once again sir rick and the degikey as well as design news for this event...very much appreciated for an excellent presentation to us...i will be back by tomorrow to finished all the class for the one week allocation....

good morning to all of you and happy weekend.

very interesting but too short of all presentations and discussions since day 1 class lesson. i don't have any objection all about, but needs more valuable definitions to be embedded in the slides and that much appreciated. i am now on slide 11 onwards to end of the presentation of sir rick.

although i don't have practice in software, but a user. in fact, these are already includes in building services engineering applications...

i am now on slide 2 onwards for the presentation of sir rick...

good morning sir rick! i am now bein with the class for day 2 and already download the presentation slides of this lecture...

Never used TestStand, had reviewed a LabVIEW, but used other in house software-design test system

Have used both HP Vee and Labview and a few other minor players.

Iron

i have used Labview in a lab experiment mode and have used it in a test system for the test of precision analog circuits used in process analyzers.

Iron

thank you Rick,

Iron

Thanks Rick and Rich, an interesting session. See all tomorrow.

Iron

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!

Iron

Good afternoon all from soggy Edmonton, better late than never.

Iron

Thanks!  Excellent stuff.

 

Iron

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.

Blogger

thank you Rick, good information...look forward to tomorrow

Iron

thanks Rich, see you tomorrow

Iron

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.

Blogger

TechMan25:  Beyond my last two slides today, there are other examples.  I will find some.

Blogger

Majority rules. No invite to NI. Isn't democracy a wonderful thing?

Blogger

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.

Blogger

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

I saw the purpose built analog circuit note. Are there any other examples like that which people should be aware of?

Iron

I am not a LabView or TestStand customer or user.  It might have been more helpful if I were.  It helps to be vendor-agnostic.

Blogger

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.

Iron

TechMan25:  There are areas better served with hard-based test.  See my last 3 slides from today's talk.

Blogger

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.

Blogger

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.

Blogger

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?  

Iron

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

Iron

And to everyone else, would you like a representative from NI on hand for tomorrow? Are there still questions you'd like answers to?

Blogger

Rick, do you expect more discussion about NI tomorrow? If so, I'll ask them to have a representative join the chat.

Blogger

Looks like Test Stand is National Instruments upgrade platform from Lab View...

The chat remains open.  I will be on it for another 15 minutes and will let you know when I log off.

Blogger

Thanks Rick and Rich. You all have a great day.

Iron

OK, folks, time to swtch hat. I will e-see you all tomorrow.

Iron

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.

Platinum

hello Rick, is the chat still open?

Iron

@flaredone - thanks, apparently the chat is still open, is this true

Iron

luizcosta:  If this is not answered by Friday, ask again.

Blogger

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.

Platinum

I thought I almost missed this

Iron

Russ:  I will get back to your about Python.

Blogger

@RICK: Do any of these testing tools apply to linear systems identification, state estimation, and Kalman Filtering.

Iron

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.

Blogger

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...

The firmware I work with has a light sensor so I have to test everything twice

once under lighted conditions once under low light conditions

So use the software -based test and run it twice

once for 32bit once for 64 bit

For one thing they are installed differently and most likely the underlying code is different

I have done alot of work on 64 bit software drivers they are often very different from the 32 bit drivers

 

If the OS upgrade, how about software-base test. For example, 32 bit system vs. 64 bit system.

Iron

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.

Iron

dbushnell:  I will post my contact information Friday.

Blogger

luizcost:  We will discuss hardware during the next two days.  Stay tuned.

Blogger
Thank you Rick (and Rich) for today's lecture
Iron

Rich - could you please post your email address here so I can request the detailed slides to be emailed to me.  Thanks.

Iron

Alaskaman66:  You will have to ask Agilent as well as NI.  Do you want me to ask them?  If so, I will post their answers.

Blogger

@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. 

Iron

@RICK I am a little confused on what types of harware these "software based testing" is geared to. SBC  embedded systems? FPGA? Freescale? x86? ...

Iron

Mr. E.   PXI is not the only bus for flexible test.  There will be much more discussion on buses tomorrow and Thursday.

Blogger

@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.

Iron

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?

Useful info, thank you.

Iron

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. 

Iron

Hi Rich, actually I have missed last few sessions. Great Job :) 

Iron

Lecture slides should contain details and real life examples as well

 

Iron

have nice time everybody 

Iron

For Modular software testing, there was no mention of Python (as opposed to VB).

 

Iron

I'm here for the next half hour.

Blogger

Rich - could you please confirm your email address....

 

Iron

@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.

Iron

today's lecture was realy intrsting 

Iron

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?

Iron

Rick voice is not audible

Iron

Firmware is always more flexible then changing the electronics

Higher Level Software is always more flexible than changing the Firmware or device drivers

thanks, where is that link to more info?

 

Iron
I should have said decrease development time...my error
Iron

@kach I'm the new Alex. I've taken over as of last week. Lewt me know if there's anything I can do for you

Blogger

thank you rick

 

Iron
Although flexible systems increase the software development time, but isn't this at a loos in overall performance ability?
Iron

Rich.nass@cbm.com ???

 

Iron

Thank you for today's presentation

Iron

What if we need to add capabilities in the purpose built equipment? It seems that these are very limited as compare to flexible software.

Iron

Got the slides via download.

Where is Alex? I joined session late.

Iron

Thanks Rick and Rich...Great presentations..

 

Iron

Audio is very distant for the speaker. I can barely him but i hear you just fine. Thx!

Iron

Flexible software are more attractive as compared to Purpose built equipment. Great presentation Rick. 

Iron

Can you recomand, how to  get start LABVIEW testing, initial how to get started sin a simple way ?

 

we will make sure Rick gets to all of these questions. and they are great questions.

Blogger

can you create a stand alone compiled program from TestStand?

Iron

I mean examples of real life systems or from his own personal experiences

Iron

@kanjam, are you asking Rick to provide examples?

Blogger

@rickgoldberg: Concerning slide 10, is flexible test not mainly limited by the PXI bus when setting up a specific stimulus and/or measurement?

Iron

Usually it is very helpful to visualizes things with real life examples. I am sure listeners will agree with me

 

Iron

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.

Iron

using LabVIEW, but not teststand.

Iron

On slide 10 can you explain "Handle new applications". I will appreciate of you also quote an examples 

 

Iron

I ve never use teststand 

Iron

We use LabView for some of our testing

Iron

Use LabVIEW but not testStand

Iron

Haven't used TestStand yet, However, it was recommended to me by the NI Sales Force.

Iron

Rich,

I have used it on occasion over the years.  It has a GUI that is good for visual based peolple.

Iron

Familure, with Test Stand but haven't used it as we have our own homegrown method.  I use Labview.

Iron

Used LabView, but not Teststand

Iron

I have never used any of these, hobbled by on one application with Excel.

Iron

Used Automated Test Stands some years ago.  Primarily for Integrated Circuit testing.

Iron

Used LabVIEW and Test Stand

Iron

So. Cal. Trade show demo user & some college exposure.

Iron

Yup, Used it over the decades it's been available.

Iron

Never used NI tools

Iron
I have not used these tools before
Iron

I have never used the National Inst test stand

I haven't used any of them

Iron

Never used TestStand, but used LabVIEW and other software-designed test systems.

Iron

This is the first time I have heard about Teststand, but it is good to know that it is flexible to use it

 

Iron

I've used TestStand.

Iron

TestStand user here.

Iron

Used Labview. Haven't had a chance to write much for it, though.

Never used it

 

Iron

No projects completed using National Instruments.

Iron

@richnass: I have used LabView and LabWindows/CVI but not TestStand itself.

Iron

As I just said, how many people are familair with the NI tool Rick is describing?

Blogger

Never used this tool before.

Iron

I have not used the tool before

I have not used it before.

Iron

I haven't used these tools.

Iron

for ''ready to use softwares'' ,can we give the example of adope photoshop software

Iron

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.

Iron

Hi Rich, Rick, and all.

Iron
not to mention Mac OS, or Linus/Android
Iron

Various versions of OS (XP, Vista, 7, 8, etc) could also be an issue

Iron

Love that they have made yesterday's available already for ondemand

@caa028 - Thanks. I had issues with the audio at first. I missed that part

Iron

Rick,

Have you heard of PyVISA?

Iron

@wen_tyco - just to keep you focused... ;)

Iron

the volume is a bit too low

Iron

@MazianLab - you have to e-mail Rich (he mentioned that at the beginning of the lecture)

Iron

So the slide pack available here is not complete? Where can I get the complete version then?

Iron

hello from San Antonio

Iron

@Rich/Rick, any particular reason for not posting the "complete" slidepacks on the lecture pages? (could save you time on e-mailing it individually)

Iron

Packistan, probably +05:00 GMT

Iron

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.

Iron

Hi Rick, Do you have any recommanded books or materials or links on the subject..Thanks.

Iron

Hello a bit late

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.

Iron

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?

Iron

Good morning.  Guess I'm a little early.
