Can I produce a frequency sweep a PXI-5652 from 1GHz to 2GHz and back down to 1GHz at a rate of 1KHz with RT?
I need to produce a triangular frequency sweep over a range of at least 1GHz. This sweep will start at 1GHz go up to 2GHz and back down to 1GHz and repeat the cycle. I need this cycle to repeat at a rate of 1KHz. The sweep must be as smooth as possible with the frequency steps being no more than say 1MHz. I have a RT controller chassis that I can install the PXI-5652 into. If I dedicate one of the processor cores to this function and reserve the second core for my data acquisition and processing do I have and chance or am I just dreaming?
Thanks,
Bruce Barnes
Hi Bruce,
If I interpret this correctly that you need to go from 1 GHz to 2 GHz and back to 1 GHz in 1 ms (you want to repeat this at a rate of 1 kHz) then this isn't possible with the PXI-565x series of RF Signal Generators. These have a tuning time of around 1-5 ms for one frequency step, and tuning from 1 G to 2 G in steps no greater than 1 MHz would mean at least 1000 steps.

How can I produce a report of the people asked to complete a form and their response?
How can I produce a report of the people asked to complete a form and their response?
Thanks. I cover four different sites. We are using the same questions for the four sites. Each site has a different client base (with different users). So I am inviting persons to complete the form in an ad-hoc basis following training sessions (so far I have trained 10 out of 57). The responses will be viewed by two or three Managers. The problem is that it is difficult to see who has started filling out the form, who has not even looked at it, and those who have completed it. So for example at the moment I have a zero response to my requests to complete the form, although some people may be working on the form?

I don't have a wireless printer, and want to print things off of my iPad. I know that I can use the iPad Camera Connection kit to connect USB devices like keyboards and I am wondering if I could do the same with a USB printer.
I don't think you can connect a printer since you won't have the printer drivers. I use FingerPrint from collobos.com to print to my non-AirPrint printers.

Log into the app store using the Apple ID you used to set your computer up. Look under purchases. If it is not there you may need to accept it or to unhide it

I'm using the Simulation Loop on LV RT when interacting with some hardware (i.e. all I/O is happening in the Sim loop). I'm going to conduct a frequency sweep test on the hardware and want to use the Simulation Chirp function. However, there is no way (that I can see) to trigger the Chirp to start at some event (i.e. I click a boolean on the front panel and enter a case statement). The Chirp is tied to the global time of the Simulation loop and so are it's input parameters. Is there a way to make it relative to some time at which an event happens?
Craig,
Your solution will 'cut' the beginning of the signal and only show the signal afterwards.
To control when the chirp should start, the best option is to use the Chirp Pattern.vi ( in the Signal Generation palette) and use a Lookup table to control when to feed the time. The shipping example (in LabVIEW 2013) shows how to code using a lookup table.
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Simulation\Signal Generation\SimEx Chirp.vi
Then, to start from a toggled boolean, look at the example:
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Simulation\Signal Generation\SimEx Step.vi
and Here is the example in 2013 (in attachment):

How can I use Automator or AppleScript to get text from a web page and paste it in execl?
I don't know how to make scripts or complexed automator workflows... that's why I'm asking.
I'm trying to make a simple app or script to ask me what text to extract from a web page, like name, address and phone number of a web page and paste each one of these data in the righ cell of excel.
I was thinking to promt a request from automator or an applescript to ask me which text to extract from the page or to look throught the HTML of the page to search for specific html tags, from which extracting text and then importing it, or paste it to the specified execl cell. Name in the name cell, address in the address cell and so on.
Can somebody help me to make this script?
If you know an alternative, like a software that already do this or another language to use, please tell.Try holding down the alt key as you mark the text to be copied. You can then copy columns to table text.

I got my iPhone 4 yesterday. I almost immediately had issues with it. I contacted Apple and was told to do a restore via iTunes online. I completed the restore and now my phone has an iTunes logo on it with an arrow pointing at the logo and a picture of a USB cable beneath the arrow. I can't get the phone to do anything else and I can't contact support because my phone isn't working. Can someone please tell me what I'm doing wrong? I listed the operating system below as "Other OS" because I don't know what operating system I have.
you do as the logo suggests: connect your iPhone to your computer and restore using iTunes.

I have a white 17' flat panel g5 imac power pc, I recently bought used. It had OS 10.5.8. Due to a storm the hard drive was damaged and I replace with new hd.
I did not get a system disc or other support discs with the machine. How or where can I find or download a new-install version of OS 10.5 or up to 10.5.8 that will work with the PPC? Thanks.Call the Apple Store and ask them to sell you a copy, you can then use the combo updater or you can buy a copy on eBay, but make sure it's the black retail copy and not a grey machine specific disc.

my imac 500g internal drive is nearly full, so i plan to add an external desktop drive. i also need to use time machine for backups--can i simply buy one large drive to handle both needs, or do i need a dedicated drive for the time machine?
thanks!I've racked my brain with this issue - done everything I know to do - and still I get this:
I've clearly moved everything to external drives except for 1GB of dropbox data that I keep across all my devices.
I've tried all of 'where did my disk space go' 's suggestions.
Terminal commands to disable local backup
What's interesting to me about this is that I do have 4.45 GB of Applications - is that “Other?”
I'm to the point where I'd like to wipe and start all over.. but that scares me! Suggestions?

I can't change font size. It goes only from 1 to 9 and can't enter an especific number.
I use Mac and for the first time I face this problem... I used to be able to enter the font size lik 32, 48, 96... any number in flash CC I can't. Is there any way I can change this? I looked in preferences and found nothing!
Hi Agda,
This is a truncation issue which we are investigating, however the functionality should work as expected as the size filed still has the information that you have entered say if you enter 12 you might see only 1 in properties panel whereas it has the value of 12 and your text on stage should get applied with 12 pt size.
Hope this helps.
Thanks!
