"victim" channel. At least one active channel should have a specific
termination criteria. Setting all channels to terminate on Other
Channel would be the equivalent of specifying Run Forever.
Note: The test termination conditions can be channel-specific. If
different termination conditions are selected on different
channels, the test will continue to run until all termination
conditions on all channels have been met.
Eye Preview
The Eye Preview panel provides a calculated simulation of the
expected jitter eye diagram as it would be displayed on an
oscilloscope. The eye preview is useful for quickly determining
the approximate level of signal impairment based on the current
system settings.
Note the simulated Eye Preview does not include the affects of
common mode interference or low frequency SJ because this
affect is typically cancelled out by a differential probe and a
scope PLL and does not generally show up on most scope eye
diagrams. Also, including this affect in the calculated eye
diagram is generally not useful as it often results in a completely closed eye.

Clicking on the Options tab brings up the following panels:
Default Settings
The Default Settings panel allows the user to
establish the default values that appear whenever a
protocol, number of channels, or Host/Device setting
is required. Establishing these default values saves
the user time in not needing to change values
constantly when working on a particular development
project.
The Auto display graph option, if selected, will result
in a new graph being displayed and updated in real
time whenever you run a test that records results.
