In other words, the Advance the Sequence button is the link between two states in a
multi‐state sequence. The Advance the Sequence arrow tells the analyzer to go to the
next state if it detects the event at the tail (origin) of the arrow.
The Action pop‐up menu has the following restart and trigger options:
 Restart the Sequence (not shown): Restarts the sequence. Note that this option
is context‐sensitive and only appears if you have created a multi‐state sequence.
A thick arrow appears from the selected event and point upward towards the
first event in the sequence.
 Restart All: Restarts all rules in all sequences and in the global state and displays
an arrow and a Restart All button. This action precludes selecting Advance the
Sequence and Restart the Sequence.
 External Trigger Pulse HIGH: Sends an output signal with a Pulse High format
through the output ports on the back of the UPAS. Pulse High is the default for‐
mat. Pulse High causes the analyzer to transmit a 5‐volt, 40‐nanosecond signal.
Teledyne LeCroy Protocol Analyzers use a TTL compatible output driver. This
driver is not intended to drive a 50 ohm DC load. When doing so the output level
is reduced from 3.3 volts to 2.2 volts. This does not harm the output driver. To
see the full level, it is required to change the input impedance on the device
receiving the trigger from 50 ohms DC to high impedance.
 Properties: Displays the Action Properties dialog for the selected action.
Event Pop-up Menu
If you click an Event button in the Main Display area, the Event pop‐up menu appears. The
Event pop‐up menu has the following options:
 Specify Action(s): Opens the Actions submenu, allowing you to assign an action
to the event. Options on this submenu are the same as those on the Action pop‐
up, described previously.
 Add Counter: Adds a counter to count a specified number of times the event
occurs before the analyzer executes the corresponding action.
 Move Event to: Moves the selected event to a different position in the Recording
Rules window.
 Copy Event to: Copies the selected event to a different position in the Recording
Rules window.
 Delete This Event: Deletes the selected Event. Alternatively, you can use the
Delete button on the toolbar or keyboard to delete events.
 Properties: Displays the Event Properties dialog for the selected event.
