Initial Test Procedure

  1. Turn on the function generator and the multimeter. Configure the multimeter to measure voltage (AC).
  2. Connect the multimeter to the function generator.
  3. On the Frequency Response VI Front Panel: set the High frequency to 10MHz and the Low frequency to 1 Hz. Set the number of steps to 10. Select Run in the Operate menu.
  4. As the VI executes, note the displays on the front panel of the function generator and the multimeter. You should see the frequency displayed on the function generator increasing as well as changing values measured by the multimeter.

Once the VI has completed its execution, something similar to a white horizontal line should appear on both plots with an amplitude on the semi-log plot and dB on the log-log (Bode) plot.
Both the semi-log and log-log plots include graph cursors to aid determination of particular frequencies. Graph cursor indicators and controls are shown below each of the plots. If the cursor is not visible on the plot, place the hand icon on the cross-hair symbol to the right of the cursor indicators, press the left mouse button, and select Move Into View. Move the cursor so that the vertical line is at 1000. Press the cross-hair symbol and select Goto Cursor. This will zoom in on the cursor's position which can aid in determining frequencies.
