they just need something to space out the ads, the article was written by a
\"Solution Architect for Battery Testing, Electronic Industrial Solutions Group, at Keysight Technologies. \"

The guy works at _Keysight_. \"How are the mighty fallen.\" Or maybe

I\'ll bet that \"solution architect\" has a performance review objective,
and ED hasn\'t got much source material to choose from.

The old concept of \"least publishable unit\" is alive and kicking

I also love the ritual \"11 myths about...\" and \"What you need to know
about...\" and lectures about how hard electronics is.

I wonder how he got that crud into his DVM. Maybe a month in the trash
under a freeway overpass? Maybe his office still has gas lighting.

Rofl, such contempt . Last time I checked, a lot of
Keysight test gear was running Windoze under the hood,
not even embedded Linux, or a real time os like VxWorks.

Old and quality HP test gear, such as the 16700 analysers,
were running HP-UX and you could ssh login into a unix
shell with a few tweaks, or even point a browser at it
for remote display.

Still, I guess their lunch is being eaten by China IP
ripoff tactics. How can they complete with such prices ?.
Use home grown or lose it...

Back when, I had a short email exchange with Bob Pease about one of my
greatest inventions (or least pitiful inventions). He liked it enough to
show his brother or somebody. But then I babbled on about \"Electronic
Design\" being better named \"Electronics Design\". I just love to
(unintentionally) annoy authority.

\"Real time\"??? I used it on a project with an embedded small form factor PC. There was an OS call to do something simple that didn\'t return for over 400 uS! We contacted support about this long time and the response, once we got one, was that function has been in use for years and it has no bugs!

Don\'t even call VxWorks \"real time\"!

It\'s hard to believe that this is a serious article.

I don\'t get why everyone is dissing this article. It\'s a bit lightweight, but he is simply pointing out something that might not occur to some, that a battery can be discharged when monitored long enough, especially when the electronics in the voltmeter is contaminated by dust, or in particular, carbon dust.

I\'ve never needed to monitor a battery long enough that the measurement current would amount to anything and I have no idea at what time span I might need to give it attention. More importantly it would not occur to me to check the insides of my equipment before starting such a test. That was the point I got from the article. Pretty much all of my equipment is over 30 years old... well, any that I trust. It\'s probably all due for some internal cleaning.

Well, IMHO the point is one that might appropriately be made in

If there is an EE out there doing electronics design that got any new insight out of this article...I am glad it is not my job to review their \"designs\".

ED has been garbage for a while.

It took a while, but the web has killed almost all of the decent trade publications - now that the average attention span tolerates a single scroll of the screen. Most of these rags are ghosts that don\'t yet realize they are dead.

I do like Paul Rako\'s stuff a lot - the rest of ED I can generally do without.

\"Real time\"??? I used it on a project with an embedded small form factor PC. There was an OS call to do something simple that didn\'t return for over 400 uS! We contacted support about this long time and the response, once we got one, was that function has been in use for years and it has no bugs!

Don\'t even call VxWorks \"real time\"!

That suggests poor system design, but it depends on what the function
was doing and host of other variables. Having worked on several rtos
and vxworks projects in the past, it qualifies for the name real time,
but good system design is essential to get the best from any sharp
tool. Anyway this was a critical thread about Keysight and the
comments look pretty accurate to me...

I don\'t recall the exact function, but it was something to do with scheduling or checking a semaphore. I just remember that we used a logic analyzer to measure the timing and was very surprised that support wouldn\'t even discuss what was going on. The person on the phone was just a person capable of answering the phone. We got our response and could now shove off!

Even if the response time of the software was adequate, the response time of the company was not.
