Noise is one of the most important performance figures and typically given as SNR, Signal-to-Noise Ratio. This is a ratio of two separate measurements: high/maximum signal level and noise level without signal. In audio measurements, signals and noise are typically expressed in level instead of power. Thus, SNR(dB) = 20*log10(signal_level/noise ...

Audio Precision’s ATS-2 and 2700 series analyzers can make all of these measurements. SNR is available using a Quick launch macro, dynamic range measurements rely on the THD+N amplitude function meter, and noise in the presence of signal measurements can be made using our multi-tone analyzer.

Two-step equipment setup for measuring signal-to-noise ratio. Measuring SNR is a rather involved procedure, and the accuracy of the results depends on strict adherence to a set of rules. The following routine test procedure is suitable for measuring the SNR of an audio mixer:Step 1: Disable all inputs except the one in the measurement path.

Using traditional methods, SNR requires two measurements and a bit of arithmetic. First you measure the signal level, then turn off the generator (and often, terminate the DUT inputs in a low impedance as well, to fully reduce the noise in the device).
