"Off"
No timing condition, only the logical pattern condition is relevant.
"Timeout"
Defines a minimum time qualification to avoid triggering on unstable or
transitional conditions. Even in best-designed systems, there are slight
delays between the signal when digital signals change states. This
means that there are always transitional state conditions when signals
are switching.
See "Timeout settings" on page 340 for a description of the settings.
The trigger event occurs when the pattern stays unchanged for the
specified time.
"Width"
Sets a pulse width as timing condition, see "Width set-
tings" on page 340. The pulse starts when the pattern comes true, and
the trigger event occurs when the pattern comes false during the speci-
fied time limit.
Using this mode, you can, for example, trigger exclusively on unstable
conditions - if the pattern is present for less than a specified time.
SCPI command:
TRIGger<m>:PARallel:PATTern:MODE on page 750
Timeout settings
The timeout settings "Range" and "Time" appear if the timing mode is set to "Timeout".
Range ← Timeout settings
Sets the state condition:
"Stays high"
The pattern stays true for the specified time.
"Stays low"
The pattern stays false for the specified time.
"High or low"
The pattern remains unchanged for the specified time.
SCPI command:
TRIGger<m>:PARallel:PATTern:TIMeout:MODE on page 750
Time ← Timeout settings
Defines the time limit for the timeout at which the instrument triggers.
SCPI command:
TRIGger<m>:PARallel:PATTern:TIMeout[:TIME] on page 750
Width settings
The width settings "Range", "Width" and "±Delta" appear if the timing mode is set to
"Width".
Range ← Width settings
Selects how the range of a pulse width is defined:
"Within"
Triggers when the pattern comes false inside a given time range. The
time limit is defined by Width ± Delta.
"Outside"
Triggers when the pattern comes false before or after the given time
range. The time limit definition is the same as for "Within" range.
"Shorter"
Triggers when the pattern comes false before the given "Width" has
expired.
