"Popcorn" noise is a part of every high impedance silicon transducer, and the PS1 is no exception. The PS1 is very sensitive and applies a very large amplification on the signal, so the popcorn noise is visible in the raw trace.

Occasionally (once every 10-60 minutes) there is a brief 1-2 sample transient on a PS1 input channel. The expected voltage spike is ~100-500 mV. This translates into a brief increase in the demodulated signal up to ~2 mV.
