Mask Testing 15
Keysight InfiniiVision 3000 X-Series Oscilloscopes User's Guide 247
Region number 1 is the top mask region. The vertices in Region 1 describe points
along a line; that line is the bottom edge of the top portion of the mask.
Similarly, the vertices in Region 2 describe the line that forms the top of the
bottom part of the mask.
The vertices in a mask file are normalized. There are four parameters that define
how values are normalized:
•X1
• ΔX
•Y1
•Y2
These four parameters are defined in the Oscilloscope Setup portion of the mask
file.
The Y-values (normally voltage) are normalized in the file using the following
equation:
Y
norm
= (Y - Y1)/ΔY
where ΔY = Y2 - Y1
To convert the normalized Y-values in the mask file to voltage:
Y = (Y
norm
* ΔY) + Y1
where ΔY = Y2 - Y1
The X-values (normally time) are normalized in the file using the following
equation:
X
norm
= (X - X1)/ΔX
To convert the normalized X-values to time:
X = (X
norm
* ΔX) + X1
Oscilloscope
Setup Information
The keywords "setup" and "end_setup" (appearing alone on a line) define the
beginning and end of the oscilloscope setup region of the mask file. The
oscilloscope setup information contains remote programming language
commands that the oscilloscope executes when the mask file is loaded.
Any legal remote programming command can be entered in this section.
