@@huypixeltft6068 What do mean by reverse phase? Are you talking about reverse polarity? What is this for, audio, stepper motor control, 3-phase motor control?
@@huypixeltft6068 Yes, it can do that. Any 2-channel oscilloscope can do that. I have a busy schedule and would not be able to get a video showing that in the near future, but you can take my word for it.
Nice unit, very similar to the ZOYI ZT-703S which I have and I know so do you. I think you may get some better results if you had taken the time to null out the test leads. On the Zoyi you briefly press the power button I would guess that there is a similar button on the FNIRSI . Like yourself I started with a second hand Heathkit. They did the job at the time. I agree that these little units are a fantastic tool for the new user, and also for those of us that are somewhat longer in the tooth.I bought the ZOYI for pretty much the reason you gave and that was working on MCU projects when away from my main workbench. However one other benefit that I bought the unit for was that it is completely isolated so you can do a bit of poking around on some older equipment without the danger of frying the front end of your scope via some earth return issue. Looking forward the the PSU project. Thanks for some very interesting videos, hope you had a Great Christmas, and all the best for the new year. Andy
Actually, I don't have the Zoyi. I have a Zeeweii DSO3D12 though. The manual for the Fnirsi is lacking quite a bit. I'll look around for a REL button as you suggest. Thanks for suggesting it.
I wouldn't call it crap. Not everyone can afford $1000 for a scope, DMM and FG (and that's already on the cheap side). Tools like this help get someone with less than $100 into the game.
The "eevblog" meterts always make me laugh. I just could never buy one. Not from Dave - he thinks 911 was an "inside job". Weird. I'll keep my Fluke 87-5.
LOL! I wanted a Brymen and I only bought it because I like blue better than red. Agreed, Dave is more than a bit of a right-wing conspiracy theorist guy. Sometimes it quite entertaining.

Can the device measure 2 reverse-phase waves on 2 channels?
Yes. The two channels are completely independent and will display whatever signal is present.
@@uni-byte can you make a video to measure 2 reverse-phase signals on 2 channels? I really need it

@@uni-byte I want to create 2 reverse phase waves to connect to the 2 input signal of the differential amplifier

@@uni-byte sorry, must be another channel - these things get everywhere...the Zeeweii DSO3D12 is another example of a nice starter instrument as well.
@@andye2005 Indeed it is.
They keep pushing out crap into the market.
