Possible to detune linien locking?

[kongmunist]

Hello, we are getting an error signal on our SAS setup which Linien readily locks onto. However we are interested not in the zero signal, but in a small detune away from the zero signal to do Doppler cooling. I know this will probably be less stable than the zero-crossing lock, but I am curious if anyone has tried modifying the offset parameters to shift the lock away from center. Since the zero-crossing is preceded by a linear-ish region, I'm curious if a simple y-shift would shift the "zero" of the lock, allowing us to lock onto our desired offset.

Nevermind, found the offset button under demodulation!
