Mask Test 11
InfiniiVision Oscilloscopes User’s Guide 343
X
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)/Y
where Y = Y2 - Y1
To convert the normalized Y-values in the mask file to voltage:
Y = (Y
norm
* Y) + Y1
where Y = Y2 - Y1
The X-values (normally time) are normalized in the file using the following equation:
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
