Expected attenuation with fc=20kHz (shielding + input filter + output filter) is 14 + 3 * (6 + 12) = 68 dB
Expected attenuation with fc=10kHz (shielding + input filter + output filter) is 14 + 4 * (6 + 12) = 86 dB
This noise will alias when the ADC runs at 20kHz.
Low-frequency gain of the differential polarimeter seems to be larger than the of SR570. It's unclear if it's a feature or a bug or a poor connection.
