Problem with Continuous Swept-Sine Measurements(DAQmx) From Sound and Vibrations toolkit

Dear All,

 

I am writing to ask for information or guidance regarding the use of the Continuous Swept-Sine Measurements (DAQmx) example from the Sound and Vibrations toolkit.  I am using LabView 2023 Q3(64 bits) in Windows and we have in the lab a PXI system with the 4065 (DMM),5142 (Digital Scope) and 5412 (Waveform Generator) modules. We also have different USB-6212 DAQs. We have different lab practices where we must study the frequency response of different devices and also study their respective spectrum. In the past, we used signal express scripts to do this task, but they are outdated now and don't work anymore. Thus, I tried to create my own continuous swept-sine script with the 6212 DAQ, it works until some extent, but we are obtaining much noise, and it crashes continuously (maybe due to my lack of expertise in LabView programming). Thus, for this semester I have decided to try the Continuous Swept-Sine Measurements (DAQmx) example which matches perfectly what we want to do with. Before to try it, I read the device list requirements and none of the devices I mentioned previously are listed. Effectively, I obtained an error that is attached here, I can try to debug the problem, but I am afraid that it will end up being a hardware issue. In this regard, I would like to ask for any advice/suggestion to modify this script for my hardware devices or continue developing my own script. 

 

Thanks in advance for your help,
