conditioning of the BPM
electrode signals with classical
analog and/or RF
techniques remains, to
adapt the signal levels and
modify the waveforms to
match the ADC operational
conditions. Also, the generation
of test or calibration
signals, necessary to ensure
long term reliability and
performance of the BPM
processor, requires some
traditional analog and RF
electronics.

a field-programmable-gate-array (FPGA). Today, most of the
BPM front-end hardware can be implemented on a so-called
" RF system-on-chip " (RFSoC), which integrates several ADCs,
DACs, FPGA, digital signal processing, memory, and control
functions on the single monolithic die. Still, some minimalistic
BPM Resolution
The resolution of a beam
position monitor, i.e., the
smallest detectable change
of the beam position is-
besides accuracy and
long-term stability (reproducibility)-the
most important performance parameter of a
BPM system. Both, BPM pickup and the following signal processor
defines the achievable BPM resolution.
Consider a broadband BPM, e.g., a pair of button electrodes
A and B. For small beam displacements we consider only the

ϕ = phase difference signal, Δt = time difference signal, ATN = arctan, log = logarithm base 10, POS = beam position.)
