I'm trying to do a FFT using I and Q Data, I need help.

I’m collecting data on an Agilent 89600 VSA, and storing it
to a file, it stores the data in I and Q format (real and imaginary) in 2 columns. Can read the data then using “Re/Im to
complex” (math function) I go to the “FFT.vi”.
After that is done how do I get it scaled and display it on a graph? Everything I have tried has not worked. If anyone can help please do.
LabVIEW 7.1, Windows XP
Thank you
Bob

Hi, Bob.
This KnowledgeBase discusses how to display complex numbers in a graph. Let me know if this doesn't answer your question.
Have a nice afternoon!

Trying to create a dvd with video and slides...need help

I am trying to make a dvd that includes video from my sister's wedding but I would also like it to include slideshows that I have already created in iDVD. Her wedding video was taken in to a shop and put onto a DVD. I would like to take the video from that DVD and combine it with my slideshows so that everything is on one disc. Plus, the menus (or lack thereof) from the DVD the shop made are HORRIBLE. Can someone tell me how to do this?
Also, if you could explain how to insert chapters into the video once I have it into iDVD that would be appreciated. They did not include these on the DVD from the shop so it's one long movie with no way of skipping ahead short of fast forwarding.
Thank you very much for any input.
Michael

Hi, Michael,
I did for my daughter's wedding what you are trying to do for your sister's. You can do it this simple way:
I took her wedding DVD and copied some of it onto DV tape and imported that into iMovie where I edited it down to some clips I wanted to go with the still photos I already had.
To copy the DVD footage, I just put the disk into our DVD player, connected my camcorder and recorded it. Yes, there was a slight loss of quality, but not very detectable in the final product. After all, I am not a professional wedding videographer and some of the stills were from inexpensive snapshot cameras.
The final video still turned out well.
I actually did another longer one, this time using the original DV footage from the wedding videographer--he let us have it because he took so long to make the DVD! The DVD I made from that is of course better quality, but not that much better that I would go to more trouble to get it.

I tried to implement photo albums using iweb and got a publishing error.

I tried to implement photo albums using iweb and got a publishing error. All was fine with my site until I added the photo album page. The software doesnt say what the error is exactly, only that it is a publishing error to my ftp
Exact message "There was an error communicating with the FTP server. Try again later, or check with your service provider."
If I reduce the albums inside to 1 then it seems to work but that takes away from the usefullness of multiple albums.
my iWeb version is 3.0.4 (601)

Publish your site to a folder on your hard drive to see if the publication will proceed successfully and open the site locally with your browser to confirm all of the alums are there and work. If they do try the following:
delete the iWeb preference files, com.apple.iWeb.plist and com.apple.iWeb.plist.lockfile, that resides in your Home() /Library/Preferences folder.
go to your Home()/Library/Caches/com.apple.iWeb folder and delete its contents.
Click to view full size
launch iWeb and try again.
If you're still not able to publish from iWeb to your server download and use the free Cyberduck to upload your website files to the server. Users have found that CD has been successful when iWeb had problems.

You are on Windows 2000, you do not have a "Firefox" button, and should consider yourself to be fortunate in that you still have menus and don't have to do anything to get the menus back instead of the "Firefox" button. (The same applies to Windows XP users).
Use the "File" menu to get to Import. You are not on Windows 7 or Vista, and don't have to put up with the nonsense added for Aero.
If you want the "Firefox" button you can get it with View -> toolbars -> (uncheck) Menu Bar. The menu bar and the "Firefox" button were supposed to be mutually exclusive (which is impossible in some cases without being incompatible).
Once you are using the "Firefox" button ...
Use the "Alt" key to view the menu bar (temporarily) containing File, Edit, View, History, Bookmarks, Tools, and Help. On Windows 7 and Vista, the menu bar was hidden by default in Firefox 4 and above. These menu items are more or less available under the "Firefox" button which has the most used of the built-in Firefox menu items available in a different format.
To get back to having menus again. "Firefox" button -> Options (second column) -> (check) Menu Bar
You can make '''Firefox 7.0.1''' look like Firefox 3.6.*, see numbered '''items 1-10''' in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 thru 8.0, look like 3.6)]. ''Whether or not you make changes, you should be aware of what has changed and what you have to do to use changed or missing features.''

Installed PE12 in June, but haven't used it since. Tried to open using shortcut and program, but nothing happens, help?
Should I uninstall and reinstall, and if so does that cause additional problems?

I'm having the same problem. I used it one day and everything was fine...next day, nothing will open. Tried uninstalling and re-installing numerous times but no change. Tried to contact support and they don't support this product (I just purchased it in August). Am VERY disheartened with their customer support.

I am trying to do the same thing. I have got the get_data function working to create the desired output. However when I replace the xml <data> block with &P65_DATA, it does not work. If I display P65_DATA on the page, it has correct output. If I cut and paste the output into custom XML, it works fine. Anyone have come across this issue..any ideas how to fix it?

Hi,
usually when you upgrade, it should not delete your files, but if it happens, than you should have a backup.
Unfortunately it is very common, that people don't know, what exactly is in the backup.
The question is, what files exactly you are missing? Own pictures, or taken with the device? Purchased music form the iTunes Store, or own? ....
Documents and files are mostly up to the developer of the app, if they are part of the backup, usually not and you need to transfer them before.
In the backup you will find just pictures from the Camera Rolle folder, everything else you should have on the PC, if you had it on the device.
Same then for music, you can transfer purchased music from the device, but your own works just one direction, from PC to device, from device to PC it doesn't work.
In future I recomand you to be sure how the backup works or use a 3rd party app (iExplorer) where you have a little bit more "freedome" than with iTunes.
Or you maybe just restored from the worng backup

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I recently updated my iPad and when I went back to read a book that I had purchased now I'm getting an error message where whole chapters are missing. I tried re-syncing with my mac book and no luck. Any help to restore my book?

I recently updated my iPad and when I went back to read a book that I had purchased I'm getting error messages and whole chapters are missing. I tried re-syncing with my mac book and nothing changed. Any help to restore my book completely?

Try a system reset. It's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If that doesn't work, you'll need to do a time-consuming "Restore."
