14 Mask Testing
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.
The following mask file produced the mask shown above:
MASK_FILE_548XX
"All Regions"
/* Region Number */ 1
/* Number of vertices */ 4
-12.50, MAX
-10.00, 1.750
