TheGMR1000andGMR5000arehigh‐precision,smallprofile,multi‐functionreferencegeneratorsthatcan
operateonanEthernetorTimeCodenetwork,orasastandalonemasterclockreference.OnanEthernetnetwork,
thebuilt‐
inNetworkTimeProtocol(NTP)clientaccuratelysetssystemtimefromoneortwoNTPservers.Fora
timecodesystem,atimecodereadersetssystemtimefromatimecodegenerator.
WhenequippedwithaGPSorGNSSreceivertheGMRcanlocktoGPSand/orGNSSsatelliteconstellations,

providingnear‐atomicclockprecision.TheGMRcanalsoreadNMEAandNENAmessagestosetitssystemtime,or
timecanbesetmanually,anditcangenerateNMEA,NENAorTruetime/Kinemetrics.Holdoveraccuracyand
stabilityismaintainedwithahigh‐stabilityTCXOoscillatorthatcanbeupgradedto

option.
OptionaloutputsincludeTimeCode(SMPTE,IRIG‐A,IRIG‐B,IRIG‐E),PPO(ProgrammablePulseOutput),PPS(Pulse
PerSecond),10MHzsinewave,andIEEE1588PreciseTimeProtocol.
