Congratulations on the new scope, it will make the projects more enjoyable.

Thanks! Indeed, it will.

A genuine unboxing with no preparation, lol. Enjoyed watching you figure out how to adjust the function generator frequency after having the same experience myself when I first got it.

Yeah. I didn't look at any reviews, just fumbled my way through it. Learnt a few more things later. That's the fun of it!

I use a passive high quality attenuator ballanced XLR with short cables for the sig gen with no noticeable deterioration. Can pull it down to 50 mv RMS no probs.

good channel , i want buy one for my physic experiments

As I said in the video, this is a basic, cheap, entry-level 'scope. It does the job, but it's by no means "professional".

Hi Sir - are you content with the fnirsi 1014d? Have you encountered any shortcomings whilst testing or repairing projects?

Only having one channel trigger. Doesn't that mean that if you compare the input signal and the output signal of a circuit, only one of those traces will be stable? The other one will be rolling across the screen or bouncing around?

No, I actually found this to be fine. Both display fine. It's only if you monitor 2 different sources/types (eg one sine other square) that it doesn't trigger right.

Hi - Provided both input and output signal you measure have the same frequency, regardless of amplitude, you may set the trigger on any of the channels and the signals will be stable. As i said, the frequency of both signals must be the same, otherwise the signal which is not triggered, will bounce around

30Mhz, it had a sample memory of only 3000bytes, it does not display a signal below 35mV on the 100mV range. Sensitivity 100mV, overall bad software. Did I forget something?

The terrible quality of the rotary encoders? Each time you turn it off and then on again, it decreases the time base by one step...actually that's kind of a cute quirk. :-) I'm enjoying mine, but it really is a toy more than a tool.

You can get away with bending the parallel prongs to the Aussie angle if youre in a bind . Ive done it a few times with phone chargers .

So have I. I just don't like doing it, as sometimes it doesn't fit in the socket correctly. This can lead to accidentally contacting the prongs with your fingers when removing it, as these do not have "safety" insulation at the end of them.

Would this be adequate for testing tube amps?

With the right probes, yes. As this is isolated from the mains earth, it should be fine. Just be aware of the high voltages, use an isolation transformer and common sense.

@AstrosElectronicsLab thanks for the reply. I ordered one . I was wondering how high of a dc v can these handle
