 AIS Tester is a test device operating on AIS1 (ch87B), AIS2(ch88B) and DSC(ch70) frequencies. The tester is designed under corresponding standards and recommendations as a tool of operation and installation tests of AIS unit (Automatic Identification System). The tests’ volume comply with “Guidelines on annual testing of the AIS unit MSC.1/Circ.1252”.
Tester does not use a GPS for synchronization. A proprietary TDMA slot-synchronizing algorithm is used which does not require a GPS 1 pps. It uses RATDMA for generating VDL and interrogation messages. A Pilot Plug evaluation function and NMEA/RS422 terminal display of external sensor inputs is provided. |

 The BEACON Tester is designed to decode and display the encoded message from a 406 MHz Cospas-Sarsat Emergency Position Indicating Radio Transmitter. The tester can be connected directly to the EPIRB or monitored "over the air" using the supplied whip antenna. The tester will decode any 406 MHz aviation protocol for EPIRB's.
A complete measurement solution. Measures all Cospas-Sarsat frequency channels and decodes all Cospas-Sarsat protocols. Measures 406 MHz parameters, 121.5 MHz parameters modulation, and the in-band 406 MHz frequency spectrum. The beacon industry is demanding higher quality from 406 beacons and is implementing more thorough periodic testing. EPIRB Testers that only decode the 406 message are not suitable to meet the increasing demands from the industry to ensure the beacons are indeed operating properly. The EPIRB Tester provides thorough beacon measurement capabilities. |

| The SART Tester is designed for check of any SART in accordance with the requirements of SOLAS - 74/88, and the Russian Marine Register rules M.628-2.
The SART Tester allows to:
- measure the carrier frecuency of response in range of 9140...9560 MHz;
- measure the duration of response in range of 50...150 microseconds;
- indicate the power level in range of 300...950 mW;
- calculate the quantity of sweep frecuency points in the response;
- control the power supply voltage with displaying on LCD;
- print the full protocol of the device test |

 | According to requirements of Maritime Administrations, there is a necessity for next inspections of EPIRBs after receiving of type approval. The problem is a complexity of the basic beacon signal parameters, which could not be measured with the simplified handheld testers. The most complicated for measuring and the most important for reliable communication to satellite and accurate position calculation are the frequency stability and phase modulation parameters. As a rule they require specially designed equipment in addition to standard measurement instruments (spectrum analyzer, frequency counter, etc.) which are not usually available on a ship board.
Beacon tester BT611 allows to perform not only control tests, but comparing evaluation of different EPIRBs parameters, too.
