Description

Event recorded on specified clock via signal transmission from original time instant recorded on different clock.

Object Model

Public Properties

BaseClockLocation	The base clock location, which is a point from VGT.
OriginalTimeInstant	The original time instant.
SignalDelay	The Signal delay definition, which includes signal transmission, time delay convergence and signal path reference system.
SignalSense	The direction of the signal, whether you are Transmitting or Receiving from the BaseClockLocation.
TargetClockLocation	The target clock location, which is a point from VGT.

Example

Create and configure signaled event.
