25.0 µs Adjustment with the stylus using the time setting scroll bar
Double-tapping in this field displays a virtual numeric keypad which can be used
to directly input the value.
The choice of the or edge in the "Main" tab defines the limits of the

Example
Signal injected on CH1: 1 pulse of 50 µs (repetitive or not)
The trigger parameters in the main menu are active (Source, Level, Edge, etc.).
The oscilloscope is triggered when the signal's pulse width is equal to the
specified pulse width (25.0 µs + tolerance).
The trigger occurs on the ascending edge of the pulse, but is effective on the
trailing edge.
