How to send a ttl signal with a good exactitude less than 10ms?

i have a pci 6013 (8 input channel) and pci 6711 (4 outpout channel).Then i need to send a ttl signal to a camera ccd to take a photo when a waveform sinus is equal at zero (rising), but when i send this TTl signal with dasylab using generator pulse or combi trigger and readind this signal, i have difference between dasylab pulse(that is exactly) and measurement pulse that is approximate 40ms after.But i need to have less than 10ms is it possible?
Frequence rate =1000hz and block size=512 the waveform sinus is 0.2Hz.i have already try to increase the sampling rate but nothing happens.Thank for your help.

Yes, it's possible.
You just have to reduce your block size to 10 !

How to send a modulate signal by the NI PXI-5441?

How to send a modulate signal by the NI PXI-5441?
I am using NI PXI-8108 / PXI-5441.
I want to send a binary signal modulated (FSK) by the 5441. I tried to use, without success, the modulation VIs with the Fgen VI.
Thanks

Hi Mauro,
the code structure is similar to any structure of I/O. You need open the communication channel with the hardware (using VI Open), use VI Write/Read to send/receive data and close the reference (VI Close). You can look the structure in LV examples.
Nevertheless, if you cannot, post your code that I analize to you.

How to send a sms email with a 5310

I am trying to figure out how to send a Sms Email with my new 5310 xpress music it only allows me to enter numbers in the to box

i would guess that you are trying to write the message possibly in the field designed for a contact name or phone number that you would like to send it to, if you go down to the rest of the lines you will be able to type your message. this is just a guess but it sounds like this might be the issue. if not please elaborate so we can assist you better.

How to measure a current signal with NI 6211?

How to measure a current signal with NI 6211?

Hi Clecio,
This is a charge accelerometer. It is different from the IEPE accelerometers that outputs a voltage signal.
You need a charge amplifier. Then according to the charge amplifier output we can select an appropriate module to measure the signal.
It is not possible to measure charge accelerometers with NI 9234 directly.

HT1212 My ipad mini has been crashing a lot recently so I started a system reset. However, it's now stuck with the progress bar less than a quarter gone: this has been the case for several days now. I have tried resetting from itunes but it needs the pass

Now it's stuck with the progress bar less than a quarter full. I have also tried resetting through itunes which works right up to the point where itunes states that it needs the passcode to be inputted into the ipad to connect to it. At which point it then sticks at the same progress bar point. HELP!! please, this ipad is really important to my work.

Well the term "hotlined" I have never heard before. In any case many states (like NY) just passed regulatory powers to the State Public Service Commission of which it may be called something different in your state. You could file a complaint with them. Or file a complaint with your state attorney generals office, they also take on wireless providers.
The problem here is the staff you speak to are poorly trained, in days gone by it took one call to them and they pulled up your account and see the error and had the authority to remove any errors. They did not remove legitimate account actions, but used their heads instead of putting a customer off or worse lying to the customer.
Its a shame you have to go through what you going through.
Good Luck

Rogers is saying that IOS4 won't allow use of the personal hotspot with a plan of less than 1GB data. I say it's a policy of theirs, not an iOS restriction. Anyone know the truth?

I call BS but the tech guy was insistent that the iPhone can detect what plan I have and won't enable the feature and there's nothing they can do about it, short of selling me a larger data plan...

Actually it does. It's wrong to lie to a customer. By blaming Apple, they shift the blame and make it seem like there is nothing they can do about it. If they admitted it was their policy, I could complain and try to get it changed or I could move to another carrier.
If a person killed someone and blamed it on a heart attack, the person is stil dead, does it matter? Either way they're dead, right... (extreme, I know, but illustrating a point)
Wow.
It is certainly Rogers policy and is not unusual at all among carriers.
Seems like a non-issue to me, but apparently being "lied to" ( perhaps the employee was simply mistaken, it happens) is a major deal to you.

How to send a packaging request with a multiline description

If I try to send a package request with this metadata description:
<dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">First Line
Second Line</dc:description>
Notice there is a carriage return between "First Line" and "Second Line".
Then, the server will return a E_ADEPT_DISTRIBUTOR_AUTH error.
If I remove the carriage return the packaging is done well.
I would like to know how to send the multiline description or if it is not posible.
Thanks in advance.

Hi,
It's not the faxformat in ITCPO.
What I figured out by comparing my program with another program (printout of balance sheets) is that this other program is able to fax or to print but not at the same execution. When you execute the balance sheet program in order to fax, the sapscript formular is created with the printer POSTSCPT (driver: POST) and code page 1117. When you execute it for printouts another printer can be choosen and the code page is 1110.
Could this be the problem of not beeing able to fax an existing spool (sapscript) request? Or is there a way to convert the OTFDATA from code page 1110 to 1117?
Cheers,
Thomas

How to convert a baseband signal with bandwidth 20MHz to an RF signal with center frequency 2.4GHz and the same bandwidth 20MHz

Hi,
I was wondering how to convert a complex baseband signal with bandwidth 20MHz to an RF signal with center frequency 2.4GHz and the same bandwidth 20MHz in simulation. I tried
1. Multiplying the complex double type baseband signal (1-D array) by exp( j * 2 * pi * 2.4E+9 * T ) where T is the symbol period of baseband signal.
2. Usage of MT upconvert baseband but doesnt keep the BW constant
Looking forward to your help.

I should add that you can multiply your baseband signal with two carrier signals that are shifted by 90° and then add or subtract the result to obtain upper or lower sideband only. You can try to search about IQ moduilators/demodulators to learn more.
Cheers
Edgar
