Can pci-6251 output a stable sine waveform with 50mV Vpp and frequency is 150 hz,1000hz,3000hz?

i tried .while the result waveform is not stable and the frequency is always changeing all the time. Any way to improve it ? thanks so much !

Hay thnx dude..
I found the example and now it works
once again thanks a lot

Is it possible to display a waveform with fixed length and fixed starting point?

Hi,
I am using DAQ assitant to acquire voltage and current measurment of my device. The voltage is a pure sine wave and current is a periodic waveform with phase difference and distortion. I use waveform chart to display the waveform of voltage and current waveform in seperate charts and they work fine.But the waveforms look like moving to the right all the time, in another way ,the phase is always shifting. Now i want to display the waveforms of both with fixed length (say 2 cycle) and also in a same chart. Apart from that, i also want to display the voltage waveform starting form 0 degree (a fixed point )rather than moving all the time. In this case, i can observe the angle difference between voltage and current. Is there any method to achieve this purpose?
Many Thanks,
Hao

Hao,
first of all, you are using a chart which has three options for updates if the chart is "full":
Strip chart (default)
Scope chart
Sweep chart
These are called "update mode". Test the modes yourself.
Also you have to know that you will not likely have an integer number of periods of your signal in the display of the chart. Therefore, a continuous signal will "move" the graph from update to update.
You can implement some algorithm to discard data to maintain a static "trigger" level for display, but as stated, it will leave gaps in the signal. These gaps are not a concern unless you use the displayed signal for analysis (e.g. FFT).

You can however share or import content from another library/account using homesharing.

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO?

How can I implement a Digital I/O counter with a maximum source frequency of 80 MHz (like 6602 board) using CompactRIO? It appears as if the Digital I/O modules for CompactRIO are much slower than this.
Thank you,
--Ray

Hi Ray,
The highest frequency input we offer for C Series modules is 20 MHz if you are doing LVTTL and 10 MHz for 5 V TTL. These modules are the 9402 and 9401, respectively. Unfortunately, there is no 80 MHz input on this form-factor.

Can I use iTunes Match on my Sonos with my iPhone and iPad?

I have Sonos. No, it won't use iTunes match. It will allow you to stream your itunes media, but only the files you have on a hard drive on your network.
ETA: It does let you play other internet services such as Spotify though.

How to generate and output 3 TTL square waveforms with different pulse widths using counters of NI 6034E

Hello
I just have a few questions.
I am using the NI 6034E DAQ board in order to
generate simultaneouly 3 different TTL digital signals, with different
pulse width, and output these TTL signals to an external circuit that I
am using for this application.
The following pattern of the TTL pulses will look like this:
01010101 01010101
00110011 00110011
00001111 00001111
From
what I understand, I have to use the 2 counters, Ctr0 and Ctr1, to
generate the TTL pulses that I desire, because the DIO lines are
software timed only and I will not be able to produce a deterministic
output period using these DIO lines. Am I correct?    Also, do I have
to use a separate counter to generate a separate TTL digital pulse. I
need 3 different TTL pulses and there are only 2 counters for this DAQ
device. The three generated TTL signals will be feed to an external
circuit. Concerning the hardware connections for my application, I
assume that the generated TTL signals will be output from
GPCTR0_OUT(pin 2) for counter 0 and GPCTR1_OUT(pin 40) for counter 1
of the NI 6034E. Is this correct? Is there any way that these TTL
signals can be output from three DIO lines(DIO0...2).
Here is some code that I plan to use in order to do this:
#include <NIDAQmx.h>
static TaskHandle gTaskHandle = 0;
DAQmxCreateTask ("", &gTaskHandle);
DAQmxCreateCOPulseChanTime (gTaskHandle, "Dev1/ctr0", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 1.0, 2.0, 2.0);
DAQmxCreateCOPulseChanTime (gTaskHandle, "Dev1/ctr1", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 3.0, 4.0, 4.0);
DAQmxCreateCOPulseChanTime (gTaskHandle, "?????", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 7.0, 8.0, 8.0);
DAQmxCfgImplicitTiming (gTaskHandle, DAQmx_Val_FiniteSamps, 5);
DAQmxStartTask (gTaskHandle);
DAQmxWaitUntilTaskDone(gTaskHandle)
DAQmxErrChk DAQmxStopTask(gTaskHandle)
DAQmxErrChk DAQmxClearTask(gTaskHandle)
I believe this code should generate the 3 TTL square waveforms that I want for my application.
Please provide me with some feedback. It would greatly be appreciated.
Thank You

Hi,
The NI 6034E is a multifuntion DAQ device, this means you have:
(2) counters
(8) DIO lines (software timed)
(16) AI, single ended
(0) Analog Output
You have a couple choices here:
   1. Software timed digital output of all three signals, max 1khz loop rate, non-deterministic.
   2. Hardware timed digital output of 2 signals, max 20Mhz.
   3. Hardware timed digital output of 2 signals and software timed digital output of 1 signal.
   4. Find another NI MIO board such as the NI 6251. This board will do 10Mhz pattern generation for (8) DIO lines.
For the hardware connection, you are correct, the output for the counters will be taken from pin 2 & pin 40. Here's the pinout for the NI 6034E for reference:
The output of the Counters can be routed to some of the PFI's or to the RTSI connector. You can see this in MAX

I have an iPad 2 and recently purchased an iPad mini. My husband will take over the iPad2. How can he get an icloud account for this iPad (eliminating me) and his iPhone5?

Delete your iCloud account on the iPad 2, then he can follow the instructions to create his own iCloud account on it:

Then he can setup his own account on his iPhone.

Can I use the same drive to backup with Time Machine and Windows Backup?

I've got a 1TB external hard drive that I'm currently using for Time Machine backups and also it stores about 300GBs of music. Can I partition the drive to add an NTFS formatted partition and use that partition with Vista's Backup/Restore feature? If so, how do I partition the drive? Forgive me, I'm a neophyte when it comes to Windows. Also, I don't want to lose the music files already saved on the Time Machine partition.

While you can add HFS+ volumes to an existing drive, adding NTFS requires taking chances: change to FAT and then convert to NTFS.
I'd invest in another backup. I don't even rely 100% on any one backup method; drive; let alone TimeMachine. A bootable backup should also be part of your strategy for OS X. So I would create a smallish 40GB emergency boot volume - for OS X use only.
For Vista, I use the built-in features of Ultimate/Business AND Prosoft Engineering DataBackup PC. Norton Ghost started out okay but gradually deteriorated, though their 2009 360 2.0 or something....
I would not want to use WinClone except as one-time 'snap shot' or emergency; useful when moving to a new larger hard drive, and if your Vista partition is small and not 100GB of files.
I'd look at 500GB+ drive to use solely for Vista backup and media files.

I can't comment on foxnews. Same problem with IE, FF and Chrome.

I can't comment on foxnews. Same problem with all three browsers IE, FF and Chrome. The login does not appear on the right hand corner and the comment link does not appear on any article. I already checked to ensure cookies and 3rd party cookies were enabled. I've gone to DISQUS, but it won't let me login there either...doesn't recognize my ID or email addy. Suggestions?.

It appears they've shut down all commenting due to the troll antics on the site. The pornographic images they were posting and the racial attacks (among other things) when posing as conservatives may well have caused this. The Disqus filter wasn't effective in that it is easy to get around. Too bad as it was a great place to vent.

Dude or hot-spur,
Not fishy at all!!!! You really think I would have taken any more of my time to post a bogus rant? We'll no, it is unfortunately all true. I want to hear from anyone who is experiencing such problems not anyone else that wants to put there two cents in. I really don't need anymore hate or negativity. Just people's experiences because I feel like I am the only one having so many problems. Thank you
Yes, I have had some unfortunate bad luck to have so many problems at the same time, but some of them are just things you cannot do on the new OS.
Thank you again

I have 2 arrays with one same collumn
I want to show it on waveform chart with one x axis.
Its must lokks like that:

You can't have two separate Y axis stacked on one another. You can create multiple Ys that can be on the same side, or opposite sides.

Can a Servlet be used for Storing Objects with both JSP and JSF used on it?

Hi,
Pages I have:
SearchEmployee.jsp
This page has a search engine that search out the Employee. This Employee Object will be stored inside a Servlet(controller) for future references by other pages. I used JSP, html tags for forms, and request.getParameter() to built this search engine.
Problem:
I have a JSF Form that wants to DISPLAY the employee which I have found in my Search Engine. How can I get the JSF's value="#{Controller.employeeObj.name}" to get the value from the object?
This seems logical as my JSF form is just retrieving the stored object in the Controller. I currently cant seem to output it

The servlet shouldn't be used to store ANY data, let alone data to be accessed by other sevlets. Put the object into the Session object.
