The copper squares are there so that the areas with traces have the same amount of copper as "blank" area. This keeps the layer thickness consistent, otherwise the prepreg will flow towards blank areas during board production.. This is important for impedance matched boards, where the layer thickness affects the trace impedance.
Any manufacturer is free to send me stuff. Agilent just happens to send more stuff than most. What am I supposed to do? Say no to checking out a cool toy for everyones benefit lest I be worried that people will think I'm somehow "selling out"?
I do not solicit this stuff, so if you want to see more of other brands, tell the manufacturer to send them to me!
As @ConjUK said, it's a good chance to see inside gear you might never get to touch in real life. I can't afford this stuff either, so I'm not going to say no when a manufacturer offers me one to play with!
That ferrite looks more like a grommet
7:40 Dave I don't think that there are 4 channels supplying 12V 15A each. As you can see at 1:24 the maximum input power of this thing is 180W. This is the power one 12V 15A rail can deliver alone. If there are 4 channels the input power would be 720W max.
8:00 That is a ferrite ring? Looks like a wire pass through rubber case insert to me...
It stands for High Potential, or high voltage. It's basically a test on the insulation of components to find where their breakdown voltage is.
The side handle cover locking mechanism is exactly the same in this, that it was on a HP 3577A I took apart, to fix the GPIB module. It was really nice modular design.
2:12 -- we used GPIB at school few times (measuring characteristics of power generators and such things) :)
One Agilent's EE told me that their quality has improved since the production in Malaysia. True? Who knows, We have discussed the use of ceramic (33220a) instead of tantalum capacitors in their function generators of new generation.
Thanks Dave, great video. I worked in production with agilent equipment. They are magnificent.
I've progressed infinitely since last time you asked!
A bit disappointing it's not made in Germany, but Agilent have invested massive amounts into their Malaysian plant.
Nice teardown. Cant wait for the performance review.
I am pleased to notice that the Agilent 81160A uses the same brand stuff (XILINX) as my Siglent SDG1020 AWG (as seen on eevblog forum's "siglent-sdg1020-waveform-generator-teardown-pics" )
XC95288XL = XILINX
SPARTAN-6 = XILINX
Catch you next time!
Happy Tuesday!
Great bit of kit, Dave! Excellent teardown :)
Oh man. I've used the AD9739 before and that is a BEAST of a chip. Should look up the clocking in the datasheet sometime. :) The main sample clock comes into those, and then drives the FPGA clocks from there. I'd wager that a V6 or a 7 series FPGA is what's under that heatsink.
Nice piece of kit. I'm just learning about all this stuff, what would a function generator be used for?
Copper or silver plating would have better conductivity. Gold is usually used in electronical equipment because it doesn't oxidize.
I've always wondered, I see on a lot of electronic gear a sticker that reads "Hi-Pot OK" or "Hi-Pot" passed. What does that mean, exactly? (@1:25)
Why did they put ferrite ring on the PE-wire? It is probably a bad idea.
At least I can imagine two purposes:
1. Shielding
2. Etching solution economy / etching-stage time decrement at PCB manufacturing stage.
what are those tiny copper squares for, which are all over the pcb. They aren't connected to anything.
CCFL backlight - retro!
Perhaps you missed my $30K Tek scope teardown quite some time ago?
For me, thats the great thing, seeing some awesome gear that I could only dream of. lol
Really nice piece of equipment! I wish I could afford A function gen like that... I can't even afford to stand in the same room as one!
Hey Dave, just a little question that if you buy some tech gear and it is very expensive, so does tearing it down or showing it increases the profit you gain on your website? For example : you buy something which costs $1000, so does the profit increase by $1000 or more?
@8:48 what is that samll square unconnected pads everywhere in the pcb. any idea ?
It's a big step up from the Handifax.
I bet you could whip up an LED-lighted periscope in no time. You can buy plastic "dental mirrors" for about a dollar that would work a treat. Great for peeking under and behind things you don't want to remove.
@eevblog when is the review of it coming
no full teardown? ;(
Did you put it all back together and use it?
And how's your progress with search button? ;-)
Where do you get this stuff??
The blue board is probably the optional pattern generator.
eevblog@ when is the review of it coming
how far are you with your op amp tut ;P ?
Quite the contrast from the Chinese stuff I saw your British counterpart tear down recently :)
My god.. That's awesome! I just really wonder. How do you manage to convince them to send you such expensive stuff to tear down? I mean I know your trustworthy, but.. you must be a master persuader.
i love tear-down Tuesday
While this piece of gear is excellent, I just don't see $20,000 worth of components + engineering in it. Mark-up must be huge.
And then you have the R&D, softwaredevelopment and so on, that cost a lot too ;) Plus they dont make gazillions of these devices as the mobile phone or computer companies does, which also increases the cost of the finished product.
They come to me. Even if they gave it to me to keep, it's still cheaper marketing than what they'd pay for an ad in a trade magazine. They aren't silly ;->
Sure. Get them to send me stuff and I will. BTW, my audience is around 50% engineering professionals, and 25% engineering students.
ROHS solder looks terrible. :(
Don't see your point. The engineering crew build it in Germany and the assembly lanes are in Asia. So whats the problem? Even the good quality stuffs are made in China, it only depends what money your ready to pay for them.
@EEVblog well thats great news =) at least because you, the crazy aussie, answered to one of my comments =)
Dunno maybe because of the frequency or something
The p is silent, as in the bath.
Cheapskates - couldn't be arsed to put a silkscreen on the PCB!
Sadly, no, it's going back.
How come you did not suggest to Agilient not to use cheap "made-in-China" component in this super expensive instrument?
Things tend to get lost in the post these days :)
The exposed copper gets rusty, the gold will never oxidize
Only disappointing thing was the "Made In Malaysia" sticker on the back. Was hoping for $20,000 that this thing would have made in Germany using hand forged steel with the hottest burning coal money could get.
Haha, I also like to take things apart even before I turn them on!
Bricks ft advanced. Great toys!
No, it's a loaner, has to go back :-(
maybe! or they put on gold one cause its cool?
To bad it was not made local . I also think you should rename this video as a partial tear down .
A complete tear down would have been much better.
Damn, does this mean 'pro' egineers are not allowed here? (I don't count myself as pro, but am lucky enough to use equipment like this daily).
Please Dave - Rohde & Schwarz FSVR needs some attention, as does the FSW. I use them every day and would love to see the inside - dam cal stickers and all ;)
you need power screw drivers - may be
Nice Analog Devices DAC, weeeeeeelll above export restrictions to Russia :-D
Great!
As a complete noob, what is it that this can do that is worth 20,000 dollars?
When I say useless is that the gear you're reviewing will be of no use for us because we might never get our hands on one ever.
Done years just to get marginal on this single package block for personal scope usage.
2.4GSPS @ 14bit? Yeesh :o.
I knew my comment would generate hate towards me and I apologise if you guys feel angry or something. I happen to deal with high end gear like the reviewed item and I find this so out of place when you put next to all the other stuff Dave reviewed. I find it a lot less useful than the rest of the gear teardowns. But since Dave is up to review stuff like that now, I happen to know a couple of people in R&S and Tektronix. I will try giving them a call, maybe they will listen.
Electronic parts + pcb = ~300$
They get 40$ per hour of work, i think so ~400$ for 10 hours putting screws in
logistic and cardboard = 300€
putting the Agilent sticker on it = 19.000$
did you forget the engineering design work and R&D? do you think this is outsourced to a Chinese company, that just designs and manufacturers it for them?
When you talk about "useless", please dont mention "most part of people..."
Go say the same thing about every porsche or ferrari article on the internet.
For me, this article is highly interesting, to discover possible differences between my 300euro function gen, and the rest that might exist.
maybe they are subscribers and offer it?
i could buy mine 40 times...
Your getting your money's worth ????, the box is almost frickin empty ;)
The chip at 10:17 has no legs!!!
Its LEGLESS!!!
HElp someone
I am going to sell my wife's car and get one of these. Oh yeah!
what does it matter where it's made in, the design is far more important, any fool can put things together with a recipe
Yeah $20,000 and no LED? Ha
bute!
throw out the stick, it's sex in a box!
Sorry bout commenting that but to the most part of the people of your blog this is useless and it feels to me Agilent has some desire to buy you somehow (I'm not saying it actually happened but it just so feels like it). Please don't do it man.
german ftw =)
