Daqmx

[Er.Rubak Kumar]

 When measuring a physical signal using LabVIEW and NI hardware, what is the correct path of the signal?

1. Sensor>Terminal Block>DAQ>LabVIEW
2. DAQ>Sensor>Terminal Block>LabVIEW
3. Terminal Block>LabVIEW>Sensor>DAQ
4. Sensor>DAQ>Terminal Block>LabVIEW

Why don't you talk to your fellow students?  I can't say that I understand the question, but I'll try to help you a little -- do a Web search for "Learn 10 Functions in NI-DAQmx and Handle 80% of your Data Acquisition Applications" (or, alternatively, load one of the many DAQmx examples that ship with LabVIEW) and look at the order of the functions and their relative positions on the (common) Error Wire.

What does your instructor mean by "Sensor", "Terminal Block", "DAQ", and "LabVIEW"?

Yeah the question was little un understandable.. then the daqmx alignment will be as the virtual, sample clock, start, Read/write, stop ... But here the questions they said that 

Which is the correct order for the signal to propagate through components when acquiring a signal?

A. Sensor>Terminal Block>DAQ>LabVIEW

B. DAQ>Sensor>Terminal Block>LabVIEW

C. Terminal Block>LabVIEW>Sensor>DAQ
D. Sensor>DAQ>Terminal Block>LabVIEW

In those options I have an dout in terminal block in my point of view my allignment will be 

Sensors, daq, terminal block, Labview 

But some frnds say that 

Sensors, terminal blocks,daq, labview 

What will be the correct one in those...

Thank you...

As I said, I don't know what your instructor meant by the terms "sensor", "terminal block", "DAQ", or "LabVIEW".  But I also pointed you to examples of LabVIEW code showing the use of LabVIEW code to do data acquisition (or data generation) -- all you need to do is look at "known good LabVIEW code" and figure out how to "order" the four terms, which were (presumably) defined by your instructor.  So you'll have to do the work of learning what your instructor means by these terms, and then look at the LabVIEW examples and figure out how to sequence them.

Option A: Sensor -> Terminal Block -> DAQ -> LabVIEW

Sensors generate the electrical signal
Terminal block (implicitly screw terminals) connects external signal wires into DAQ

DAQ is the hardware that converts the electrical signal into digital data

LabVIEW is the software that runs the data acquisition logic to acquire data from DAQ
