HP 54120 has

I'm hooked up to an HP 54120 A and I can't seem to connect to it. I have sent simple queries based on the VISA and they all get expired.  Max sees GPIB0::7 and I can choose it as a device ID in LabVIEW. But I can't seem to listen or talk to me. Someone I talked on the phone suggested that I switch the TALK/LISTEN mode on the front panel. All I see is a LOCAL touch and nothing happens when I press it. I have a program that I wrote a year ago and it worked at the time. But someone was playing with the buttons on the scope at the time and there is here no more.

Use the menu on the Panel before select HPIB > Mode = covered ('someone' probably thought that setting don't mind if she went) or wanted to print on an old plotter

    Hi all

    I have a strange behavior with the dock in macOS Sierra, especially with the "System Preferences" icon After you open the system preferences application, the icon was his suddenly replaced by another icon (see image below). It looks like a Doc App icon?

    Is there anyone who has this strange behavior?

  • The use of the battery has increased since the update to ios 10. Also, why can not disable the voice command. It's the most boring on the new update.

    The use of the battery has increased since the update to ios 10. Also, why can not disable the voice command. It's the most boring on the new update.

    Depending on what you mean by "voice command", either:

    Settings / general / accessibility / VoiceOver / OFF, or

    Settings / Siri / OFF

    As for your use of the battery, you can check what app pulls most of its use in the settings / battery.  A new version of the app is sometimes problematic, not necessarily iOS or iPhone.  If you see a unusual % of use of a particular application, or force-to leave it removal/reinstalling it or remove it until an update comes.  If anything seems unusual, it might be a problematic installation of iOS, in which case, you could backup your iPhone and restore it:

    My computer with two hard drives and 2 starting systems has the car crash in the solid state. When I got the new drive and tried to restore from time capsule, I lost some data. How can I see what backups are on the time capsule? My laptop is also saved to the time capsule. Everything is in 'Data' when I look through the Airport utility.

    Time Machine backup to a sparsebundle.

    The sparsebundle will use the share name of computer. So, it should be obvious who is your Macbook and that is your Macpro.

    Open the sparsebundle in Finder and keep open the subfolders until you get to the backup of each separate hard drive...

    You has of course set the exclusion in Time Machine?

    By default, Time Machine will exclude your second drive unless you have included it. Did you?

    Once you get to this level during the backup, you can do a full restore manually whenever you want.

  • Screen quality has deteriorated suddenly

    The next day my iPad screen Air quality has deteriorated.  He has ghost images and has totally lost the high resolution that I expect my iPad.  Looks like the old tv reports that allows us to get on the rabbit ear antennas!

    I did nothing else I know?  All parameters have not changed, nor have I dropped it.  Just, it started yesterday and that was before I upgraded to iOS 10.

    for any help or suggestion would be appreciated as I am 2 hours drive to the nearest Apple Store.

    Hello

    Try a reboot press and hold the power button / stop and menu button hold both down until you see the apple logo.

    It may take 30 seconds.
