great sir rick...appreciated!

too short sir rick...but, great lesson for that day 1. anyway, that is the first day class presentation and much appreciated to learn more...

thanks and great....

i am now on slide 10 of the presentation....too short!

just downloaded the presentaion slides for this day 1 class lesson

good morning sir rick...i am going to start your day 1 lesson before going to bed...

Thank you for archiving this class.

 

Iron

A session seems overclocked (too fast). 

Hello from Oregon to archive learning

Ricks script would be useful with the PPT as a directory.  Is it available?

Iron

I use the Embarcadero C+ and Delphi development suite for doing software instrumentation and data collection.

Iron

Slide #9: "Instrument Being Tested" means you're testing an instrument?

Iron
catching up on archived presentation as I missed this one
Iron

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...

 

Platinum

Catching up missed 1st presentation.

I am now on the chat for at least the next half hour.

Blogger

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 ...

Iron

Thanks rick. looking forward to for tomorrow's session... 

Iron

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).

Blogger

If any of you have answers, more information or contacts for the questions, please post them.

Blogger

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.

Blogger

Thanks for the session, rick.. Very interesting.. Really s/w based testing is very useful nowadays... saves lot of time and effort.. 

Iron

Thanks Rick, very informative

Iron

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.. 

Iron

Reyaz:  One of the advantages of software-based test is that it can handle real-time.

Blogger

Reyaz:  Yes.  LabVIEW is an example of an ADE for software-based instrumentation.

Blogger

Is LabVIEW an example for s/w defined instrumentation??

Iron

JosephD:  See my slide #9 for advantages of the tradional approach.

Blogger

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...?

Iron

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.

Blogger
paul_b:  It is Microsoft Visual Studio.Net.  See my slide #14.
Blogger

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?

Iron

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.

Platinum

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.

Blogger

Going off to snag the rest of the week's slide decks.

 

Time to make some advanced-preparations notes.

 

Manana, everyone.

Platinum

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!!

 

Iron

TechMan25:  Everything has changed over the last 5 years.  Look at my slides about device complexity.

Blogger

GeoSei:  Proprietary hardware can have compatibility software issues.  Commodity hardware may be better.  I mentioned this.

Blogger

Greetings Rick,

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.

Iron

By "Importance" I mean in terms of developing complex platfomrs. 

Iron

Some of your questions are being answered by others in this chat.  Look for them.

Blogger

Rick,

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?

Iron

kamjam:  I covered a little on the importance of software-based instrumentation.  Please tell me how you define "importance" specifically.

Blogger

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.

Platinum

All technical questions, as well as others, that I cannot answer now will be answered later.  I appreciate your detailed knowledge of this subject.

Blogger

OK floks I will have to leave. Another meeting in 15 min. Thanks Rick and all. e-See you tomorrow!

Iron

This chat is being archived, so you can see it and I can respond to it later than this hour.

Blogger

RICK: I'm not seeing the answers to technical questions. Are you planning to provide them later?

Iron

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

 

Iron

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.

Blogger

How software intsruments play a critical role in testing, validation and verification tasks in today's working environment?

 

Iron

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.

Iron

Thanks Rick, the ground rules just aren't clear to me. I'll look at the upcoming slides.

 

Iron

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.

Iron

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.

 

Iron

I will look into getting the notes posted.

Blogger

I will say lectures slides must be elaborated for the users. This would be great!!

 

Iron

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.

Blogger

Yes, hardware is connected through an interface.

Blogger

Still not clear - are we talking about using "test software" that is interfaced to the hardware in the normal way?

 

Iron

Thanks Rick and Rich.

Iron

@RICK I would venture to say the most of us will be interested in the detailed slides. Could you post that or e-mail to all registered participants? 

Iron

thans Rich...welcome aboard to these web-b-neers. looking forward to a great week.

Iron

thanks Rick...looking forward to tomorrows session.

Iron

Rich, just sent you an e-mail... looking for a copy of "good" slides...

Iron

If the connection between the instrument is Ethernet, perhaps we could build the instrument into the equipment and remote-test it from afar ?

Iron

You can post any questions for Rick for upcoming classes ahead of tie and I'll make sure he addresses them in classes later this week.

Blogger

Rick,

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?

TIA

Iron

Will we have more about the real-time measurement?

Iron

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.

Iron

If you wish to download the remainder of this week's webinar and submit questions after you have seen the slides, please do.

Blogger

Thanks EdB_Vt - does this mean that the hardware is connected through an interface when we do the testing being discussed?

 

Iron

See you all tomorrow!

Iron

Protocols and connections between controller and instrument will be discussed later this week.

Blogger

Seems like we have several options when it comes to test -- interrupt!

Yes, thank you, Rick, email heading off to you shortly!

Platinum

Thanks Rick and Rich. No time to linger, see all tomorrow.

Iron

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.

Iron

I don't see the name of the moderator anywhere. That's why I greeted Alex, and not Rich. HI RICH!

Iron

@tHasham Thanks for the welcome. I'm looking forward to it.

Blogger

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.

Blogger

@JSP: Ethernet is now more common that GPIB/IEEE488

 

Iron

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.

Man, this session seemed to "fly" by.

Platinum

Good point to clarify - @leckerts - I assume this is discussing test during product manufacture, not automated S/W test.

Iron

I'm interested in the connection/protocol between the controller and the instrument - what is the default method ? - is it still GPIB/IEEE 488 ?

Iron

Thanks a lot Rick. It was such an informative presentation. See you tomorrow

Iron

It would be nice to have the more details of this lecture by filling in the extra verbal information into the NOTES section of the slide.

Thanks.

Iron

Reloaded the page and listenting to the beginning of the presentation (that I missed) - sorry Rich...

Iron

Thanks Rick and Rich

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..

Iron

MATLAB allows you to program in C, C+ (by importing), and MATLAB's own language. IT's very similar to Labview. Though I find it more flexible

Iron

At the moment, it IS just buffering -- because the audio portion is over already.

Hang out for some further words, though...

Platinum

@FrankBishop..If possible try to use Firefox..it is much better than IE.

Iron

So are we testing the software itself, are we modeling the hardware in software, or what?

 

Iron

We will discuss  hardware drivers in much more detail.  Stay tuned.

Blogger

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?

Iron

Welcom Rich Nass..we were wondering that Alex has different voice today..:)

Iron

My older version of internet explorer says just buffering

Upgrade your browser to hear the audio (I suggest chrome)

RICK: How do you see the Qt QML, Creator, Designed ADE?

Iron

I have also noticed the same issue with Agilent

Iron

@rick - is there an easy way to interface with PXI and PXI Express cards without writing Windows hardware drivers?

Iron

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?

Iron

So, we're hoping/assuming that Rick is going to read through and maybe respond to some Chat questions??

 

Platinum

This webinar is archived so you can find the audio and slide deck later.

Blogger

sorry, Rich Nass

Iron

As a programmer I would rather use a real language other than some sort of matlab or labview

compare using LabView/CVI versus bringing C code into Labview.

Iron

No, it's Rich Nassm not Alex

Iron

@MazianLab - thanks... I joined late today, saw Alex in the chat and assumed that he was hosting...

Iron

thank you Rick,

Iron

I seem to recall that Alex said HE was handing off to a different "moderator" at the end of that LAST session. So yeah, not "Alex" this time.

Platinum

Alex is not Alex anymore he mentioned that in the 2nd semester someone else would be taking over

Thanks DigiKey!

 

Iron

That's not Alex. Is it?

Iron

We use Visual Studio a lot, both C# and C+ .

Iron

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.

Iron

is there an easy way to interface with PXI and PXI Express cards without writing Windows hardware drivers

Iron

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.

Iron

Is it me or Alex sounds different today?

Iron

When I lost audio, just clicked the pause and then play and it resumed.

Iron

You have any comments about development programming with MATLAB? It's similar to LabVIEW to some extent

Iron

C#..yes..C Sharp

 

Iron

@paul_b No it's Microsoft Visual Studio, the languages it supports are C/C+ , VB .NET, C#, etc.

 Try to reload the page or log out and bag in.

Iron

NI always provides the driver for Visual studio.

Iron

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?

Iron

C Pound?  Perhaps you mean C sharp.

Iron

@Alex/Rick - join the comment from flared0ne... woudl be nice to have more (some???) content in the slides.

Iron

@ddewan - no problems...also works great for going back and capturing archived sessions. just have to replay the session.

Iron

Do you think Goldberg should elaborate his slides for listener understanding?

 

Iron

Do you use an environment that's ot listed on Slide 14? Which one?

Blogger

So, where do you get control and measurements driver for Visual Studio.net?

Thanks..

Iron

remember, whenever you use NI LabWindows/CVI, you are locking yourself into that specific environment. the same with most any 3rd party software

Iron

@andy - F5 to refresh.

Iron

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??

Platinum

I think it should be Microsoft VISUAL Studio.NET

Iron

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?

Iron

@jl thanks, this works great. I hate missing part of the classes due to work commitments

Iron

@Alex - missed your question today (assuming it's the same)... H/W, S/W extensive test background and currently focused on standards

Iron

@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)

Iron

Interesting responses. It appears that no one does just software or hardware anymore. It's always both.

@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

Iron

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).

Platinum

Hi all, anyone know if there is a way to save the lecture as an mp3? or if that is provided afterwards
