The 4370A DVB Sync Source is a flexible timing system designed for Single Frequency Network (SFN) synchronization for DVB/DAB applications. These applications require a precision time and frequency reference to synchronize transmitters across multiple locations. Without synchronization, networks are not able to reliably deliver video and audio content to the end user.
The 4370A enables DVB-T and DVB-H networks to be deployed across varied landscapes by providing access to low cost, reliable precision time and frequency reference signals, in multiple formats ensuring a robust and reliable network.
What distinguishes the 4370A?
Redundancy
- Time and frequency redundancy from multiple GPS,
E1 or fiber optic interface
- Power redundancy from hot swap AC or DC power supplies
- Output redundancy from hot swap output modules
Remote Management
- Easy to use setup, monitoring and control via SNMP
- Supports up to 8 locations
- Can be used with Symmetricom GUI or third party software
