Keysight FFT vs Siglent vs GW Instek  

Thank you very much for the demonstrartion! Every scope has got it's benefits and you did point them out very good

This video is so cool! I appreciate how you go through all the features of the scopes to view the FFT of the wave. You are very detailed and it's helpful for a beginner. I appreciated the use of each window for frequency or amplitude

Hi Eddie, very productive video, Thank you.

Thank you for the video! I decided to buy a DSOX1202A.

Hi and Merry Christmas! Thanks to you, I gained the knowledge to buy my first scope. Got a Siglent SDS 2202X-E. I wanted to make sure I do not grow out the first scope to fast. I was surprised how small it it. I also acquired a signal generator and power supply from Siglent. Unfortunately, the power supply is DOA. Kind of concerning. I fed the scope with a square wave and fired up the FFT. Came up fast and looks good but still need to learn how to adjust the screen and complete measurements. I found a Bode Plot button. I thought that was a SA function? Thanks for the videos and keep them coming. I am going to try to reproduce your AB amplifier video. Thanks, Brad

Informative and very interesting 🤔 🙏

Very very interesting!! Thanks!!!

takes me back many years to the 60's when I went to electronic schools in the USN. One fact a square wave is made of many old hamonics of the first signal. Also worked on a computer that used delay line magnostrictive memory. The computer used a 24 bit word. with the first bits called guard bits (but we called them goof bits. Used a hp time delay scope to read the words on the screen for diagnostics.

Eddie, again great video and postproduction improvements. According to your knowledge and ability to share it in proper way, I’ll suggest you to do some oscilloscope video series where you will cover scope functions in practical way/real world usage. Mostly, videos that treat the theme are “introduction to the oscilloscope” (AFG connected to one or more channels with Edge triggering - Auto mode and cursor measuring, and that’s it )but not many with explanation about: How to independently trigger two or more channels- alternate trigger When to use trigger hold off Why Auto trigger is bad option when processing serial communication, When Normal mode is great option, or how RUNT can prevent headache :), pulse trigger etc.. How to find glitches in signal. Than maybe to explain measuring: What is Mean, RMS, Cycle RMS etc.. and what they tell us. Connect: some analog sensor-> MCU -> PC and show us Oscilloscope in the whole glory:) A lot of youngsters told me that they tried to learn about scope from Kangaroo Dave but, with his flying fingers all over the scope and mouth rapid fire all they’ve got is brain hurts. You are different and you can do it understandable.

Thanks Eddie 😀

Great demonstration of the difference of FFT usage at every scope. About your editing in this video: I think you have made a fine jump forward in quality, your idea with using the red comment bars is a great help, wary easy to see and read and looks more professional, also the fact that you place them where they cover least of what is important on the screen. I do also really like the way you have cut your zooms. I.e. at 7:19 you make it almost invisible that you go from moving the camera to a proper framing of the scoops screen. Then about the length of your video, if you have to demonstrate three scopes in the level of details you do here, I can't see how you could do it in a shorter time. Only thing may be that it did look a bit like you used some time to search and learn the scopes, while making this video. Maybe a plan on what you did want to demonstrate at one scope, copied out to every scope, could have made it more consistent. It would have made your planning time a fair bit longer but made your recording and editing way more easy. All in all do I think you are getting better and your experimenting, do pay off! :-) Last do I like that you did mention your patreon, in a subtle way but still so that people know you have one, it's only by repeating you get more to support you. :-)

I need some advice. I have a Siglent 200mhz 2gs scope. I also purchased a Rigol SA. I intended to send the Rigol back, sell the Siglent and buy the same Instek MDO you have. The Instek MDO is not available till early March, only the 100 mhz scopes are available. I am now thinking about keeping the scope and Rigol SA. Its overall more expensive but at least I have them. The Siglent has BODE functionality using a sig gen. I think I asked this before but could not locate the question. Is BODE the same as FRA in the Instek? Do I lose FRA if I keep the Siglent and Rigol SA?

Eddie can you show how you measure and save the inrush current peak from Power supply and get the value back on screen ? With The GWInstek? Thanks in advance

Interesting video Eddie. I'd give it a go on my Siglent 1104X-E for you but I don't have a waveform generator unfortunately. I see someone called Florin has tried it on theirs with good results.

Im a commercial refrigeration service tech. Too bad thers no need to use oscilloscopes in our trade, it definitely would make me look smarter. Untill then i use it just 4 fun. Thank you for all your work.

Is a Bode plot possible using a spectrum Analyzer? Can you show the SA in use on the Instek 2204EG?

Hi Eddie, I like your videos. I just checked your videos and got me an Instek oscilloscope. Thanks. I'm still looking for an arbitrary waveform generator. Would you have recommendations below 300US$? Many thanks

Thanks for the video! Can you get a board/project that isn't working and show how the less expensive scope work compared to more expensive scope? Thanks again!

Does some entry or intermediate level DSO have a FFT function with calculation like THD, THD + N and the basic 5, 6 calculations for measuring of analog audio signals / 20 hz to 20Khz and bandwidth of 200 Mhz? I have an entry level Hantek and looking for a model with a better FFT func. Thank you fot this video

FYI Kiss: Link provided in "MORE" for Amazon is not valid. I think Amazon no longer carries Keysight. Keysight probably thought it was not very "prestigious" for their scopes to be available on Amazon, i.e. it "cheapens" the brand name.

I have a few questions we see a lot of noise Is it noise from the source or from the scope ( fase )noise of the scope ? The noise floor on 80 dB is a 20 dB beter then the old spectrumanalyzers 60 dB was great the bumps between the odd Harmonics are that the even Harmonics Why are the not dropping down like the odd ? The noise can be canceld out for a few dB so more then 80 dB dynamic range Another question is how close in freqency can you put a second signal and strength ? Without making signals in the analyzer Thanks in advance for your answer And what a lucky guys are we today , My old Takeda Riken Spectrumanalyzer I sold it for about 50 cts a KG weighed about 60KG and now about 2 kg

Eddie...did you ever figure out why the Siglent scope was showing incorrect Vrms in FFT mode?

I have a Siglent SDS 1202X-E and everything it's ok... I just tried and it works very well on Vrms too, just like on dBVrms. Maybe you need to update the firmware, I don't know... it's possible to be the software issue, when math computing chip inside, takes the levels from input stage, on different units and scales, who knows... You should try update the firmware.

Does the Instek have a 50 Ohm input selection?

Sorry couldn't watch . . . I'd be too bummed . . . after going back to my old analog BK. Watched your video on the x-over review made on your O-scope and it left me wanting a new scope. (It's like watching a video of someone who owns one of the 427 Cobras . . . just hearing them idle is orgasmic.)

Fred or is it Eddy ? Have a email from GWInstek Since we need to consider a multi-language selection of the display, all selection icon for each language is not allowed to over the frame range. So far we already provide the biggest font on the DSO including the MDO-2000E series.

Thank you ! It was very interesting. Btw, you look like James Hetfield from "Metallica" !

what's your summary or conclusion? thanks

Eddie isn't stupid But he also have to practice to show us the power and possibilities of this scope,s Almost every time i used it , i get lost into menus , looking on wrong place on the screen and happy with the default button , on the end I Win the battle 😅

I got a lot more learning to do

Too many cycles gave you too MANY points - thus the "snow" look.

it would be better to give summary first, video tooooooooooooooooooooooooooooooo long!
