How to output and acquisite signals simultaneously

Solved!
Go to solution
hello everyone I am using NI PCI-6110 card, I want to achieve signal output and acquisition by this card .A is PZT 1 , B is PZT 2. A is the excitation source, frequency is 30KHz,the voltage is ±10v, B is the receiving source, the voltage is about tens of mv. The distance of AB is 120mm, the propagation time is about tens of us, how do I want to measure the time of propagation, regards wys

Hi wys,

 

how do I want to measure the time of propagation

  • you should sync both DAQmx tasks (There are example VIs in the example finder explaining how to do this!)
  • use AutoCleanup…
  • set meaningful default values in your controls instead of writing them next to the controls…
  • don't set the buffer size at DAQmxTiming when you select "Continuous" sampling mode… (Read the LabVIEW help for this function!)

 

 

Best regards,

hello 

GerdW

  I am appreciated for your advice, according your advice I revised my procedure, I used my Oscilloscope to test AO, it ok. but I can’t get signal from AI , could you tell me why? In addition, are they the same between The name of local terminal and the name of the physical channel in Get Full Terminal Name1.VI ,if not ,why

Best regards,
