case the timestamp correlation will fail. This functionality should not be used
with virtual cameras such as the hard-coded example and network capturing.
The signal Trigger 1 can only be enabled if Trigger 0 is also enabled. The
frequency is forced to the same value as for Trigger 0. However, it is possible
to specify a time oset, which is the delay from a rising edge of Trigger 0 to a
rising edge of Trigger 1. Furthermore, Trigger 1 can have a pulse width that
diers from Trigger 0.
9.8 Time Synchronization
The `time synchronization' page, which is shown in Figure 19, can be used to
congure three possible methods for synchronizing SceneScan's internal clock.
As explained in Section 8.3, the internal clock is used for timestamping cap-
tured camera frames.
The rst option is to synchronize with a time server, using the Network
Time Protocol (NTP) up to version 4. In this case SceneScan synchronizes
its internal clock to the given time server, using Coordinated Universal Time
(UTC). The accuracy of the time synchronization depends on the latency of
your network and time server. If NTP time synchronization is active, synchro-
nization statistics are displayed in a dedicated status area.
As an alternative to NTP, the Precision Time Protocol (PTP) can be used
