Description
Enables/disables the detected pattern selection feature. This feature detects
and syncs to PRBS patterns only. When enabled, Pat Type is set to PRBS and
cannot be changed.
Displays the current pattern name (read only). Use the Pat Type and Name
menu items to select the desired pattern.
Sets the filter for the list of selectable patterns under "Name". Available filters
are PRBS, Factory, and User. If Auto Pattern is enabled and it cannot
determine the pattern type, the message "Unknown" is displayed.
Sets the pattern name from the list of patterns filtered by Pat Type.
Inverts all patterns. Cannot be changed when Auto Pattern is ON.
Executes a synchronization to synchronize to the incoming data stream
regardless of the setting for Sync Mode.
Displays the synchronization type (Normal).
Specifies whether the error detector will attempt to automatically synchronize
(Auto) to the incoming data stream or will synchronize only when the Sync
Now command is executed (Manual).
Displays whether the system is synchronized or has lost synchronization.
Sets the synchronization threshold to trigger a synchronization attempt. When
the Sync Mode is set to Auto and the BER rises above this threshold, the error
detector will attempt to synchronize to the incoming data stream
automatically. Range is 1E-2 to 1E-9.
Executes an auto alignment to adjust to the optimal sampling and delay
voltage.
Set SmplV: enables/disables auto sample voltage alignment.
SmplV Step: sets the sampling threshold voltage step size used during an
auto alignment to determine the optimal voltage.
Set Delay: enables/disables auto delay alignment.
Dly Step: sets the sampling delay step size used during an auto alignment to
determine the optimal sampling delay.
Eye Height: returns the eye height found during auto alignment.
Eye Width: returns the eye width found during auto alignment.
Last AutoAlign: returns the date and time of the last auto alignment.
