How is mask testing done?

InfiniiVision oscilloscopes start mask testing by creating a database that is
200 x 640 for the waveform viewing area. Each location in the array is
designated as either a violation or a pass area. Each time a data point
from a waveform occurs in a violation area a failure is logged. If Test All
was selected, every active analog channel is tested against the mask
database for each acquisition. Over 2 billion failures can be logged
per- channel. The number of acquisitions tested is also logged and
displayed as "# of Tests".
The mask file allows greater resolution than the 200 X 640 database. Some
quantization of data occurs to reduce the mask file data for display
on- screen.
