New Uni-T UPO3254E Oscilloscope

[nctnico]

VGA is basically obsolete, although Siglent is using it as well, so there must be some demand behind it. Maybe for classrooms.

I bought a new monitor a couple of weeks ago and it still has a VGA connector. I don't think VGA is a bad choice here. You don't need high resolution and a VGA port doesn't take a HDMI, DVI or display port connector away. You can use the monitor itself to switch between the inputs.

Pending software, UI design and real world testing, these Uni-T units look reasonably good for a cursory glance on paper.
I'm sure I missed a bunch of comparison points, but I just spent 30 minutes doing a really basic comparison.
(Darker green = better, per row)

Hopefully Dave will have a review video up soon, and hopefully unlocking the 150MHz version to 250MHz won't be too hard, along with the decode options too.

I was looking at buying a Siglent soon to replace my Tek TDS210, but this Uni-T has me intrigued....

[nctnico]

You comparison is missing the GW Instek GDS-1054B and GDS-2074E. Both can be 'hacked' to get more features and bandwidth. The GDS-2074E can be hacked to have 300MHz on two channels.

I see that the Uni-T doesn't seem to have peak-detect. I'd avoid buying a general purpose scope which doesn't have peak detect.

Is this thing really better than the Rigol 5000?

It's at least twice the price of a hacked Siglent 1104X-E

[Fungus]

Is this thing really better than the Rigol 5000?

In the "unhacked" state? Yes.   

If you hack the Rigol? Not so much.

It's at least twice the price of a hacked Siglent 1104X-E

Comparing hacked to unhacked is pointless. Retail prices aren't set that way.

[nctnico]

Is this thing really better than the Rigol 5000?

If the firmware works then probably yes but I don't hold my breath. To me Uni-t seems new to serious digital oscilloscopes so seeing is believing.

Maybe Dave's review will clear that up.

(crosses fingers that it deserves a roasting... that way Dave can't be accused of being anybody's paid-for shill)

It actually isn't:
https://en.wikipedia.org/wiki/USB_hardware#Durability

I'm sure we all have a loose USB-B connector somewhere, eg. on an Arduino.

I don't care about rated insertion cycle durability because I'm only going to plug the thing in a handful of times. I care about it getting yanked on and not breaking off the board..
If you are really plugging/unplugging your arduino that many times then USB-C is going to be a better option there.

Is this thing really better than the Rigol 5000?

No not even close. 8Gs vs 2.5, no touchscreen, etc.

I don't know if I'll review it, I did not request this and they did not inform me it was coming, it just turned up (to my old address actually, luckily my DHL guys knows me and that I moved)

Why would you compare it to a Rigol 5000? They aren't the same class instrument.

I'll add the GW scopes and update the file. I didn't go into hacking etc as that is a whole other can of worms and complication.

You could send it to me to review!

$1070 for 150MHz/2CH to $1587 for $250MHz 4CH.
How is this the least bit competitive against say the Siglent SDS1000X/E Series

You could open the box and take a look, maybe.

If it's bad it deserves a good roasting.

Whatever happens you could give it away as a prize.

(Maybe give it away unopened...  )

Exacly. For the price of the cheapest model you can have a Rigol DS5000 or a Siglent+change.

This is what I was trying to say above, I guess I just didn't do it very well.  A bit out of my league here.  I see it has substantially more memory depth,  waveforms per sec and sample rate (on paper) than the 1104X-E, just not sure how they translate into $$. It still falls well short of the Rigol 5000 starting at $1000. So I was wondering what all the chatter was about, other than it was new, and assumed I was missing something.

Almost fell off the chair 

Perhaps DJ is concerned lurking marketing desperadoes will start dumping gear at his door to review and take their chances 

On the other hand, Uni-T may have a price point winner or rebadged Owon/Rigol/Siglent and who else better to review it, than the EEVblog bloke on Youtube? 

Maybe DJ could handball 'surprise packages' like this for review to local EEV-ites and or tubers,
do the best they can and get to keep the product for their effort. 



Anyway, if it ends up on the nature strip I'm certain someone will score a bargain at the local Trash n Treasure 

"How about $20 for it mate, that's all they're worth"

"OK, done deal, what is it anyway?" 

"Crappy microwave, I'll probably have to fix it, do you know if it works?..will you take $15?"

I heard from Uni-T

I have attached a flyer of this scope here, and also want to clarify that we are comparing this product with the following:
1.       Siglent’s SDS2204X: 200MHz, 4CH

2.       Rigol’s DS4024E: 200MHz, 4CH
https://www.aliexpress.com/item/32971171414.html?spm=2114.search0104.3.8.552d1151GF8doO&ws_ab_test=searchweb0_0,searchweb201602_1_10065_10068_319_10059_10884_317_10887_10696_321_322_10084_453_10083_454_10103_10618_10307_10821_537_10302_536,searchweb201603_52,ppcSwitch_0&algo_expid=2d9ee615-60d1-4124-b9a0-fefd802dafe3-1&algo_pvid=2d9ee615-60d1-4124-b9a0-fefd802dafe3

Our retail price of around $1500 is cheaper than the competitor models offering similar bandwidth, sampling rate, and memory (Our model’s specs are a little bit higher than our competitors actually). Also, we have upgraded our software from the old UPO2000CS from awhile back.

The Siglent SDS1000X-E series compares with our UPO2000CS series, both offering 1GSa/s sampling, which retails at around $500USD.

Uni-T throwing the gauntlet for a three way cage match ?     the winner scoring a good slice of the the '2k budget' dollars..   

If it's on, consider to also compare them to a top shelf freshly calibrated 4 channel DSO with same bandwidth
and perhaps one with a much higher bandwidth too, to see how well the three cheapies fare

Features aside, I'd like to see what real BW grunt they have at different levels and waveforms = a six episode EEVblog saga 

Get those contenders working hard if they want the prestige.. and market share

USB type B is still standard on all Rigol gear, a lot of scopes, and a lot of printers. It is the most robust USB connector available.

It actually isn't:

https://en.wikipedia.org/wiki/USB_hardware#Durability

I'm sure we all have a loose USB-B connector somewhere, eg. on an Arduino.

What works on paper does not work in practice. You'd be insane to use one connector over the other based purely on insertion cycles. The newer ones may be rated for more insertions, but a single gentle tug from a distance, and those connectors are gone.

"we are comparing this product with the following..." 

This must be some kind of bad joke or intentional mistake. Using AliExpress like "reference" tells lot about this kind of marketing... how I can say it nicely - completely lower class, unworthy and unprofessional from whoever here in Dave's message was quoted. Maybe the world have changed, under the leadership of the one, and has become such that facts no longer matter.

If look this link, in picture there is SDS1204X but then there in this AliExpress sales ad there is all specifications from very old obsolete Siglent SDS2000  (without X) and  (1 generation FW) series.
Even it have today (2x) 70M memory after 2nd generation FW's, not 28M. 
SDS2000X series have  (2x) 140M.

In China Alibaba/Expres is THE place to buy stuff, so natural they would use that. Probably just did a quick search for the email. No big deal.

Unit-T should dip into the Xmas party stash and hit on aliexpress for those two scopes,

and send to DJ's correct address 


i.e. Come on Uni-T, if the new scope is half as good as the claims, what's another 4k to blow in the high flying corp world?

Any members nearby want to lend Dave their scopes for a day?
