Outdoor characterization bench of antennas

Valentine antenna array on a turntable

Principle :

Transient response measurements of the antenna under test,

Time window of the useful pulses,
Calculation of antenna characteristics from the useful signals Fourier Transform (radiation pattern, gain)

Elements of the test bench:

Pulse generators (max output voltage 220V, rise time 120ps)
Digital serial analyzer sampling oscilloscope 20GHz
Real time sampling oscilloscope 8GHz
UWB components: probes, attenuators, power dividers, delay lines …
Turntable driven by a controller using GPIB protocol
Broadband reference antennas (XLIM design)
