Transmitter (Tx)

• Loop size:      314 or 494 m²
• Loop turns:   1 or 4, vertical axis
• Wave form:  trapezoid pulse
• Variable repetition frequency of 20 - 500 Hz
• Any repetition frequency can be selected as desired
• Dual transmitter mode (optional): e.g., 25 or 30 Hz (high moment) and 222 (low moment)
• The transmitter peak moment is up to 200 000 Am²
• Turn-off times vary from 6 µs to 70 µs depending on the moment

Receiver (Rx)    

• Digitally controlled analogue gates
• Central delay times from 10 µs to 10 ms - 10 gates per decade
• Each single transient decay signal is stored for further noise reduction during data processing

Mechanical

• Flight speed up to 110 km/h
• Preferred altitude 25-40 m (AGL)
• Power is supplied by a generator - no power is needed from the helicopter
• Total weight  ~ 450 kg
• The system is easily transported and mobilized
