EEVblog #44 Part 1 - Logic Analyzer Tutorial

[TheEPROM9]

Thank's for this, came in handy for my computing course.

Хоть бы включил его! На бумаге и я могу....

[KeithWasHere1]

so how would i use a logic analyzer or O-scope to find the color change shift rate or pulse rate(red green blue) of a DLP chip? (DIGITAL LIGHT PROCESSOR)?

[KeithWasHere1]

im thinking of getting a Fluke scope meter would you recommend one of these? and what are its limitations?

I'm a lucky owner of Agilent 16901A with 16M x 2 but honestly I still missing my Chinese good quality USB analyzer (for ~1k USD) unfortunely I sent this as gift to my friend after get this new big "animal" from Agilent this is so powerfull for fpga etc. design but totally suck when sometimes I need sniff\debug RS232 I2C etc. things which can be done for UART with my old Chinese analyzer and built plugins in 10seconds with Agilent need so complicate magic. too modern design more for DDR etc.

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.

Wow, this is awesome! Dave's always great at distilling complex stuff down for me. Thanks!

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!

I'm an avionics tech student, despite the move to flying networks, the sad fact is that few schools go even to this much information. I so very much appreciate this education. Thank You EE down under. Congrats to Aussies for implementing ADS-B!

Thank you for the tutorials. Very very very much appreciated.

Say, Dave, you sound like you have a very strong passion for electronics. Just curious, did you come from another line of work that wasn't electronics-related? In my teens, I wanted to become an airline pilot, but I am far from that.

[EEVblog]

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

@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

[rodstartube]

@TheAgentAR why do you ask him that?

[quantomic1106]

@TheAgentAR Hey! same here :)

[stormbytes]

Love your vids man! Count me in..

[19916718514]

very informative , like always.Thanks!!

[Afrotechmods]

Nice one - look forward to part 2 :)

[davidbball13]

hey great video. For some reason the quality is very very poor compared to you're other ones.

[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.

[davidbball13]

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!

[GalaticTG]

what i do is i set it to "private" until I get the HD tag then set it to "public"

[EEVblog]

Ah, yes, that should do the trick, thanks.
