Hi just curious, is there any USB device out there that can measure the RMS and P-P value of a usb power supply noise, down to the 1mV resolution, without using an expensive oscilloscope? The measurements made by HKJ is always using a high-end oscilloscope. Was wondering is there is other ways to determine the noise of power supplies?

sorry, we don’t have

RD DPS5015 Step-down Power Supply
[Delivery two weeks. Packed soundly, nothing crumpled on the way. It’s going nowhere easier, two identical cables, where to insert it is signed, you will not confuse. Works good. There are all the necessary protections: temperature, polarity. Various settings are set in the menu. The control is carried out by an encoder, convenient intuitive control. Even a child will understand. Even in this case, there is protection against children, which is turned on by a long press on the encoder knob. For my money, I think a very worthy device. The seller is sociable, quickly responds to SMS, answers all questions. Thank.]
