NR3> is a floating point number that sets the time to the pulse bit sampling
position.
Examples
MASK:USER:TRIGTOSAMP 50.0000E-6 sets the time from the trigger position
to the pulse bit sampling position to 50 μS.
MASK:USER:TRIGTOSAMP? might return 100.0000E-6, indicating that a time
of 100 μS has been specified.
