DIY AC Coupling Adapter Hantek 1008C

- One of the problems with the Hantek 1008c and other cheap Chinese scopes is that they don't have AC coupling. This can make it difficult to properly analyze certain waveforms, such as alternator ac ripple ( both voltage and amperage ), relative compression tests, and intake manifold pressure waves, etc... However, it is very simple to make your own DIY ac coupling adapter at home with only a few dollars of parts from a hobby electronics store.

Good job Bob. Nice work around.
Thanks so much for posting this video. My Hantek is driving me crazy and now I understand why.
That's interesting what was the problem you are having an how did the video help you?
@@sailorbob74133 I can not get the Hantek to display any CAN data, nor will it display an alternator ripple. I have returned the scope and will try a replacement later.
very good sir....as soon as i wanna buy huntex 1008C
congratulations for the videoa question what and the box connected to the battery also you can increase the current over 25volt thanks
Thanks for reply and your video
Hi, may be the best upgrade for your solution is to connect simple small ON/OFF switch in parallel to capacitor and mount it on the box outside? This way you''ll get a real AC/DC probe.
GOOD VIDEO
this is best upgrade ive seen yet, I can not see well enough to tell how you connected the ground wire please explain so i can give this a try. thanks
It's been so long since I did this I don't quite remember off the top of my head I'll have to look at it when I get home
I am picking up a Hantek 6022BE USB Oscilloscope and just realized it does not have AC coupling, will connecting AC damage it and either way will I be able to properly see mains AC harmonics with the scope via spectral view/FFT?
You'll need to build an adapter like in my video. Regarding the fft I don't know.
I mean to cut open extra attenuator remove what's there and replace with capacitor and ground wire. What's your thoughts on this
It could work.
i almost jump when you phone vibrates, watching this midnight at relatively high volume from my speaker
Sorry about that at least the video was exciting }:‑)
@@sailorbob74133 no problem, usually i use headset at night, but for some reason i dont lol, but this video helps me, i have Hantek 6022BE that also didnt have AC coupling option
Hi I am using a hantek 1008 and the ht25 to check se notary ignition on a corolla without the coil on plug ignition. Can't seem to generate a stable clear wave form .
That should read secondary ignition wave form
I have extra attenuator ill try and cut open and solder in capactior do you think this will work, thanks again
I'm not sure if that would work. The capacitor already blocks all the DC current so there is no need for an attenuator in this situation.
i have found the capacitor but cant find the bnc connectors were do you get them. thanks
I got them at a local store here in Jerusalem. You could probably get them at an electronics store or off Amazon
Hi, thank you for posting this video. It now makes the 1008 even more attractive.
I'm trying to figure out a way of doing a Relative Compression Test by connecting the scope lead straight to the battery posts, but i want the waveform to be a single crisp line, by filtering out all the noise.
Do you think this method will work, or is there a better way to make a filter?
Many thanks for any help that you may be able to offer me on this subject. Joe
Actually, I would look into the Pico 2204a, which is about $140. It's only two channels, but practically speaking you can't use more than two channels on the hantek most of the time anyways.
Thank you very much for the prompt reply and advice on the pico 2204.
But is there a way that you know of to filter out the noise when connected straight to the battery posts?
Many thanks, Joe
well the sample rate on the hantek scope isn't that high so I don't think you'll see that much noise hooks direct into the battery post I think just try it and see what you get but I think it should probably be okay. Ideally you would want a 1 kilohertz low pass filter which the Piko can do in software I'm not sure how to do something like that for the hantek however, but like I said you may not need it for the ham Tech because the sampling rate isn't that high anyways.

Nice video. Where did you get the little project box? Thanks
At a local electronics supply store here in Jerusalem.
What size capacitor was used?
I didn't say in the video? Been a few years so don't remember off the top of my head...
Hey, sailor! What's the capacitor voltage?
I used a 0.1uF capacitor. I don't remember the voltage rating for the cap, think it was rated up to 25 volts.
What is the number of this capacitor?
0.1 microfarad iirc...
Hello, how are you! My friend, I wonder if someone can help me. I have a Hantek 1008c, and I need to know if I can connect, on a rotation sensor, and on a phase sensor of a vehicle. Here in Brazil I have no one who can help me with this detail. Thank you so much.
Valdir Martins sure why not just back probe the relevant connectors on the signal wire
O Mestre Abel tb tem um livro com mais de 300 imagens de ondas automotivas, que podes baixar totalmente GRÁTIS.
Ahn... I'm from Brazil, and I don't know to speak english. Could You make a list with the materials and a little tutorial of How to make te ac coupling, please ?
Use um capacitor de 100nF/1kV em serie com o sinal que você quer medir, assim a componente DC será filtrada. Comprei um Hantek e me decepcionei por conta de não haver essa possibilidade por software. Mas a gente tem que se virar com o que tem. Abraços, amigo.
i really like your video ,i am more a mechanic than electronics expert like you though, would you post or send me the part no,s to build that attenuator?
It's basically just a 0.1 microfarad capacitor hooked up to male and feel female BNC connectors in a little plastic box.
@@sailorbob74133 ok thanks
Can i buy one from you?
I don't sell them but you should be able to make it yourself with parts from some place like radio shack or something like that believe me it's really pretty easy have faith in yourself.
Best solution I''ve found with Hantek 1008C is to use it as a door stop even in 2021 they cannot get the secondary ignition clamp to lock up the PC etc. so many problems... save yourself the headache and buy Pico.... yes save up but get things that work not CCP China pretend Waste of time Junk! (Oh yes I did try the default device in device manager and the alternative USB driver) all no go... maybe it needs 20:1 attenuator.
