Lock-in amplification (1f and 2f simultaneously)

[colapili]

Hello everyone,

I am currently in an internship about frequency modulation spectroscopy. I would like to have a lock-in detection on labview. The objectiv is to obtain signals 1f and 2f simultaneously in a simple manner. I'am a beginner on labview and the internship is relatively short... Can someone help me ? 

Thank you in advance for your answer.

Hi Colapili,

I guess it will probably depend on the hardware you are using. But I could find some examples on the links below :

If you are using DAQ devices :
