A dialog opens where you can configure the second event.
6. Optionally, set the "After 1st event wait" that the instrument waits after an A-trigger
until it recognizes B-triggers.
7. Set the "2nd event count". The last B-trigger causes the trigger.
8. You can also define a reset condition. The sequence restarts with the A-trigger if no
B-trigger occurs and the reset condition is fulfilled.
a) To specify a reset by timeout, enable "Reset on timeout", and enter the "Rest
timeout".
b) To specify a reset trigger type condition, enable "Reset event" and configure
the reset trigger type.
The trigger types and settings depend on the A and B trigger settings. The
instrument provides only possible, reasonable combinations.

Qualifying the trigger
Qualification considers the states of digital signals on other input channels and their
logical combination as an additional trigger condition. For example, an edge trigger is
configured for channel 1, and the instrument triggers only if the signal on channel 2 is
high.
For details on qualification settings and restrictions, see
1. On the "Menu", select "Trigger" > "Qualify" tab.
2. Set the channel(s) with the input signal to be used as qualifying signal(s) to "On".
The channel used as trigger source cannot be used for qualification.
3. Check and set the threshold levels for all used channels, that is, the thresholds for
digitization of analog signals.
4. Set the signal state for each channel: high or low.
5. If more than one channel is selected, set the logical combination of the channel
states.
6. If not yet enabled, tap "Qualify" to enable the qualification.

Trigger types
The setup of the trigger type is the most important part of the trigger definition. It deter-
mines the method to identify specific signal phenomena. Almost all trigger types are
available for all conditions in a trigger sequence, that is, you can combine different
types in the sequence. The instrument checks the trigger settings for compatibility and
feasibility, and disables settings that do not fit the previous settings in the sequence.
