Manual Common Features

4.1.3 Hardware Sync

Synchronization

by hardware

A more accurate time synchronization of multiple devices is provided by the hardware

synchronization which has to be supported by the application (e. g CANalyzer,

CANoe). Therefor two Vector network interfaces can be connected with the

SYNCcableXL (see accessories manual, article number 05018).

Figure 6: SYNCcableXL to synchronize two devices over 3-pin connector (Binder type 711).

In order to synchronize up to five devices at the same time, a distribution box is

available (see accessories manual, article number 05085).

At each falling edge on the sync line which is initiated by the application, the Vector

network interface generates a time stamp that is provided to the application. This

allows the application to calculate the deviations between the network interfaces and

to synchronize the time stamps to a common time base (master clock) which is

defined by the application.

Figure 7: Time stamps are synchronized to the master clock (accuracy in range of 1 µs).

Note: The hardware synchronization must be supported by the application. For

further information please refer to the relevant application manual. Please note that

the software synchronization must be disabled (see Vector Hardware Config |

General information | Settings | Software time synchronization) if the hardware

synchronization is used.
