"Coupling"
The current coupling or ground connection is shown for each channel
and can be changed directly in the pattern, if necessary.
"Boolean
operator"
Defines the logical operation on the digital signal resulting from the
comparison with the trigger level.
●
"Direct": leaves the input value unchanged
●
"NOT": inverts the input value
"Logical
operator"
Defines the logic combination of two sources. The sources are chan-
nel 1/3 and channel 2/4 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
Define the trigger level for each input channel. For state and pattern trigger, the trigger
level is a decision threshold: If the signal value is higher than the trigger level, the sig-
nal state is high (1 or true for the Boolean logic). Otherwise, the signal state is consid-
ered low (0 or false) if the signal value is below the trigger level.
You can set the trigger levels for all channels to the same value, see "Couple levels
(Trigger level and hysteresis coupling)" on page 255.
Additional settings: Timing
"Timing" adds time limitation to the pattern condition.
Tap "Additional settings" to open the timing setup.
"Off"
No time limitation. The trigger occurs if the pattern condition is fulfil-
led.
"Timeout"
Defines how long the result of the pattern condition must be true or
false.
"Width"
Defines a time range for keeping up the true result of the pattern con-
dition. The range is defined in the same way as for width and interval
triggers, see "Range" on page 246.
