Remote command:
TRIGger:A:PATTern:SOURce on page 469
And | Or
Sets the logical combination of the channel states.
"AND"
All defined states must be true.
"OR"
At least one of the defined states must be true.
Remote command:
TRIGger:A:PATTern:FUNCtion on page 469
Duration
The switch has the following two effects:
●
Selects the mode of the True | False comparison.
●
Enables or disables the Time limitation.
True | False
Defines whether the instrument triggers on fulfillment of the logical condition, or on vio-
lation.
●
If Duration = on, the instrument triggers when the logic combination "Is True" or
"Is False" for a specified time duration.
●
If Duration = off, the instrument triggers when the logic combination is found in the
signal ("Goes True"), or if it disappears ("Goes False").
Remote command:
TRIGger:A:PATTern:CONDition on page 469
Time limitation
To set a time limitation for the pattern, you have several possibilities. They are similar
to the setting of a pulse width, see Chapter 6.6, "Width trigger", on page 85.
●
"Timeout" and "Time t"
Define a minimum time during which the signals match the pattern condition.
●
"Width >" or "Width <" and "Time t"
Triggers if the pattern condition changes before or after the specified time.
●
"Width =", "Time t1" and "Variation"
Triggers if the pattern condition is fulfilled for a duration "Time t1" ± "Variation".
●
"Width ≠", "Time t1" and "Variation"
Triggers if the pattern condition is fulfilled for a duration shorter than "Time t1" -
"Variation", or longer than "Time t1" + "Variation".
●
"Inside", "Time t1" and "Time t2"
Triggers if the pattern condition is fulfilled for a duration between "Time t1" and
"Time t2". These settings are an alternative setting to the definition with "Width =".
The time values are interdependent and adjusted accordingly.
●
"Outside", "Time t1" and "Time t2"
Triggers if the pattern condition is fulfilled for a duration shorter than "Time t1", or
longer than "Time t2". These settings are an alternative setting to the definition with
"Width ≠". The time values are interdependent and adjusted accordingly.
