BEACON Tester

Technical Specifications

The Beacon Tester 406 02 allows to perform:

• Reception, demodulation and decoding of the emergency information transmitted on channel 406 MHz;
• Frequency measurement of 406 MHz signal in the range of 406.020…406.040 MHz, with accuracy to ±500 Hz;
• Audio-control of the sweep 121.5 MHz signal presence in the range of 121500 ±10 kHz;
• Power level measurement on 406 MHz channel within the range 19 – 43 dBm or 0.08W - 20W, with accuracy to ±3.0dB by means of antenna and ±0.5 dB by means of attenuator;
• Power level measurement on 121.5 MHz channel within the range 13 – 20 dBm or 20-100mW, with accuracy to ±3.0 dB by means of antenna and ±0.5 dB by means of attenuator;
• Estimation of the positive/negative phase deviation of modulated signal, with accuracy to ±2.8о;
• Measurement of total transmission time of 406 MHz signal, with accuracy to ±0.2%;
• Measurement of  unmodulated carrier duration of 406 MHz signal;
• Estimation of the equivalent radiated power of 406 MHz signal through broadcast.

The tester is designed to operate at the temperature range from 0°С to + 45°С and relative air humidity should be no more than 95%, which is determined by used LCD.

The tester power supply is performed by four AA batteries 1.5V, as well as by external DC source with voltage 4.5…7V and load current no less than 300мА. The tester is power supplied by USB cable when connected to computer or net USB adapter.

Approximate continuous operation time of the tester from the internal power supply elements is about 6 hours.
