MS-250 Mixed Signal Oscilloscope Option

Interval Trigger

Interval triggers upon finding a specific interval, the time (period) between two

consecutive edges of the same polarity: positive to positive or negative to negative. Use the

interval trigger to capture intervals that fall short of, or exceed, a specified range.

On the Trigger dialog, select Smart trigger type, then Interval to display the controls.

1. Choose the Source input line.

2. Choose the Slope (edge) from which to measure.

3. Choose the Logic Family that marks the High-Low logic threshold. To enter a custom

threshold, choose Logic Family User Defined and enter the voltage Level.

NOTE: The Logic Family will default to any Logic Setup associated with that line in a

previous digital group setup.

4. Use Interval Condition is settings to create an expression describing the triggering

interval. This may be:

l Any width Less Than an Upper Value.

l Any width Greater Than a Lower Value.

l Any width In Range or Out Range of values. You may describe the range using

either:

l Limits, an absolute Upper Value and Lower Value.

l Delta, any Nominal width plus or minus a Delta width.
