I can not read Analog input (a square wave)

I am programming with Labview 7.1 on FPGA. The hardware is PCI7831. With CB-68LP connector, I connect analog input (a square wave generator) to AI0+(68) and AIGND0(67). I try to read it with waveform chart. But I can't get a square wave on the screen. I did check the square wave generator's output. It is correct. The connector CB-68LP connected with PCI7831 on analog port.
I am runing the program on emulation, not on real FPGA.
Thanks

Signal generator I used is 3010 function generator for BK precision. It is an old instrument. I probed output signal from this generator on oscilloscope with signal generator output conected to oscilloscope probe (+) and signal generator ground to probe (groud). It is a square wave.
I suspect the teminal I used for I/O port to PCI7831. Because my coworkers installed the hardware for me, he is absent recently. The terminal is CB-68LP from NI with numbers ( 1 to 68) to specify each connector on it. And I got a SCB-68 Quick Reference Label sheet on my desk to specify numbers correspanding I/O port (for example, 68 -- AI0+). I suspect if this SCB-68 Quick Reference Label sheet matches the terminal CB-68LP?
I will talk to my coworkers next week.

Can not get analog input with SCC-SG04

I have used the wizard and wrote a simple AI input channel loop with a digital readout. The voltage doesn't change.

Well, I guess I'm not sure what all you have tried or how you have things set or configured. I would first try verifying the input through the test panels in MAX. Make sure you have your DAQ card set to NRSE mode, make sure you have your SC termination equipment set as the "Accessory" to the DAQ card under it's properties, double check your connections, then see if you can read the voltage through the MAX test panels. After you can read the voltage there, then you can try using a program. I hope this helps!

Can I input a square wave using 6534 DIO card?

Can I input a square wave using 6534 DIO card?
I'm trying to read in a square wave using the
6534 DIO card. It seems like a easy enough task.
But I not having any luck yet. Any helpful hint
from experienced user? I'm using an HP square wave
generator.
Thank you,
Van

what you need is the example for digital input.
at high enough speed and enough samples to see the voltage swing.
the output of the waveformgen should be between 0 and 0.4 volt to see a zero and above 1.8 volt to see a 1.
normally on a scope you see plus and minus but here you have ttl like inputs.

Reading analog input

Good day all,
I'm using NI-7350, LAbview 8.5 and trying to measure voltage from a power source.
Is there any VIs that read analog inputs. I can't seem to open the examples.
Thanks
Solved!
Go to Solution.

Have you looked at the DAQmx? Create a virtual channel, start the task and read the value.

Can not select external input for sound

can not select external input for sound

Hey there RoosterMonkey,
It sounds like you have Soundtrack Pro installed but you cannot select your external audio device as an input. I recommend the troubleshooting steps from the article named:
Soundtrack Pro 3: Troubleshooting Basics
http://support.apple.com/kb/ht3659
Update to the latest software versions
From the Apple () menu, choose Software Update and make sure that you have the most recent updates for your versions of Soundtrack Pro 3, QuickTime, Compressor, Pro Application Support, and other important system files. Installing the latest updates ensures that your software has the latest improvements and enhancements.
Note: Be sure the application is in the Applications folder and is named Soundtrack Pro before running Software Update.
Check compatibility and driver versions for third-party devices
If you're using a third-party sound card, MIDI interface, storage system, control surface, or plug-in, check the support area on the manufacturer's website to be sure that you're using the latest version of the relevant driver or other software for your product. For information on troubleshooting possible issues with Audio Unit plug-ins, go to Soundtrack Pro 3: Troubleshooting Audio Unit plug-in issues.
Try a different Multitrack Project or Audio File Project
Sometimes project files can become damaged, causing unexpected behavior in Soundtrack Pro. To create a fresh project, choose File, then New and select Multitrack Project or Audio File. Test to see if the issue is resolved in the new project.
Delete the User Preferences
You can resolve many issues by restoring Soundtrack Pro to its original settings. This will not impact your project files. To reset your Soundtrack Pro user preference settings to their original state:
Quit Soundtrack Pro if it is open.
In the Finder, choose Go > Go to Folder from the menu bar.
Type ~/Library/Preferences in the "Go to the folder" field.
Remove the "com.apple.soundtrackpro.plist" file from the Preferences folder.
In the Finder, choose Go > Go to Folder from the menu.
Type ~/Library/Application Support/Soundtrack Pro in the "Go to the folder" field.
Remove the "EffectsCache.plist" file from the Soundtrack Pro folder.
In the Finder, choose Go > Go to Folder from the menu.
Type ~/Library/Application Support/Soundtrack Pro/Layouts in the "Go to folder" field.
Remove the "Soundtrack Pro.saved.moduleLayout" file from the Layouts folder.
In the Finder, choose Go > Go to Folder from the menu.
Type ~/Library/Caches in the "Go to folder" field.
Remove the "com.apple.audiounits.cache" from the Caches folder.
Remove receipts and reinstall Soundtrack Pro 3 and Compressor
Another approach you might consider is reinstalling Soundtrack Pro and Compressor. To do this effectively, you need to remove the applications and their receipts, then install Soundtrack Pro and use Software Update to install additional updates. Compressor gets installed automatically when you install Soundtrack Pro. You don't have to remove everything that was installed with Soundtrack Pro, so follow the steps below to completely reinstall a fresh copy of Soundtrack Pro. Note: Make sure that you have your installation discs handy before beginning.
In Mac OS X v10.6 Snow Leopard or OS X Lion
Open the Terminal application and enter the following commands one at a time and an administrator password when prompted. Note: The commands are case sensitive.
sudo pkgutil --forget com.apple.pkg.Compressor
sudo pkgutil --forget com.apple.pkg.Qmaster
sudo pkgutil --forget com.apple.pkg.VideoOutSupport
sudo pkgutil --forget com.apple.pkg.PSTSharedA
sudo pkgutil --forget com.apple.pkg.AppleHDVCodec
sudo pkgutil --forget com.apple.pkg.AppleIntermediateCodec
sudo pkgutil --forget com.apple.pkg.DSPPublishing
sudo pkgutil --forget com.apple.pkg.SoundtrackPro
sudo pkgutil --forget com.apple.pkg.Uncompressed422
Then, reinstall Soundtrack Pro and Compressor using the following steps:
Open the Applications folder. Drag the Soundtrack Pro and Compressor applications to the Trash.
Insert your Logic Studio or Final Cut Studio installation disc and install Soundtrack Pro.
When finished installing, choose the Apple () menu, then Software Update to update your software to the latest version.
Open Soundtrack Pro to verify that the issue has been resolved.
Thank you for using Apple Support Communities.
Cheers,
Sterling

When I was talking on phone, suddenly the phone was switched off. i tried to switch it on but it gave the message....connect to itunes for set up. when I connected it to itunes...it gave the message, itunes can not read data from this iphone, restore it

when I was talking on phone, suddenly the phone was switched off.
i tried to switch it on but it gave the message....connect to itunes for set up.
when I connected it to itunes...it gave the message, itunes can not read data from this iphone, restore it to factory settings. It also said while restoring ypu will lose all media data but you can restore the contacts.
I restored the factory settings....the phone was on recovery mode...it was verified by itunes and all that..but in the end it again said that iphone has some problem and can not function right now.
after that when ever i connect it with itunes, it gives the message, it can not activate the iphone further, try again later or contact customer service.
What to do now?????? Customer service people say..it is hardware problem

If it's a hardware problem, then the phone will need to be replaced.
There is no magic that can fix a hardware problem.

I am trying to import cr2files from the camera into lightroom 5 and keep getting an error message saying Lightroom can not read the files and therefore will not import them. Has anyone had a similar problem-.thanks

I am trying to import cr2files from the camera into lightroom 5 and keep getting an error message saying Lightroom can not read the files and therefore will not import them. Has anyone had a similar problem….thanks

If you are having the same problem, i.e. a disk permission problem, open your favorite search engine and search on, "change disk permissions", and I think you'll find plenty of information on how to fix the problem. This is a Lightroom forum. Your problem is with your operating system. There is no sense in rewriting instructions that are already available if you do a simple search.

Help required please. "Itunes can not read the contents of my iphone"

Greetings all,
I know this question has been asked before and I apologize for asking again but all the solutions provided don't seam to work for me, can anyone help me please.
I am receving the message: "Itunes can not read the contents of the iPhone. Go to the summary tab In iPhone Preferences and click restore torestore this Iphone to factory settings".
Now a little about my iphone, Itunes and my laptop and what steps i havealready tried.
I have an iPhone 4 running software 5.0
My itunes version is 10.5.0.142
I know these are not the most up to date versions but I have had this issue for almost 3 months now and updating the software back then was the first step I tried. I don’t believe updating to the latest will fix this issue as updating the last two times did nothing.
Every so often after starting Itunes, The program will stop responding and will require the three finger death kill (CTRL, ALT, DELETE) to open task manager to end the task of Itunes. Once it shuts down, I restart the iTunes and it runs smoothly, apart from not reading my iPhone.
When I run a diagnostic in itunes under the help tab, I get these fail messages:
Network Connectivity test: Secure link to Itunes store fail
Device connectivity test: Under support services: Itunes helper is not running. And under ports: No iPod, iPhone or iPad found.
Device Sync test: No iPod touch, iPhone or iPad found.
*See below for full diagnostic report*
I have restored back to factory settings twice.
I have shut down and restarted both my iPhone and laptop.
I am running Windows 7 32-bit on my laptop.
I am using ZoneAlarm as my fire wall, and have been disabling it when syncing my iPhone to prevent other error messages.
The iPhone is plugged into a genuine Iphone USB cable and is plugged into a USB port not a USB hub on my laptop, I have tried plugging it into all 4 USB ports and this issue still persist. The Cable is less then 5 months old, is not frayed or damaged in any way, have also borrowed 2 other cables from friends and still the same issue.
The iPhone does not even come up in windows explorer as a digital camera.
The iPhone is NOT jailbroken
I do not live close to a so called genius bar, however I have made the journey to them on 3 separate occasions last year when I first received my iPhone for a different issue, the so called genius's could not fix the problem so they just gave me a new (refurbished) iPhone, which did not extend my warranty. I will not be taking the iPhone back to them as I believe they can not resolve many issues, this is why I am reaching out to the power of the people in the wider apple community.
I have read in other forums about ifunbox and other programs for jail broken iPhones to isolate folders “iTunesDB” and "iTunesCDB" and delete them. If this is the issue is there a way to access these files through windows explorer as my iphone is not jailbroken.
I hope I have provided enough information and someone can help me fix this issue. If I have left anything out, please let me know. I thank everyone in advance for your patience and support.
Thanks

Hi AM_Kidd.
Thanks for your reply.
I have done a complete uninstall and re install of iTunes and all related apple programs from my laptop through control panel, add remove programs and also by going through program files and deleting all tracers of any left over folders remove programs may have missed.
My apologies for forgetting to add this in my original post.
Thanks again

Can not read or write to mac hard drive error

When attempting to transfer music files from an external usb harddrive formatted in windows into Itunes, I can only successfully import a small fraction of the music, and then its stops with a error, that the Mac HD can not read or write files.

It's possible the file names have some 'funky' characters in them that the Mac doesn't like ?
What format is the external drive ?

I get this message, "can not read because it was created by a newer version" I restored twice at different dates and uninstalled all apple stuff and reinstaled it again. Still nothing Help John

That message is usually a sign that you tried to roll back to an earlier build of iTunes, but occasionally I've seen it connected to a new upgrade. This technique should fix things.
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

After I search something with the search bar everything comes up small and I can not read what Mozilla has found.

I type in anything in the google search box. When my results come up on my left they are so small I can not read them. once I click on one of them it pulls up the page and It is back to normal, but it is minimized in the search.

Reset the page zoom on pages that cause problems.

Can you think of any recent changes on your computer or in Firefox, new programs, add-ons, etc.?
Have any cats walked across your keyboard recently?
My first guess is the same as yours, which is a "zoom" issue. Holding down the Command key and pressing 0 (zero) should reset the zoom level of the current site to the standard level. Is that still too small?
Regarding content overlapping, this can occur for a few different reasons. Please check on these:
(1) "Text Only" zoom
If View menu > Zoom > Zoom Text Only has a checkmark, click it again to unselect it.
(2) Manually setting font sizes
In the Preferences dialog (either the "3-bar" menu button or the Firefox menu) > Content > "Advanced" button
If the Minimum font size is set to a number larger than 9, change it to 9 or None. A large minimum font size often will wreck the layout.
At the top, there is "Fonts for" drop-down that usually will say Latin or Other Writing Systems. You will want to make the same change for both of those, so select whichever one isn't currently displayed.
Finally, make sure the checkbox for "Allow pages to choose their own fonts" is checked and OK out of the dialog.
Any difference so far?

By default, the LAN-side IP address of your AirPort Express would be: 10.0.1.1. This would also be referred to as the Default Gateway address. Is this the value that you are providing the PS3?
