X300 Compact NMEA Tester

The X300 Smart NMEA Tester is a sub-compact and ultra-light portable NMEA 0183, reader. Complete with a built-in non-critical oscilloscope function.

With the ability to monitor NMEA 0183 data. Also, diagnose signal issues and furthermore predict failures due to signal quality. The X300 is the world’s first complete NMEA 0183 maintenance tool.

  • Monitoring, checking, and also analysis function of NMEA 0183(IEC61162-1/2) data
  • General-purpose Oscilloscope. Which can additionally diagnose NMEA 0183 signal and electric signal
  • Receive NMEA 0183 data without regard to the existing circuits by using High Impedance circuit
  • Receive NMEA 0183 data in low voltage. Which has never been received in standard NMEA listener circuits
  • Save NMEA 0183 data & Oscilloscope waveform in Micro-SD. Also, check the data on a PC
  • Generate NMEA 0183 data & also Pulse signal useful to test equipment, All while the vessel is anchoring
  • Supplied with a reliable rechargeable battery.


Additionally, the NMEA output feature is useful for testing suspect equipment that requires a NMEA 0183 data input. Once data has been monitored it can be stored on the internal storage. The data and waveform may then be analysed on a standard PC or laptop.
