Not really. Digital is more common because it's just easier to use and read. when you go up in price, you can get all these features on digital ones that you cannot get on analog. I have both, and while i use my digital the majority of the time, the analog one works when, for any reason, I do not have my digital one.

Okay I'll go digital. I rarely need one so no need for two

I mean if I was testinga near 100MHz signal would the OWON be ok(it is only 500MS/s whereas the Fluke is 1.25 GS/s) Plus I could beusing a Fluke 190 204: 200 MHz with 4 channels and 2.5 GS/s?
Or would 100Mhz @ 500MS/s be adequate?

ShawnD1, that just means the reading will be incorrect. It will not bounce around as you described. I have a background in electronics and I have never seen a digital meter bounce around like you described from an inverter's output wave.

The meter I used to measure the inverter voltage in my Jeep was a Greenlee DM-20. Not only did it not bounce around, it was accurate.

Typically, a meter having trouble with the AC waveform will read quite a bit low, but it won't bounce around very much.

People have come to expect solid facts out of me. When other people say things like "torque wins races," it's up to guys like to me to keep it real and explain why that's the most retarded statement in the history of the universe.

error in digital multimeters:

Uh oh, I guess Agilent is in on the conspiracy as well. They too think this is a common problem!

Why did you make a post that proves my point though?

I told you to get a True RMS meter...

You didn't say anything like what you just posted... :rolleyes:

I love my analog scope:

now this is a nice one. Is this easy to use?

When I used my Walmart voltmeter to check inverter voltage, it bounces between 100 and 110. Actual RMS voltage is 120.

forget the multimeter.
What I need is an DSO preferably handheld. I will be working on RF mainly UHF. What do I need?

way to ask for one tool wait till 60+ responses and then change title to a completly diff tool. wow.

Hope your budget grew, by ALOT.

You changed your title to "oscilloscope" to make us look stupid.

lol @ handheld scope for $100
You will be lucky to get one for under $1000.

I am not even aware there are handheld osciloscopes.

When I left Tektronix we were working on brand new unit that could probably be held in one hand. Didnt have a lot of capability though.
And this was in the service depot, not the factory, so I know the things are out there in the world.

Avoid digital. Digital multimeters are total garbage. They simply don't work.

You can try this at home. Using a digital multimeter, try to measure the voltage coming out of an AC inverter. It will say 120, then 60, then 150, then 78, then 95, and it will keep jumping around.
Try the same thing with an analogue meter. It will go straight to 120v and stay there. No BS.

I see you are no electrician by trade... This is BS.

Not only do they have portable ones they have USB ones that can turn a PC screen into one. Heck you can even use the input of your sound card to use one to analyze low(er) frequency waveforms that are within its DAC bandwidth. :cool:

A scope for $100? You'll be lucky to find a busted 30 year old scope for that.

Your best bet will be to get one of the software scopes that you run from your computer. I think those are less than $1000.
