Mask Command Group
Use
the commands in the Mask Command Group to compare incoming waveforms
against standard or u ser-defined telecommunications masks. Standard masks are
only available when option MTM is installed. Without option MTM, you need
to define your masks. When the instrument detects waveforms that fall inside or
outside of the mask limits, it can perform tasks such as generating hard copy,
saving the waveform, emitting a beep or an SRQ, stopping and waiting for your
i
nput, sending an E-mail message with specified data, logging the time/date of the
acquired waveform, or some combination of these actions.
A mask is a set of polygonal regions on the screen. Every vertical line of the
screen intersects the polygon in zero, one, or two places, but never in more than
two places. (A vertical line that intersec ts a vertical mask border is counted.) You
have to break up more complicated polygons into two separate segments. Unlike
limit testing, the inside of a mask is the region where waveform data would
not normally fall. A telecommunications standard requires up to eight of these
segments. Pulse standards always have two segments. Standards with eye patterns
usually have three masks, but some have four.
