Hand held Oscilloscope

[Mark-VA]

Okay, tech guys and gals, would this be a good scope/tester to have?

Knowing how much I like to measure frequencies.

It's almost halved in price - probably has a sales problem due to the low sensitivity - 20mV/div , but it works for your purposes

Any is better than none.

What all would - 20mV/div affect if I used the unit for other than detector frequencies?

Keep in mind this is a DMM with a little bit of oscope functionality added. Depending on what you want to do it may be enough, but I would not expect it to perform like a real oscope. 20mV/div is the maximum sensitivity, again it all depends on what you want to do. I rarely use a higher sensitive setting, but just recently I needed 10mV/div with 256x averaging to look at a response. If all you want to do is measure frequencies and see what a waveform looks like, this might be all you need.

Lord have mercy, there are many different hand held scopes on the market. I'm sure some are not so good and others well who knows.

I am happy with this one, 1 channel, 2mV, DSO112A

[Mark-VA]

Have you tried to scope metal detectors for transmit frequencies?

[pito]

it is good for frequency measurement, for coil nulling ....

I have the same one, I feed it with 4 pieces of 18650 in parallel. yes - it works, it's not complete garbage, but it's garbage
