Triggers
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.
6 Press the qualifier softkey ( < > >< ) to select the time qualifier.
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:
• Greater than a time value ( > ).
For example, for a positive pulse, if you set t>10 ns:
• Within a range of time values (
><
).
For example, for a positive pulse, if you set t>10 ns and t<15 ns:
7 Select the qualifier time set softkey ( < or > ), then rotate the Entry
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).
