Experiment A. Add Analog Input to Your VI 1. Follow the instructions on pages 3-6 to 3-7 in the Getting Started with LabVIEWguide to add analog input to yourname_lab1_ex1c.vi. • Instep, use the Operating tool and select ACH0 from the pull-down menu. 2. Click on File>>Save As and save this latest version of your VI as yourname_lab1_ex2a.vi to your ECI account. When you run the VI in Figure 3, the chart will show (somewhat random) input voltage noise. This is because you have not provided your DAQ board with a specific input. The hardware configuration for sampling an analog voltage signal is shown in Figure 4. To view a specific analog input, you connect an external voltage signal to the CB-68LP connector block shown in Figure 5. The connector block is directly connected to the DAQ (data acquisition) board by a 2 meter, shielded IO (input/output) cable. You will use the Tektronix CFG280 Function Generator to generate an external voltage signal, which you will verify on the oscilloscope before connecting to the connector block.
