High stability & high accuracy GNSS disciplined oscillator(OCXO)ADEV: Less than 2e-12@1s1s-1000s, ADEV Less than 5e-12 (Typical), when tracked GNSS for a long time (more than the 3days, typically)Frequency accuracy: Less than 1e-12Hz when tracked GNSS (24 hour averaging)10MHz clock output as sine-wave and square-wave1PPS timepulse output synchronized to GNSSConfigurable NMEA messages via USB portGPS + BD(Compass) dual GNSS, max. 32 receiver channels, ensuring more satellites to be received at the same timeA high performance disciplined OCXO insideGPS/COMPASS dual mode GNSS receiver, more satellites can be received at the same time (32-Channel max.). Configurable GNSS receive mode via USB port:GPS, COMPASS or GPS + COMPASS, and the NMEA messages is also configurable.Outputs: 1-Ch 10MHz Sine-Wave + 1-Ch 10MHz Square-Wave + 1-Ch 1PPS TimepulseInput: GNSS Antenna Input, With 3.3V Antenna FeedPWR: Power-on indicatorTRACK: Tracking GNSS indicator. Slow flicker when OCXO model training is completed. Fast flicker when tracked GNSS, but the OCXO model training is not completedGNSS: Indication if the GNSS receiver worked goodCOM: Data transmission indicatorUSB: Mini USB port12V DC: 12V/1A power supply inputPlug Type :EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.Colour:Black+grayMaterial:Plastic + MetalPackage Contents:1 * GNSS Disciplined Oscillator1 * Power Adapter1 * USB Cable1 * GPS/COMPASS Dual Mode AntennaOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
