/diy/ - Do It Yourself

just add 50 bucks more and get the rigol
or try finding a used one on ebay

>>1824315
Should I go more channels at 50mhz or less channels and more ranger at 200mhz?

>>1824331
All of the above

>>1824331
OP, most cheap-tier Rigol scopes can be hacked to enable higher BW

>>1824406
>higher BW
Oh... great to know, I'm buying more than I need at this moment probably anyhow.

Get an Analog discovery. As long as you i don't mind using a laptop for it, it is the best for that price range.

>>1824484
>280$
>100MSa/s
>best for that price range
lmao
a Rigol DS1052E has TEN times the sampling rate, is a proper scope - no USB rubbish, and costs about the same.

>>1824310

Is that keysight in the corner really 211$? Where the hell are you getting those deals at?

>>1824310
If you're not doing class iv voltages you can save more. But then you already knew that, seeing how you mastered the secrets I'd gravity and all.

>looking for cheap used storage scope
>cheapest I can find is €150
>check on the internet if it's any good
>Dave found the same model for 19 aussiedollars
Apparently scopes grow on trees down there.

>>1824496
It's true, but you don't get the digital input/output, bus analyser, signal generator, voltage source, fft and spectrum analysis, full scripting and i'm probably forgetting something.

>>1824969
It does have FFT. You can also hook it up to a PC for scripting - even has sigrok support.

>>1824556
>secrets I'd gravity and all.
be dismissive all you like. I'm following my passion, I'm asking for help on tech equipment. How being a smartass cunt working for you?

>>1824675

I feel ya man, when i decided to get a scope, the best deal i managed to get in that price range was a TDS220 with a broken screen and missing knobs. The type of scope Dave dragged through the mud in a marathon for shits and giggles... He also gets quadcore i7 workstations in the dumpster for free, it's not fair

>>1824502
>Where the hell are you getting those deals at?

That was Amazon.

https://www.tequipment.net/rigol/oscilloscopes/digital-oscilloscopes/#/rigol/oscilloscopes/digital-oscilloscopes/?F_Sort=3

Which is the good deal or just pick any?

>>1825070
I also don't have any probes.

>>1825070
Is lower rise time better? I would think so.

Rise Time: 1.75 ns

>>1825074
My last in this price offerings.

>>1825136
it's an interface, not a scope.

I'm asking myself the same question, is this UNI-T 50mhz one ok? It's for strictly hobby use.

>>1825595
>UNI-T 50mhz one ok? It's for strictly hobby use.

Yes, is probably the answer. This thread was helpful, I'm going to start with a budget 3-4 channel. Then upgrade if ever.

>>1824310
my company purchased the hantek pc oscilloscope USB for us controls techs. still haven't broken mine out of the box yet.

I got this one 100mhz 1 GSa/s

>>1825615
>I got this one 100mhz 1 GSa/s
Thank you.

I wonder, do some have good training for newbies?

He's smitten with the scope, maybe I will be too, especially since I don't have much scope time.

He's a good presenter also.

>>1824310

It's a waste of my time at this moment.

>>1825708
nice.

I'll be making stuff like this also.

Op, if you don't know exactly what you need from an oscilloscope, you don't need an oscilloscope.

If you just want to look at waveforms but are smart enough that you understand you'll never need one outside of novelty, just get one of the $45 handheld ones.

>>1825724
Why would you need a scope for a DC circuit?

>>1825733
>Why would you need a scope for a DC circuit?
I'm trying to measure the frequency pulse of a coil.

>>1825746
With what sort of input? What is the exact thing you are trying to measure?

Also, why do you think a waveform of any significance will be formed by an inductive coil?

Additionally, what is the extremely precise situation that you would need to measure noise that is already accommodated for in pretty much every IC imaginable?

>>1825751
>With what sort of input? What is the exact thing you are trying to measure?

Tesla coil voltages.

>>1825818
>Tesla coil voltages.
It seems 400v is around max, this might not work.

>>1825733
>Why would you need a scope for a DC circuit?
A wild moron appears.

>>1825818
You would be better putting the money towards a good multimeter like a Fluke that won't explode and/or maim you while doing high energy measurements.

>>1824556
>class iv voltages

I'm doing class 1 and 2. That's what makes this dangerous for the gear and myself.

I need about 150,000 volts maybe 100,000 volts work. I'm certain 150,000 volts is the range I need to play with. It's almost no current. almost can kill you. I know.

I like how you googled something that had nothing to do with meters, such as the swiss grid (and I know you're a fucking burger so this is even more hilarious) classification of infrastructure voltages instead of the International Electrotechnical Commission, whom categorize meters and the capability of handling voltage. Pity it doesn't reach that, none of those do. The very notion that you can buy a 150kv touch meter, for 300 bux is laughable at best, much like your understanding of how north American electrical standards work. I also tire of your innate desire to drag this thread on with your retarded goalpost moving bullshit as this thread lavishes you with (You)s.

What you want is a 150kv probe/divider such as the dvr-150 on hvinc dot com. You could of googled or watched YouTube for this or at least shared your use ideas but instead, once again you provided so little information to maintain some kind of conversation it took 100 posts and (You)s to get to the fucking point. Much like every other thread you start.

If you ever reached 150kv on your bench once you'd know looking at 300 dollar scopes on alibaba was hopeless and highpot shit takes a quote every time online. I doubt you've ever seen voltages over USB in your life.

Wayne Lambright, you are full of shit.

>>1826128
>I like how you googled>>1826128
>Wayne Lambright, you are full of shit.
Actually we humans are 98% water. You're wrong.

I might not have used the right electrical jargon, forgive me for trying to do something. If we were in person and you acted this way, how weird would that be for you? Very weird. Grow up.

>>1826128
>drag this thread on with your retarded goalpost

Shut the tread down, like I give a fuck. I got what I wanted, rogal is some OK stuff.

>>1826316
>If we were in person and you acted this way, how weird would that be for you? Very weird. Grow up.
Wayne, take your own fucking advice here, you act like a fucking wack job

>>1825871
Okay oh wise one, besides digital io readings, which op had not said anything about as a requirement, why would you need a scope for DC? Especially something like a simple led circuit.

What could he do with a scope that he couldn't do faster and easier with a good multimeter?

>>1825818
Why TF would you need a scope for a Tesla coil? Were you hoping to make a Tesla coil speaker like all those cool YouTubers that you are trying to copy?

Did they have a cool scope in their workshop and now you think you need one too?

Did they press a button and make cool colorful lines appear?

I'm sure that'll make you feel super special if you do that.

Have you ever asked yourself why you are trying to copy others? Or why you think that if you do exactly what they do somehow you'll also be original and creative just like them?

If you don't know what you need a tool for, you don't need the tool

>>1826345
>Why TF would you need a scope for a Tesla coil?

The secret to unlocking gravity is a tesla coil. I need to know some stuff I can't find.

The reason we don't have gravity control is that it requires high voltage and the early invented were killed off. Tomas Tosend Brown figured it out.

>>1826345
>If you don't know what you need a tool for, you don't need the tool

I know I can beat you over the head wiht the tool and kill you. Fuck off cunt. I know what I need.

---

Not this scope.

>>1826351
Okay, let's just pretend we didn't hear any of what you just said

Why do you think you'll be able to measure high voltage with a scope?

Why do you think anything dealing with a matter carried force would impact gravity?

If electromagnetism could impact gravity, why do black holes still have a gravitational pull?

Or better yet, how would you explain dark matter? Something that does not interact with EM, but does interact with gravity?


Please seek help

>>1824310
EE here,
the siglent models are nicer than rigol but for the price ds1054z unlocked to 100mhz is an excellent deal.

>>1826535
Yeah but op wants one that can unlock gravity, which one does that?

>>1826535
was looking at the siglent 200mhz 4 channel but went with the 1054z because it costs less, hopefully don't end up regretting that

>>1826474
>Why do you think you'll be able to measure high voltage with a scope?

I don't anymore. it has limitations. I still need it for my power supply that I need to build to pulse my coils. I have other projects I'll need it for. I'm th inking of building a dash for my KTM dirtbike, oil pressure, water temp, rpm, throttle position, front wheel speed, rear wheel speed and GPS to map my data.>>1826474
>gravity
Gravity isn't what you think it is. So I can build a thing to push it back.

>>1826474
>If electromagnetism could impact gravity, why do black holes still have a gravitational pull?
I actually think blackholes are one of many negative poles in a galatical dipole system of manetics, think of it as a drain. The magnetic force is so strong, it does what it does and it doesn't exit, it is not ejected either, it is teleported to the positive end of it's own system. It's my own theory.

>>1826559
>Yeah but op wants one that can unlock gravity, which one does that?
Mother fucker, that was funny.

>>1826535
>price ds1054z unlocked

with my luck I would fry it, void the warranty and pay what I should have had to get a better unit in the first place. I'll just start low end, cry and build up as I need, mostly crying, I love to cry, crying is the lubrication of my life.

>>1826587
nice KTM I used to have a 525EXC, 2004 street legal etc.
that bike was epic, I miss it a lot.

>>1826589
>525EXC, 2004 street legal etc
WOW, that's an awesome bike. I was looking at the new ones today.

>>1826589
>KTM I used to have a 525EXC, 2004 street legal etc.
>that bike was epic, I miss it a lot.

Why did you sell it?

>>1826598
I traded it for a 1971 toyota hilux, I really wanted the truck and they offered to do a trade.
It's a nice bike, the RFS motors were bulletproof and long lasting for how high strung they were, a very good and well balanced bike/motor.

>>1826535
>ds1054z
Looks good. I'm sure I can unlock gravity with this. Thanks guys!

>>1826601
>1971 toyota hilux
Those command big dollars these days, like 40K.

>>1825724
>It's a waste of time
Can confirm. Made one based off stm32f4 and it won't make more than 1.75Ms @ 6 bit noisy ass signal. It a complete bitch and three quarters to get working, was a fun project though, masochistic kind of fun.

>>1824675
I love Dave but he's so obviously full of shit when it comes to the deals he gets.

He's in a big upscale office building with other labs and shit. Companies throw out decent hardware all the time.

this little fucker

I don't know how to use one or why I'd want one. Recommend me a good one under $200.

>>1830846
Just get a harbor freight multimeter, stopwatch, and some graph paper. There you go. I saved you over $190. Same fucking shit.

No

At what price point it makes more sense to get a new cheapo chink DSO rather than an old used analog scope? I keep finding only ancient CTO for almost the same price of any DSO on banggood shipped from EU, which doesn't make any sense to me.

>>1831666

For lots of the things I do, having storage capability trumps everything else.

>>1830864
Okay, I did this, but now all of my wave forms look like Thanksgiving hand turkeys

>>1831666
It's not about the price it's about the application. Handheld scopes are ALWAYS shit though.
