I waited far too long to buy one of these portable oscilloscopes.
The FNIRSI 2C53T is $90 on Amazon: (Amazon affiliate link)

I’m guessing there’s not enough sample memory to get a whole cycle of 1Hz at whatever sampling rate the DDS signal generator uses?
I picked up one of these. Without looking it up I think I paid right around 50 bucks for it. I haven’t used an oscilloscope for so long I’ve forgotten how to. For that price it’s a no brainer to have one. I think it’s a really nice unit. I’m glad I have it.
Fkn YAY! You are the first in 10 reviewers who ACTUALLY PAID for the product you are reviewing. A gentleman and a scholar both.
Not a shill. Not an infomercial. Not a, “I got it for free but I’m unbiased and honest.”
A real life old school Youtuber reviewer. I thought your type were extinct.
That first scope is not giant. The one you are featuring is far too snall fir me but perhaps not you.
Temu sells a scope similar to this from Zoyi, model number 703. The price fluctuates between $60 and $70. Its controls are a little but more intuitive. I bought mine about half a year ago, and I’m happy with it. It’s nowhere near as good as the multi thousand dollar Tektronix one, but you can do a lot with it.
