Glossary Item Box

Gets or sets the trigger jitter range.

Syntax

Visual Basic (Declaration) 
Public Overridable Property TriggerMargin As Double
C# 
public virtual double TriggerMargin {get; set;}
C++/CLI 
public:
virtual property double TriggerMargin {
   double get();
   void set (    double value);
}

Property Value

The default value is 50e-6 seconds.

Remarks

This value is only used When the AcquisitionMode is AcquisitionMode.FrameTrigger or AcquisitionMode.SlotTrigger. When the start of measurement data is aligned with frame boundary or slot boundary, setting AcquisitionMode as AcquisitionMode.FrameTrigger or AcquisitionMode.SlotTrigger can minimize the required data length, also it can speed up the frame or slot boundary search. When data comes from hardware, this parameter indicates the trigger jitter range, and it decides how many additional data points are captured to ensure that the frame/slot boundary is present in the captured data, it also decides over which range the frame/slot boundary is searched. For example, if the trigger occurs at t0(trigger delay is already considered), the result length is T, pre-settling for filtering and data processing is PreSettling, and post-settling for filtering and data processing is PostSettling. Then data capture starts at t0 - PreSettling - TriggerMargin, and ends at t0 + T + PostSettling + TriggerMargin. So the total captured data duration is T + PreSettling + PostSettling + 2 * TriggerMargin. The frame/slot boundary is searched from t0 - TriggerMargin to t0 + TriggerMargin. When data comes from recording or user input, the data is assumed to be captured according to the above formula. If we mark the timing of the first sample as 0, then the slot/frame boundary is search from PreSettling to PreSettling + 2 * TriggerMargin.
