Ohh, you have to get the Siglent arbitrary waveform generator SDG1032X with this. The scope and the AWG can communicate over ethernet to create bode-plots of phase and amplitude. Absolutely insane and game-changing for audio circuit design and analysis.
I just got this exact scope this passing Christmas. Its a great tool for tube amp and guitar pedal building as now I can see so much more what the circuits are actually doing to various waveforms. I haven't tried the FFT math function yet but, as my curiosity is growing that should be coming up soon. I just received a few Opto-isolators from Digikey today that I plan to try for amp mods that might pop loudly if the switching time isn't gradual and having 4 channels will be great, in order to view the LED voltage, R/C voltage slope, voltage across the resistor cell and who knows, maybe I'll find something else to look at with the 4th channel! Thanks for the nice video, and hope you get alot out of your new Siglent!
I love that I bought this scope and the algorithm put this in my feed after some other searches. I notice the channel title. Hi from Dayton! Small world!
Bro why did you make a video about exactly what I needed on the exact equipment I needed it on? Your making browsing for obscure information too easy. (Thanks though I really appreciate the time you put into this!)
I have an answer for that! If I'm trying to learn something, and there isn't a video about that specific thing, I learn it the hard way and then make a video to fill the gap. 🙂
Can I have some more, please. I bought this device a week ago and sat in front of it like a rabbit in front of a snake. It's the first oscilloscope of my life, but I'm very excited and am looking for any information I can get about this device.
I have the 2 channel model (1202). I found the zero offset does not work. All it does is shift the vertical. When I scale the vertical it still scales relative to 0-V and not to my offset-V. Does it work on the 4 channel?
Great video. Sorry if I missed it, but will this allow say ch1 and ch3 to overlay and allow you to compare linearity between the two? For instance, measure input signal on a device and output of same device. Thanks
So far as I know, it is not capable of simultaneously displaying the FFT for two channels. You'd probably have to spend quite a bit more for this functionality; this is an entry-level device, after all. However, it would be quite easy to simply characterize the input to the device under test first, and then characterize its output second. You could then compare harmonic peak amplitudes for relative distortion, for example. You could also use other math functions to help with the observation of differences.... for example, you could subtract the channel observing the input from the channel observing the output, which would show the time domain waveform of the difference.
@Gem City Mastering thanks for the reply👍👍 Seems like a lot of fiddling, but doable, I suppose. I guess a screen shot of both would do it, but non the less, not in real time. Shucks
Why does the x axis of the spectrum ranges from -630 Hz to 19.37 kHz instead of 0-20kHz. Negative frequencies - is this some sort of bug? If these values were selected automatically, is it possible to override manually? Greetings
The answer to this is quite complicated, so I'm not going to get too deeply into it, but essentially, an FFT is just math. When a signal is mathematically divided into its sinusoidal components, you essentially have rotating vectors in a complex plane, where the sign indicates the direction of rotation. Pragmatically, this means that when you do the time-domain to frequency-domain transformation that an FFT does, it creates a mirror image of the data on the other side of zero (negative). TL;DR Anything below zero can be ignored.
@@gemcitymastering Ah i see, the new 4 channel Siglent model must be amongst the top budget scopes overall and definitely a very good upgrade choice. Enjoy!
That is an excellent question. I'm not entirely sure, but this is a 100MHz scope, so I would doubt the FFT performance above about 90MHz, although I'm not currently doing anything near this range, so I'm not certain.
@@cambouiscom yes NTP ist a solution and it works in my case. But you can set manually. And I expected the timer will run also when system down. I think behind is a linux and after restart it loss the values.
I appreciate how you explained why FFT is useful to you, instead of just explaining the functionality of the scope.

Great demo of the 1104X-E. It's a great scope with a lot of features with the latest firmware update.
Cheers!

Had a Fluke portable scope but just got this scope today! The Fluke was good for basic stuff but this is just way more useful! Nice video!
Very helpful - excellent performing and selling scope!
Thanks for watching!
Thanks A Lot! You help me solve my problem, May God Bless you!
I had no idea what FFT even stood for. I had to look it up.
Yeah I just got the same scope. Super nice… too bad I don’t know more… learning as I go but yes, very nice scope.

I was wondering sir, what was your previews scope? Just wanna know to what we are comparing to...
Siglent SDS1102CML.

What's the Maximum MHz the FFT can measure?
That is an excellent question. I'm not entirely sure, but this is a 100MHz scope, so I would doubt the FFT performance above about 90MHz, although I'm not currently doing anything near this range, so I'm not certain.
my scope lost date and time after shutdown. Can you help?
That sounds like perhaps a dead internal battery? Or maybe it is synched to NTP and that got corrupted? Honestly, I have no idea.
@@gemcitymastering works ist in your oscillocope?
@@cambouiscom yes NTP ist a solution and it works in my case. But you can set manually. And I expected the timer will run also when system down. I think behind is a linux and after restart it loss the values.
@@cambouiscom i have wrote an e-mail to support. I got fast an answer but not helpful. But the response time was very good. No I'm waiting.
@@cambouiscom my manual has only 208 pages. But NTP is ok for me. That solutes my requirement.
This thing came up when I was looking to silence my neighbors god awful music. What exactly does this mysterious device do?
This device, and for that matter all oscilloscopes, very simply, display voltage as a function of time.
