AITS-R - AIS Installation Test Set

The AITS-R operates on AIS1 (ch87B), AIS2(ch88B) and DSC(ch70) in accordance with IMO MSC.1/Circ.1252, “Guidelines on annual testing of the Automatic Identification System (AIS)”. Functions include AIS VDL / DSC evaluation, Pilot Plug evaluation and NMEA/RS422 external sensor terminal display. No GPS is required. Designed to test AIS Class A, Receivers, Class B, Base Station, AtoN, SAR and SART. Test data can be saved in the AITS-R's non volatile memory. This data can be downloaded to and saved on your computer afterwards. Test reports can be generated. It is a conveniently sized battery operated (re-chargeable) hand held unit. The AITS-R is used worldwide by radio surveyors, installers, developers and manufacturers. Factory Performance Verification (calibration) is done free of charge, conditions apply.

Features:

♦  Fully portable with internal battery pack (rechargeable) ♦  LCD display and keypad, menu driven command set ♦  Operational performance test on AIS1, AIS2 and DSC (chnl 70) ♦  In-line forward power and return loss measurement within a 26.667 ms period ♦  Termaline RF power meter, peak and average readings (1 – 12.5W) ♦  On-air interrogation of AIS equipment under test using keypad, including DSC ♦  On-air decoding and display of AIS received packets, including DSC ♦  NMEA/RS422 terminal display of external sensor inputs ♦  Pilot Plug evaluation function (NMEA/RS422) ♦  Selectable non-volatile memory retains test session for processing ♦  Download test results to PC and print customized reports in HTML format ♦  Internal battery and charging circuit or external 12VDC operation ♦  AITS-R operational & technical manual and software simulator provided ♦  AIS Development Studio (ADS) software utility provided ♦  Accessories included:    ◊  Antenna (helical / rubber duck)    ◊  Vehicular charging cable (12VDC)    ◊  RS232 Interface cable    ◊  RS422 Interface cable with crocodile clips (Pilot / Presentation / Sensor Ports)    ◊  TNC - BNC terminated RF cable    ◊  Programming Dongle (required for firmware upgrade) ♦  External power supply (battery eliminator) is not included (110/220VAC to 12VDC@ 500mA)
