EEVblog #44 Part 1 - Logic Analyzer Tutorial

Dave gives you the what, how, and why of Logic Analyzers.

[EEVblog]

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 Youtube allow people to view it before it has finished processing.

This is the best chanel for electric engineer, embedded designer, and computer programmer.

hello to young Dave with big round goofy eyes !

@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

[EEVblog]

Nope, been doing electronics since I was 8, never had a non-electronics job.

Pretty refreshing to hear this guy not complaining about something for a change.

[Choober]

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.

[nonicnik]

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.

#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!

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.

(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

[MegaGreenman]

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.

[metaltyphoon]

Dave, can you do a review on a Saleae Logic analyzers ?

[fullwaverecked]

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. ;)

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) ?

[electrifyingelectron]

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?

[PsiQ]

Soooo, how would you update this video..
Aaaand
What of the equipment in the background is still in use ? :-)

[THETHPHANTOM]

this guy knows a lot. this is the eleventh time i have come here
