How Infiniium does Mask Testing
When you start the mask test, Infiniium creates a database that has unique
locations for every pixel in the waveform viewing area. Each location in the
database has a 21-bit counter for a maximum count of 2,097,151.
Each time a data point from a channel memory illuminates a pixel in the
waveform viewing area, the counter for that pixel is incremented. During mask
testing, any data point that illuminates a pixel in the mask violation region
causes a mask test failure.
The oscilloscope’s database continues to build until the oscilloscope stops
acquiring data or until mask testing is deactivated.
The oscilloscope’s database is also used for histogram analysis and color grade
persistence. Refer to the Infiniium help system for detailed information about
these other waveform analysis features.
How to do Mask Testing
The remaining topics in this chapter show you how to do mask testing.
Chapter 3 shows the standard masks supplied in the Mask Template Kit.
Make a copy of the Mask Test disk
A disk containing the standard masks is shipped with Infiniium Option 100 and
E2625A. Before you install the Mask Test templates, you should make a copy
of the Mask Test master disk and use the copy of the Mask Test disk for the
installation.
