 |
|
I recklessly and naively recommended someone get one of the cheap
handheld digital o'scopes to help troubleshoot alternator issues.
He got an FNIRSI 2C53P (not cheap but includes a multimeter and signal
generator and is 2-channel).
When he reported trouble with displaying a good signal (we're talking
12V DC plus 20 to 3,000Hz signals here) I started watching youtube
reviews and found there are settings where scope displays garbage. I
started looking at other similar scope reviews and found that it seems
to be a common issue that you can't trust what you see on them.
So here is the question: have any of you bought a low-cost (< $100)
handheld digital o'scope that's trustworthy?
Brand? Model?

Hi Finn
I've been using the "pico scope" 2000 series out of the UK.
https://www.picotech.com/oscilloscope/2000/picoscope-2000-overview
This requires a PC (laptop) but I find the extra expense (above the $100 mark) and the additional hardware (the PC) but the functions and capability are exceptional.
The price from their entry level on up is mostly limited to your application (and budget) and I've never been disappointed by the software in either performance or ease of use.
