DMB 3018  GPS Synchronizaton Clock Generator
The DMB-3018 GPS Synchronization Clock Generator is the key equipment for exciter and SFN Adaptor in SFN network, which provides the GPS synchronized 1 PPS and 10MHz clock for Exciter and SFN Adaptor. The DMB-3018 adopts smart predictive algorithm combined with excellent short time stability of the OXCO oscillator to mitigate the effects of inherent GPS noise. And it also complies to the stringent hold over mode requirements of DVB-T/H and GB20600 standards when GPS reference is lost. The DMB-3018 is the best choice of terrestrial digital television operators.
MAIN FEATURES

High performances GPS receiver to receive up to 12 simultaneous satellites
the OXCO oscillator to keep frequency and time accuracy
Generate 1 pps + 10 MHz High Accuracy-High stability signals for SFN applications
Continuous high precision output without GPS signals
Compatible with any SFN MIP inserter
Near rubidium stability incase of loss of satellite signals
Web browser remote control, SNMP is optional
