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?

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.]

RD AT35 USB 3.0 multimeter
[Delivered to Croatia in 2 weeks. USB meter has beautiful display and is very practical and easy to use, comes in a nice plastic box with foam which is great for storing and carrying around. USB load meter is nicely put together, and is also easy to use. I would suggest putting better plastic standoff legs and perhaps knob on a potentiometer. Also foamy box so that it doesnt flap inside. Overall, very nice products for amateurs and pros. I will order more in future. Love this seller and their products.]

RD DPS5020 Constant voltage current DC- DC Step-down communication Power Supply
[I liked the device, for a long time "lay" in "My wishes." So far, it has shaken by about 250 - 280 watts, although it is possible up to 1000 watts. There is no more power supply yet. All the declared parameters work, on the bluetooth of the device it connected without problems to a smartphone and laptop. By USB, too, no problem. A small minus, in my opinion, is a constantly noisy case fan. I can recommend a great device! I ordered the maximum configuration of the DPS5020.]
