Drapcho et al. [14] demonstrated a very elegant way of performing multifrequency PA measurements. Rather than using a PM waveform composed of the sum of several sinusoidal waves, they drove the phase-modulation mirrors with a square wave, as shown schematically in Figure 20.14. A square wave with frequency / hertz is composed of the odd harmonics of / ...
