Lock in Amplifier
Posted: Thu Apr 19, 2018 6:50 am
Hi all,
Just came a across a problem which needs a lock in amp, and my red pitaya is just sitting around waiting for a job. After little research i found, that some guys tried to implement a lock-in on the rp, but i havenĀ“t found any detailed description on how to do that.
3 things are coming up to my mind:
- an analog lock in
- a variant with gnuradio
- a fully digital one implemented on the red pitaya
Has anyone of you, in his or her life, came a across an affordable idea or solution within a frequency range of a few tens of kHz ?
any hints are appreciated
