How to generate BPSK and QPSK signals with Labview and ARBS?

Has anyone used Labview to program a Wavetek 75 or equiv Arbitrary Waveform Generator to produce BPSK and/or QPSK signals.

You can use Modulation Toolkit 2.0 for LabVIEW to generate PSK signals (including BPSK and QPSK) using common PSK configuration parameters.

You can use resampling tools present in Modulation Toolkit if you need to resample the generated data to a different sample rate for your third party AWG.
In addition, Modulation Toolkit integrates seamlessly with NI's high-speed signal sources, including the NI 5421 for PXI:

Questions on Saving and mining data with Labview and DIAdem

Hi,
I am sampling two signals at 200k sampling rate. I am trying to save the data on harddisk and analyzing the data using DIAdem.
If I save the data using mesurement file format .tdm and .lvm, the file size will be about 4 Gigabytes for only 10 mins' acquisition. It is very slow to process it.
I used the software Clampex and pCLAMP(Axon Instruments) before. At the same 200k sampling rate and also acquiring two signals, these programs save the data as .atf format and the size is only 400 MB for 10 mins' acquisition.
I wonder if there is also a good way to handle this situation using Labview and DIAdem, and how to do it?

Hi, Jonathan:
I tried the TDM binary file format. The file size is 800 MB per min acquisition and it will take a long time to just open these files. For my application, I have to take data for several hours. I am looking for a way to reduce the size of files.
Is there any other type of file format that can reduce the size significantly and can be handled easily?

Face and Eye Tracking with LabView and Vision

Hey all,
For my senior project I am trying to perform face tracking and eye tracking by using LabView and the Vision Development Module. Unfortunately I am new to LV and I'm drowning in a sea of links and tutorials so I was wondering if anyone here that has had experience performing similar tasks would be willing to help and point me in the right direction or provide examples. I bought two Logitech c525 webcams and hooked them up to my pc running LabView and Vision 2011. I was able to see images captured but that's as far as I've gotten with the tools. Any tips?
Thanks,
Alex.

have a look at http://sine.ni.com/cs/app/doc/p/id/cs-14116 and http://forums.ni.com/t5/Machine-Vision/how-to-track-face-and-allocate-lips-in-face-using-labview/td-...
This thread would also be more suited to the Machine Vision section.

How to generate a second csv file with different report columns selected?

Hi. Everybody:
How to generate a second csv file with different report columns selected?
The first csv file is easy (report attributes -> report export -> enable CSV output Yes). However, our users demand 2 csv files with different report columns selected to meet their different needs.
(The users don't want to have one csv file with all report columns included. They just want to get whatever they need directly, no extra columns)
Thank you for any help!
MZ

Hello,
I'm doing it usually. Typically example would be in the report only the column "FIRST_NAME" and "LAST_NAME" displayed whereas
in the csv exported with the UTL_FILE the complete address (street, housenumber, additions, zip, town, state ... ) is written, these things are needed e.g. the form letters.
You do not need another page, just an additional button named e.g. "export_to_csv" on your report page.
The csv export itself is handled from a plsql procedure "stored procedure" ( I like to have business logic outside of apex) which is invoked by pressing the button "export_to_csv". Of course the stored procedure can handle also parameters
An example code would be something like
PROCEDURE srn_brief_mitglieder (
     p_start_mg_nr IN NUMBER,
     p_ende_mg_nr IN NUMBER
AS
export_file          UTL_FILE.FILE_TYPE;

How to switch central frequency fastly with labview and USRP?

Hello everybody,
         Recently I was making a frequency hopping receiver with labview and USRP N210 and SBX. The transmitter works on the 2.4G band, and it changes from one central frequency to another every 65536us. As I think, if I start receiving at the correct time, and change the central frequency of the USRP every 65536us, I should be able to receive the data.
    But I find that, when usrp switch form one central frequency to a different one, it spends nearly 48ms and when it switch from one frequency to the same one, it only spends 3ms(I test the performance by modifying the niUSRP EX Rx Continuous Async Reconfig on the Fly.vi example). So if I want to follow the hopping sequency, I may can only receive 17ms data because I have to save time for switching central frequency.
     My problem is that: why usrp changes central frequency so slow, how can I make the process faster? If I want to follow the hopping sequency, can anybody give me some good advice? Thanks

There is an attribute "LO Frequency" that you can use to lock down the frequency of the local oscillator. Then, when you set the "Carrier Frequency" attribute, the difference between the carrier frequency value and the LO frequency value will be realized by frequency shift in the DSP in the FPGA. Changing this "digital" frequency shift value is much faster, since you don't have to re-tune the local oscillator.
Let's say you're sweeping from 2.44 GHz to 2.46 GHz. Set the "LO Frequency" to 2.45 GHz then Commit. Then, in your loop, program the "Carrier Frequency" attribute from 2.44 GHz to 2.46 GHz. In the loop, it will only program the digital frequency shift, which will happen much faster.
Another tip is to use the property node to program only the attributes you want to change, rather than the niUSRP Configure Signal.vi (which sets many at once).
For more details, see the "Configuration:Advanced:LO Frequency Property" in the NI-USRP Help, and look at this example:
<LabVIEW dir>\examples\instr\niUSRP\niUSRP EX Fine-Tune LO Frequency.vi

How do I download a slide show with captions and music to my IPad? It is not happening when I sync.

How do I download a slide show with captions and music to my IPad? It is not happening when I sync.

The way that you would transfer photos from iPhoto to the iPad would be to sync with iTunes. Connect the iPad to your Mac with the cable and launch iTunes. Select your iPad under the devices heading on the left. Then click on the Photos tab in the iTunes window on the right. You can select the folder from which you want to sync your photos in the drop down menu bar - so select iPhoto there. Then select the album or events that you want to sync from the windows below. After you have made your selections, click on Apply in the lower right corner of iTunes.
I am not sure how the iPad will handle a slide show in the photos app that was created on your Mac. You can create basic slide shows on the iPad using the different albums, events or faces that you have in the Photo app, but as for the captioning that you have already set up, I don't know how that will work in the app when you sync the slide show.

How to display error messages in BAPI_PO_CHANGE with PO and item ?

Hello Friends,
I am calling BAPI_PO_CHANGE to update delivery flag for 50 POs.
Each PO has 4 line items. For ex.
10001     10     5.00     material1      X
10001     20     45.00     material2      X

u2026u2026u2026u2026u2026..
u2026u2026u2026u2026u2026
Now, suppose some line items have error.
I am able to get it from BAPIu2019s    RETURN table.
But how can I display that error message with PO and line item?
NOTE : I am calling BAPI_PO_CHANGE for each PO with ITEM internal table.
Please guide me.

How do you share thousands of pictures with text and captions outside of PSE? (PSE 4)

One of my dad’s retirement passions is family genealogy and old family pictures. Several years ago I gave my family PSE 4.0 for Christmas so that we could each have backup copies of our dad’s pictures. Usually once per year, I made backup copies of everything and emailed the DVDs to my brothers and sisters. Everyone knows the basic PSE 4 functions and share our dad's enjoyment with the old family photos.
My problem is that my dad is running out of pictures to scan. He wants to “share” or “show” his photos with others so that he can “borrow” their photo albums in order to scan their photos. He plans to attend a hometown high school reunion later this fall. He hopes to "collect" photo albums from cousins and classmates. I have been struggling with this for several days without any good ideas.
The scanned pictures lack any text (added as a layer?) or captions. Creating a slideshow (on my dad’s computer is slow). Also, a slideshow doesn’t let others select individual pictures to save from the slide show
He has old pictures pre-PSE 4 that allowed him to add captions directly to the picture when it was scanned. I never liked this approach as it "destroyed" the actual picture but these old pictures are more easily shared as individual pictures.
How do you share thousands of pictures with text and captions outside of PSE? Can you save or export a composite picture with all the layers?
Thanks in advance for your help and replies.

I think it is one of the printer option screens that gives me the choice of tabbed 4x6. All of the choices specifiy HP or Other so I am pretty sure it is printer software that offers me this choice.
Make sure your image has a 4x6 aspect ratio. I have been quite happy with the tabbed 4x6. Just need to remember to load the paper with the tab last.
So, in elements you set to 4x6, in printer options you should be able to choose 4x6 tabbed paper.

How to make the mobile application work with firewall and anti-virus ON

Hi,
I keep on receiving internal processing error when i try to login sap mobile solution 1.3.0 on my ipad and i was provided a solution, that is to turn off my firewall and antivirus. I works by turn off both of it but i cant possible turn of the firewall and antivirus on the server.
Can anyone guide me how to make the mobile application work with firewall and anti-virus ON
Thank you

Dear Rajesh,
Create a policy in your fire wall to allow the port to send and receive data.
I believe the port for the mobile should be port 8080 and 8443.
And your license server port 30000 and 30001

Hi,
Tou can use Table inside table to show the details this way but I'm not sure about Expand/Collapse.
Expand/Collapse are part of HGRID.
I think we can develop this functionality with little manipulation.

How can i work simultaniously with labVIEW and Excel ?

Hello . I study engineering and need some help with labVIEW, and the connection to microsoft excel.

Hi
NI offers an "Report generation toolkit". You get some VI's with this toolkit and so you can directly create your reports from LV.
Another possibility is the communication through ActiveX. There is a nice link with application notes and LV examples for that:
