"Logical
operator"
defines the logic combination of two sources. The sources are channel
1/2 and channel 3/4 on the first step, and in the second step the logical
combination resulting from the first step.
●
"AND": logical AND, conjunctive combination
●
"NAND": logical NOT AND
●
"OR": logical OR, disjunctive combination
●
"NOR": logical NOT OR

Trigger Levels
Provides an overview of the current trigger levels of all input channels. For qualification
and the pattern trigger, the trigger level is a decision treshold: If the signal value is higher
than the trigger level, the signal state is high (1 or true for the boolean logic). Otherwise,
the signal state is considered low (0 or false) if the signal value is below the trigger level.
Couple levels (Trigger level and hysteresis coupling)
Sets the trigger levels and hysteresis values for all channels to the values of the currently
selected trigger source. The function affects only the levels defined for the selected event
(A-, B-, or R-event). The hysteresis of the external trigger input is an independent value,
and it is not affected by level coupling.
In trigger sequences, event coupling of trigger levels is possible: "Couple levels of all
events" on page 82

Robust trigger qualification
Activates the robust trigger for the qualification channels. Thus you can set the robust
trigger separately for the trigger source and the qualification channels.
For details, see "Robust trigger" on page 61.
Qualify
Enables the settings for trigger qualification. As soon as a qualification pattern is defined,
the option is selected by default.
