Using USB 6341 device for frequency generation but level is droped when conect

i am using USB-6341 Daq Device for frequency generation. The desired frequency is generated correctly but when i connect to other device the voltage level i means the Peak to Peak voltage of the frequency dropped to 0.6, 1 Volt and also the frequency fluctuated. As I disconnect it from the load or the device the frequency becomes constant and peak to peak voltage becomes 5.
Please some help me to resolve my problem.
Thanks
Best Regards

Solved!

Hi Nasib,
I just wanted to clarify a few more things. Can you answer the following questions?
What frequency are you trying to generate?
When there is no load connected do you see the desired frequency?
When the load is connected, does the frequency always change to the same value or does it fluctuate within a certain range? If it fluctuates, what is the range?
Also, what microcontroller are you using?
Can you provide any images?

If the thief enabled activation lock on the device, then there is nothing that can be done. Only the password for the Apple ID that it is locked with can disable activation lock.

I have Video camera movies that are HD format.. I am doing editing work on them using Final Cut Pro, but using DV PAL format for the projects I am editing. When I then tried to copy my work done in FCP Project that's originally DV PAL , into a new FCP Pro

I have Video camera movies that are HD format.. I am doing editing work on them using Final Cut Pro, but using DV PAL format for the projects I am editing. When I then tried to copy my work done in FCP Project that's originally DV PAL , into a new FCP Project that is HD, and tried reconnect media with original HD movies (video), the sequence project got distorted for all the text, shapes used and all.. everything changed its orientation and scale.. Is there a way by which I can preserve my work done on DV PAL and switch it preserving its proportions, scale and orientation, but on a HD project sequence?? Appreciate your help and advice..

Yes. A couple of ways that might work.
First Way
What you need to do is load one of your hd clips in the viewer and edit into a new HD sequence. Does it display correctionly?
OK, select the clip in the hd timeline and copy (command-c). Now go to the HD sequence with the material that's distorted. Select all (command-a) and paste attributes (option-v) and choose basic motion and distort. That should maek things work. What won't work is anything that you've adjusted as far as basic motion or distort in your PAL sequence. That I'm pretty sure you'll have to redo.
Second Way.
Choose your original PAL sequence and do a Media Manage changing the sequence preset to the appropriate HD paramenters with the media offline. You then should be able to reconnect these clips with your original HD media.

I am trying to shift my backup folder for many weeks to another location/drive on my pc hard drive(windows xp). have tried to use the recommended JUNCTION for the same but do not have a complete step by step instruction to do that. can anybody help me

You can redirect <Profile>\<AppData>\Apple Computer\MobileSync\Backup to a folder on another drive using NTFSLink (shell ext., might only work on XP) or Junction (cmd line tool).
In essence you move the existing folder to a new location, create an empty folder where the old one used to be, then get the operating system/tool to link the two togther and silently redirect any file operation on the old location through to the new one.

HT204053 My sister has an iPod and I recently used my iCloud account for her iPod but I see her things and she see's mine, how do I change this

My sister has an iPod touch and I recently used my iCloud account for her iPod, but I see her things on my iPad 3rd gen and she sees my stuff on her iPod, how do I change this?

Welcome to the Apple Support Communities
That's because you are using the same Apple ID. In this case, the easiest way is that your sister creates her Apple ID, and log in iCloud with her Apple ID, so you won't see his thing and she won't see your things

set the wake-on lan on the main computer
The laptop's too far away from the router to be connected by ethernet. It's all wifi.
No separate server app on the laptop, it's all samba
The files are on a windows laptop and a hard drive hooked up to the windows laptop. The windows share server is pants, so I'd need some sort of third party server running. Maybe you weren't suggesting to use Samba to connect to the windows share though?
I'm glad that you've all understood my ramblings and taken and interest, thanks The way I see it, I can't be the only netbook user these days looking for this kind of convenience, and I certainly won't be once chrome and moblin hit the market.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I tried updating iphone 6 to 8.1.3 But the phone went dead. I have tried using restore options - both update and erase, but the process stops when it tries to update Iphone firmware.

Put your phone in DFU mode,
Hold the Power Button (3 secs)
Continue holding the power button and also hold the home button (15 secs)
Release the power button while continuing to hold the home button (10 secs)
Your device should prompt with the "Connect to iTunes Screen"
Restore.

Using the same Apple id and Password you should be able to download purchased apps without being charged again.

Problems with creating a USB boot device for Windows 8.1

My iMac (late 2012) running OSX Mavericks is encountering problems creating a Windows 8.1 install disk via a USB thumbdrive. The drive has 8gb of space available, which is enough to fit windows. But when I choose my ISO image and select the drive I recieve an error message. The error is 'Bootcamp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation.
I'm certain this ISO definately contains 64-bit, so I'm slightly confused.
I've followed instructions found in other discussions talking about adding an extra line of information to 'info.plist' found inside the Package Contents for bootcamp, but that has also not worked. If I try that, Bootcamp crashes upon being clicked every time.
Any help is appreciated

First up: a question. How did you fix the crashing Bootcamp Utility? It would help out this guy: https://discussions.apple.com/message/23523783?ac_cid=tw123456#23523783
Next up: A possible solution (also posted here:https://discussions.apple.com/message/23523783?ac_cid=tw123456#23523783)
=====================
It's possible you have a Windows ISO for both 32- and 64-bit. In this case it's probably detecting the presence of the 32-bit installer and forgets to look for another 64-bit version.
A way to work around this is to not use the Bootcamp Assistant utility by following the listed steps:
The way installing Windows should work either way using the Legacy BIOS mode:
- Get a Windows ISO or DVD and copy the contents over to a freshly fat32 formatted USB stick of at least 4GB.
- Download the Apple Bootcamp Support Software (4.x or 5.x, 5.x only supports 64-bit, get that if you are going 64-bit);
- Copy the content of the Support Software folder over the the same USB stick from the first step. It should fit just right (it did on my 4GB stick with 2MB te spare!);
- Use disk utility to partition your disk. Make sure the partition for Windows is Fat32 and at least 30GB;
- Reboot your machine while holding Option/Alt at the chime;
- You should be able to select either your OSX HDD or your USB stick labeled "Windows" -> Select Windows and press enter or click the arrow;
- The Windows installer should now load, format the previously made Windows partition to NTFS;
- Continue on your way.
Can you try what I typed above? If it doesn't work, can you let me know at what step things go differently than described?
Edit: This is based on the logical conclusion that any Mac that was shipped without ODD should be able to boot from USB.
Edit2:
One other note is that Mac's have trouble booting from USB when multiple USB storage devices are attached. So make sure you connect only one storage device.
=====================
Best of luck to you!

Mixed message lengths on CAN Bus using USB-8473 Device

I am attempting to use the Frame API functions for LabVIEW
and send both 11-bit and 29-bit headers over a bus that uses both address lengths. I am currently successfully sending 11-bit
packets but the 29-bit packets are having their addressing truncated to the 11-bit
length when put on the bus.
As far as I can see I should have to set the standard
comparator to 0xCFFFFFFFF and then send messages. I am using a NI USB-8473 CAN Device for doing
this. Is there anything else I need to
change for extended addressing?

You need to OR your Extended ID with the 0x20000000 before giving it to the NCwriteNet.vi.
This is the way that the underlying CAN driver and hardware know that is it an extended ID you are trying to send.
The ID on the CAN bus will NOT have the ORed ID but only your ID. The driver/hardware filter the 0x20000000 from the ID.
This is the same for reading an extended ID on the CAN bus.
Before using the ArbitrationId, you need to AND the ArbitrationId with 0x1FFFFFFF to filter the extended flag out.

Use Preview on Device for Android on Mac - how to make it working?

We are using preview on iPad through USB connection on daily basis, but now we need to preview on Android as well.
I've tried setup on following page, but it's not working for me - i have USB Debuging enabled (it's nicely hidden on Jelly Bean 4.2.2 on our Nexus 7), but i can't see device in Folio Builder panel in preview menu (yes, i have Adobe Content viewer as front app)
http://help.adobe.com/en_US/digitalpubsuite/using/WS9293e1fb3b977c5c7b1f65ad12f28224932-7f f6.html
any idea, experience?
Thanks
Martin

Neil Enns - Adobe - We have followed these steps exactly.
USB Debugging is enabled... but the device NEVER appears in the dropdown...
We are using the native viewer app, exactly as you have described, and we still cannot get the preview on device to work?? IS there some other process we can use because the instructions in the link you just provided are not working at all.
See my comment above:
"Tried everything suggested in this thread but with no luck.
The mac we are building on is running OSX 10.9.3 and InDesign CC (up to date)
Android tablet is a samsung note, running Android 4.4.2 (developer mode / USB debugging enabled)"
