The GMDSS Tester MRTS-7M is specified equipment for radio inspectors performing mandatory, periodical surveys of ship-borne communication equipment.

The Marine Radio Test System MRTS-7M allows ensuring the GMDSS equipment meets the appropriate performance requirements.

Specification / Features

MRTS-7M supports testing of the following equipment:

1. VHF receiver-transmitters

  • operation tests on any simplex channel including 6, 13 and 16 channels;
  • measurement of frequency and frequency deviation;
  • measurement of output and reflected power;

2. VHF receiver-transmitters with DSC

  • test of correct transmission/reception of DSC messages by means of transmission/reception of selective Test call to particular MMSI number and Distress (to all ships) messages
  • check the MMSI code programmed in equipment without any broadcast emission
  • measurement of frequency and frequency deviation
  • measurement of output and reflected power

3. MF/HF radiotelephone equipment

  • operation tests by means transmission/reception of modulated signal
  • measurement of frequency in range (1600 – 30000) kHz
  • measurement of output power

4. MF/HF radiotelephone equipment with DSC

  • test of correct transmission/reception of DSC messages by means of transmission/reception of selective Test call to particular MMSI number and Distress (to all ships) messages on any of 6 distress channels
  • check the MMSI code programmed in equipment
  • measurement of frequency and frequency deviation
  • measurement of output power

5. NAVTEX equipment

  • operation tests by means of sending one of two available test messages on any of three frequencies: 490 kHz, 518 kHz or 4209.5 kHz

6. VHF equipment of duplex radiotelephony with airplanes including operating on 121.5MHz and 123,1MHz

  • operation tests by transmission/reception of modulated signal
  • frequency and power level measurements

7. VHF radiotelephone stations operating in range (300 - 337) MHz (intended for river-sea vessels)

  • operation tests by transmission/reception of modulated signal
  • frequency and power level measurements.

8. MRTS-7M can be used as RF Signal Generator

  • device allows to generate the RF signals in range of 0,5 – 30 MHz

9. MRTS-7M can be used as RF Signal GeneratorFrequency meter

  • device allows to measure the signal frequency in range 0,5 – 30 MHz and 156 – 163 MHz.

10. The tester is capable to transmit and receive the signal by:

  • broadcast antenna
  • direct connection by means of attenuator and cables

Connection to PC

GMDSS Tester MRTS-7M can be easily connected to any PC or laptop to process measured results and create test reports/shore-based maintanence certificates.

The device can be connected by means of standard USB A -USB B cable. Special software is avaliable for download. FTDI driver should be installed for proper connection on first run.

The minimal requirements are Microsoft OS and a USB port. No extra hardware configuration is required.
