How is mask testing done?
InfiniiVision oscilloscopes start mask testing by creating a database that is
256 x 1000 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. 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 256 X 1000 database.
Some quantization of data occurs to reduce the mask file data for display
on- screen.
