Electromagnetic Amplifier: PH300147


Electromagnetic Amplifier detects electromagnetic waves emitted by lightning discharge and integrates/amplifies the signals. It is composed of an input amplifier and an integrating amplifier with a broad frequency bandwidth of 1kHz - 10MHz. It can also be used as an instrument in analyzing electromagnetic waves generated by lightning discharge. It is a lightning electromagnetic field integrating amplifier with excellent maximum receiver sensitivities (15V/m for electric fields and 50nT for magnetic fields). The integrating amplifier has 2 channels each for for electric and for magnetic fields.
