RF testing with labVIEW

i'm a CDMA RF testing engineer and i'm asking for a labVIEW training, but my manager asks me what will LabVIEW provide you as a CDMA RF testing engineer. i'm applying the TIA/EIA/98-E standard on our CDMA wireless units plus i'm involved in automated tests, but really i want to get more information about the capabilities of labVIEW regarding the RF front end of our units.. waiting your reply ASAP please.. Best regards..

I wish I still had his business card, but one of the RF guys in National, used to work for Nokia.  Panasonic Wireless uses LabVIEW for testing and certification of their products, and I know it is used in sony ericsson.  I am not sure what your background is, so I can address specifics.  but I would call you local DSM (national sales guy), and work with him... the official party line is 10x speed increase.  in development of apps... but not realized without the learning curve. 
If you need more info you can reach me at [first initial][lastname]@[my company].com. 
I learned labview in 1993 and started in RF communications satellite payload testing for RCA/GE/MM/Lockheed.  I have worked in the wireless industry for 7 years, as well as automotive and now video.  You know youjr manager where we don't, and what he would need to gain his confidence.  there is plenty of labview support for R&S/ Agilent/wavetek/ anritsu test equipment and examples.  Again, talk with your DSM, and I am sure he can find the resources to make the case for you both within and without NI.

 Hi MAshraf,

 Paul S. had some really great information in his post. In addition to that here is what National Instruments has done in the way of RF Test systems.

 LabVIEW was used to develop these RF software packages. They could be duplicated using nothing more than LabVIEW.
  1. Modulation Toolkit 
  2. Spectral Measurements Toolkit 

LabVIEW training is where you will learn how to effectively use LabVIEW to build custom application. More information can be found at the link below.
  3. LabVIEW Training

I hope I answered your question. Please post back to this thread if you have any more questions, have a great week.

I'm not sure what more I can add to Paul's reply.

I have a similar background and it looks like we both do contract work (consulting) as System Integrators.

Been working in RF since 1997 and using Labview in that field since 1999.  Labview has been instrumental at getting projects delivered on-time to my clients' customers.  As Paul mentionned, there are many drivers available for the practically all instrument manufacturers.  If you did not purchase equipment yet, you should seriously consider the PXI chassis with RF modules.  They may actually save you money (and time).  Get your local NI rep to help as well.

If you are new to LabVIEW, you may want to consider having a LabVIEW Architect to design the system with you and to provide assistance so that you can code your test software in record time.  Also, this forum contains a wealth of info and many top notch contributors that can get your project going in no time..

Plus, there are trick you can do with LabVIEW and multi-core processors that will put other languages to shame..  While you have fun writing code..

Dear all ,
i'm really greatful for your support,
and actually the picture is starting to get obvious and clear to me.
i just want to know the right way to acheive the target which is building a testing platform for our CDMA units based on labVIEW. so i want you to advice me, what courses should i start with. RayR, u told me in order to to design the required system i should be a "LabVIEW Architect". which is passing through the Biginners I & II courses next to the intermediate I and II course finally to the Advanced course.. is that right ?

also after checking this url https://www.ni.com/en-us/shop/category/courses.html i found 3 levels of RF trainings NI provides.
so just i want your advice guys to decide which courses should i take & ur recommenditions.

thanks alot for your support , Paul, Ray and Mathew

I have another Question.
we have (in my opinion) a good testing and measurement resources in our lab whic is as follows :
1- Agilent 8960 Communication Tester
2 -  R&S  Sygnal analyzer FSQ-8 - (20Hz - 8 GHz)
3 - R&S Network Analyzer ZVCE - (20KHz - 8GHz)
4 - R&S Signal Generator SMIQ 06B - (300KHz - 6.4 GHz)

do these resources (after installing the labVIEW instrument drivers) will provide me an alternative way to perform my signal aquiring and analysis rather than the RF PXI's available by NI ?..

Best Regards
Mohammed Ashraf

as with any tool, labview will provide you an easy to learn language to automate your test, plus an extensive support network.  both NI tech support and through the forums here.  There is a learning curve involved.  By default, when you install labview from disk, there will not be any drivers for those instruments, but drivers are available to download through both the R&S website and from the NI website for these instruments.  the SMIQ can be a bit tricky, but if you know the keystrokes, as you get to a specific menu, and hit the help button, it will show you the GPIB command for that function.  In my experience, I usually start with the stock driver I download, and taylor it to my specific need. 
I think the question you are asking is there a CDMA measurement suite already completed for you in labview.  The short answer is no.  If you do not wish to design and code a suite, there are 3rd party companies that make their living doing systems integration.  As one of the previous posters answered, these can be found through the NI alliance members.  You can hire them by the hour, or for a complete system.  They can do stuff as simple as architect the software for you to coding a framework for you to completing the whole suite.  Most will give you the source code, although you need to check the contract before you sign it.  But as far as I know, you will be in the same boat no matter what language you were to choose.  One major difference is LabVIEW is specifically designed to do this type of coding so in terms of asking for help, like here in the forums, you are more likely to run into.. "been there, done that... and here is how you do it" in terms of specific implementations.  I doubt anyone, should they have already coded a system in the exact configuration as yours, will just give you the code.  But many examples and a lot of help can be garnered from here. 
I hope that I have answered your question.

LOL!!  😄   Sorry, I should have explained it a bit better,

No, it is not necessary to be an Architect in order to design your solution.  I was recommending that you work with someone who is either a Certified LabVIEW Archiotect (or has obtained the training) in order to get you going in the right direction much faster.

If you are starting with LabVIEW, I would recommend the first two courses (LabVIEW Basics I & II) as well as the RF course offered by NI.  We are trying to organize a course before the end of August in our area (Ottawa). 

The advantage of working with an Architect is to write the Test Specifications (document) which defines the what tests should be carried out, the look and feel of the Operator Interface, as well as the code structure in order to meet timing requirements, etc..  It may be well worth the investment..

The above instruments are excellent instruments.  No need for PXI instruments.  I suggested that only if you had not yet bought any instruments.

The R&S drivers and example VI's (Located inside the VI Tree) should get you started..  However, you will have to develop code for your specific tests.  Paul  offered good information in his post.
