And this, gentlemen, is why you should never leave your tech demo unattended while a crazy aussie bloke is lurking about with a screwdriver...

@EEVblog 11 лет назад

Yes you did, just like many people do. I am NOT against USB scopes, I used to design them myself. But they are NOT a tool to replace a bench scope, they have more niche uses.

Love the foot pedal microscope. Very clear pictures and ease of use for rework.

@EEVblog 11 лет назад

No worries. Thanks for being in the "live studio audience"!

@Sinusoidal 11 лет назад

Was great to watch Dave do his stuff live. Thanks for taking the time to chat to us at the show, really appreciated.

@Knight8365 11 лет назад

Just having a little squint at these Picoscope machines, and they have drivers available for Linux for some models such as the 5000 series. It ranges from GBP800 to GBP1700. Thanks for the great teardown Dave - it was lots of fun on the fly like that.

@stationplaza4631 11 лет назад

I just love how Dave does this stuff. Just firing off about the origin of the internal parts immediately like that!! :--) He's definitely top of the heap.

@tonybell1597 11 лет назад

Excellent "Drive-by" tear down Dave. That microscope is superb for the likes of us "hard of seeing" types.... Must look at something similar for my own workshop.... Looks like a great show.. Cheers.

@EEVblog 11 лет назад

They are not the same market as a regular bench scope. You don't buy a USB scope to simply replace a bench scope. You chose it for extra channels, higher resolution, infinite memory etc

@EEVblog 11 лет назад

It's in the description

@EEVblog 11 лет назад

Just the combination of the lens(s), the sensor, and the low volume all add up to a high price for a purpose designed instrument.

@EEVblog 11 лет назад

When you buy a company, you take on responsibility for all existing contracts. I doubt Picoscope were big enough to warrant a supply agreement, but I could be wrong.

@FredrikRambris 11 лет назад

This is cool. Not many people can tear down a demo product, run accross the hall with it and hog another booth's equipment. You da man!

@robertmccully2792 9 лет назад

Its the software that makes pico and sets it apart from the Rigo... a large screen is nice also. And all the tech support from pico and users.

@happyhippr 4 года назад

Gotta second that, the ability to save your waveforms directly to your PC to re-open later is a game changer. great for engineering reviews of developmental testing results

@MattHollands 8 лет назад

Watching you use the wrong screwdriver for the screws made me wince. I've damaged far too many screws like that.

@Billblom 4 года назад

That microscope was VERY neat.... Love the zoom!

@gamccoy 11 лет назад

Dave you were like a kid in a candy store: Gear to tear down, cool microscope to demo, plenty O' fans to admire you. A good day if there ever was one.

@EEVblog 11 лет назад

I did not take any of my wireless mics, so just using a shotgun, and also auto-gain. When shooting impromptu video at such an event the last thing you want to do is dick around setting up for good audio.

@Afrotechmods 11 лет назад

Very cool microscope!

@brodyuriel1142 3 года назад

I guess Im kind of off topic but do anyone know a good site to watch newly released tv shows online ?

@TilmanBaumann 11 лет назад

Man I hope Tagarno is as excited as I am about the better video quality of your teardowns. (Despite the wonky camera work and filming off the screen) Hope they send you a 'demo unit'. :)

@krawutzimon 11 лет назад

Yeah, that one had me instantly drooling ;) Those foot pedals must be making work so much easier.

@AlexForencich 11 лет назад

You should be able to get 16 bits across all four channels, just with a lower bandwidth. Averaging four times gives you one additional bit of precision. Looks like the chip can do 12 bits at 160 Msps and 80 MHz bandwidth on all four channels. 13 bits would require averaging 4 times to 40 Msps and 20 MHz. 14 bits would be 10 Msps and 5 MHz, etc. The chip can do time interleaving to get higher sample rates with fewer channels; you can get 1 Gsps / 500 MHz at 8 bits resolution on 1 channel.

@dumbo800 11 лет назад

Exactly. Unless you are close miked (a lav or over-ear) you will always have this level of background noise. This is excellent audio quality for this sort of venue and situation. You have a professional microphone in the right pick-up pattern (shotgun) for camera-mounted work, giving you a full spectrum and quite lovely sound for a remote record. I hate crowd sounds, but only when they are very poorly recorded. This recording makes it sound like the viewer is there. Kudos.

@RTFMn00b 7 лет назад

As a complete noob, my guess on the cutouts on the cans, aside from decoration, would be for heat dissipation. Purely a guess, you may have already considered it, and/or I could be way off. Just doesn't seem like something they'd do without some functional reason.

@kempy666999 11 лет назад

Excellent close up shots with that microscope. You should get the Tagarno guys to give you one of their microscopes for teardowns. It would be good advertising/publicity for them.

@nerdydev 11 лет назад

did you just sit down and start using that microscope? :O

@EEVblog 11 лет назад

There is no resistance to PC based scopes, they have their uses.

@vencibushy 9 лет назад

Dave, will you be doing any reviews on some of their models?

@chris746568462 11 лет назад

Bottom right at the start of the video you can see a Rigol Dp832 power supply. I hope it has the revised board in it.

@guillaume8437 2 месяца назад

Thanks EEVBlogger for this nice video. What did you say the op amps were? I can barely read it. And about the 16-bit resolution, we need to reduce the use to only one channel or just reducing the sampling frequency is fine?

@ElectronicNutshell 11 лет назад

I love teardown videos and wow you even did it at the Electronex show, amazing :)

@samuelfranklin9179 7 лет назад

any thought about the Picoscope 3000? would it be a good multipurpose Logic analyzer/scope to buy?

@wadehicks9270 8 лет назад

Always great info

@Cydermaster 11 лет назад

Dive-by Teardown -- love it -- made even better by hijacking that amazing 3d microscope. One of the best vids you've done

@EEVblog 11 лет назад

It was just random. Was standing there chatting with a bunch of EEVblog viewers and I said I should just tear something down for fun. And well, that was the closest item to hand!

@BOMBOVA 11 лет назад

thanks for the video. i am enjoying your investigate, and report stories, more and more. your rather skilled , doing this on the fly, wonderful microscope, i am going to get a low cost one. Thanks Dave, Cheers from Thomas in VAncouver,

@Thermoelectric7 11 лет назад

It was at a big trade show with lots of people, and Dave mentioned the audio may be bad due to the microphone. A bit unavoidable due to where he was filming.

@EEVblog 11 лет назад

Of course that microscope is not ideal for recorded video work. I'd either have to point my camera at an LCD display, or use a PC and capture box and external mic to get live video recording directly from it.

@JosefdeJoanelli 11 лет назад

I cannot believe I missed a live tear-down at the show...

@profcwarner5674 11 лет назад

Pico and others do 60 & 100MHz, 1 Gigasample scopes for far less but this is a high resolution scope (12, 14 & 16 bits). High res scopes cost a lot more. Aside from being high resolution it has way more memory than other scopes at this price (32,000,000 samples). It also has things like segmented memory, serial decoding and mask limit testing etc which are cost options on most scopes. It also has a built in signal generator / AWG. Perhaps it is an insanely good price?

@PaulHenning84 11 лет назад

Hey Dave great video, just thought I'd say I just purchased another peice of hardware you reco'd in your video (the xclite cutters, hakko iron and the exetech $50 DMM). Your videos are great. Saving for that oscilloscope.

@BarriosGroupie 11 лет назад

The whole point of scope-boxes was portability and saving on the cost of a screen, and computing power, which was left to the host computer. But these are cheap nowadays compared to the digitizing front end. You'd have to be stupid nowadays to buy something like this over a portable Rigol scope with a nice screen and onboard computing power.

@dougspurell2387 8 лет назад

Dave, to look under the shield cans use am NDT xray

@Astinsan 9 лет назад

Loved this one...

@MelodicMurder 11 лет назад

It would be perfect for your lab. Great teardown.

@tbbw 11 лет назад

That microscope is a toy i would not mind seen used in the EEVblod... even doh it's been filmed from a screen showing the board the pic is awsome.

@1010tesla 11 лет назад

How much is the microscope? I hear the price during the video.

@RichardsWorld 9 лет назад

That microscope sure was nice.

@ferdinandmravenec1636 11 лет назад

Sometimes 8 bits is enough for oscilloscope. 16 bit for sample seems like overkill for me.

@IvayloIvanov 11 лет назад

I've wrote them a letter already. I suggest all of use to do this. I believe we can pull this out :)

@cybermaus 11 лет назад

Nice impromptu tear down. But what I really would have liked to see is testing it. Is this the end of your resistance to PC based scopes?

@Mystickneon 9 лет назад

I want to see that microscope in the lab. Get on it :)

@paulbendel 11 лет назад

Would Picoscope have had an agreement for a long life on the ASD chip that any purchasers of that company would have to honor until the agreement with Picoscope expired? Or would such an agreement be null and void with the sale/ takeover of ASD?

@phigolden2706 7 месяцев назад

What do you think of the pico scope now 2024?

@nilssab 11 лет назад

would that make a 3d microscope? I'm no pro, but my guess was that it scans a over many focal lengths, combine an image constructed the most focused part from each frame, and then output that to HDMI do get an icreased focal depth and the ability to view the object in 3d..

@EEVblog 11 лет назад

if enough people emailed them perhaps they'd send me one! Still not ideal for efficient recorded video work though, but would be very useful.

@mortensentim511 11 лет назад

If he gets one I imagine the soldering tutorial videos would get redone.

@ian-c.01 11 лет назад

Noooooo, it's 2am here and I need to sleep but just got notified that Dave has uploaded another EEV Blog ! Watch or sleep, watch or sleep, watch or sleep ?

@dobrew9 11 лет назад

do they work for laboratory equipment?

@EEVblog 11 лет назад

That model is about $3500AU

@joelie83 11 лет назад

Dave, you definitely should buy that microscope for your tear-down video. You know you want to! :)

@Tannz0rz 11 лет назад

That microscope is AWESOME

@MrROTD 11 лет назад

I know right? it's the best screw in any situation

@PilotPlater 11 лет назад

only dave could get away with going to a show and taking a product from one booth, tearing it apart, and looking at it in another booth's microscope.

@Ecobion 11 лет назад

Dave, always thought you were dead set against USB oscilloscopes, yet you spoke very highly of this one - I avoided getting a USB scope in the past, did I mis-interpret something?

@ChipGuy 11 лет назад

Haha, really like that sort of "pirate" teardown. Picoscope may have also chosen this small company in order to get a good deal and a supply contract so if Hittite would have scrapped this product they needed to pay a big fee to Picoscope. Who knows. Anyway its always nice to see teardowns for exactly these chips you didn't have a clue about before. Well done.

@DavidLeeMenefee 11 лет назад

What is the bandwidth and price of the unit?

@EEVblog 11 лет назад

I'd happily pay $1K for something like that, but it's not that price here.

@ThePbatemon 11 лет назад

I couldn't help but laugh a little that you just ran to a booth and used one of them :) seemes everyone there was really nice

@prosunmaitra9513 8 лет назад

sir...What is the maximum voltage we can measure with it???

@cwgreenley 8 лет назад

+Prosun Maitra Friendly tip, don't ever start a comment on the internet with "sir." Also this is in no way the appropriate location for such a question. Considering you could just google it yourself, there really isn't any appropriate location for such a question.

@RalphJeffreySteinhagen 7 лет назад

[..] ±10 mV to ±20 V full scale, in 11 ranges [..] according to: www.picotech.com/download/datasheets/picoscope-5000-series-a-b-data-sheet.pdf

@bloodaid 11 лет назад

Dave, what was the brand of that microscope? I think I fell in love

@dmitrygrey 11 лет назад

Fascinating ADC )

@wernertrptube 7 лет назад

Next time I will make a look the same procedure at the electronic Fair.Seeing what the electronic stand People will say ??????.

@MrROTD 11 лет назад

Mr Jones is goddamn epic, it's gotta be said.

@LatinPercussion 11 лет назад

Thanks.

@DIYTAO 11 лет назад

Nice,. Using Danish microscope to view Norwegian AD-converter.. And this happens in Australia.

@happyhippr 4 года назад

gotta love it

@Zauviir 11 лет назад

Get one of those microscopes for teardown!

@cuzOoba 8 лет назад

Where do you think I could get a scope like that for under $50? Is there a way for me to get one for free or possibly make one (that isn't TOTAL rubbish)?

@happycline 11 лет назад

story of the love holes: a big company, cold and heartless, realized people want things with 'love put into it' so after a Google search, looking for this mystical 'love' they saw pictures of hearts, so now with every product they make, they add a little love, by adding heart shaped cutouts ^.^
