I like all the features (and imminent hackability) of this power supply, but the numberpad layout absolutely kills it for me. If it was laid out more like the 1000 series power supplies, I'd be putting my order in for a $400 power supply today.
You can even see Dave have to hunt with his thumb when typing in values.
Dave.... I think the reason the main display lagged the set display was because the main display is an actual, measured readout. Have you tested how quickly it can jump from one voltage to another? The setpoint may be too heavily filtered in hardware to make it change as swiftly as you can adjust it with the knob in software - and if that's meant to be a true measurement, I'd prefer they didn't make it lie to me while I'm turning the knob just to make it look better.

I thought about that at first but looks more like an update-after-timeout type response. If you look you'll see that it doesn't change at all while he wheels then it snaps to the latest value. I like what someone said (I think a YouTube comment) about protecting the load if you pass the target voltage and "spring" back. The output would have never tracked and all will be well. I actually rather like that. Consider if you were adjusting the 1v place and overshot your destination by one or two volts. No problem because the output only tracks when you settle. Move slow and it always tracks which can be assumed you're being careful and want it to track with you. Just a guess but sounds good to me.

That would be absolutely horrendous.
If you know what voltage you want type it on the (weird) keypad. The knob is to find the voltage or current when something else happens, like a regulator dropping out or an over voltage trip point.
If the output doesn't track the knob in pretty much real time it may as well not have one.
For a moment I thought Dave had a guest presenter for this video. You sound a bit crook mate!
Hm...I have again the strange feeling,this video is just too commercial. Once again: "Look how Rigol is much better then its shitty competitors.. Since i have this PSU i got lots of chicks, better job, stronger erection and more self confidence. Buy this product and your life will be as never before...call now..." and so on.
For example this Voltage spike at the power on can kill your 100k$? Chip if you forgot to disconnect your board from PSU(which can happen very easily), and any overvoltage protection will help you.Moreover we dont know if this spike appears in some other situations....
But all this excitement and "sugar crust", and the last scene where you are leaning on this PSU, telling people it is the best on market and blabla...
I understand you have to make money from your videos, and you have to give positive feedback, otherwise anyone will pay you for negative advertisement, but it was just to obvious to me.

Having said that, I think your comment about Dave's comment that "for example this voltage spike could kill your $100k board" was interesting in light of the fact that the "non-review" was sailing nicely pretty much all the way through and then we got to the tests where we had what? Spikes. Just seems to me that if spikes could kill a $100k board that we should be vetting the spike issue a bit further. Not everyone has a $100k board but I doubt everyone wants to disconnect their device(s) before every PS power-up.
Same reply I gave to your same comment on Youtube:
Yes, i did. It was Tekway oscilloscope first impression video #487 . And then again you were comparing it to Rigol all the time, talking how much Rigol is better then this crap. Moreover you done lots of Rigol (positive) reviews before, that is why i am thinking Rigol is paying you for positive feedbacks (which is ok to me, since you have to earn money? somehow). I would glad to review Atten and Rigol PSU but i am not that rich to buy them.
Does it act as a DCV multimeter when the channels are off?
...So I'm calling you out:
Show me the evidence where the Rigol has the same signal integrity issues as that Tekway I tested.
I don't own Rigol, so i couldn't compare it to my Takeway.
Takeway is by far not the perfect scope, but it is excellent for its price. I wouldn't expect ideal signal integrity and super smooth operation from a 300 Euro scope.
But it does its job for hobby segment (the segment it is designed for) very good.
The bad things you mentioned about this Rigol PSU aren't killer issues, some buttons or colors you don't like,very subjective, who cares.If I would do a payed reviews, i would also point some light disadvantages , to make my video more credible... Else it would be too perfect.
It seems you don't have tolerance to negative feedback, i know people like that. They ask for feedback, but once you criticize their work, they go berserk on you.
