Hello, thanks. I have switched the DHO1074 off and on again. Now I have a credible 23 mVrms. Best regards egonotto |

Hello, it is 23 uVrms. Best regards egonotto |

Which means preamp is working really nice but ADC performance is not best in class for the BW. Or ADC has much wider BW than needed. Which would make sense if they used same ADC as in 800+MHz DHO4000... |

Here are a few noise measurements. --- End quote --- You don't use FFT to measure noise levels directly, use AC RMS measurement for that. FFT can used to measure signal to noise ratios, or maybe to look a noise characteristics. |
