I think the title and description are a mistake? Or you uploaded the wrong video?
Fantastic tool. Doesnt replace a scope but should be rhought of as just as critical
What is the major difference between devices like these and oscilloscopes? You mentioned that there's a difference but didn't go into the details. Kindly clarify this point; it will help me understand this better.
I hope I may have this or win this! You may give a review to Hantek logic analyzer and scope some time as they are very low cost. Regards,
It would be interesting to see how this Logic pro compares to Digilent's Analog discovery logic analyzer. I'm interesting in having one of them, but couldn't decide which one to choose. Analog discovery cost $99 for students and $279 for non-academic, which is considerably cheaper than the one you showed.
Great video, thanks.
Mohammed Algailani The Analog Discovery is very nice at $99. I reviewed it here www.ganssle.com/tools.htm.
Jack Ganssle I've read the review, and you mentioned that it is not suitable for ARM development. Actually I'm doing Cortex M4 development side by side with my Spartan 6 FPGA course. That's why I need to know which logic analyzer could provide the best accuracy and better user experience.
Thanks for the link.
What do you think of the Saleae logic 4 and 8. At $100/$200 they seem a great value.
They use the same great software, but (obviously) have less inputs.
Dave McAnulty I have a Logic 8. It's a great tool. My review is here: www.ganssle.com/tools.html.
Hello sir,
What is voltage input range?
Digital levels can be from 1.2 to 3.3+, analog range -10V to +10V. The analog gain is not settable and the the leads aren't designed for low-noise analog probing, so don't expect to measure mV-range signals. Still quite helpful sometimes =)
nice tool
Haha, they'd totally bust you, all of those wires!
Now logic pro 16 channels is $1000US. Too much for my taste. And ordinary non-pro 8 channels is €350EU, that is wrong - cheaper Chinese clone has better USB connector.
Ironically it looks like another piece of software called Logic Pro.
Uhm... Is this the right video? It seems to be a logic analyser rather than a 'scope...?
"pulse widths can be pretty enormous numbers or pretty tiny" huh ? I can't see anything lol no information in this review.
this is a poor tool, only for hobby
Totally, 100% WRONG. As an embedded developer, I get far more use out of logic analyzers like this one than I do oscilloscopes. Why? You get an essentially unlimited capture buffer (limited only by your HD size). I've done captures of hours. You also get an almost unlimited pre-trigger buffer. I've used the analyzer to show me the events leading up to a failure (set a gpio in a fault handler and trigger off of it, then look at the pre-history). Having the protocol decoders, you can export the data and easily write a python program to parse it (eg examining packet traffic). Jack is correct noting that the analog part is not an oscilloscope, it is, however good enough to see signal corruption (device loading, ringing, overshoot, etc...). All in all, I get a ton of use out this logic analyzer.
Well I do know that Apple uses them (for lower speed I/O, etc)... guess they're still a group of hobbyists (ala Woz) that have build a 2 trillion dollar hobby.
It is absolutely not a hobby only tool. Do some research, its excellent for debugging, and prod validation through their automation interface
