Evaluate synchronization feature by measuring timestamp jitter
Sample code to calculate timestamp jitter
MiiVii device provides sample code for users to evaluate the synchronization feature.
#navigate to the following directory
cd /opt/miivii/feature/sync_test/bin
#evaluate sync-out method performance
./sync_out_test
#evaluate sync-in method performance
./sync_in_test
#evaluate pps synchronization method performance
./pps_test
Sync out jitter measurement
Sample code(sync_out_test) could run real-time analytics on the received timestamp. Time interval, frequency, max deviation and standard
deviation are printed out.
