Made in collaboration with Western University of Applied Sciences (Prof. M. Rubinstein) and Wavemind
Overall Frequency Bandwidth: DC-10 MHz
Specifications:
1. General
The system is composed by:
- An electric field flat plate antenna
- A magnetic field double-loop antenna
- Low noise analog integration and amplification
- 10 bits A/D and D/A conversion
- Data transmission via optical fiber link
- BNC outputs for scope visualization
- Battery supply option available
- Calibration input
2. Input signal conditioning stage:
- Input protection against overvoltages (spark gap)
- Input impedances: low impedance (50 Ù) for electric field signal and high impedance (1 MÙ) for magnetic field signal
- Time constant of the integration > 1ms
- Four levels of gain (remote selection)
- Pre-filtering (anti-aliasing)
- Frequency sampling: 25 MHz
