Here are four (actually seven!) easy ways to blow up or damage your oscilloscope, signal analyzer, spectrum analyzer, vector network analyzer, DMM, power supply, function generator, or pretty much ANY piece of test equipment you may come across. It's surprisingly easy, and you can damage your gear without ever feeling it!
Electrostatic Discharge (ESD) protection measures are no laughing matter when it comes to dealing with sensitive test equipment.

Today we’re going to look at 4 easy ways you can blow up your test gear with ESD or the wrong inputs. It happens to people all the time. Electronic damage to test gear is caused by an excessive amount of power going into an equipment’s inputs, and that power gets there a few different ways. If you want to blow up your test gear, follow these tips.
#1: Apply overvoltage to the equipment inputs
The easiest way to blow up your test gear is to hook up any signal without knowing it’s characteristics. Sure, test gear’s data sheets list the maximum input parameters. And sure, equipment has built-in protection mechanisms and will often warn you if you are outside the spec.
To avoid blowing up your equipment this way, don’t exceed the maximum input power or voltage on your gear. Also, when connecting to an unknown signal, start at the lowest sensitivity and work your way down to the signal. Essentially, you always want to keep your signal completely on screen.
#2: Float yourself -
As you can see with the ESD meter, an ungrounded person (or a person with a wireless ESD band) can have charge. The charge can then be transferred right into the equipment, or to an ungrounded conductor. Then, when this board is connected to equipment it can damage the gear.
To avoid damage, make sure your mat is properly grounded and use corded ground straps.
Note that wireless ESD bracelets (also known as wireless ESD straps and wireless ESD wristbands) DO NOT WORK!
#3: Charged Boards -
If you aren’t careful, your boards can charge up via induction, and then zap your gear.
To avoid this damage, keep charged materials at least a foot away from your boards and use appropriate materials. If you’re transporting boards, you should also completely seal them up in static shielding bags so they don’t charge up during transport.
#4 Charged Cables -
Believe it or not, the center conductors of your cables themselves can build up a charge through induction. So, to blow up your test gear, just grab a cable at random and connect it up to your gear without discharging it first.
If you want to avoid this damage, you should discharge your cables before using them.
#5: Use ESD Mat Standoffs
Sometimes you need to be extra cautious, especially when working with exposed assemblies. A good ESD mat has a resistance in the 10E8 ballpark, which is often pretty good insulation. But if this isn’t enough, use standoffs to keep your board off the mat. This lets an air gap be your insulator and ensures that your exposed board assemblies don’t have any unexpected paths to ground.
#6: Never Trust Pink Packing
“Pink” packaging material pretends to be static-safe, but often, it’s not. To be safe, simply don’t use it for your boards and instead use ESD-approved mats, standoffs, and packaging.
#7: Cap your equipment inputs
If you aren’t using a channel, cap it. This helps avoid incidental contact that could lead to ESD trauma.

The best protection is being too poor to buy a scope
I'm safe then :'v
One day it will come! =)
Well s$&t
No scope no damage
360 noscoping like a pro
The whole "Make a static video" thing was an awesome dad joke. You win the internet today.
I’m coming from the boom guy (electroBOOM) +]
Me too!
You can really see that this video was influenced by him
Me also
Me three
me tooo!!
You guys legit used a Minecraft Note Block music... I loved this video..
Daniel - it's always nice when you can have a bit of fun and laughter when you're learning something...and it's nice to see a large T&E company can do the same! Keep the new video series coming. Merry Xmas to all at HP, oops, Agilent, oops Keysight! ;-)
Thanks, Dino! Merry Christmas to you & yours
3:16 is that noteblock music I hear?
Yes
@@imsmart. Minecraft lol
Kudos Keysieght. I cant belive i subscribed to a corporate channel.Your vedios are well explained and fun.I think editors and precenters really loving the job.
Thanks! We definitely enjoy it :)
Presenters
I can't WAIT to pick up a wireless ESD bracelet for my wife! Remember strap it and cap it to stay safe!
Educational and entertaining at the same time? Shocking!
sees the title, looks at my keysight oscilloscope, not today buddy not today.
Definitely some good things to keep in mind in this video. I'm surprised that anyone who gets in to electronics would think those wireless wrist straps would do anything at all to protect against static buildup. The pink foam stuff and the pink bags used to ship some components are static disipative. Dave Jones showed how parts inside a pink plastic bag can still be zapped by static electricity. You are better off using the black conductive foam and those shiny silvery type of bags. The silvery bags are anti-static and will protect the parts inside.
Okay I have no idea why havent I subbed to this channel in the first video I see I heard the funniest joke on the whole day. "It would be just a static image... and then the conversation went downhill" Hahaha. Amazing work! Great balance of education and humor! I'll definitely buy a keysight scope as my first one!
That bushy eyebrow guy sent me here good channel keep it up
Great video! Right on point with ESD. There's so many safe guards in place but never heard or thought of cables picking up a charge.
That was one of the most fun electronic video I've come across
Just started my electrical engineering course on monday, good to know before a wreck something! lol Thanks! Always great tips from keysight!!
Good luck with the maths.
Great video! I love the humor and sound effects!!! Keep up the great work sir.
Great video, didn't know the pink foam could become charged.
This needs to be advertised widely
Amazing video!
Very funny and informative
That title just SCREAMS ElectroBOOM! Thank him for bringing me to this channel! (Awesome videos by the way. I even subscribed to Him and this channel!)
Thank you
Daniel staking his claim to Photonicinduction's throne.
So..a good tip would be not install 1960s shag carpet on the floor of your home lab...

Also, NO EQUIPMENT WAS HARMED IN THE MAKING OF THIS VIDEO!
If it's good enough for Electroboom then it's more than adequate for me.
2:24 wait, what!? "I don't want to die and more importantly, actually I don't want to blow up any equipment" Daniel seems like you have your safety proity in order.
The Nightmare Before Christmas
becomes. ESD before Christmas. hahaha!!
Merry christmass
Nice video thanks for posting
Merry Christmas!
5th way wait to new years eve and put as many fireworks on it as you can find.
seriously these tips can be gold. i havent blown any piece of gear yet and took none of these precautious ever. but it can happen easily the more sensitive the equipement the easier. though you guys should know that input protection is crucial hence having build in some for sure.
Love the videos, funny and insightful. No more corporate robotic B.S.
Thanks!
Guess I'm just lucky that I can't, and won't for the foreseeable future, be able to afford anything in the keysight line up.
Crt Tek's goin strong, even if they're not fast enough.
Not ESD related, but what always bothers me is students connecting signals with a DC bias on into an RF spectrum analyzer. The pink poly stuff is evil, prohibited from a lot of cleanrooms because of silicones. Metalized film bags and a ESD ionizer
we have a DC blocker permanently connected to all spectrum analyzers that come in contact with students :D
Love it
Notably, probing a 12V 1200W earth-grounded supply backwards by accident will light your scope lead on fire, but actually your scope will be fine. As long as you put out the fire, anyway.
That static video bit, good stuff! I love those types of corny dry jokes
ElectroBOOM sent me, hope my subscription gets you closer to your subscriber goals 😎
Dragging long cables over carpet! whoooo!
What fun ! Lol I love this dudes last name
Had a strong static discharge on the desktop computer case, it was grounded.
It reboted from it, just like lightning, induction did it
Bonus points for Christmas Eve !
Merry Christmas!
Here from ElectroBOOM .Gimme da keysight.
couple years back, I was fresh from school and basically had no idea about ESD effects.
At the time our company was located in a nice building "loft/open space" style with a glass square in the center of the floor, and we all had our desks around it, on the wooden floor.
I had a 2k€+ prototype on my desk I received the week before, and was trying to debug a component failing during bring-up. The CEO comes check on me and the bringup. At some point during my explanation he goes "is that this component burning down?" and points directly at the CPU. We head a loud "TAK" and the board turned off for good, never to power on again. I wasn't sure about the issue I was initially chasing down, but there was absolutely no doubt about this one!
Since then we put ESD-safe flooring everywhere there can be electronic components.
Ouch!
MAD! ⚡️F220E0 blowin’ up !!⚡️*
TQ it's gonna be very use full
My lab setup is looks like junk yard
I am think that how they will damage .but finally understand it ...
Glad it's helpful! I learned a lot while putting this together, too
I came from electroboom uh... twice now? ;)
It was a good thing keysight split from agilent.
Can i get some of those *scracthing my neck* keysight scopes.
I need one of those scopes! (I am an ElectroBOOM viewer)
Mr. Demille, I'm ready for my closeup 🎥
Excellent INFOtainment. I actually missed the in-laws opening their presents 🎅 but it was worth it 🤓 Thank You!!
p.s.
ONE DOES NOT SIMPLY insert subliminal cuts.... and get away with it 😁 Busted!😎
Wow! I had no idea pink foam was that useless! I always just sort of trusted it because it was supposedly made for that application. Very good info here!
Not sure if I missed it, but was it also mentioned here that ESD damage can be cumulative? Just because a poor practice doesn't wreck something the first, second, or third time, doesn't mean that damage isn't adding up.
Yes, static discharge can weaken or damage semiconductor junctions without actually causing immediate failures in many cases. Spike damage can manifest itself as failures later on for no obvious cause or reason. For example I've experienced controller board failures a week or more after a known mains voltage spike incident (took out the cheapo surge protector and caused the RCD to trip). A week or two later I had a controller board (not protected by the surge arrester) fail and the only reason I could put it down to was the big spike a week or two earlier. This is why the problem is so insidious: people think they get away with ignoring ESD issues because they don't have immediate or obvious failures, and the failures they *do* have are put down to "unknown causes".
What effect does USB have when connecting to prototype boards?
Thanks for using what appears to be a $1M piece of gear to demo ESD damage.
The stakes are high!
Very nice, but you forgot to say, that it is a good idea to connect a 1M or higher value resistor between you and ground.
Becaus if you touch the "hot" conductor from the mains and are groundet you would get a massive shock and maybe die. The 1M resistor would limit the current in that case to a safe level and you would only get a small shock.
my home outlets aren't grounded at all, how am I supposed to ground myself ???
I’m here to get you to 100k sub 💥
Hey Daniel, question, is it safe to “discharge” myself to to instrument metal case or the nut of the front panel connector on a VNA when not having the ESD strap?
The case is typically grounded and an ok option. The nut on the connector works too, but you have to be super careful that you don't hit the center conductor on the input.
Electric boom sent me ..
would be nice to win a scope don’t have this brand
definitely going to subscribe 👍
Your comedic timing is on point. It's very hard and I'd imagine you didn't have to study in school.
Oh I had to study a LOT!
@Keysight Labs you should be making more videos man. You're like electroboom only without running voltage through your body and the innuendo lol
Thank you, appreciate it! I have a few things in the works 😃
@Keysight Labs cool. I'm starting a channel I think. Hurricane Fiona wrecked my home and I'm just getting thr work done now. I've slept in my workshop for over 5 months and the wife sleeps on the sofa with the cats. We have no where to fit a bed. The end is in sight though. I had to give my 3d printers and some other gear away. I'm still a noob and I've been soldering a different circuit every day. Haha
I'm building a giant robot arm for thr local non-profit makerspace that can be controlled with a ps5 controller in hopes of getting some kids in to learn. Management doesn't seem to gaf.
@Keysight Labs I have a software engineering degree I never used and went into policing for 2 decades then was forced into retirement. I remembered how much I loved this stuff and basically live it and do charity work. I would do smd practice boards alot so I wouldn't be one of the belly achers lol. I majored in big data algorithms before they took over our lives hahaha
why the max and min voltage in square wave is thick yellow instead of thin yellow
What resistance is recommended for an ESD Mat? I hear 10 something 8, but I can't comprehend what's actually being said.
Anyone else sent here from electroboom? 😂
Me
Me too
I got ESD several discharges, i could feel, into a project i was working on. Everytime it happend I got scared but device didn't got damaged. It was An software defined radio with FPGA and stuff.
Scary stuff!
I have subscribed your channel. I want a 4 channel scope.
I once went to collect a bunch of cheap computer parts that had odd faults (motherboards that would start up but not recognise disks, etc.) from someone and I brought some antistatic bags with me, and the guy looked at me like I was crazy. He said he'd been building computers for years and never needed them as he'd never zapped anything. Apparently it never occurred to him that damage from static electricity doesn't necessarily kill a device outright, it can also cause partial and intermittent failures depending on what gets zapped. Seems he'd been killing computer parts for years and just never realised...
Just bought a DSOX-1204G. Taking it out of the bag it was wrapped in (low density polyethylene) it produced a sizable static charge and it generated a large arc from my thumb directly to the channel 4 input. Physician heal thyself! I appreciate all the the efforts you guys go to to educate users, but I find it a little odd that you lecture us on static precautions then pack your scopes in that sort of plastic.
I would like to buy scope. How to purchase? I'm from malaysian
Let's all appreciate the work and benefits that CART gives us
That cart is my homie
I don't.know if they still sell them but Johnson & Johnson used to sell antistatic mats for your bench to drain you as you stand on it ?...
I'm not sure of brands, but I do know there are flooring options that help.
So if you are that concerned about static buildup, MOVE TO HOUSTON TX. The air here is so humid we drink it!
I lived in College Station and only had a bike to get around, I know it first hand!
Their is also anti-static wear.
I feel so mean to my test gear right now
So they sudgest grounding yourself, but what can I do if my house is not grounded? (Build a long time ago)
It's a longshot, but you could add your own ground. But, as long as you have the same reference ground as the scope you should be ok
It's been a long time since I've snuggled with my cart 😂😂😂
You mean that's not normal?

What scope is that on the table? The big chonky one
That's a UXR - we weren't messing around!
did they use minecraft note block studio in the 3:17?
Electroboom vibes lol
Edit: it corrected to electro book xD
What is the model of the ESD device you using in this episode ?My experience with ESD is bad , I was attempt to fix an EPSON printer & touch the main board with my bare hand & that kill the chip I touched making the printer totally useless .
I'd have to double check, we borrowed it from the manufacturing group here in Colorado Springs.
Would be very useful to get a similar device , thanks in advance
@@KeysightLabs I'd also love to know.
Hello Key sight
Hi!
Once upon a time i killed a multimeter measuring a high voltage output by accident (6000v 100 watt) and magic smoke appeared proper EEVBlog style.
Also, never hold a spud gun with a 100KV spark ignitor between your legs to look if the spark gap innside is too big, because it really REALLY hurts in the sack 😅🤣
My poor mans way of dissapating eventual charges and check for high voltage is little finger on ground and showing the board my middle one :)
"if you are not using it keep it capped", so... why your oscilloscopes don't come with caps for unused bnc connectors?
We're actually in the process of changing that for much of our gear, great question!
@@KeysightLabs hope not in the proces of making your gear more static sensitive :P
Well.... This seems like a reverse advertisement.... But its ...good.
Well... I'm glad you.... liked...it
He can start singing Country Road at anytime
ngl that was hilarious xD
Nice music choice 😂
3:52 *_Anniversary Gift_*
Right!?
You have all the static charges required to blow you up and land in Hollywood ! BUT man that oscilloscope is literally killing me. I need one to put my statically charged probes in to it.
I hope it's not literally killing you! 😅
He's like a meme--y corporate version of Tech Connections.
Haha, I guess I'll take it?
What’s about measuring something and your connection with the ground clamp isn’t really ground or connect diffrent channels to diffrent Potentials with the ground clamp. I think that’s the way that most beginners blow up their osci. Or is your test gear save against this? The clamp isn‘t ground and the clamps of different channels aren’t connected to each other?
This is pretty common as well, the ground is ground, but usually people blow up their boards this way, more than they do their equipment.
your cofiee is still there
I believe that appliances for domestic, industrial or lab use that do not resist static electricity should not be allowed in the consumer market without being marked as electrostatically sensitive equipment or apliance! This should be marked on the device not in the user manual :). if the inside boards of a machine are sensitive to static electricity they should put markings with static sensitive boards inside! near the screw holes :P
2 thing, not really ESD how I have killed test kit, BNCs have 2 sizes that look the same 75 and 50ohms can not remember which has a larger centre pin, so you then need new BNCs sockets, on your kit, so when you have both around have them all clearly marked. then another one is odd, flowing kit i.e. isolated PSU so gound as not the same. this one I saw most on RS232 and screen was no grounded right and we had around 200v between the 2 units (1 was logging the output of the other) everything looks OK but after a few hours you get a fire. (this after about 20 or 30 fire over about a year, we found the problem)
That's a lot of fires...
What's the cheapest oscilloscope to buy?
We recommend the Keysight 1000 X-Series Oscilloscopes, they are our most budget-friendly option
@@KeysightLabs how much money is it ?
Omg. I thought the pink packaging foam is anti-static material.
You put metal standoffs on the pcb? Looks quite unuseful XD
The standoff points aren't connected to anything, it's the bottom of the PCB at other points where there is actually correction that cause problems.
I am glad I got gift receipts for all the wireless static dissipation wrist straps I gave away as Christmas gifts. How embarrassing. :-)
I actually felt bad supporting them by getting some, but it had to be done.
@@KeysightLabs Your community service message was worth it.
have a great holiday season! I will be here loving life with my MSOX6004 scope that has been well protected from static disasters!
2 questions, 1) if i have left the room, then return later with a significant static charge. Then how many seconds of time after putting back on my ESD wrist strap will it then be safe and be fully discharged!!?? This is a very common scenario. But was not covered in the video.
2) If recently washed my hand will that also help to discharge me?? Assuming that the tap is metal and it has a real ground point. Sometime it is hard to be sure about that fact. However in other facilities a green and yellow earth wire is very clearly visibly attached to the nearby pipework which can be traced back to the sink. I am of course thinking about mobile or off site scenarios where you might not have the ability or luxuries to control the situation when compared to the lab / workshop.
This is important to me!! Thank you keysight people!!!
Oh.... BTW how many Mohms resistance to ground for 1) the strap and does that make a significant different to the discharge time?? Because i like to plug my strap into a spare stud connection on my mat, this then means an additional path to travel with extra resistance incurred of the mat. Perhaps with one of the 2 sides being more conductive than the other one. Also that might not be proper use however the cables they give you with these esd straps are far too short to actually reach all the way back underneath my desk to the wall sockets. To the mat is the only place it can reach to be attached. Dear me i feel that getting clear and correct advice for this subject is more complicated than it really aught to be.
It seems to discharge almost instantly, and for practical purposes you don't have to wait once being grounded, you discharge very quickly. For #2, probably yes? But you'd potentially build up charge again right away as you walk back or move again. I'd definitely want to use a grounded wrist strap.
As long as you have a good path to ground (even through your mat) you should be fine, but you can always check it with one of those ESD testers.
That equipment costs more than my life
Mine too, if I'm being honest 😅
It just hurt me every time i saw arcing on those bnc conectors
You'll be happy to know it was just a shell, not an actual scope
@@KeysightLabs oh good then
electroBOOM sent me ... nice to meet you ... interesting here
I wonder how they abused that poor scope to achieve the arcs effect…. Question tho, does it still work? Seems like the arc was jumping from the grounded ring of the probe to the outer shell of the BNC connector? Doesn’t look like any arc jumped to the signal input
Good question! It was a scrap scope, no hope of repair. I hooked up a neon sign transformer to the BNC connection in the back and the probe.
@@KeysightLabs Last time I accidentally discharged to my analog scope (sorry I’m too poor to get a key sight one) and it was fine, I suppose I got lucky and discharged to the outer ring of the connector and luckily it was grounded, it was painful for me tho
Yikes! I've seen folks often touch the outer ring of the BNC to make sure they are discharged. The center conductor is the one to be careful with
