sine wave signal onto the power bus, and the audio analyzer measures this ac voltage at the APA power pin and at the k V SVR V OUT ac S = 20log PSRR V V OUT dc S = 20log ∆ ∆ output. Here the analyzer, an Audio Precision System–II, is configured for a crosstalk measurement1, 2; it sweeps the ac voltage at constant amplitude over the audio band,
