Sheesh. Get here a little late and completely missed it ALL. Couldn't figure out why I seemed to be getting audio which was discussing stuff waay toward the bottom of the chat session. But then, I'm constantly seeing "login", even after having confirmed my login several times. Now I know.
So, now I'm listening through the archived audio. I've got the slides in another window. Have to check, see if the slides have Rick's notes enabled or not... Have to read through, see if I'm supposed to request today's slides-with-notes again. I'm tempted to put THAT off until the end of the series, but I think I get more benefit on a daily review...
Thank you Rick for sharing, and also to Design News and Digi-Key. Looking forward to the next session. I am user of both Labview and MSVC amongst many others in our test lab, and I am curious. LabView is notoriously known for its non-intuitive user-interface, almost by design. I wonder if there may be any effort to bridge this gap from Ni's point of view ...
Thank you for you questions and comments. Remember to tune in tomorrow. I am leaving this chat and will respond at a later time, but I believe it will remain open so you can post questions and comments and share information. Thank you for the questions and comments. I hope this will help begin a discussion on this subject. You can use a Design News Blog for this in the future (after this week).
Leap Motion is a company (http://live.leapmotion.com/about.html#faq) which appears to be in a different space that what you are discussing. Tell us where we can find the right one.
Thanks. I have used LabView and developed few diagnostic virtual instruments for a high speed image data transfer, but couldnt catchup with the clock speed as the buffer memory used to fillup fast and I used to miss few frames. But however, I never faced problem with respect to catching an edge for trigger. But always had in mind that s/w based instrumentation tends to lack in this Interrupt servicing area. It will be great if you list out few other developers(providers) of s/w instrumentation platforms..
Rick, If I understand correctly, if the diagnosis is done using the s/w residing in the host system but not on the instrument itself, can we say that it can be challenged with respect to the response to the realtime interrupts...?
The live portion of this will end soon, but I will still pose answers to the questions that I have not yet answered. And, of course, you can ask follow-on questions using live chat during the future portions of this webinar.
Devices have been getting more complex and integrated about every 6 months. That is pretty much a constant. More specifically, has there been any area of test that has seen great change or advancement in the last 5 years?
Oh, Rick -- perhaps a useful heads-up: if you haven't stumbled across what Leap Motion has recently released, you might want to take a look at it -- they're going to be tangled up with "Software defined instrumentation" in a big way, starting probably in just over six months or so. I have no connection with them, but I'm hoping to.
If any of you are interested and the vendors agree, I will post contact information for the vendors whose products are mentioned and those you mention. You don't have to respond to this. I will ask the vendors.
I know the subject in hand is very broad, and it is not possible to cover the entire domain. However, I am sure we all will learn from your expertise and knowledge that you are possessing on the softwar-based test instruments. Good Luck!!
Refreshed the page and was able to listen to it from the start. Has there been many significant advancements in the world of test over the last 5 years ? Maybe want to answer this question at the end of the lecture session once we have gone through the next 4 days. Have a great day.
It seems that instrumentation hardware is becoming so much more complex over time that software is having a difficult task of keeping up with it. Especially when using discrete channels for DSP vs. channel multiplexing. Going outside of the hardware manufacturers proprietary recommendations can also lead to issues when serching for test software which is compatible with it. What can we do to help prevent this?
Just saying -- we have several options, generally, when doing test. You typically have a device-under-test, which can be a chip, a module, a plug-in, a card, a sub-assembly, a major assembly, a complete system. Sometimes the DUT plugs into a test bench somehow (an exerciser which only faintly resembles the end-use environment), because of a need for more switches etc to test more options than the native environment would access. Sometimes the DUT is complicated enough that a valid test environment HAS to essentially duplicate the native (end-use) environment, in which case the "testing" tends to include presenting the widest possible range of valid external inputs to confirm receipt and handling...
Wow -- not a simple subject -- I'll be interested to see how you break this down into functional concepts to tackle it in bite-sized pieces.
Just a note: click-and-drag and CTRL-C to save what you type if you get longwinded, because the system DOES sometimes glitch-and-barf and discard your stuff. If so, click and CTRL-V to paste that "thank gods I saved a backup copy" chunk of text, and try again.
I am a Systems Engineer and work in avionics environment. I want to know the importance with your perspective as I work with these instrument on daily basis
You can save the presentation with both slides and audio and then play them back either together or separately. This enables you to have a slide deck that you can increment, not the one that I did today.
BROWSER: I have worked mostly with Safari with no problem. A couple of times with Firefox. Never an issue of versio X or Z. Just typical Internet failure that requires reload a page here and there.
Maybe this will be covered, but going thru the different means of interface control under test and some recommendations for tools would be good (ie tools for verifying Webclient and SNMP controls/status of UUT). I know labview can handle SNMP controls/status with the appropriate plugins but no tests for actual SNMP compliance. But so many hardware products require test of the webclient user interface. It seems GPIB/IEEE488 and RS232/422/485 are becoming interfaces of the past for control/status for both test equipment and Product UUT's...we are in a SNMP and Web age now.
Ok, so this is a general discussion about using Labview or custom software through Teststand, the alternative HP equipment rack, or a custom hardware setup.
You should be using IE9, not IE8. Also, if you download the slides before the presentation, you can increment them in PowerPoint without any streaming other other connectivity issues.
I've been told that Python is best to use for an open-source method of software control for instrumentation. Could you please ellaborate upon this for us?
NI has a good environment but the individual instrument drivers are usually written by the manufacturers. Some of the ones that are on the NI web are good and some are not good. If you get not good ones, you may need to develop your own drivers.
I have used IE 8 for all the first 100 weeks sessions with little to no gliches. The ones I did encounter were temporary. One thing I did notice, if you navigate off this web page, the audio will go away and you will have to reconnect to get back on. The same with most/all streamers.
Its seems the main problem is within the system environment from which you are running. that is, fire walls and coorporate tracking software sometimes do not treat this in a friendly manner. that is, locks it out.
If you want a copy of the slide deck that includes notes that I used today, please send an Email Requst to Rich Nass Rich.Nass@UBM.com with today's date and request notes in the subject line.
Personally, I think I'm going to go through each day's session and download the slide decks now -- get a jump on what is coming up. Each day's session is automatically archived, TechMan25, but yeah, you should be able to listen to the archive already.
Only caught the very end of it. Was having difficulty getting the audio going. Please archive it before part II so I can run through the archive of the session today before Part II. Thanks..
What are the drawbacks from a SW defiined approach? I heard use the traditional approach if you want to take a quick measurement. I believe Rick means setup time not necessarily test time. What are some reasons to not go with SW defined?
Some equipment, such as those with Agilent (previously HP) do not have any delepoment programming environment. So you basically have to code with ancient languages such as Fortran, or BASIC in order to control them. How would you say we deal with such programs?
Have refreshed/logged in several times ... get the introductory audio message, but no streaming content; just "buffering" ... may be the NASA firewall (logged in via the NASA network). Will try to catch the recorded version post-event. Thanks for the recommendations.
Software defined test equipment is alot like the older military ATE with general purpose analog and digital i/o. the actual instrument was defined by how the h/w was configured.
What about recommendations for software packages/tools for testing Webclient/browser and SNMP based interacts with equipment. Example say a product that can be controled and/or monitored by a webbrowser and/or SNMP?
Just an observation -- I'm hearing a LOT of valuable stuff in the AUDIO, in re slides four through eight (which themselves are all exactly alike, just indicating what the audio contains for that interval). After listening for awhile, it is fairly obvious that Rick has a written "content" for this presentation (because he is covering waaaay more than the slides show) -- would it be remotely possible to get a copy/copies of that written information?? Because he HAS good content, but I haven't been able to keep up, typing notes... Please??
I would love to be part of this live session, but my DesignNews Radio audio is continuously buffering, and I cannot hear ... Anyone else experiencing this issue?
@ddewan - yes, if you hover your cursor over the "radio" streamer above, you should see a Real Player popup when clicked will pop up a capture window(s)
@ddewan - the newer version(s) of the Real Play add-in does a very nice job of capturing the audio. may have to wait until the seesion has been archived
Hey, guys -- and Hi, Rick. Coming to you from hotter-and-hotter Central Florida.
Hardware engineering: projects, prototypes, and products. Enough software to make the hardwarewalk, talk, fly, etc -- increasingly, being able to field a useful test suite behind a GUI is a highly visible "value-added" bit to leverage my functionality.
Some Labview, some Matlab, etc... HUGELY interested in underlying matrices useable for quickly assembling virtual knobs, buttons, switches, slides, etc. (SERIOUSLY intending to jump in with the Leap Motion SDK -- which, by the way, WILL become generally available as soon as the first devices start coming out in December).
