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.
