Description

Determines what interval is recorded at target clock location by performing signal transmission of original interval between base and target clock locations.

Object Model

Public Properties

BaseClockLocation	The base clock location, which is a point from VGT.
OriginalInterval	The original interval.
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 interval.
