Once they (rigol.eu) told me, bode plot will come - But nowadays I will only believe it when I can see it... --- Quote ---Scope off: The volume is about 30dB (noise in my room). Scope on: The volume is about 50dB. --- End quote --- I´ve measured the noise too. When I remember it right, it was +6dB additional to the enviromental noise. Measured with a calibrated microphone. |

Hallo Martin Where exactly did you measure? I positioned the microphone (Smartphone) on the backside of the oscilloscope (10cm near of fan side). |
| Martin72:
Appx 50cm, I thought it was more realistic. Last measure (last pic) I ´ve made with as short as possible distance. |
| rolfdegen:
I did a frequency analysis with and without my scope. The distance from microphone to the scope (backside) was approx. 50 cm. Without Scope With Scope If you hide the low frequencies below 100 Hz, than confirms your measurement of + 6dB(A) with scope :-+ Greetings from Wuppertal. Rolf |

Hi, Something I´ve forgotten: Measures were taken BEFORE the modifications were done by rigol. Should repeat it... Martin |
