Markers Pattern When the markers are set to pattern you can specify patterns that the logic
analyzer will place the markers on. You can also specify how many
occurrences of each marker pattern the logic analyzer looks for. This use
of the markers allows you to find time between specific patterns in the
acquired data.
Patterns for each marker (X and O) can be specified. Patterns can be
specified for both markers in each label, however, the logic analyzer can
only search one label at a time. You can also specify whether the marker is
placed on the pattern at the beginning of its occurrence (entering) or end
of its occurrence (leaving).
Another feature of markers set to patterns is the Stop measurement when
X-O ____, which is in the pop-up that appears when you select Specify
Patterns. The options are:
• Off
• Less than
• Greater than
• In range
• Not in range
With this feature you can use the logic analyzer to look for a specified
time or range of time between the marked patterns and have it stop
acquiring data when it sees this time between markers (The X marker must
precede the O marker).
Note The upper and lower range boundaries must not be the same value. For
example, if you want to stop a measurement when the X and O markers
are in range of 200 ns, you should set the range values to 190 ns and 210
ns. This eliminates erroneous measurement termination.
