Commands Listed in Alphabetical Order
Arguments
<NR3> isafloati
ng point value that specifies the timing resolution used to a draw
a user-defined custom mask pulse shape.
Examples
MASK:USER:HSCALE 200E–9 sets the nominal timing resolution used to draw the
mask pulse shape to 200 nanoseconds per division.
MASK:USER:HSCALE? might return :MASK:USER:HSCALE 40.0000E–9,
indicating that the nominal timing resolution used to draw the mask pulse shape
is set to 40 nanoseconds per division.
MASK:USER:HTRIGPOS
This command specifies the nominal trigger position (pulse leading edge), to be
used to draw a user-defined custom mask, as a fraction of the display width.
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
Syntax
MASK:USER:HTRIGPOS <NR3>
MASK:USER:HTRIGPOS?
Related Commands
MASK:CUSTom,
SAVe:MASK
Arguments
<NR3> is
a floating point number in the range of 0.0 to 1.0 that sets the trigger
points as a fraction of the display width, referenced from the left edge of the
graticule.
0.0 represents the left edge.
Examples
MASK:USER:HTRIGPOS 0.6 sets the nominal trigger position of the mask to 0.6.
MASK:USER:HTRIGPOS? might return :MA SK:USER:HTRIGPOS 500.0000E–3,
indicating that the nominal trigger position of the mask is set to 0.5.

<NR1> is an integer that sets the record length value to be used for pulse mask
testing of a user-
defined custom mask.

Ordlength 5000
sets the record length for pulse mask testing
with a user-defined mask to 5,000.
MASK:USER:RE
COrdlength?
might return 5000, indicating that a record length
of 5,000 has been set.
MASK:USER{:SEG<x>|:MASK<x>} (No Query Form)

MASK:USER{:SEG<x>|:MASK<x>}:NR_Pt? (Query Only)
This query returns the number of points that make up the specified mask segment
of a user-defined custom mask. There can be up to 8 segments.
A series of examples showing how to use mask commands for typical tasks
