Power Supply Plants - Measurement Tasks

Measure and record field strengths to establish proof of emission levels to customers and authorities.

Frequency range

16 2/3 Hz (railroad), 50 Hz, 60 Hz


Transmission installation on HF masts / towers - Measurement Tasks

For transmission equipment on masts / towers, personal monitors are recommended.

Frequency Range

30 MHz ... 5 GHz


Power Supply Plants - Measurement Tasks

Prove safety for personnel, magnetic fields can interfere with safety or IT plants and systems.

Frequency Range

16 2/3 Hz, 50 Hz, 60 Hz, 400 Hz (ships, aircraft)


Communication Systems - Measurement Tasks

The railway's own communication systems have to be certified with appropriate HF measurement technology and checked regularly.

Frequency Range

30 MHz ... 3 GHz
