A → B → R

The trigger sequence "A → B → R" consists of two subsequent conditions: A-trigger and

B-trigger with optional B-trigger delay and count. In addition, a reset condition R can be

configured: timeout or R-trigger condition. A-, B-, and R-triggers are configured in the

same way.

After the A-trigger conditions have been met, and an optional delay has passed, the B-

trigger with independent conditions is enabled. The instrument waits until one or a

specified number of B-trigger conditions occur. If the reset condition is not fulfilled, the

latest B-trigger causes the trigger event, and then the sequence starts again. The B-

trigger can only cause the trigger event if it occurs after the A-trigger and after the

delay time.

If you expect, for example, an irregular B-trigger, you can configure a reset condition to

restart the sequence. The reset condition can be a simple timeout, and/or a reset event

that is defined in the same way as the A- and B-trigger conditions.

The "A → B → R" trigger sequence requires that input channels CH1...4 are set as trig-

ger sources for all conditions. All other input sources are disabled. The "A → B → R"

sequence is not available if one the following trigger types is set as A-trigger:

The instrument checks all trigger settings for compatibility and disables settings that do

not fit the previous settings in the sequence.

The B-trigger is the second condition of the trigger sequence. You can configure a

delay between the A- and B-trigger, and define a number of fulfilled B-trigger conditions

to be ignored. The B-trigger condition is configured in the same way as the A-trigger.

The instrument disables settings that do not fit the previous settings in the sequence.
