WebbThe noise generator produces a band-limited Gaussian signal of the appropriate bandwidth and power. In the first step of the NPR test this signal is fed directly to the A/D converter input, where it is quantized and then reconverted to analog by a high-speed D/A. The D/A must itself be sufficiently low in noise so as to not corrupt the results. Webb@User968243 The theoretical noise floor of -174dBm per Hz is for 50 ohm systems at room temperature.
