39 www.test-tree.com SFN Synchronization monitoring on Transmission site (TX) – Time, Frequency, Network Delay SFN Synchronization and signal interference monitoring on Reception site (RX) – Echo monitoring with Echo Pattern mode: more precise echo in error identification, even if the main echo suffers changes! Unique TestTree feature RF signal time synchronization: measure the RF frame transmission time drift/delay RF signal frequency synchronization: measure the Carrier Frequency drift Before modulation: measure the TS Network Delay between HE and TX site
