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.
