My main concern is that it might influence the accuracy of the measurements. I am probably going to try to reinstall the stock firmware on the scope and exchange it via amazon. --- End quote --- Why would it have influence on measurements? FW should have no influence on it. Also you need new FW for bug fixes.. That is a faint sound of ceramic capacitor or a coil in switcher on board. When scope is doing sweeps it changes current consumption and modulates the sound. There is good chance all of them make that sound or all the ones in a single manufacturing batch do. Is it really that annoying it warrants return? You night return it and get replacement on with same sound. |

Yes, I know that the FW has no influence on it since the sound was present before I installed the new FW. I was mentioning that I need to put the factory FW back on if I wanted to return it. I am weary of any kind of sound coming from the power supply and I am worried that it might contribute to different or common mode noise that can influence the accuracy of the measurements. It is also very annoying to hear. I primarily wanted to post to see if anybody else has that issue. |
