Experiment C. Add Analysis and File IO to Your VI In this experiment, you will average the random data points you have collected and save your data to a spreadsheet file. Your VI will look like Figure 3. 1. Follow the instructions on pages 2-9 to 2-10 of the Getting Started with LabVIEW guide but save data.txt to your ECI account and your VI according to step 2 below. 2. Click on File>>Save As and save this latest version of your VI as yourname_lab1_ex1c.vi to your ECI account. Figure 3. Random Number Plotter VI with data analysis and file IO. PART 2. USING LABVIEW WITH DATA ACQUISITION HARDWARE Objective • To build a VI that acquires data from the DAQ (data acquisition) board, plots the data to a chart, analyzes the data, and writes the data to a file. In this experiment, you will replace the Random Number function in the Random Number Plotter VI with an analog input VI to acquire data from your DAQ (data acquisition) board, which resides in the computer tower. Analog Input Channel 0 (ACH0) on the DAQ board has already been configured to accept voltage signals in the range –10 V to +10 V. 1 The PCI-6024E DAQ Board has sixteen bit analog input channels, each with a maximum sampling rate of 200 kS/s.
