Time Domain Trigger Tab
Figure 44 Time Domain Trigger Tab
Trigger Mode —
User can set for the time domain acquisition to begin on a rising or falling edge of the signal.
Internal —
User can select between using an internal trigger based on the upper and lower
thresholds.
External —
User can select the external trigger to accept a sync input to indicate the start of a
measurement.
Trigger Setup —
Allow the user to freely view the measurement signal without a trigger level.
Primarily used when configuring time domain view settings.
Rising/Falling Edge —
User can select between rising or falling edge of the voltage or
current signal to be used as the trigger.
Trigger Delay —
Trigger delay as a percentage. Percentage point at which the detected edge of the signal is in
reference to the measurement display.
Internal Trigger Operation
For rising-edge trigger, the lower threshold condition must be met, followed by the upper threshold condition
without violating the settling or expire time.
For falling-edge trigger, the upper threshold condition must be met, followed by the lower threshold condition,
without violating the settling or expire time.
Upper Threshold —
Trigger condition will be satisfied when the measurement rises above this threshold.
Lower Threshold —
Trigger condition will be satisfied when the measurement falls below this threshold.
Settling Time —
Minimum time between two trigger conditions
Expire Time —
Maximum time between two trigger conditions
Holdoff Time —
Specifies the amount of time, once the trigger condition has been met, during which additional
triggers will be ignored.
