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.
