Don't Fall Into This Output Impedance Trap!
Function Gen says 1V, Scope says 2V. Which one's right?

The function generator is set to have a 1 V output, but the oscilloscope measures a 2 Volt signal. Why? When set to 50 ohm mode, the function generator actually outputs double the specified input voltage. It does this because it expects to see a 50 ohm load on the output, creating a 50/50 voltage divider circuit.
