It might be helpful to clarify that since this is a voltage ratio, it's
20log rather than the 10log used for power (e.g., doubling voltage is
6dB, doubling power is 3dB), so the scaling will look different than a
typical spectrum analyzer. (It would be nice if the instrumentation
blocks could have an option to select voltage, or power into 50 or 75
ohms...)

This pops up a lot, and hence earned a spot on the FAQ a while back:

I just did so :)
