• Office 2013 on Win7 using bootcamp has delay time

  I use Win 7 teacher on a piece of Macbook Air 2014 with bootcamp 5 and MS Office 2013. Up to 4 weeks everything works well, and the performance was great. And then I got the delay time:

  -Closing remarks is the longest in about 4-5 sec

  -editig one Excel cell and switch to another will cost about 4 to 5 sec

  - and so on

  Thanks to this performance, it is horrible to work. I have also removed Office and install it again without any result.

  Anyone have some advice for me? Is there some patches in which software never cause this?

  Or am I alone with this?

  THX in advance

  Your is no longer in a Mac environment, if this side of "windows" because you're not virtualize, you run Windows as a complete solution for Windows. OS X doesn't play not any part of your experience. Windows as OS X should be updated with patches and update securities, the latter is the only support Windows offers for Version 7, it is out of development and was removed by Microsoft for more than a year. All compatibility fixes should come from Microsoft, see microsoft.com for the availability of these.

  Outside the correction and the issues pourraient be caused by:

  Disk fragmentation that is common in windows. (However it is not under OS X, don't defrag on Mac, OS updates will do everything if it you better than anything you can buy)

  hard disk-ragmenting https://support.Microsoft.com/en-us/help/17126/Windows-7-improve-performance-def

  Font management (again, on the side of 'Windows', your OS X fonts do not play in this)

  3rd party Windows applications, such as anti-virus and the litany of bloatware inherent with Windows. Windows has a startup mode for troubleshooting.

• measurement of the delay time to fall on the rise

  I use the PXI-5124 digitizer and development of codes in C++ to measure the time between the 2 channels.  I put the trigger on channel 0.   I need to measure the delay time of CH0 AMOUNTING to CH1 RISING, CH0 AMOUNTING to CH1 TOMBANT, CH0 FALLING RISING, CH0 TOMBANT to CH1 TOMBANT CH1.

  I encountered the following problems.

  1. when I tried inverted signals using the niScope_AddWaveformProcessing() function, I had to call NISCOPE_VAL_ARRAY_GAIN twice.  Second call with gin = 1.  Otherwise, the waveforms being feteched were not reversed.  This happened to both channels.  Here is the code I use.

  niScope_SetAttributeViReal64(session,"1",NISCOPE_ATTR_MEAS_ARRAY_GAIN,-1));
  niScope_AddWaveformProcessing (session, "1", NISCOPE_VAL_ARRAY_GAIN));
  niScope_SetAttributeViReal64 (session, "1", NISCOPE_ATTR_MEAS_ARRAY_GAIN, 1));
  niScope_AddWaveformProcessing(session,"1",NISCOPE_VAL_ARRAY_GAIN));

  niScope_FetchArrayMeasurement (session, "1", timeout, [channel] NISCOPE_VAL_ARRAY_GAIN, actualRecordLength, wave [channel], & wfmInfoPtr));

  Code that write the [vague] in a control file

  2. even if with above method to obtain a code reversed, I can't get a correct results of CH0 FALLS of CH1 RISING.   In addition, I don't know if the other delays are correct or not.

  Please see the attachment for the functions dgz_measure() and NI_DGZ codes::meas_delaytime();

  Other scalar measures seem ok.  I also tried the FFT, it should be ok too.

  What I've done wrong? Is there any sample code for the delay time?

  I checked the AdvancedMeasurementLibrary already.

  Hi, Jean Louis,.

  It works fine now.  He needs to call niScope_FetchArrayMeasurement after you set the attribute.  There is no need to call niScope_AddwavefromProcessing.  The niScope_FetchArrayMeasurement and niScope_AddwavefromProcessing will be peform the operation.  So if I called two of them, the operation will be twice.    Here is the code that works.

  niScope_SetAttributeViReal64(session,"1",NISCOPE_ATTR_MEAS_ARRAY_GAIN,-1));
  niScope_FetchArrayMeasurement (session, "1", timeout, [channel] NISCOPE_VAL_ARRAY_GAIN, actualRecordLength, wave [channel], & wfmInfoPtr));

  Thank you very much!

• The delay time indicator

  This should be the easiest thing to do, but I'm stuck for some reason any: I have a delay time running to a number specified by the user in seconds, and I want an indicator on the front panel, showing how much time passed. I thought that the "elapsed time" VI would be exactly what I was looking for, but I can't seem to get to do what I want. I have attached my attempt; If you can remember where I'm wrong, it would be much appreciated.

  You do not have a while loop, so your code runs only once.

  Your delay time runs in parallel with the timed.  So, it will delay the execution of the code.

  Get rid of the elapsed time and elapsed time and its indicator in a loop.

• Using more of a delay time in thread

  Hello
  I need to use two non-consecutive periods in a thread. My thread is generally as follows:
  1 tell an oriel MS257 to change the wavelength
  2 time delay #1 to give the MS257 time to change
  3 say HP 4156C to run the scan
  4 survey the 4156 C until the scanning is complete
  5 delay time #2 to 4156C time to load the data
  6 reading/analysis/backup

  My problem is that the second time delay seems to start counting immediately after the first: it does not wait for the scan to complete before the count. My VI is attached. It's a bit messy - organizational tips are also welcome!

  Thank you
  Ying

  Looking at the issue of sources: cleaning is a great tool (even thought it's far from perfect )

  Well, nevertheless, wireworking, it seems though the second express VI of delay must indeed wait loop ends. Therefore, I wonder why it is ignored. And the only reasonable explanation: you have an error on the cluster of error.

  So please debug using nail/probes on the cluster of error to make sure that you do not run the questions here.

  hope this helps,

• change the Timer class Delay time

  Is it possible to update the duration of the Timer class period while it is running. I want to update using the slider, but it seems not updated. I even stop the timer on the event cursor THUMB_PRESS that restart after his change. Doesn't seem to work that way either. Any ideas?

  I thought about it. Instead of setting a variable speed where the Manager works for the slider I directly changed the delay timer variable to equal the value of the slider. I feel stupid now, but it works very well.

• Disk error backup external hard Time machine

  Hello
  While that hurry to catch a flight, I accidentally disconnected my external hard drive (which I use for time machine backups) before ejecting.  Now the House, the time machine backup does not recognize my external hard drive.  I went into disk utility to try to repair the disk.  Here's what he said:

  I could really use some help as to how I should proceed.  Any advice?
  

  I think you need to clear this backup disk, and while you are this and do a full backup (which takes all afternoon to all night) you will be working without a net. If you do in idle time, and after checking your boot disk, the risk of catastrophic failure while the backup is low. Start now and in the future, you will have a backup.

  If you have a different backup disk, add it and Time Machine will create a new independent backup on it, and then Time Machine alternate disks automatically.

• There is Airfoil and Airport Express, latency/delay time?

  I want to be able to direct the output of my iMac "end 2014' 5K (10.11.6) on my stereo system (ParaSound P3/A23) using AirFoil 5 with Airport Extreme > Airport Express."

  But the audio output should be "real time." in other words, no delay or latency at all. Both are in the same room!

  I use notation software (Sibelius) and need to hear what I write immediately. Unlike streaming where I think there is an acceptable delay (2 seconds?) for the buffering?

  Is this possible please?

  If it isn't with AirFoil, any advice on how welcome :-)

  I want to be able to direct the output of my iMac "end 2014' 5K (10.11.6) on my stereo system (ParaSound P3/A23) using AirFoil 5 with Airport Extreme > Airport Express."

  With AirPlay (or Bluetooth), there will always be a form of delay or latency with streaming audio.

  In this scenario, an audio stream (on AirPlay) will go first to your iMac to AirPort Extreme and AirPort Express Terminal.

  To help understand why there will be delays, let's look at high-level "behind the scenes" about how works AirPlay:

  For the AirPort Express (AX), audio input is provided mainly by iTunes. Of course, it can also get feedback from other sources as you know, as of Rogue Amoeba's Airfoil.

  For streaming, iTunes or wing does most of the work. What is app reads audio content standard (AAC, MP3, audio books, Internet music streams, etc., it decompresses these file formats and creates what is essentially a raw, uncompressed audio stream.) This stream is compressed using Lossless Compression of Apple (via a QuickTime codec), encrypted with AES 128 bits and then listened (airplay) with an AXE. The stream is buffered for about 2 seconds until the stream is sent. The AX deciphers the flow, decodes and exports in a digital or analog PCM (using a built-in DAC) flows to its audio analog-to-digital versatile optical port.

  So, with the above, you can see that the tone does not simply move source to the destination without much more things. You will not be able to entirely eliminate the delay. Sorry!

• External backups Time Machine

  Hello!

  The MacMini to my dad, he has a backup storage more as external 4 TB Seagate and Time Machine recognizes it in the 'Options' from the settings page so that it can be part of the Time Machine backup.

  I don't have external storage but I do not use a Lexar 128 GB USB key to use to send files to and from school. However, in the 'Options' Menu, the stick is gray and I can't add it as part of the backup as the Seagate drive can. Someone at - it ideas? Is this something to do with the fact that the drive to Mac OS Extended format is 4 and my memory stick is FAT MS-DOS?

  Yes. Format the same as 4 TB drive. Disk utility and reformat the drive as Mac OS Extended journaled.

• external hard drive, because the camera into iMovie

  Hello

  I like to shoot loads of video and save these images on a hard disk to use later.  I just started using iMovie 10.

  Last night I tried to import video from my external hard drive... but... iMovie it reads like a camera.  Is very annoying because it searches the disk for video... but there's also a few records that might be inside other folders.  (I like to organize pictures by date... etc.)

  It seems to me that an external hard drive to be read the same as my hard drive... so I can click Open and navigate to the location I wanted, then select only the videos that I want to.

  Is there a way to change this?  It is not logical at all that an external hard drive is read as a camera. (See the image below.  Storage is not a camera! )

  Thank you!!

  

  If you copy a camera directory in the root of a disk-level external hard iMovie assumes that it is connected to a camera or SD card.  To avoid this simply move the video camera on your external drive folder in an enveloping folder.

• KEITHLEY 238 / NI GPIB-USB-HS-change delay time

  Hello

  I have a keithley 238 meters the current measures such as voltage is swept. It's the GPIB device and connected to my PC via NI GPIB-USB-HS

  adapter. I would like to control with Labview 8.6. I used the VI available at your instrument driver network who directed me to the website keithley and is attached below. Keithley said that the VI is unsupported freeware. The VI is located at

  http://www.Keithley.com/products/CurrentVoltage/?path=238/downloads#1

  The first "sample program" on this site Web is the VI that I use.

  Now the VI works well.  The VI sweeps the tension and shows the current measured as a table and a chart.

  I want to just change the scanning time, but I can't increase it beyond 1000 ms. Why is it so?

  Scan delay is the time that he made a break after each increment of voltage.

  I don't know if there's a change in the VI or NI GPIB-USB-HS adapter settings are a problem. I checked the settings of this device under MAX - time settings are the following

  (1) time I / O-> by default set to 13 (10 sec)

  (2) antipolling - verified

  (3) then there are a few termination settings and advanced settings, there is a setting, bus game calendar to-2 (500nsec)

  So are bad parameters GPIB or code needs to be changed? How and where to change the code?

  The reason why the VI will not attribute to a value greater than 1000 is simple to understand. Just right click and select data entry and you will see that the maximum value is set to 1000. It is set so that I don't know. Have you looked in the manual to see if 1 s is a limitation of the instrument?

• Adding a delay time and reading a file

  Hi there, new to labview here. Working on a project and having some problems he do on the ground.

  First question, in the VI below, I try to have a delay between each entry, but when I take a glance on the control of delay, I don't see how it is supposed to implement. No singal flow through the timer.

  Question 2, I want to write these ports via a xcel file but not sure how to do...

  Thanks for your help in advance...

  It seems that Excel adds additional bytes in it for who knows what reason.  Save your spreadsheet as a CSV file and they seem to go away.  Of course, you must change the format '% x, %d' string when you do this.

• Keithley scan 2000 delay time

  I'm updating some legacy in Labview code that was written for a Scan Keithley 2000 DMM with 10 Channel relay card.  Right, the code now contains a delay between selection of a channel of meter and read the data.  The time is 1 second.

  I could not find any supporting documentation why this delay must be put in place.  It's just for debouncing?  If Yes, does anyone have any experience which suggests could be shorter?

  Thank you.

  The time depends on your system. For debouncing 20 ms is more appropriate.

  But you can try. Build scans between max, min and weak signals and see how fast the system gives the right answer.

  Another reason for delay is the automatic selection of the DMM, sometimes that takes some time and also the load on your system should stabilize.

• How can I draw the intensity in real time of a picture in time real (imaq 1394)?

  I have a firewire camera.

  I hooked up my camera to my pc with labview and now I display image in real time. How can I draw the intensity of a region dependent on time?
  Y - intensity
  X - time... I would watch the variaions real-time intensity...

  Thanks in advance

  The light meter example is pretty much what you want to do. It is located here:

  \National Instruments\\examples\Vision\2. Functions\Light Meter\Light meter Example.llb\Light meter Example.vi

  In the example, the x axis are the number of iteration, but it is easy to modify to use a graphic instead of a graph and chart the time instead.

  Hope that helps.
