Mask Test 11

InfiniiVision Oscilloscopes User’s Guide 347

• 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:

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:

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:
