using 6341 USB frequency generation device but level is droped when conect

I use the DAQ USB-6341 material for frequency generation. The desired frequency is generated correctly but when I connect to any other device, the voltage level, I mean that the peak to peak of the frequency voltage has dropped to 0.6, 1 Volt and also the frequency has varied. I unplug the charge or unit frequency becomes constant and peak-to-peak voltage becomes 5.

Please some help me solve my problem.

Thank you

    My pro iPad connects to the WIFI, but loses connectivity to drops in use.  My other IOS devices (iPhone, macbook, etc.) do not have this problem.  Ideas to solve?

    Hello BrooklynWM!

    I definitely want my iPad to stay connected to the Wi - Fi connection while I use it.  Thanks for posting that other iOS and OS X devices have no problem with the connectivity dropping.  We can try a few things.

    Would first go through the steps listed in this article: If your iPhone, iPad or iPod touch connects to a Wi-Fi - Apple Support Network

    Then if it does not help, you can check network settings with this: recommended for the WiFi routers and access - points Apple supported

    After trying those, if you still see the drop connectivity, make sure the iPad Pro is updated with iOS 9.3.2 and check to see if the connection when you are in a certain place, time, or one event happening elsewhere in the House.

    Best regards.

  • GPO: CD and DVD: deny write access prevents the user to use their USB Pen drive, but other users or ok

    My users have secure readers Pen who throw a CDROM partition with a secure logon application that decrypts the key to mass storage USB the USB on successful logon. The problem I have is that users who install the USB cannot initialize then the app launcher CDROM to enter their password to access the element of the rendering it useless USB mass storage.

    However, any user who has the same type of USB key that plugs in to the endpoint that has already installed the drivers is able to access their own USB or the other users of USB stick (knowledge by providing the password).

    So I've isolated the problem being down to the presence of the GPO setting shown above on the removable storage access policy and by not having not this policy in place when a user installs the USB key, they have no problems, but I can't find a way to clean a user that is already broken, even if I delete the GPO from this user , remove their local profile so that they start as a new user (no roaming or other data) and use a variety of utilities such as USBOblivion to clear the registry and the file system of the USB and installation. When the original user logs back and then installs the USB again, they have the same problem, but no one else does. I have the same problem if I try with another user or administrator as the first user after "clean it up". Everyone can use the pen drive except the user who originally installed when the GPO was in place.

    If I move the user to a new endpoint or rebuild their end point, then they have no problem being the USB setup and then use it because the GPO has been deleted, so what I need to know, that's what he's talking about installing USB and the GPO which is tattooed somewhere in Windows and how can I remove it?
