The selected pulse polarity is displayed in the upper- right corner of the
display. A positive pulse is higher than the current trigger level or
threshold and a negative pulse is lower than the current trigger level or
threshold.
When triggering on a positive pulse, the trigger will occur on the high
to low transition of the pulse if the qualifying condition is true. When
triggering on a negative pulse, the trigger will occur on the low to high
transition of the pulse if the qualifying condition is true.
The Qualifier softkey can set the oscilloscope to trigger on a pulse
width that is:
• Less than a time value (<).
For example, for a positive pulse, if you set t<10 ns:
10 ns
• Greater than a time value (>).
For example, for a positive pulse, if you set t>10 ns:
10 ns
• Within a range of time values (><).
For example, for a positive pulse, if you set t>10 ns and t<15 ns:

knob to set the pulse width qualifier time.
The qualifiers can be set as follows:
• 2 ns to 10 s for > or < qualifier (5 ns to 10 s for 350 MHz and lower
bandwidth models).
