.7 Using the Logic Trigger Function
・The signal of a logic channel can be used as trigger source.
・A trigger pattern and logical operator (AND/OR) are specified, and triggering
occurs when the trigger conditions are met.
・A trigger filter can be specified, so that triggering occurs only when the trigger
conditions are met within the filter width.
Method Screen: STATUS 2
(1) Set the logic trigger
1. Call up the STATUS 2 screen.
2. Move the flashing cursor to the position
shown in the figure on the left.
3. Use the function keys to select ON.
: Logic trigger is not used.
: Triggering occurs if any one of the logic
input signals conforms to the trigger
pattern.
: Triggering only occurs if all of the logic
input signals conforms to the trigger
pattern.
・If the conditions are met already when measurement is started (AND: all
trigger patterns are met, OR: one trigger pattern is met), triggering does not
occur at this slope. Triggering only occurs if the conditions are removed and
then met again.
・’AND’ cannot be set between the trigger sources using the logic trigger and
the RMS level trigger. When a shift is made from "OR" to "AND," the logic
trigger setting is turned OFF.
(2) Set the trigger filter.
Filter width is specified using sampling points.
1. Move the flashing cursor to the position
shown in the figure.
2. Use the function keys or the
JOG control to
