X
norm
= (X - X1)/X
To convert the normalized X-values to time:
X = (X
norm
* X) + 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.
The mask scaling controls how the normalized vectors are interpreted.
This in turn controls how the mask is drawn on the display. The remote
programming commands that control mask scaling are:
:MTES:SCAL:BIND 0
:MTES:SCAL:X1 -400.000E-06
:MTES:SCAL:XDEL +800.000E-06
:MTES:SCAL:Y1 +359.000E-03
:MTES:SCAL:Y2 +2.35900E+00
Building a Mask File
The following mask uses all eight mask regions. The most difficult part of
creating a mask file is normalizing the X and Y values from the time and
voltage values. This example shows an easy way to convert voltage and
time to normalized X and Y values in the mask file.
