MASK:COUNt:WAVEFORMS? (Query Only)
This query returns the number of waveforms that have been acquired and
processed during pass/fail mask testing.
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

MASK:CUSTom (
No Query Form)
This command initializes a custom mask using a default triangle segment 1 mask
(
:MASK:CUSTOM INIT), or copies the currently active mask to the user-defined
custom mask (
:MASK:CUSTOM COPYActive).
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.

Syntax
MASK:CUSTom {INIT|COPYA CTive}
Related Commands
MASK:USER:AMPLitude,
MASK:USER:WIDth,
MASK:MARgin:PERCent
Arguments
INIT sets the user-defined custom mask to its initialized state.
COPYACTive copies the currently active mask to the user-defined custom mask.
Examples
MASK:CUSTom INIT creates an initialized user-defined custom mask.
MASK:DISplay
This command controls whether a mask is displayed on the screen. This is useful
for temporarily turning off masks without deleting them. This is equivalent to
pushing the bottom bezel "Setup Mask" button, and then pushing the side bezel
"Display Mask" button.

Related Commands
MASK:TEMPLate:CREATEmask
Arguments
ON shows the mask on the display. This is the default value.
OFF removes the mask from the display.
0 removes the mask from the display;
1 shows the mask on the display.
Examples
MASK:DISplay ON shows the mask on the display.
MASK:DISplay? might return 0, indicating that the mask is not being shown
on the display.
MASK:LOCk
This command locks the mask to the source waveform so that any changes made
to the horizontal and/or vertical scale settings of the waveform will redraw the
mask segments in proportion. This feature is useful for expanding the horizontal
and/or vertical settings in order to zoom in on waveforms and masks, and visually
examine violation areas in more detail.
