DDK from NI

You've probably thought about time stamping the data. I don't know about nano seconds. microseconds should be easy enough.

I once did wired 802.15.4 for prototyping a zigbee chip, basically wired-or on coax

out of the box that should be in sync to within ~60ns at every packet and do ~2Mbit data transfer

Of course there's no collisions in modern Ethernet, just jitter and latency up the wazoo.

It's just a matter of knowing who's boss.

"Industrial Engineering" is fancy name for Operations Research. I am afraid this guy's knowledge of electronics or systems programming is as good as my knowledge of the Chinese language.

I want one that says "Lab Sweet Lab". ;)

The main problem with Labview IMO is that it's as hard to verify and

Dunno. I have a lot of time for real Operations Research folks, though--they specialize in asking the right questions, which surprisingly often leads to the right answers.

For instance, in the Royal Air Force in WW2, some bright spark realized that what they wanted to optimize on was _flying_, not readiness. Starting there, and with the aid of some brass senior enough to knock heads together, they achieved something like a factor of 2 better utilization of aircraft and pilots than they had before.

Not this particular guy, however. :(

Are you referring to the White Rabbit stuff?

That's it! Couldn't remember the name offhand, and Alice wasn't around to ask.

Considering the amount of posting on how bad is NI/Labview combination I would rather toss the card in the garbage bin and aim for a different one.

We need to generate sine/cosine waveforms with a 16bit resolution and

Any idea of a producer which has linux drivers as well? Maybe I can start looking at the comedi website and see their supported hardware. Has anyone used their drivers? Or added extra support for another card? I'd like to see how much effort would require to add support for our card as well.

Anyway, thanks for the ride, it was interesting to see how the post triggered some quite intriguing stories!

A really cool professor taught the Psychology 101 course at Tulane. He'd worked on training issues in WWII.

One day, just before the final live-shoot exams for bomber gunners, he swapped the Cooks and Bakers graduating class for the Aerial Gunners class. The C&B guys were better shots than the AG guys. Bad training protocols.

I believe it was in the Korean war when they were improving fighters by reinforcing the areas were the returning planes were shot up. Someone had the bright idea that it would be a better idea to strengthen the places that weren't damaged. After all, the ones that were shot up were the survivors.

Is there some reason you can't use the high level DAQmx kit for linux?
