Logical expression
Defines a logic combination of several digital channels as trigger condition if
"Logic"
is
set for "Source". The "Qualification Editor" supports the entry of the expression.
Remote command:
TRIGger<m>:PARallel:TIMeout:EXPRession[:DEFine] on page 2433
TRIGger<m>:PARallel:STATe:EXPRession[:DEFine] on page 2433
TRIGger<m>:PARallel:PATTern:EXPRession[:DEFine] on page 2433
TRIGger<m>:PARallel:SPATtern:EXPRession[:DEFine] on page 2433
Mode: Off, Timeout, Width
Sets the mode of the timing condition.
"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 1006 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 settings"
on page
1007. 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 unsta-
ble conditions - if the pattern is present for less than a specified time.
Remote command:
TRIGger<m>:
PARallel:
PATTern:MODE on page 2438
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.
Remote command:
TRIGger<m>:PARallel:
PATTern:TIMeout:MODE on page 2438
Time ← Timeout settings
Defines the time limit for the timeout at which the instrument triggers.
Remote command:
TRIGger<m>:PARallel:PATTern:TIMeout[:TIME] on page 2438
