I don't think anybody's said this yet. Fo is used to signify the dc component of the waveform. If a square wave switches from 0 to 5V, with a 50% duty cycle, Fo = 2.5V. F1 is the fundamental (1GHz in your example), F2 the second harmonic etc. The term 'first harmonic' is really a bit confusing, and 'the fundamental' is better.
