I've been using the LockInDEMO.vi program from NI lock in amplifier start up kit. It seems that the signal and reference have to be either both external or both simulated(turn the signa generator switch on or off), but could it or some other programs use a simulated reference to perform lock in on an external signal(from my daq: PCI-6036E board)?
Another problem is that when I try to acquire data via programs using Daqmx, I always receive the following error message: Error -89130: Device is not Available for Routing.... This error doesn't disappear after I reset my Traditional NI-Daq in MAX(which is the only daq I see there I don't know whether I should also see another Daqmx driver I installed) as suggested by: http://digital.ni.com/public.nsf/allkb/61371556441E5FF68625730600775934
Any suggestions would help. Thanks!

Hi gyhe123,
How long have you been getting that -89130 error? Did you ever have it working? If so, what changes did you make near the time when it broke?

It hasn't work yet. I installed NI Daqmx driver 9.5 to use some VIs with Daqmx modules, but this error occured when using modules like Daqmx write, Daqmx read.

Sorry to hear that! Let's take a step back then, what are you trying to do overall, and what hardware exactly are you working with? Also could you explain a little more what you mean by "reference" in your first question?

I was trying to use modules from Daqmx driver to extract external signals from an NI Daq(BNC2120) connected to PCI-6036E board in my PC, and got stuck in that error.
However, using Traditional Daq modules I revised a VI to perform lock in with simulated signals as reference, and now it works fine.
The reference signal I mentioned is a signal with a clear frequency so that the lock in program use it to extract the corresponding frequency component from input signals.

Gotcha. Well glad you got it working!

Thank you! Although the Daqmx modules still malfunction

I researched the lock in amplified start up kit a bit more, and it appears that it has not been worked on for several years. If you are able to get it running through traditional daq modules, I would stick with that. I don't think it has been maintained through newer versions of DAQmx
