Variable attenuators on four parallel analog chains are used to adapt the input signal to the proper level. The signal processing chain on the units are composed of analog signal processing, digitalization for fast ADCs and digital signal processing. Each channel consists of a digital down-converter (DDC), which is followed by parallel processing in wideband and narrowband paths.

Beam position is calculated using the following equation:

X = kx((Va+Vd)-(Vb+Vc))/∑ - Xoffset
Y = ky((Va+Vb)-(Vc+Vd))/∑ - Yoffset

∑ = Va+Vb+Vc+Vd

 

 

 

Data Paths

The Libera Brilliance+ provide several data paths at different sampling rates with different bandwidth and resolution.
Acquisitions can be done simultaneously on all four major data paths (ADC raw data, turn-by-turn data, fast acquisition and slow acquisition data). Fast acquisition data is available over SFP slots using Gigabit Ethernet Protocol.
