SDS5000X Series Digital Oscilloscope User Manual
Limit Range
When the logic is "AND" or "NOR", the time limit condition is available. This
setting is particularly useful to filter the hazard signals of combinational logic.
When the logic is "OR" or "NAND", the time limit setting is not supported.
Holdoff can be set in pattern trigger, see the sections " Holdoff" for details.
15.5.11 Qualified Trigger
Qualified trigger is an edge trigger after a user defined qualified condition is
satisfied. So a qualified trigger has two sources; one is the source of the edge
trigger, the other is the qualified source.
The qualified types include “State”, “State with Delay”, “Edge” and “Edge with
Delay”. When the type is “State”, the oscilloscope triggers on the first edge
when the qualified source is in the specified state (High or Low). When the
type is “State with Delay”, a time limit condition is also available.
