Use of NI6711 card.

How I have asked before, i need generate four signal:
1) One sine- wave signal from 0 to -4 Volt, and frequency less than 100 KHz.
2) One trigger signal, amplitude 10 V, frequency 3200 Hz and pulse- width from 1 to 10 micro Seconds.
3) Two trigger signal, amplitude 5V, frequency 0.4 Hz and pulse- width 20/70 mS in opposite phase.
4) Two square wave signal amplitude 5V, frequency 2 KHz, in opposite phase.
For this application I have thought an Ni6711, used at follow mode:
One of four analog output to generate the first signal.
One other of three free analog output to generate the second signal.
Two of 8 digital I/O for generate the signal at the third point.
The counter/timers output to generate the two signal at the point four.
But Felipe in his answer (tanks Felipe) sayng that regarding my third signal requirement,
I need to have two more counters to do that. He saying that because, the digital lines
of that board don't have strobed, operation capability.
My new ask is that:
Can I use for generate the signal at the third point the two remainder free analog output?
in stead of two of 8 digital I/O?

You can do that. As the frequency of the pulse train you need is not high, you can rely on the Analog Output channels to accomplish that. That is a good idea.

    I need generate two signal, the first are an trigger signal, 10 V amplitude, pulse width 10 micro-seconds
    and two possible frequency (user discretion) 500 Hz and 3200 Hz.
    The second signal is an triangular wave, amplitude between 0/-4V, this signal must be in phase with the first, and its frequency must be the frequency of first signal multiplied for 5
    (for example if the trigger signal is 3200 Hz, the second signal must be 16000 Hz, in phase with the first signal).
    Is it possible generate these signals with two analog output of Ni6711?
    Can I generate contemporary of the two signal above
    two TTL signal, one trigger 0,4Hz/70mS pulse width and one square wave 2 KHz means the two counter timer of Ni6711?
    Can I use Visual Basic to manage Ni6711
    card for this work means an DLL?

    Yes, you can do that, but to generate the triggered TTL pulse train, you will need to use a 660x board together with the 6711.
    I'm saying that because the counters of the 6711 board, don't have triggering capabilitie; and the counters of the 660x do.
    As you need synchronization, you will need to connect both boards together by using the RTSI cable. Once that is hooked up, you can definitely use Visual Basic and NI-DAQ dll function calls to accomplish that.
    Hope this helps.

  • How can I set up different profiles (accounts??) using the credit card?

    Each member of my family would like to have there own itunes profile (or account??), but we'd like to use the same credit card. Is this possible? Does each family member need a unique email address for log in.

    So my sister and I have our own separate iTunes accounts, and she has her set up with her credit card. She let me use her credit card on mine but it keeps saying the security code is invalid. Then the credit card company called about her credit card activity. Are you sure it's not impossible to use the same credit card on our different accounts?

  • Why can't I just use my debit card for adding my child to family share?!

    I want to use my child on family share but can't because I don't need or want a credit card, my bank has fraud protection, who actually just called me about fraud because I purchased the newest iPhone! I don't like credit cards. Why can't I just use my debit card as usual? Kids can get credit cards just as easily as they can debit cards! This is ridiculous. Why isn't there another option to verify I am the parent?! I am so beyond angry right now. Like I am being punished for not owning a credit card!! Otherwise there will be another way to do this. A person should have the freedom to use their chosen form of payment without missing out on all the options available. Honestly even if I wanted a credit card I haven't enough credit because of past mistakes. So this is not making me happy at all.

    Mad Parent,
    I feel your pain. We refuse to have credit cards, too; yet it's required in order to create a child's apple id. I will most definitely be leaving feedback with Apple. This is absolutely ridiculous that we can't just use our debit cards! Mine is a VISA. I use it to make CREDIT CARD transactions everywhere else, why not be able to use it the same way here!?
    I just had to restore my sons phone because he forgot his 4-digit password and got it disabled. I didn't have it already on my itunes so my only option was to restore it. I wanted to create his own apple id so he didn't have to keep using mine. Because every time he downloads a new game it automatically ends up on MY device as well, not just his. Anyway, he needs his own apple id. But, apparently, that won't be happening until Apple gets their heads out of their butts and figures out how to serve ALL of their customers!
    Equally Mad Parent

  • How do I use my gift card instead of my credit card?

    I have always used gift cards to buy my music off of Itunes, but when I recently used it I only had 25 cents left. So when I clicked on the music to buy it, it showed me all of my account information and asked for the security number to the credit card that I have listed under my account. But my parents didn't want me using their credit card, so my mom bought me some more gift cards. I redeemed the money on the cards, but for whatever reason it still takes me to the "Billing Info" and asks for the security number, even though I have money already in my account from the gift cards. Until then, I am unable to purchase any new music. How do I switch back to using my gift cards and not the credit card?

    It is a security measure that has been implemented in iTunes.
    When it asks for the security info on the CC, make sure to uncheck *Do not use this card for this purchase* (or something similar).
    It will then use the gift card for the purchase.

    Hi ..

  • HT5622 I want to use free apps on my Ipad and do NOT wish to submit a credit card to Itunes.  My Apple Id works, but won't let me migrate past the credit card phase in itunes.  I don't wish to sumbit or use a credit card because I will not make purchases.

    I want to use free apps on Ipad 2, but it continually asks me to submit a credit card in Itunes.  I do not wish to purchase anything apps or music.  I am only interested in free apps.  If I were to make purchases, I would use a prepaid card like an itunes card or an app card, but NEVER a credit card.  I can't seem to bypass this option of using a credit card and need to.  I have another Ipad 4 and have never needed to use my credit card to migrate past itunes to use any apps.  How do I get past this credit card request and still use my ipad 2.  According to my Ipad 2, if I don't plug in a credit card, I can't even use free apps which is stupid.

    8. Create and answer your secret question
    9. Select NONE for Payment Method
    10. Fill in Billing Address
    11. Submit application for new Apple ID
    12. Wait for verification email

    If you have a credit card on your account then it has to be a valid card - do you get the 'none' option on your account so that you can remove the card, or is there an error show anywhere on the card payment details screen so that you can correc it ?
    As long as you are buying content for yourself and not trying to gift, then your balance should be automatically used for its purchase.

    I bought an iTunes gift card, reedemed it, and when i try to buy a game it doesn't let me use my credits, but instead I have to buy it using my Visa card?

    What exactly do you see when trying to buy a game, what messages do you get on-screen ?
    If it's an account that you've just created then unless the instructions on this page are followed when creating an account : Create an iTunes Store, App Store, or iBooks Store account without a credit card or other payment method
    then credit card details will need to be entered before the account can be used to download any item from the store. You should be able to remove the card after entering its details.
    If you are getting a prompt to review the account then you could see if this post by mountaingoatgirl lets you do so without needing to enter credit card details :

  • Can I use a debit card to set up family sharing?

    When setting up my family sharing it will not let me a create Apple id for a child under 13. It says that I have a debit card and to add a credit card. I don't use credit cards. If this is only for age verification why would it matter? I tried both of our cards on different accounts and still no luck. On my bank account it shows up as pending $1 each time I try. I called Apple support and they didn't know a way around it. I asked if a prepaid Visa would work. They thought it should. I bought one and tried it but no help. To set it up they require my birthday, social security#, address, phone number. With all that it should of verified my age. I really wanted to use the family sharing feature since I updated all our iPads to os8 with the newest update. They were all under my Apple id before. My bank suggested adding MasterCard secure, so I did but that didn't help. Any suggestions other than get a credit card.

    Here are the accepted forms of payment for your Apple ID. There are alternatives to using a credit card. Many people use an iTunes gift card. You can purchase one almost anywhere.
    Credit cards
    Content codes
    Store credit, including iTunes Store Gift Cards, Gift Certificates, and Allowances
    UnionPay (requires SMS PIN for setup)
    Payment methods you can use in the iTunes Store, Mac App Store, App Store, and iBooks Store - Apple Support

    Hi everyone,
    As you can tell from the topic of the discussion, I was just wondeirng if there's any way to use a gift card to pay off a credit card balance?
    It's not a huge problem as I only bought one song, lol, but it'd be nice to know if I can use my gift card to pay off the balance. I forgot to redeem my gift card before purchasing >_<. Smart I know. So please, if some one knows the answer to reply back. Thanks!
