All measurements are performed on an IEC 60318-4 (formerly 60711) compliant setup. Frequency response settings: Sine-sweep Sequence length: 32k Sampling rate: 48,000Hz Output volume: generated to -10dB Log-frequency sweep 10 sample average -15dB/0dB/+15dB scaling CSD settings: dB range: 40 Maximum frequency: 20,000Hz FFT length: 1024 FFT block shift: 6 Maximum number of FFT blocks: 60 Apodizing window rise time: 3ms Start point: 2.500ms The rest of the settings should be default or self-explanatory. DISCLAIMER: Comparisons with measurements from other rigs are not recommended due to scaling, settings and/or minute physical differences affecting response. However, they are meant to follow the 318/711 standard so measurements should be more similar than different. Output impedance can be assumed to be <0.5ohm. This is all a learning process for me, so expect changes along the way. There are probably some things I'm doing wrong and I'll be diligent in seeking them out.
