Daq-mx lock-in amplifier

[sadeghi]

I'm trying to use labview implemented Lock-In-Amplifier but the full version listed on 

http://digital.ni.com/express.nsf/bycode/lockin?opendocument&lang=en&node=seminar_US

uses traditional daq which in unfortunately not supported on the 64 bit platform (I got an error trying install it on a 64 bit windows 7 machine)

There is thankfully a DAQmx version available but only for the simplified version of the software.

Is there anyway to post the full LIA with the DAQmx or let me know if it's possible to install legacy daq on my 64 bit machine?

Thanks,

Sam

Hi sadeghi,

You are correct that the Traditional NI-DAQ drivers will not be supported on a Windows 7 64 bit machine. I'm not sure how much searching around you have done on this topic, but the contents of this Lock-in Amplifier and DAQmx Discussion Forum thread may be helpful for you. Is the DAQmx version that you found this Multi Channel Count Lock-In Amplifier with NI-4472 and DAQmx example?

Thanks,

Thanks for the reply Matt,

Yes that is the example I'm using. I ended up using this simpler daq-mx example in my VI.

Also as a side note, I had a big problem initially with my PLL not being able to lock into the generated signal's frequency. I checked everything and finally realized the problem was with the PLL program not converting properly in LV 2010. I had to copy the sub-vi from an older version that I had on another computer for it to work.
