5.1 General Information
Time stamps
and events
Time stamps are useful when analyzing incoming or outgoing data or event
sequences on a specific bus.

Generating
time stamps
Each event which is sent or received by a Vector network interface has an accurate
time stamp. Time stamps are generated for each channel in the Vector network inter-
face. The base for these time stamps is a common hardware clock in the device.

If the measurement setup requires more than one Vector network interface, a syn-
chronization of all connected interfaces and their hardware clocks is needed.
Due to manufacturing and temperature tolerances, the hardware clocks may vary in
speed, so time stamps of various Vector devices drift over time.
