lock-in amplifier with USB-6221

[johndoe177]

Hi,

I was just wondering if it is possible to set up a lock-in amplifier with a USB-6221 DAQ system.

Thank you.

Hi johndoe117,

Because the USB-6221 does not have dedicated ADCs for each channel, it is not recommended that we try and implement a Lock-In Amplifier. I would recommend using one of the DSA cards instead. I have included a KnowledgeBase article below that details what we look for when we want to implement a Lock-In Amplifier for some further information you may find helpful.
