- AC DC Ground Coupling in Oscilloscope, Explained, coupling is a method to connect signal to the oscilloscope input. what is ac coupling, what is dc coupling, what is ground coupling, in Analog oscilloscope, CRO cathode ray oscilloscope, MSO mixed signal oscilloscope, DPO digital phosphor oscilloscope, Digital sampling scope, waveform recorder,
when we select DC coupling, it allows to see all signals from 0 Hz up to the max bandwidth of your scope. while selecting AC coupling, it filters out DC components from the signal. and a high-pass filter on the channel's input signal path blocks all dc level signals and the varying amplitude is transmitted to oscilloscope circuitry
How to select AC DC coupling in oscilloscope
In the channel menu of your oscilloscope, go to “coupling sub-menu” you can switch between DC coupling and AC coupling or Gnd coupling. DC coupling allows you to see all signals having dc offsets, AC coupling filters out DC components from the signal and shows the ac signals only. in Gnd coupling, the oscilloscope's inputs are connected to ground potential.
what is difference between
When you enable AC coupling on an oscilloscope channel, you’re switching in a high-pass filter on the channel’s input signal path. This filters out all the DC components.

In continuation of this video, can u explain, when we need to use DC coupling, when we need to Use AC and ground coupling. It will be much appreciated sir
This is easy to think too much on... It is a simple matter... When you are interested in the AC component of a signal, you use the AC Coupling function. In like manner, when you are interested in the DC component of a signal, you use the DC Coupling function. Very often, when troubleshooting a circuit, you will look at both components, AC and DC. Here is an example of that... You are looking at the output of an audio amplifier, which is AC. The circuit contains a capacitor in series to block any DC from reaching the speaker, because DC will destroy a speaker. So, you use AC Coupling to see that the amplifier is outputting the audio signal correctly. Then, you switch to DC coupling to make sure that the amplifier is not outputting any stray DC voltage. If it is, the amplifier has a fault of some type. I hope this helps your understanding.
Wow! Thank you. So easily explained. I ran to my o-scope immediately to practice what you just taught me as a beginner hobbyist.
You're very welcome!
This is an excellent teaching. Your explanation was presented differently than most and this led to new learning for me. Good for you! Also, using actual AC and DC supplies and displaying them separately and together on the scope made the subject much more understandable than just the typical spoken lecture. Three cheers for you!
Thank you for your great explanations, you are well-spoken and logical. I watch one of your videos every day.
best regards and special thanks
Thanks Haseeb. Now i understand.
it is my pleasure
learned a lot about oscilloscope, thanks for sharing
best regards and special thanks
Thank you for doing this. It really helps to me understand.
mil gracias amigo, desde México
Very good explanation.
it is my pleasure
it is very well explained 👏🙏🏻👍👋👋
best regards and special thanks
Very helpful.....many thanks.
You're welcome!
Very good and useful information sir thanks for sharing this knowledge to us
Very clear explanation sir
very educative thank you regards
You are welcome
Great Video. Thank you.
Excellent thanks for sharing
it is my pleasure
Thank you.
You're welcome!
super like so great very useful sahring great explanation best wishes
GOOD TICHING KARTE HO AP THANKS 👌🌹👌🌹😆😂😆

Shukriya Maestro. You just answered many questions thanks again
wow great
best regards
👌👌👌👍
so nice of you dear brother
yesssss is good
best regards 💕❤️❤️
Watched a video showing DC coupling with sawtooth via a function generator, but when switch to Ground coupling the baseline aligned immediately on the Zero Volt baseline of the DC Zero volt line. Yours as well as mine does not do that. I do not understand how to get it to align.
Very nice & simple explanation .i always like your simplification of concepts, its simply wonderful.
Sir can we get ac leakage in smps supply dc out put ?
What is practical usage of ground coupling?
1. it is used to calibrate the oscilloscope
2. and it is to verify the trace-line position, when a signal is connected, and we want to verify the exact value of the signal. at time, switching to ground coupling, gives the trace zero line and when we switch back to signal value, we become to know the signal actual value
@@HaseebElectronics Ok, thanks for explanation.
@@HaseebElectronics will be much appreciated, if u show some practical example for GND coupling in videos.
Great work can you do a video on checking the dc offset voltage on a op-amp so many fake op-amps out there
What capacitor value I have to Add
Sir can you help to resolve my DSO REGOL 1052E
The problem is one Chanel showing some voltage without connecting any probe to it.
Second Chanel is working fine.
What can be the problem?
Please help to troubleshoot.
Aslam o alikam sir computer power supply on hoty he off ho jati ha .
please check its output section (capacitors specially)
check smps supervisor IC section
