Good job at pointing out some of the differences. I don't think the advantages of the digital scope are as marked as you say they are in the example from about 8:20 to 13:15 (burst of three cycles at low frequency). You can move the display of the wave form around on the analog scope, which you actually did at about 13:10 by adjusting the trigger. I also wonder if you could reduce the flicker with some adjustments. About measurements, I'm thinking that the digital scope may not have an advantage in accuracy if you're using the cursors. Positioning the cursors is not exact, so there's inaccuracy there. On the other hand, it's nice to have a digital readout rather than having to count squares on the grid. To me the big advantages of digital are the abilities to store a waveform (send it to computer, print it out, etc.) and to see transient events. But I'm new to this and I've got a lot to learn!
Thanks Jacob. When I was studying electronics in the late 1980's, we used Tektronix analog scopes. It is nice that the modern digital storage scopes, make life a lot easier for us, in the tech field. I always appreciate practical knowledge, when it pertains to a complex subject!
Thank You! It was very informative and helpful for me - I just started to learn to use scopes and I own HP54600B scope. Just recently I got another - fully analog Tektronix 2445A and, used to HP display I thought it was broken at low frequencies :D Now I know It works just as it should so I'm relieved :)
Thank you for making this video. It helped me to find out that I was going to get the wrong scope. DSO scope is what I need,(and got now). I almost wasted money I don't have to waste. Thank you
Very good video, except for one inaccuracy: the comments about graticule measurements/cursors weren’t entirely correct. Higher end analog scopes have cursors just like on your DSO. And although reading measurements from a graticule can be time consuming, on a properly calibrated analog scope, the measurements will be just as accurate in nearly all cases as a DSO with automatic measurements.
PLEASE do a video on all the features of that 2230. There are no videos on RUclips explaining the entire UI of that scope. I'll sub just incase you decide to!
Hahaha. I actually see it better on the bottom scope. The freeze frame or capture is nice if you need to fiddle with knobs, but I can actually see what I need on the bottom analog scope...nice
The bottom scope has the intensity turned up higher. Jacob could have turned up the intensity on the top one to match but chose not to. This is not a real difference between these two scopes.
1/2piLC would be the frequency of an ideal LC, an attenuated oscillator always has a slightly lower frequency ;) just kidding. Great video. Id love to see more about the 2230. Awesome Tek scope. Subbed!
DSOs are definitely good for transients. Also, nothing is "projected" on the screen. The CRT emits a beam of electrons that hit the phosphor coating on the inside of the tube "screen" and causes the phosphorous to release energy in the form of light.
It’s elf,example… not useless just use more than one cycle. Also if you badly want to capture an “event” record the screen with external device. Back in a day we used to take photos.
are there extra8/addon/separate memory modules for an analog osciloscope? like a kind of equipment to add into the dialling between the generator and the scope it self so that it could store the signal and cover the lack of memory on behalf of the analog osciloscope?
I still don't understand why its starts flickering when you zoom out of the 60Hz signal. I have the same results on my Analog Scope at 60Hz and lower frequencies. At high frequencies it has no problems. Can anyone explain? thanks!
My confusion still is how a digital scope is useless vs an analog scope when watching audio waveforms or x/y mode. The sample rate on a digital scope is too slow. And if that’s the case isn’t a digital scope losing data since it can’t keep up? That’s where I’m still confused. The sample rate vs the bandwidth I suppose.
the dude in the video uses a super early digital scope. modern ones are NOTHING like the one shown here. Sample rates now go into the Double digit GIGASAMPLES range on the higher end ones.
Nice video, but I don’t really think it is helpful for someone looking to buy an oscilloscope today, reason being that the example you are using as a “digital” oscilloscope is really an antique, late 1980’s and is one of the very earliest generation of DSO’s ever made. Any more recent digital scope is going to look and behave vastly differently. You mentioned the replacement of the Cathode Ray Tube with an LCD, but there is a more important difference in the user interface: On modern scopes there are no numbers or cursors or absolute positions on any of the knobs. The mechanical knobs have been replaced by encoding wheels, and all values are read off the screen itself. That change was easy for me when I transitioned to digital scopes 20 years ago, but today when I’m faced with an analog machine I’m a bit thrown off - though that could just be because I’m 20 years older!
I'm about to get my first oscilloscope. Do I purchase a used eBay scope like the Tektronix 2230 or go for something more modern with a non crt display? I don't want to spend more than $200
Jason Lome if you want to keep it under 200 go with a used tektronix. You won't find a good modern scope for less than 400 I would argue the rigol ds1054z is the best modern budget scope coming in at 400. Start with a used tek. They are great ways to learn the scope before moving to a modern scope.
@@lomerangeryes. you can view slower signals, have automatic meassurements, have cursors, capture one time events easily. and capture slow events, a digital scope is just better. get an owon sds 1102.
beware that this dude is using an ANCHIENT digital scope, yes its insanely different. modern ones are so much faster, so much better, its like comparing flint and steel to a lighter.
@@fullwaverecked They almost always display at a higher refresh rate, and the x-y mode is actually useful. However, the downsides of the analog scope are huge. No single sweep and good measuring really makes the thing stuck in the past. My favorite tool is the analog/digital hybrid scope, particularly the phillips/fluke pm33xx series.
Please don't touch the graticule with the sharp objects, it hurts
I'm just learning about oscilloscopes with the intention of buying my first scope and this was super helpful, thanks.
@Nasir Salvatore Definitely, I've been using Flixzone for since december myself :D

Second that. A great scope; it deserves an instructional video.
Third that
you guys found a video about that yet?
lol i agree too!
A very good video emphasizing the benefits of a Digital Storage Oscilloscope as compared to a completely analog oscilloscope.
Well there are analog storage oscilloscopes.
you brightened my day I have a Tektronix 2220 Digital storage
Hahaha. I actually see it better on the bottom scope. The freeze frame or capture is nice if you need to fiddle with knobs, but I can actually see what I need on the bottom analog scope...nice

Capturing a single trace at around 4mS of an inductive ring is pretty cool..
Kid, don't touch the screen on the oscilloscope.
why?
Why?
it fucks up the glass, also crts produce electric charges.

Love those old storage scopes
Thanks for making such a great video, I'd learned a lot!!
as someone who has only used analog 'scopes; the capabilities of the digital storage 'scope is astounding. i'll have to get myself one at some point.
Do you know if there are any good videos on the actual technicalities of oscilloscopes?
Great video, thanks
are there extra8/addon/separate memory modules for an analog osciloscope? like a kind of equipment to add into the dialling between the generator and the scope it self so that it could store the signal and cover the lack of memory on behalf of the analog osciloscope?
yes it is possible but at that Point you are building a digital scope, so might aswell ditch the analog part, and the crt.
@@SimonBauer7 interesting, what is it caled that kind of device?
You can make a video of your oscilloscope with your phone and get 90% of the functionality of a digital scope.
Isn’t technology great?
That’s what I do…and old analog scope are super cheap.
great vid bro!

and then there are usb scopes, that you can operate from a pc. or ones with Touch screen
But can it play Asteroids?
