SUS Noise Monitor

Design goals

  • No saturations as long as the coil driver input signals are at the 99th percentile or below.
  • Provide enough gain (at 20 Hz and above) to boost the DAC noise above ADC noise.

Design inputs

  • DAC noise model: page 6 of G1401399.

  • PUM coil driver transfer function. LISO models are available here.

  • The worst-case dewhitening state for the noise monitor is ACQ off, LP on.

  • ADC noise level, about 4 uV/rtHz. (Reference: T070213)

  • Coil driver input spectra, G1801540.
