Agilent Technologies 24A, 54621D, 42A Qualifier time set softkey, When the duration trigger occurs

Triggering the Oscilloscope

To use Duration triggering

5Select a qualifier time set softkey (< or >), then rotate the Entry knob to set the duration qualifier time.

<qualifier time set softkey

•When the less than (<) qualifier is selected, the Entry knob sets the oscilloscope to trigger on a pattern duration less than the time value displayed on the softkey.

•When the within time range (><) qualifier is selected, the Entry knob sets the upper time range value.

•When the out of time range (<>) qualifier is selected, the Entry knob sets the lower time range value.

>qualifier time set softkey

•When the greater than (>) qualifier is selected, the Entry knob sets the oscilloscope to trigger on a pattern duration greater than the time value displayed on the softkey.

•When the within time range (><) qualifier is selected, the Entry knob sets the lower time range value.

•When the out of time range (<>) qualifier is selected, the Entry knob sets the upper time range value.

•When Timeout qualifier is selected, the Entry knob sets the timeout value.

When the duration trigger occurs

The timer starts on the last edge that makes the pattern (logical AND) true. The trigger will occur on the first edge that makes the pattern false if the time qualifier criteria of the pattern has been met, except in Timeout mode. In Timeout, the trigger occurs when the timeout value is reached while the pattern is true.
