DAQ doesn't show the input waveform in Labview as it is in oscilloscope.

Just bought a PCI-6035E DAQ board + CB-68LP connector and testing it by inputing a square/triangluar/sine wave from a wave generator. In MAX, I can see the waveform as in the oscilloscope. However, when I try to see this input in Labview by using the Waveform Chart VI, the displayed waveform becomes an arbitrary one. Why is it happening and how can I correct it? I'm a novice in this field, so your advice would be highly appreciated.

Seems that there's something missing in connecting to the daq card: in most cases this situation occurs when the signal reference is missing. When you input a signal in an oscilloscope, you wire both a signal and its reference (ground or similar), otherwise you see nothing than noise and disturbs.
With a daq card things are a little more complicated 'cause you have a more flexible and more universal instrument than an oscilloscope; you must decide which type of connection to use: referenced- or not-referenced- single ended or differential connection, which channel(s) to use... and the configurations in MAX and in labview must match if you want to simplify your job.
I suggest you to study carefully the card user manual when it describes the analog input w
iring and all the consideration about different types of connection. My experience is that in most cases the differential input is better to reduce signal noise and reject disturbs, but you must use 2 channels per signal...
You can also look at this tutorial about wiring an input signal:

You're entering a (slightly) complicated but (very) interesting world. Good job!

Thanks Barney, I tried that but all that comes up in Spotlight are the log files that show the file paths! I don't know how Steam works. Are all the files held by Steam on their server perhaps?

My weather app doesn't show the feels like temp or wind, etc. How can I fix this? I am running iOS 8.1.2.

is that really what it is? this is the native iphone weather app. the funny part is that when i use the actual weather channel app, it does provide it.
is this an api issue with the weather channel and the iphone then? i guess there's no fix?
thanks for your help by the way.

I can't open my iPod library in iTunes, the app doesn't show the device at all, no error message, nothing, but windows 8 opens it like it would a flash drive. It has worked for me before just fine and both have the most updated software versions.

You cannot update it if you can't get the latest version of iTunes. Actually, the latest version of iTunes will run in XP if you have Service Pack 2. Also, you posted in the iPad forum, and your profile shows you have an iPad, but in your post, you say it is an iPod. Is it an iPad or an iPod?

I downloaded an album from iTunes on my iPad and then i synced it with iTunes it doesn't show the individual songs in my library just the album which opens another window. Can you help?

I downloaded an album from iTunes on my iPad and then i synced it with iTunes it doesn't show the individual songs in my library just the album which opens another window. One of the albums won't even play the music. Will only open the "booklet" for the cd but not the music. Can you help?

Hello dannugget
Normally, if the songs showed that it is purchased then it is probably already in your library. If not check out the article below to walk you through downloading your past purchases. You may also want to check to see if you have Automatic Downloads turned on so that way next time you can get your tracks without having to plug in and sync.

Many people are having this problem for the last couple of days. This is a problem that Apple has to fix. If you look around the forum, you will see many, many discusssions about this and they have been going on for a few days.
According to Fly150 in another discussion, this is a workaround - for the time being.
If you want to update the Apps while waiting for Apple to fix Updates:
1. Go to App Store
2. Select Purchased
3. Select All
4. Scroll down to find the Apps showing update
5. Select update on the Apps
This should update the Apps and get rid of the update count in App Store.

You cannot buy music from itunes, as they do not sell it in your coutnry. You would have to buy elsewhere.

HT2693 How come my apple map doesn't show the map on apple standard map.. However, it does work on google map. I was trying to close the apple maps, restart, and many other ways but still didn't work. Please help me.

A standard map on my iPhone 4s is suddenly not working. It shows the blue dot but it doesn't show the actual Map where I can see the streets.
I don't know how to fix this problem. I did try so many ways even restarted iPhone but still not working... Please help me out.

Hi JinHDK,
Yes I worked previously but it's now not working. I did double click home botton and terminate the maps many time but still not working.
The standard maps just not show any route only the blue dot (my location.) I really don't know what to do. Btw, I used to live in SF but now I'm traveling to Thailand. One of my friend is using iPhone 4S as well but his maps is working. So I guess it is about its application on my phone...
Thank you.

My Nokia N95 doesn't show the codes like *#0000# and *#06# anymore. Actually all the codes , even those for restoring to the factory settings don't work anymore. Now when i type them in , the phone only bips once and that's all. They worked before , but i don't know exactly what may have caused this error. Maybe some application i installed on it or what else!? Please help. Thank you.

My smartwatch 2 doesn't show the home screen

Hi,
Just got my smartwatch 2 yesterday. I successfully paired it with my Xperia z. Now the watch doesn't show the home screen it only shows dimmed time. When I try to touch the home button it doesn't do anything, I tried updating it but still the same problem. I received a call on my mobile and I was able to manage it from the watch by cancelling or answering. Any ideas.
Solved!

IPhoto 11 doesn't show the photos that I just imported from an SD card, but says its importing to library 15 min after SD card is removed.

iPhoto 11 doesn't show the photos that I just imported from an SD card, but says its importing to library 15 min after SD card is removed. The import seemed to start normally, I went to mail to check messages, came back to iPhoto & the usual prompt about wanting to delete the photos on the card never came up. The photos didn't show up in events or the library & the device icon wasn't showing so I tried to import again. A prompt then came up saying that I needed to wait until the import was done!

Hi, this problem is also happening to me also. I just took some pics of my daughter on my nikon d3100 and imported them from SD card to iPhoto. It says 'preparing to import' but during the process i do not see the photos being imported. After it was done, there was a new event album, i clicked opend it to see my photos but all of them were blank. I forced quit and re-launched iPhoto but it didnt work, i even re-imported, not to no avail.. Please help. Earlly 2011 13' MacBook pro 10.7.2

PC Suite doesn't show the messages in memory card

Hei,
Phone - 6210 Navigator
PC Suite - 7.1
Memory in use: Memory card
When I open the Communication Centre from PC Suite, it doesn't show the messages. In the left pane, number of messages in the folders is shown as zero. This happens if the memory is set to memory card.
On the other hand, if I set the memory to Phone memory, the messages are shown properly. Why is this happening and what's the solution?
When I tried to take a backup, all data, except messages, is backed up.
Few days back, I could access all the messages via PC Suite. It worked fine. But, now, there's some problem.
I've lots of messages in the memory card & I wanna move them to different folders. How else can I do it?
-Babloo

Hello,
I think I found the cause of the problem. There's some problem with the memory card.
I set the memory for Camera also to memory card and when I take a snap, something something happens. If I set the memory to phone memory, it works fine.
But, I can access the files/folders in the memory card both from the mobile & via PC Suite.
Now, my question is "How do I retrieve the messages from the memory card?"
Any help will be greatly appreciated.
