lock in amplifier reference frequency always 1

[mattk118]

Hello,

I am using the DAQmx lock-in amplifier software that was downloaded from NI and I am using the PXI-NI-4462 DAQ board.  I was testing the software by using two function generators to generate two different sine waves and sampling them with the 4462 on channels 1 and 2.  The issue I am seeing is that the reference frequency is always reported as 1Hz and this never changes with a change of the input reference sine wave.  Is there something I am missing?  Thanks for any help!

Are you using the NI Lock-In Amplifier Start-Up Kit downloaded from our website? If so, which of the VI's are you using for this example that you are testing as this will help us take a look at the issue? Also a screenshot of the problem that you are seeing would help us to better understand the issue, one for one frequency, and another at the second frequency of input.
