several segments of the production of a signal as a signal of undivid

Hi nice friends.

I work on a simulation of signal with LabVIEW, all work good and fair execution problem a signal.

It's a signal sine, its changes in frequency of 15 Hz - 30 kHz smoothly. At first, I thought it would be easy to build a whole and output signal with the DAQmx Timing.vi (use of wave), but things does not seem simple, due to the high frequency (30 kHz), should I do the sampling rate of the wave at least 300 KHz, which again is not the pretty smooth waveform.

So I was wondering, if it is possible to the waveform of the output in the form of several segments and their output without interruption. Yet I wonder if it is possbile to do with this big (30 kHz) frequency?

Thank you all for andvance.

Best regards

Hi GerdW,

Thanks for the mention me.

I made a simple diagram as follows

It is to generate a samples of the series (this is 100 #s) of a sinusoidal signal, before the release period, set the sample as continuous sample clock and frequency of 15 Hz starting, then write it, the material will be guard wirte until the task is stopped or deleted. Now that physical custody write this 100 samples, I change the sampling frequency with the DAQ Timing.vi in a loop, the frequencies change quietly.

I hope I made clear.

Best regards

  • Recommend products OR for my application (controlling several instruments at the same time)

    I'm new to Labview, currently only using the trial version.      There is money in my budget to buy control software, but I need to qualify my needs.

    What I try to do is to control several pieces of equipment to test as a single system, which allows me to perform automated on conventional measures

    and digital two way radios.

    Here is a list of the material I want to control:

    First of all, my controller is a & Rohde Schwarz 3 PSL.   Fully GPIB active and ready.  It is the PC control software will reside on.

    Equipment:

    Spectrum analyser Rohde & Schwarz FSEA 30 with modulation analysis package digital option B7

    FSEA 30 second, same configuration

    R & S AMIQ4 I / modulation generator Q (files of the software residing on the PSL3)

    Generator of analog signals from R & S SMY 02

    Agilent E4431B analog-to-digital signal generator

    Agilent E4406A spectrum analyzer/digital radio test set

    E4418B Agilent RF wattmeter with sensor

    General Dynamics R2670B service monitor

    A typical application will be a test of classical radio on VHF or UHF analog channel.

    The idea is to enter pass and receive frequencies through Labview or any software is best suited for the job, as well as modulation parameters.

    and have the following things occur: assume usage of 150,000 MHz with a FM frequency modulated 1 kHz sounds modulated to the deviation of 2.5 KHz

    in total, with your 127,3 Hz subaudible to a gap of 300 Hz

    Test phase of receiver: send commands to control of instrument of Agilent E4431B signal generator.   Level set to-60 dBm.  Set to 150,000 MHz frequency.  Set

    Audio 1 to 1 KHz and audio tone 2 to 127,3 Hz at a level of 8 pecent of your 1.  SD total do not exceed 2.5 KHz.      Inject the test signal into port RX

    on the radio.

    The value R2670B SINAD function, related to the radio via the audio output port.

    Signal level to ramp down to the SINAD falls to 12 dB.

    Increase the level of the signal to the attenuation of 20dB.   Measure the audio distortion.

    Testing of transmitter: using the attenuators appropriate necessary on the analyzers of spectrum, and/or using a switched network of wiring.

    place radio to transmit using above specifications frequency and modulation.    Analyzers to receive on the frequency designated value

    and measure the transmitter specifications, including nonessential radiation measurement and harmonics.    Measure actual output power

    Via E4418B-power meter.

    I use two monitors to perform multiple tests in a same transmission. One is optimized for spectral purity tests while

    the other analysis of modulation characteristics.    Frequency, duration and RBW are defined according to the needs.

    When you test a digital radio, the signal chain is slightly different.  The AMIQ I / Q modulation generator s I / Q outputs are sent to the

    I / Q inputs on the Agilent generator, the power is on to accept external I / entered Q and the FSEA Spectrum Analyzer (an a)

    the) is passed to a preset that implements all relevant digital parameters so that it can be used to directly evaluate the digital transmissions.

    It is not a very developed in the planning system, but I do not know now whether Labview is everything I need or if I'll need to Teststand or another

    software packages.

    I'll probably want to ask for some advice on how to get this set up, eventually.

    LabVIEW is more than capable of this task. That's what it was designed to do. Use the help > find the instrument Drivers to find and install the drivers that you can use to control and read.

    TestStand generally requires the use of a programming language. It runs the tests that you write and provides functionality built for the production of record and report database then you would need to write these modules yourself with LabVIEW fair and some add on box to tools. For a single test configuration, it is perhaps an exaggeration, but it is interesting to watch as an addition.

    Hello

    Partitioning your disks for ASM configuration as 'A' might make sense. If you lose one disk, you have the discs to another.

    'B' totally make sense if you have lost the disc that you have lost all group ASM and you need to change this with something like 'C '.

    But obviously you need redundancy ASM configured appropriately.

  • Cannot migrate VM between 5.5 ESXi versions: the version of the product to the destination host does not support one or several CPU features

    We receive an error message that I am trying to make sense. I understand very well the notion of compatibility, CPU, CPUID, masking and so on, after working on a competitor hypervisor. However, this error seems wrong (or needs better wording) based on my understanding:

    Here is the message:

    ----

    A general error occurred: the version of the product to the destination host does not support one or several features of the CPU currently use by the virtual machine.

    Characteristics of CPUID level 0 x 1 'ecx' register are indicated with a '1' bit: x00x:xxx0:xx0x:x 000: x 0 11xx:00: 00xx:11xx

    ----


    This happened during the migration between two hosts ESXi with the same physical processors - in this case, a Westmere X 5650.


    The source host is on ESXi build 2068190 (5.5). The destination host is on ESXi build 1474528.


    The bits it seems to complain are:


    DTES64

    Monitor/MWait

    Cx16

    PDCM

    The punch line seems to be: "the product version of the destination host. However, I have trouble believing that support for these features have been added to ESXi between the two versions. If it were, VMware has been certainly silent about.

    For what it's worth, explicitly set us the CPUID masks in our virtual machines (no, CVS is not an option for us at this time.) This is the mask:

    CPUID.1.EAX = "00000000000000100000011001010001".

    CPUID.1.ECX = "00000010100110001110001000111111".

    CPUID.1.EDX = "10001111111010111111101111111111".

    CPUID.80000001.ECX = "00000000000000000000000000000001.

    CPUID.80000001.EDX = "00101000000100000000100000000000".

    cpuid.d.EAX = "00000000000000000000000000000000".

    cpuid.d.ECX = "00000000000000000000000000000000".

    cpuid.d.EDX = "00000000000000000000000000000000".

    Note that the bits of the message complains (2, 3, 14, 15) * are * in fact forced to '1' in our mask of cpuid.1.ecx. That means (if I understand correctly), ESXi does not have the virtual machine unless the host processor supports the feature. And in our case, the virtual machine will start with happiness on nodes, with both versions. It will be not simply migrate between them.

    So, long story short, is this a bug of ESXi? The error message is misleading? I understand something?

    Thank you


    Matt

    To use the masks feature VM in this way, you must replace all the 1 to your masks with-'s:

    CPUID.1.EAX = "00000000000000-000000 - 00-0 - 000-

    CPUID.1.ECX = "000000-0-00--000---000-000---".

    CPUID.1.EDX = '-000 - 0-0 - 0-

    CPUID.80000001.ECX = "0000000000000000000000000000000 -"

    CPUID.80000001.EDX = "00-0-000000-00000000-00000000000.

    cpuid.d.EAX = "00000000000000000000000000000000".

    cpuid.d.ECX = "00000000000000000000000000000000".

    cpuid.d.EDX = "00000000000000000000000000000000".

    Zeros erases the features that are not available on your hosts Westmere, and dashes will leave the other one features.  The problem with those masks was forced to you certain features on who would have normally been off.

  • Satellite L450D - cannot use the product recovery disc

    Hello

    I'm new to this forum and have spent 3 days reading this and other forums to try to solve my problem, I found a lot of answers, but none does not work for me so I'd see if I could get the thought some very great need help here.

    Now, I have the problem that when I start the laptop the windows logo appears, then Microsoft corporation through the bottom and then the screen black with the cursor of Pentecost, I tried all possible starting in the bios settings and just goes back to this screen, I can t get no prompt or anything like that , I used knoppix and managed to transfer all the files I need from my external HARD drive, so thought I would not reset to factory settings with the recovery disk of the product supplied with the notebook, the disc never has been used or taken from the package until now is so in perfect condition of the art, so I put in the drive , start computer press f12 and make the primary boot CD, but all that happens is it says windows is loading files and get back to the dreaded black screen and a cursor.

    Can someone please help?

    If you have the original Toshiba Recovery disk I assume you have older model laptop with Windows XP Home edition old. To be honest, it would be interesting to know is you.

    In any case, out of curiosity but can only begin preinstalled OS in safe mode?
    Enter the BIOS settings and set its default value initially. After ding this change BIOS boot order and place the CD/DVD as first boot device. Put recovery media in the optical disc drive, and boot up your laptop. While the laptop tries to start C press several times.

    Usually, this should force your laptop to use ODD as the first boot device.
    Long ago, I had similar problem and such combination helped to force the ODD to read the recovery disk and Windows XP Home edition recovery facility. Of course, I hope that everything is OK with your HARD drive.

    Please test and send feedback.

  • Satellite A200 - cannot use Vista after the recovery of the product

    Hello. I hope someone can help me with the following... This week I had various issues with which follows my laptop a Vista update that system restore did not fix, so I decided to go for a full recovery of product (which I have a complete backup of all my files).

    So far I have used the product recovery on my laptop in the 3 ways I can see (and more than once): without changing the settings, change the settings and maximize the partition, change settings and select advance / expertise.

    Whenever I was able to complete the initialization of windows, create a new user account, etc. Once the Office has been set up, I get a small window with a progress bar and when it's over, I click on the button 'restart '...

    After the reboot, I get the black screen that says Microsoft Corporation with the green progress bar, but he's there for what feels like 'too long '. After a while, I get a black screen with a cursor, then a blue screen for a crash dump.

    If I use F8 and boot mode safe, the system stops the CplIR.sys file, although the hard disk activity seems to be continuing. I turn off after 10 minutes.

    If I use F8 and then select Repair computer... This is what is happening with each option
    -Restore the full windows operating system: after clicking on OK nothing happens.
    -Diagnostics of memory: there is no problem with memory
    -DOS prompt: I run CHKDSK and there is no problem with the hard drive
    -Restart: there is no errors, even if the word diagnosis 'impossible' when he sees, there is no system restore points

    Then on reboot I get the black screen with cursor followed by the crashdump OR if I managed to log in and access my desktop, I get the crash dump, as soon as I try to do something (like open Control Panel).

    Following the instructions found elsewhere, I have tried this after removing the battery, then changing power management options immediately after the initialization of windows (ie. before clicking on the restart button). No change.

    I even ignored the button restart! But still get a crash dump, when I try to do something.

    Any ideas? I've got past (ie. wasted) so a lot of time on this and don't understand what may be wrong after formatting the windows drive image and reloading...

    Hello

    It's very interesting story. I got several notebooks several times but I never noticed anything like that.
    I must say that what you did right and you think appropriately. If I were you I would try exactly the same steps to make it work somehow.
    I do not know which issues you had before, but I imagine that here it's just the problems of software and not important for the operation of the equipment.

    It's really hard to say what can be the problem. What you can try, is somewhere to get facilities Microsoft Vista disk and install naked Vista to see if the same thing will happen again.
    Anyway, the fact is that images of recovery are tested and adapted for each laptop model and if the material is OK there no reason for this kind of behavior.

    Try again with the new installation using Microsoft facilities drive and let us know exactly what is happening.

  • Problems of the product on the Satellite Pro A200 recovery

    Hello

    I have a Satellite Pro A200. She runs very slowly and sometimes it crashes when I connect.
    Also the homepage was hacked and I tried several anti-spyware and they did not work.

    I have the product recovery disc, but the problem the DVD rom drive stopped working.
    The light is on, but it will not open unless you use the manual unlocking.
    I removed and checked the connections, but it seems okay.

    The CD-ROM/DVD-rom has disappeared from the Device Manager and does not come under the material.
    I tried the system restore, but it won't work.

    Is there anyway that you can use the product recovery software if you start from a USB?

    I tried to restart the computer and choose boot from CD, but it won't give me this option.
    I looked in the bios and only boot options it gives are hard disk, CD rom, land and FDD

    > Is there anyway that you can use the product recovery software if you start from a USB?

    No, this Toshiba recovery disc cannot be copied to USB flash memory and used for installing the OS. I'm afraid that it would work not m.

    But if you have a Microsoft Windows CD, you should be able to create a USB bootable flash stick. In internet, you will find lots of useful instructions step by step how create this bootable USB key.

    But boot from USB flash memory stick must be definitely possible since the BIOS supports bootable devices on:
    Drive floppy USB, HDD, ODD, Network (LAN), USB memory

  • Re: Several questions about the recovery of the Satellite L750 features

    I have several questions about the recovery of Satellite L750 features available to it. Any help and answers would be useful.

    (1) when I started the laptop first, he asked me to create a recovery CD incase I need to reinstall the operating system. But he also said that he built in the recovery partition, so therefore, I have to make a recovery cd or not?

    (2) will be the recovery CD is exactly the same as the recovery on the system partition?

    (3) is the partion of CD or recovery includes all the integrated software pre-installed with the laptop?

    (4) also in the device manage management it shows watch partion recovery but it is empty, is it true?

    (5) in the second partition (drive D) system, he has a record with what looks like the recovery of files and folders. Is it safe to move/remove it?

    Hello

    I'll try to provide answers:
    1 - to ensure that everything works perfectly you don t need these discs, but if something goes wrong with the HARD drive you will not be able to do anything. When you have the recovery DVDs, you will still be able to install the recovery image and once again the factory settings. So my advice to you is: create these discs as soon as possible. Use only on DVD-R media and buy products of high quality (TDK or Verbatim).
    2 - Yes.
    3 - Yes.
    4 - No. Don t be confused with this.
    5. in a first time create restore DVD, and later you can do what you want. I put t know which files mean you but don t touch anything before that of the recovery disks to be created.

    In the past, many people have been experimenting with the structure of HARD drive and partitions and later was surprised when installing disk recovery HARD has been damaged. Don t make the same mistake.

    If you have any other questions you are welcome.

    Hello, Jeff

    At first, I must say that it is not toshiba Help Center, but user forum created by Toshiba, so if you wait for the response from Toshiba people here you are in the wrong place.
    In any case, in this forum, you can pick up some very useful information and a lot of people here can help you with your problems.

    Return to described the issue.
    Unfortunately you do not understand how it works with the product key and Windows Setup, so I'll try to help you with this.
    Each computer toshiba laptop comes with preinstalled operating system (recovery image) and the product key at the bottom of your laptop belongs to this version. With other words: when you buy the new laptop, you have to pay for hardware, operating system and a license for this preinstalled OS. Product key at the bottom is not a kind of universal product key and cannot be used for activation of another version of Windows.

    You can use the delivered Toshiba recovery disc that contains mage replicated several times and each time you will have activated the operating system. When you use the Microsoft disk for the installation of the OS you must have valid product key which belongs to this particular version.

    In your case product key is for Vista, and you cannot use it for Win7 activation. This product key is... unnecessary.

    If you have any other questions you are welcome.
