Deviation Accuracy
[1] External phase modulation deviates the phase of the carrier, applying the set deviation sensitivity to the modulation input signal.
[2] See chart showing maximum available equivalent frequency deviation and equivalent maximum frequency deviation for which
phase deviation accuracy specifications apply for sinusoidal inputs (φd = Fd / Fr). Applies to demodulated signal content at rate
frequency fundamental.
