Commands Listed in Alphabetical Order
MASK:MASK<x>
:POInts
This command sets or queries the points (vertices) in the specified mask
in waveform coordinates. The mask is specified by <x>, which can be 1
through 8. Wh
en you send this command, any currently existing points in the
mask are deleted. Each point or vertex is an xy coordinate that represents a
horizontal/vertical pair in source waveform (user) units. The order of the pairs has
no effect on the mask created.
If the vertical or horizontal scale or position changes after this command is
executed, a query will return different values for the vertices. This is because
the mask polygons remain stationary on the display, but the relationship of the
internal coordinate system to the a bsolute user values changes.
NOTE. If
the specified mask is undefined, a query will return 0,0.

Syntax
MASK
:MASK<x>:POInts <NR3>,<NR3>,<NR3>,<NR3>, [..., ...]
MASK:MASK<x>:POInts?
Arguments
NR3 is the pair of x y coordinates for a point (vertex) in the mask. Each mask
polygon can have a maximum of 50 points or vertices. You must specify more
than two pair of points, otherwise the mask is marked as undefined, and the points
are ignored. The default is no points in the mask.
Examples
MASK:MASK7:POINTS -2.3E-9,44E-3,-2. 5E-9,47E-3,1.2E -9,40E-3
defines the points in Mask 7.
MASK:MASK3:POINTS? might return MASK:MASK3:POINTS

indicating the points in Mask 3.
MASK:MASK<x>:POINTSPcnt
This command sets or queries the points (vertices) in the specified mask in
percentage coordinates. The mask is specified by <x>, which can be 1 through 8.
Any currently existing points in the mask are deleted. The upper leftmost point is
0,0, and the lower rightmost point is 100,100.
Each mask polygon can have a maximum of 50 points or vertices. If more than 50
points are specified, an error is generated and the extra points are ignored. If any
