That's because you are too keen to view it! It takes time (maybe 30 minutes) for the video to process after I finish uploading it, the quality is quite poor until this is done. It should say this above the video. I don't know why CZcams allow people to view it before it has finished processing.
@EEVblog LOL I burned my hand when I was 4 years old when I played with a 110V AC lamp every time I moved the wire I got some sparks one day I get it, after that I can't stay away from PCB, PS, AMP, PC, TV, etc... aslo I m EE, and I really appreciate your work thanks for the gift
Well, if I was going to watch one video tutorial on an electronics related matter, I couldn't think of anyone I'd have expected to make a better on than Dave.
Thank you for the video. I saw another video about your project in 1996 and I was puzzled "what is a logic analyzer?" (as a casual viewer that likes to see but has no electronic experience). The sentence "a 32 channle binary oscilloscope" makes it greats. But yeah it should be pretty tedious to connect all the 32 probes on the thing. I can see why people go for oscilloscopes.
(2019) just picked up and cleaned out my very own HP 16500B. My hobby is old laptops, got this to help me analyze and repair problems, plus at the time it was the only oscilloscope near me on the used market. Btw I'm new to the game
I recently picked up a HP 1660as 136 ch logic analyzer/oscilloscope mainly for use as a scope. And boy is it a heavy scope. even came with the training board and floppy plus a mouse and random accessories. And alot more channels than I most likely to ever needbut it's alot better than my old scope a analog Goldstar 20mhz scope.
Thanks Dave! You just saved me a few clams. I was looking at a very clean HP 1630 for 50 bucks, thinking how sexy it would look on my kitchen table / electronics bench. But eventually someone will ask what does that do? Then I'll have to answer "well, it's the same thing as a deer with no eyes... No ideer. ;)
Hi Dave, Logic Analyzers address the needs of hardware and software. Providing the options of mainly state or timing. A deep memory oscilloscope will not be that useful to a software engineer writing device drivers. To debug firmware state information displayed in both timing and instruction (hex and symbol) is needed to debug. Also, for debug a special extended version of the PCB would support plugging in the channels 16 or 32 bits at a time with proper termination.
Hey Dave. On the last subject you talked about compressing data. Is there any practical reason not to? It seems pretty obvious for a digital-only device not to waste space like that, even because this kind of compression wouldn't even require much processing power. I know it might be tightly related to the product's design, but would you design one, for what reason would you not trivially choose compression (again, digital-only) ?
Hi Dave, Quick question, is there any logic analyzer which can playback the captured data. So lets say we captured data from a microcontroller and then remove the microcontroller and playback the software to emulate for that same microcontroller?
Great post, but I believe that the Logic Analyzer, or even a MSO is the digital design engineer's best friend. I've been working with DSPs and FPGAs for quite some time now. Not all chips have cheap debuggers/emulators. Scopes only have couple of channels which are "too noble" to deal with simple 0-1 logic. If you're designing a circuit with a bus or complex digital signals, you should definately get a logic analyzer!
hi sir very nice and interesting video I would be very happy if you can help me there are lots of confusion what is most better than we can use in all repair work oscilloscope or logic analyser

I am from the future (2019),
hello to young Dave with big round goofy eyes !
This is the best chanel for electric engineer, embedded designer, and computer programmer.
Pretty refreshing to hear this guy not complaining about something for a change.

My favorite aussie CZcams channel, hello from Melbourne :)
#44... Wow! 😮🙂
I've been subscribed for a few years now, but when I searched for "Using a Logic Analyzer", this video was at the top of the ranking!
Anamnesia same here :D
Well, if I was going to watch one video tutorial on an electronics related matter, I couldn't think of anyone I'd have expected to make a better on than Dave.
Nope, been doing electronics since I was 8, never had a non-electronics job.
10 years difference but somehow it seems that you were as great then as now. Except your camera setup is better.
Even your mic was really good.

Nice one - look forward to part 2 :)
where is the part 2?
Thanks for explaining this in detail!
this guy knows a lot. this is the eleventh time i have come here

I did not know youtube put the video up before it is finished processing it. That is odd....Well another great video! Keep 'em coming!
Geee how time flies... i just ordered a: USB Logic Analyzer 24MHZ 8 Channel 12C UART SPI IIC CAN 1Wire Debug For ARM FPGA for about $10, any comments?
Ah, yes, that should do the trick, thanks.

immer super
Thanks, this helped! or cofused even more ;D
Dave, can you do a review on a Saleae Logic analyzers ?

Soooo, how would you update this video..
Aaaand
What of the equipment in the background is still in use ? :-)
good tutorial. thank you.
excellent content!
I think 'compression sampling' used to be identified, in logic analyzer specs, by the ability to 'time stamp' each sample.
eevblog you are a combi scope mate
The times have changed for pricing very much since this video was made
Oh man, I thought I was onto a cheap oscilloscope alternative here, but looks like it's still like flying blind
can any of these be used to decode the logic of a cpld chip?
hi sir very nice and interesting video I would be very happy if you can help me
there are lots of confusion
what is most better than we can use in all repair work
oscilloscope or logic analyser
hay,can you please recommend on USB logic analyzer 4 channel up to 80$
Oscium does some great digital oscilloscopes and digital analyzers using your ipad and iphone =)
Do you age Dave?
what i do is i set it to "private" until I get the HD tag then set it to "public"
Logic analyser, Bah! Use your tongue.
Transistor to Tongue Logic, Nice MOS - Pain MOS - Complementary MOS, Emitter Coupled Licking
Main advantage is that for $10 to $20 on ebay you can see what your signals are doing ;)
+Digger D This is 7 years old remember!
trippy bass .
@TheAgentAR why do you ask him that?
He already did one, search "eevblog saleae"
@TheAgentAR Hey! same here :)
hey great video. For some reason the quality is very very poor compared to you're other ones.
mhhh you did just fire my interest in engineering
I got one for $4. It's about the size of a pack of gum.
Wrong explained. Compression sampling must store timestamp at each event (4 or 8 bytes). Synchronous sampling stores 1 bit at each sample.
i have learned so much from your videos it's not even funny. Very selfless of you
logic analyzer is just 2bits adc
Good video but pretty rudimentary.
+Frank S Were you hoping to get a degree after?
Putins Cat no, been using la's for many years
Frank S Many years yet watching a "rudimentary" video hmmm ok
