how to compare the trigger pulse relative to the pulse width as follows:

Positive pulse width less than pulse width setting

Positive pulse width larger than pulse width setting

Positive pulse width equal to pulse width setting

Negative pulse width less than pulse width setting

Negative pulse width larger than pulse width setting

Negative pulse width equal to pulse width setting

Pulse.

2. Press the Source option button to choose a

channel input or external input.

3. Press the When option button to select how

to compare the trigger pulse relative to the

value selected in the Set Width option.

4. Press the Set Width option button and then

oscilloscope does not display a waveform

until after the first trigger). Use Single mode

when you want the oscilloscope to acquire a

single waveform.
