Lock-in Amplifier

Post by aprasad8 » Tue May 09, 2017 8:06 pm

Hi all,

I have recently started using Red Pitaya in my lab for data acquisition. These days I am building a Lock-in Amplifier using Red Pitaya as a demodulator and reference signal source while using an input filter from Alligator Technologies (http://bit.ly/2qo106J).

I expect the high sampling rate of the Red Pitaya to outdo the bandwidth of most commercial Lock-in amplifiers from the likes of SRS and Signal recovery.

Will keep the thread updated as I progress.
