Aquiring a signal using a PCI 6251

[yed1920]

Hello,

     I am trying to write a program that aquires a signal from a device connected to a PCI 6251. The device attached to the PCI is an esophageal lead and it is suppose to read a sine wave being sent through the body. Then I want to filter the signal and send it to a buffer. I do not have a good programming background, and I do not know if I can use LabView Signal Express or a function with in LabView 8.2 to aquire the signal. Any suggestions as to what I should do? Thank you.

Hi yed1920,

There are a few ways to acquire the sine wave. You can use a single DAQmx Acquire Step in LabVIEW SignalExpress and this will allow you to configure the acquistion and view the incoming data. You can check out some examples using DAQmx in LabVIEW SignalExpress which are found at C:\Program Files\National Instruments\SignalExpress\Examples\DAQmx on a Windows system. The LabVIEW SignalExpress Help and the LabVIEW SignalExpress Getting Started Guide which are installed with the program may also give you some direction.

If you choose to use LabVIEW, there are examples which can help you get started. The Example Finder can be accessed through the Help menu. The DAQmx examples can be found browsing by task under Hardware Input and Output » DAQmx. You can check out the NI-DAQmx Help file or the articles found on this page to learn more about certain functions in detail.
