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
•
• 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
where Y = Y2 - Y1
To convert the normalized Y- values in the mask file to voltage:
Y = (Y
where Y = Y2 - Y1
The X- values (normally time) are normalized in the file using the
following equation:
X
To convert the normalized X- values to time:
X = (X
Oscilloscope The keywords "setup" and "end_setup" (appearing alone on a line) define
Setup Information 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.
