Hi,
I am Chan. Recently, i have bought a NI card (PCI 6120) to do my soil testing research. I need this card to generate (voltage output) continuous sine wave to piezoelectric (transmitter) and then record (voltage input) the signal from piezoelectric (transmitter and receiver). This mean the NI card (PCI 6120) has to generate 1 output signal and get 2 input signal. All the signal are in voltage. The piezoeletric is penetrated into a soil sample. I would like to study the wave signal travel in the soil sample from transmitter to receiver.
I did try using the NI card to generate a continuous sine wave and record it using a PicoScope oscilloscope to record the signal. But, the signal is not smooth and look like a staircase.
I need your help to write me a labview (vi) to generate (1 output) the continuous sine wave signal (maximum 5000 Hz) and record the signal (2 input) (like oscilloscope). Then, i need this record data for my analysis. Labview is new software for me, therefore i need time to study it. But, now i need the (vi) to run my soil testing test first. I do wish to have more time to learn. I do appreciate your help. Thank you. Best wishes.
