Talking about software defined test equipment, my propscope from digikey arrived today. It's a whole bunch of measurement and signal generating test equipment for hobby level work. Digikey was the only place to have stock. It runs on an 8 core 32bit processor, each core runs at 20MIPS!
I am leaving this chat now, but it remains open to you. I will check back to respond to the questions and comments you leave, and I will check back before each day's webinar starts so that I may be able to respond within the webinar itself. Thank you for all of your comments, not just the flattering ones.
All of this week's slides are posted without notes. I suggest you download all of them and ask your questions now, so I can respond to them in more detail during the webinar. This will focus my remarks to your interests and also to those of others, and make the webinar stronger.
NI has several archived webinars and printed guides on this. I will point you to them on Friday. For the specific questions, i will get you answers, and I will give you my contact information Friday.
Rruther2: Hey my background sounds identical to yours, except for the broadcast engineering and BMEWS. Did you work at Gilmore Creek tracking station? I left Alyeska Pipeline in 2005 after 20 years... We have probably run into each other
if NI joins into the chat, is there some way of keeping them from taking over the session. as Rick says, they have their own networking capability withou hi-jacking this one.
Each day's chat remains open. I suggest you respond for the day's subject, and I will respond to all of the questions, including those from earlier days.
I have sent the NI-related questions to them. I will send them links to the chat. I agree that we should not have an NI spokesperson attending. This is not an NI webinar. They have plenty of them archived on their website. If NI wants to get involved with this chat, they can.
Are there areas of test that are better served with hardware based testing equipment? I imagine as computers become more powerful every year that more can be done in software. I would also imagine that there still are areas that software based testing cannot reach. Can you think of any examples?
I am not particularly interested in any NI biased representation. There is plenty of that from their website and sales force. Was hoping this would be a more generic NON vendor specific presentation
Yes, RickGoldberg is supposedly still here for another five-ten minutes; if you read the slides ahead of time you might have questions, otherwise read through quickly -- probably better to post questions to chat for answers (maybe) tomorrow...
Multi-tasking isn't working. I'll have to check back. Later, guys... Thanks, Rick.
Rick, yes please ask Agilent and see what they have to say. I know they REALLY want to justify someone forking over $20-40K for one of their high end instruments....
Okay. Finally on the right day's lecture. Should have known when the audio was diverging so significantly from the slide deck... But since I got here a bit late, I'll have to request the slides-plus-notes and do some catchup, get ready for tomorrow.
jl, you DID miss this. If you just joined, you're hearing the archived audio ALREADY.
kach30: Please look at he different approaches I am discussing. There is no one specific solution for everyone. But there are specific applicaitons that benefit from certain approaches.
Rick, I just found a "product comparison" web page by Agilent, where they compare one of their stan alones against the NI offering. Looks like the test equipent companies are fighting back against the software based testing environment...
Rick, I have electronics background and I am an Industiral Automation engineer. Software is getting importance especially in HMI. What apporoach should I carry out. I mean my software knowledge is not as good as hardware.
@wpeters -yes TS does have a packaged deployment, but you have to purchase a deployment license. There are a few types. We choose the debug/deployment license, as it provides ability to edit at the tester. If you go with the cheaper standard deployment, you can't edit.
@SumedhaHewa: A good way is the LabVIEW student edition. SparkFun has a special deal right now. If you are not in the US, then Amazon is an option. Start with something simple and work your way up.
Concerning purpose built test equipment, just take a gander at Agilent's high end equipment for cell phone systems, Mpeg video data streams, or RF microwave equipment. Can software testing using something like NI's PXI express based modules match the complexity built into these stand alone Agilent testers?
Programmable power supplies have always been a problem for us. We need to be able to swap to a different one should it fail or recuire calibration and not all power supplies have the similar interfaces. Another problem is that some test require more than one supply so I don't want to have a top level that is the same for all supplies. I've heard that object orientation may solve this but I'm looking for examples.
@RICH: Some of us have expressed doubt on why the posted slides don't already have the detailed notes included. It will make everyone's live easier, eliminating all the e-mail to and from individual participants. Please, give us a feedback on that.
I mean systems are changing very rapidly in today's world and getting complex at the same time. What is the advantage of purpose built, if we cannot add new capabilities in those systems?
What I really liked about TestStand was its database integration. It was easier to write to our test databases with TestStand than it was with LabVIEW.
Regarding TestStand and "Ready to Run": With TestStand you can add your pre-existing test code to TestStand's test executive without too much difficulty. Your code can be C, C+ , LabVIEW, and others that I don't recall.
If anyone is having problems with the audio, I had to shut down the web page and start it up shortly after the audio stream started to get it working on my computer. Just and FYI.
The streaming audio player will appear on this web page when the show starts at 2pm eastern today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.
Hello all. I am trying something new today, using WiFi instead of 3G on my Android phone for the audio portion. However, the Digi-Key Continuing Education Center web site complains that I need to enable cookies for my login to be effective, despite the fact that cookies are actually enabled in my browser. This has happened once before, but everything worked normally despite the error message. Has anyone else run into this? Why does the site think cookies are disabled? Anybody know what it is really looking for?
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
