Base StationsGPS161ER OEM GPS Receiver with External Reference
MEINBERG's GPS161ER is already finding its way into the compact base stations of Digital Video Broadcasting – Terrestrial (DVB-T) applications. The compact size of the boards allows easy integration of GPS controlled timing into synchronization tasks.
As with the rest of the MEINBERG GPS family, the standard down converter design of the GPS Antenna supplied with the GPS161ER provides easy installation of up to 300 meters (over 980 feet) of RG-58 antenna coax cable.
