ARG5410 MkII

EPIRB tester

Handheld beacon tester/receiver. Decodes transmitted message. Displays frequency and relative power level for 406MHz and 121.5MHz



Check the correct operation of EPIRB, ELT and PLB distress beacons COSPAS/SARSAT. The ARG5410 MKII EPIRB Test Set provides accurate, independent checks of the correct operation of COSPAS/SARSAT distress beacons, such as EPIRB, ELT and PLB’s. It can be connected directly through a suitable attenuator, or will receive the radiated signal using it’s own antenna. Radiated tests should be carried out using the beacons own self-test mode, if provided, or a screened room or enclosure. The unit comes complete with user friendly software, designed to guide the operator through the test procedures, with received signals decoded into plain English. Messages are time-tagged and stored, and can be viewed on the internal LCD display. Alternatively, by using the serial date output, date can be downloaded to a printer or PC.
