How to measure Harmonic Distortion with Siglent Oscilloscope
Вставка
- Опубліковано 3 жов 2024
- This video shows the setup to measure Harmonic Distortion with a Siglent Oscilloscope. I show a similar setup to what JohnAudioTech uses in his great videos. He now has a new Siglent Oscilloscope to use and I thought I'd show how to setup that scope to take his measurements.
Let them know I sent you - that would be so awesome;)

Excellent video!! Love how you get to the good points!!! Keep them coming!!! Thanks so much for Sharing your wealth of knowledge!!!
Thank you - I appreciate you!!
JohnAudio does EXCELLENT videos no doubt but I was wondering about the same video that John did and how the Siglent could look that bad. I was thinking of buying the new Siglent but saw that video and slammed the brakes on. The I saw this video, and restored my faith in the Siglent scope! Thanks.
Harold Lacadie Yes I like John’s videos too. I think in his video he made the mistake of setting up the Siglent with the same settings as his Rigol. I made this video after he got his new scope because I had a couple of subscribers ask me to show him how to setup his scope, but I don’t think he watched it;) I think he just needs to change the time base to capture more cycles.
I really needed this. Thanks. Would love more videos on amps and maybe effect pedals.
That’s great - thank you!
Nicley done Eddie,
It took me over a week, to figure that out on my siglent scope :)
ATB Adam
Thanks Adam - having the other scope to compare shortened my time;)
I am impressed! This video is technical the best you have done to date! You do just tell all the way with energy, no pauses where it did sound as you just remembered you forgot a thing. You just nailed it this time!
Your editing was also great! Smart detail when we did look at the scope, that you did cut while your hand were out of the picture, it did just made it look like your scope updated the screen and not like a cut at all:-)
In short, as I did say in the start, your absolute best produced video to date!! :-)
Fried Mule Thank you so much! I feel like I should retire and quit on top - I can only fall from here;) I have learned a lot from your coaching and I really appreciate it! I hope to surprise you again one day - so I’ll keep at it;)
@@KissAnalog LOL no no, you do not get away that easy! :-) I am very happy that you can use my comments, your videos means a lot to me, without them, would I still have to find about 90% of what I know from you! :-)
That’s very nice - I appreciate you!
The Siglent scopes are excellent for the money - easy to use, nicely laid out, good resolution. I'd recommend one any day of the week. Nice tutorial to show the set up of FFT - some of these features are hard to get to grips with. Hard to understand what it's showing and how to interpret as well TBH!
Thanks Andrew - great to hear from you! I need to cover more of the features;)
This stuff is so useful as I just bought this scope for slightly better specs....cheers.
Thanks for the feedback! Which scope model did you get?
@@KissAnalog SDS1202x-E, getting to grips with it now !
Ok that's a great scope! I've used that one too - and some of the operations are just a bit different than mine. It seems obvious to me that there was a different firmware engineer writing code;)
I got the x-e 200 MHz it's a lot of scope I really wouldn't call it an entry level scope . As always a great video .
Robert Hicks I totally agree - it is so much more scope than what we could have hoped for at much higher prices 10 years ago. Thank you!
I bought a siglent sds1104x-e oscilloscope as my first scope. I was thinking about the rigol 1054z but the siglent was 50€more and a bought it because of the hier bandwidth. I never thought I'm gonna use fft but now I spent half of the time with fft on I really love the resolution and for audio level measurements it's fantastic
I only use dbv so I don't know if my scope has the same problem
The B Clash Gamers Clash That’s great to hear! Let us know any tips or tricks that you might have;)
Maybe updating my firmware will do the trick?
I wish I have this scope. Great video!! Thank you!!!
Yes Fernando - these are great scopes. Maybe you can win one some day;)
@@KissAnalog ohh... maybe. We are poor here in south America LOL!!. Thanks!!!
I will be giving away some multimeters, and hopefully scopes too. What country are you in?
Hi 💋, this was a great video. Thanks a lot for a nice demonstration. Stay safe.
versace885 Thank you and I appreciate your support!
Eddie, please make a video about yourself - It is interesting whats your background , where did you gain all this knowledge etc.
Ok I can do that, thanks for suggesting it. I guess on one hand I might not have thought that would be of interest but on the other hand I could see where my credentials might be of interest.
A great introduction.. Thank you !!🙏
Thanks for the support!
Nice DEMO 👍👍
Thank you! Cheers!
Thanks, This is pretty useful. I also have a lower end Rigol. I think it is 1 series after what John has. It’s not bad but the FFT leaves something to be desired. The free computer based spectrum analyzer I use actually has way more detail than my scope in FFT.
Thanks Tron! What is that software? Maybe you told me about it. I need to try one.
@@KissAnalog www.sillanumsoft.org. I ordered this to bring the high level signal from the amp back down to line level so it doesn’t blow out your mic in jack on your computer www.crutchfield.com/S-oSIQYjDvJIP/p_543ADP12/Russound-ADP-1-2-Speaker-level-to-Line-level-Adapter.html?XVINQ=GLX&awkw=78572876905&awat=pla&awnw=g&awcr=50190041905&awdv=m&awug=1025197&gclid=CjwKCAiAo5qABhBdEiwAOtGmbm1eaqpTXIwnhdu30fCF8oy4M2HB_a2ULuz5naKbDt8uUE0UMv80CRoCF8QQAvD_BwE
You can also use a oscilloscope probe at the 10x setting. With a bnc to aux converter. The software has a oscilloscope and spectrum analyzer plus Thd measurement.
Eddie, great video content as always but you need to reduce the intro fluff (1-2min should suffice) for your videos.
Thank you! I will try to get more efficient with time;)
Thanks, Eddie! My SDS1204X-E has 1Mpts FFT.
Robert Calk Jr. That is so sweet! And some with an Australian accent might call it an entry level.... wow we have really raised the bar:)
@@KissAnalog Yeah, a rich guy would consider it an entry level scope.
Yeah it is based more on what it cost instead of what it does;)
Brad suggested this and I said Bert - sorry it was late;)
John mAudioTech’s latest video
ua-cam.com/video/bRDiD3BM7OA/v-deo.html
ha ha, thats OK. I had trouble with the Siglent FFT as well. I wrote it of as inexperience but had no trouble with the Instek. Awesome job!
Thank you Brad!
I have the HP 141a ocliscope and the 85632/85533 if and RF anylyzer plus the 1202xe plus another ..justvwondering if the fft would out preform the analyzer.
There are some advantages of the 1202xe of course, but the noise level in the BW of the HP is going to be lower than the 8 bit scope. The Picoscope with the higher bit count would give the HP a better race;)
Could you elaborate a little on why you did you hooked up a second generator @18:45 ?
You bet! That is a great idea - I need to give a much better explanation on this.
Good job sir! Thanks for informative video!
BTW - doest that KUNKIN load have some PC interface to maybe log data of voltage and current of discharge?
Im looking for solution to track both that parameters - or maybe there are some benchtop multimeter that allows to track current and voltage and log data?
I think it does, but I haven’t tried the software yet. I’ll let you know also there are some meters that can log. I’ll check on that too. Thanks for these great questions!
I think the firmware must be different, the 1202X-E I have the menus are totally different. Seemed useful though.
give us a link to John`s video!
I just added the link to my pinned comment;) thank you for reminding me. I’ll put it in the notes for the video when I get to my computer ;)
Hi. Will GW be able to measure THD less than 0.1% ?
The scope you were talking about was behind your back and you didn’t say what model it was. Just a comment. 👍
Sorry about that;) It is the Siglent SDS1202X. And then there’s my GW Instek MDO-2204EG
notch filter and turn up scale
Thanks for your feedback!
You lost me on the part where all the probes are hooked together. Most of the rest I understood. It would like you to teach us how to do the hook up to the signal.
Ferniez sorry about that. My videos get so long - I make short cuts;) they are just all connected together. So, the two generators are tied together and both oscilloscopes are tied there as well as the Keithley THD meter.
It's not just being slow because it's slow due to the signal being slow
Kris Ankers Yes - you are so right! Thank you for pointing this out;) It is pretty impressive for what some refer to as an entry level! I
This would have been king 10 years ago. Thank you for bringing this important point up!
James Hetfield of Metallica teaches people how to use a scope.
LOL thanks!
11：45 start
Thank you!
Skip all the blah, blah, blah and go to 11:57
Fair enough;)
You wasted my time - to much
loose talk - bemore conentrated in the future and take time for the things you want to show.
Sorry about that. I hope it was still useful, and maybe it will save you back time if you did...
