11. Still receiving from DAB Without audio discontinuity
Seamless Linking Test
Service Linking: Just switching channel  make audio discontinuity
Seamless Linking: Switching channel without audio discontinuity
Easy Seamless Linking Test using two RWC2010B
One Tester works as a Master and the other works as a Slave
Provide Audio Time Delay adjust parameter between two units
MASTER
Still receiving from DAB
Receiving from DAB
Receiving from FM
Without audio discontinuity
DAB
Sync Cable
SLAVE
FM with RDS
Master & Slave are broadcasting synchronized the same audio

12. Single Frequency Network (SFN)
Easy emulate SFN environment using two RWC2010B
One Tester works as a Master and the other works as a Slave
Two RWC2010B transmit exactly synchronized signal
Signal delay adjustable with 0.1us resolution
MASTER
DAB
Sync Cable
SLAVE
Receiving signal from two RWC2010B
DAB
Master & Slave are broadcasting synchronized signal
