NOTE: The node voltages given in the following table are approximate values based on a sample
of signal generators. Your signal generator may not reflect these exact values. Additionally,
the resolution of these values varies from node to node. As a guideline, interpret your
measurements based on the number of decimal places shown for the expected voltage.
