Hi Kanika,
Welcome as a new user of LabVIEW and NI high-speed digitizers! I strongly recommend reading the NI High-Speed Digitizers Getting Started Guide which contains all the information you need to install the driver software and get your hardware up and running. The latest version of the driver is NI-SCOPE 3.6 and can be downloaded at https://www.ni.com/en/support/downloads/drivers/download.ni-scope.html. It is important to make sure that this version will work with your operating system and your version of LabVIEW; if you have an older version of Windows or LabVIEW, you may need to look at installing an older version of NI-SCOPE.
In general, there are a couple of great resources to start with when using an NI high-speed digitizer and NI-SCOPE once the driver is installed. We actually provide a tool with the NI-SCOPE driver called the NI-SCOPE Soft Front Panel that is a stand-alone, interactive program allowing you to acquire, control, present, and analyze data with your NI 5105 digitizer. The program mimics the look of the front of a traditional oscilloscope, and can be seen in the image below. Note: for your particular device, since it has eight channels, you will be limited to only having controls visible for two channels at a time, but any channel can be selected from the channel drop-down list and controlled (you just can't see the controls for every channel at once).
To actually program the device in LabVIEW, we provide numerous shipping examples that will get installed to your computer when you install NI-SCOPE. The LabVIEW examples can be found through the LabVIEW Example Finder or in a folder under Start » Programs » National Instruments » NI-SCOPE » Examples » <LabVIEW>. For getting started, I would recommend the niScope EX Getting Started VI and the niScope EX Configured Acquisition VI. Depending on your application and what signal(s) you are measuring, you may need to examine some additional programs to see what will work best. However, these are the best resources for learning about the NI-SCOPE API and how the programming flow works for NI-SCOPE. As always, feel free to also browse ni.com for additional example programs that have been posted for accomplishing various specific tasks. The Getting Started Guide should contain all of this information and more, so definitely give it a browse. Hope this helps!
