To set window trigger via the Relative window type
When the window trigger type is set to "Relative", touch the
trigger descriptor box. The pop-up menu will show two user-
defined parameters: “Level +/-Delta" and "Level Center".
The above two parameters can be set in the following two
ways:
1. Select the parameter in the Level +/-Delta area of the
quick menu, then set the parameter value by the virtual
keypad or the Level knob on the front panel. Setting the
center level is similar.
2. Directly use the Level knob on the front panel. Press the
knob to switch between “Level +/-Delta" and "Center
Level", and rotate it to set values.
Note
: "Level +/-Delta” represents half of the actual window area. For example, when the
value is 200 mV, it actually represents a range of ± 200 mV, which is a 400 mV window.
Holdoff, coupling, and noise reject can be set in window trigger, see the sections
"Holdoff", " Trigger Coupling" and " Noise Reject" for details.
15.5.7 Interval Trigger
Trigger when the time difference between the neighboring rising or falling edges meets
the time limit condition.
When the trigger condition is set as an interval between two neighboring rising edges
and it is less than the set time value, the trigger diagram is as follows:
Trigger source, slope (rising, falling), limit range and time value can be set in the trigger
dialog box. Holdoff, coupling, and noise reject can be set in the interval trigger, see the
sections " Holdoff", " Trigger Coupling" and " Noise Reject" for details.
