Lock-in Amplifier Moku's Lock-in Amplifier currently does not support phase unwrapping. While it can output phase as the error signal, the phase detector is limited to one cycle of dynamic range. This limitation arises because the effective range of the arctangent function is [-π, π]. When X changes sign, the Y/X ratio shifts from approximately -∞
