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"! -- Rick C. - Get 1,000 miles of free Supercharging - Tesla referral code - https://ts.la/richard11209

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. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209

Like 'don't reverse > the polarity'.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. MKE

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... Chris

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. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209
