Which daq card supports to perform fft operation on complex analog signal

i need to process complex analog waveform for radar based applications.i need a suitable daq card for doing that task.please specify suitable card and application notes to perform dsp based applications.

The answer to your question depends largely on the sample rate, resolution, and number of channels you want to have. The first place I would look is the M Series devices at http://www.ni.com/dataacquisition/mseries.htm. Using LabVIEW, these analog input devices can read in a signal and easily perform an FFT on it.

An AC signal is nothing more than a constantly changing DC voltage. Ok, there's more to it than that. But still, the DAQ takes quick snapshots of what the signal voltage is at a given instant. If you take enough of these snapshots, you can recreate the signal. Niquist states that you need to sample at at least twice the bandwidth of your AC signal. I recommend more of 3-5 times.

Which MSI card supports the apple 30"

There are so many video cards out there and theories about which card will run this monitor, i almost wasted a lot of money trying to run the monitor on my 6800GT... it doenst i have tried both DVI ports.
Basically i want to know which MSI card supports the apple 30" does the new 7800? the old 6800 ultra? is my 6800GT messed?
A few things i can confirm are this, the monitor because of some signal issues DOES NOT support SLI at all.
I have read a few reviews that say the 7800GTX does not support this monitor - very disappointing i have to look for an older 6800 card.... - this is unconfirmed maybe someone can get back to me about this.
Anyways if MSI could tell us which card of theirs works i will turf my 6800GT and buy whatever is needed.

I can't be shure which MSI card support it, but reading the release notes from the latest nvidia drivers (77.22) I saw this:
The GeForce 6800 Ultra 512MB works in single card mode with Apple 30 inch HD Cinema panel. However, an issue has been discovered when running the GeForce 6800 Ultra 512MB card in SLI mode with an Apple 30 inch HD Cinema display. This is due to an interaction
between the GPU, the application, and the ability to scale to nonnative panel resolutions of the Apple display.
All GeForce 6 series GPUs will work with Apple 23 and 20 inch HD Cinema displays in single GPU mode. NVIDIA recommends using the GeForce 6800 Ultra 512MB with the Apple 30 inch HD Cinema Display line only in non-SLI modes.
Edit here:
Modes Supported for High Resolution Displays:
Display:
*Apple 30” Cinema HD Display (Dual link DVI)
Hardware Requirements:
*All High-end Quadro FX (see list of products in “Quadro FX Family of High End GPUs”
* GeForce 6800 with 512 MB
Maximum Resolution:
2560x1600 @ 60Hz
Source: 77.22 Forceware Release Notes.
I guess that your card (6800 GT Non Ultra) doesn't support it. Maybe a new drievers release will fix this.

Why we cannot perform DML operations against complex views directly.

hi
can any tell me why we cannot perform DML operations against complex views directly.

Hi,
It is not easy to perform DML operations on complex views which involve more than one table as said by vissu. The reason being you may not know which columns to be updated/inserted/deleted on the base tables of the views. If it is a simple view containing a single table it is as simple as performing actions on the table.

Which tool is support Discoverer performance/load testing

Hi,
Any one can tell me which tool is supporting the oracle discoverer for olap 10.1.2.48 performance / load testing.
We are using one of the third party tool called QALOAD. We are unable to trace the discoverer session.
We wanna perform 50 concurrent users peformance test.
is oracle is recommending any tool for performance on the discoverer for olap 10.1.2.48??.
or any one can tell me based on your experience which tool is supporting/best tool to test.
thanks,
Nats!!!

Did you get an answer to your question. We are now trying to use Load Runner rmi calls and have difficulties.
Please provide any information you have on this matter.
Thanks.

Which DAQ card can give accurate specified sampling rate

Dear friends:
I have an application to sample the data from an analogue device with user specified sampling rate, e.g.171KHz. May I know which NI DAQ card can specify any sampling rate below 200KHz within tolerance of inaccuracy of 1KHz? Appreciate for your help
Andy

Do you need both accuracy *and* precision?
Precision will largely be determined by quantization effects as the sample clock must be an integer divisor of the board's master timebase. For example, the 6259 M-series board that I commonly use has an 80 MHz master timebase which can be used to generate the sample clock. In fact, I'm pretty sure it *is* used by default.   The nearest integer divisor when requesting 171 kHz will be 468, producing an actual nominal sample rate of 170.9402... kHz.  (A divisor of 467 would produce a nominal sample rate of 171.3062...)     The quantization doesn't really scale linearly over wide ranges of target sample rate, but for rates in the vicinity of 171 kHz, quantization steps are a bit less than 0.4 kHz, so you can expect to hit your target to within about +/- 0.2 kHz.
Next you need to consider clock accuracy. The 6259 board is rated at 50 parts per million accuracy at nominal temperature of 25 C. I don't know the temperature effect or whether you need to concern yourself with it in your app. But 50 parts per million on a target of 171 kHz amounts to less than 0.01 kHz accuracy error.
So it would appear that the 6259 would be a candidate. There are likely other cheaper M-series boards that could also work. The older E-series had only a 20 MHz timebase, which would lead to quantization error of about 1.5 kHz. Don't recall their accuracy specs, but quantization already puts you over your error budget.

I would like to know: what sort of DAQ card, I have to use with LabWindows, to have datas from 3 sensors?

If you have some references or internet sites, please, answer me.
A French guy.

Most any of National Instrument's DAQ boards will do this. We provide a tool to help you pick which DAQ card is best for your application called DAQ Designer. You can access DAQ Designer online at: http://www.ni.com/daq/ddonline.htm.

For Agilent LCR Meter (E4980), which DAQ can be used for pc interfacing?

hi, I have Agilent LCR Meter (E4980), I would like to interface with pc by using LabView program. My problem is how to use it and which DAQ card/system suitable for interfacing. Please advice. Thanks.

My suggestion is that you do some research in Instrument Control. You certainly do no want to use a DAQ card for this. The Instrument Manual chapter 8 gives you your options for control. There is a LabVIEW driver located here.
Using LabVIEW 2010SP1 and TestStand 4.5

Are there compatibility issues with using labview 4.0.1 with a DAQCARD 6024E. Which Ni-daq version should I use? Operating system?

I recently purchased a DAQCard 6024E and am trying to set it up on a windows XP laptop. Labview 4.0.1 vis do not seem to function. Do I have some compatibility issues? Thanks

Hello;
The oldest version of NI-DAQ that supports that card of yours is 6.6, which doesn't support Labview 4. Furthermore, the only NI-DAQ version that supports windows XP is the latest one, 6.9.2, and the Labview version that supports that same OS is 6.1.
Since you will have to upgrade Labview to be able to work with that DAQ card of yours, I advise you to upgrade to Labview 6.1, so you can work under XP also.
Hope this helps.

Which intel cards DO support vaapi?

I'm not sure if multimedia is the right section and not hardware...
I tried to find something about which intel graphic cards support vaapi and the information i found is not very good.
Something like "G45 or newer" does not really help me...
I have an eee 1000h with intel 945GME running with the i915 driver. I think I cannot use libvaa there.
Some websites say you need poulsbo = GMA 500 (whatever this chip is) or i965?
As I am not very familiar with intels chips this does not really help me:
http://www.freedesktop.org/wiki/Software/vaapi
It says "Intel Embedded Graphics Drivers (IEGD)" and this includes support for "Mobile Intel® 945GSE and 945GME Express chipsets" which is my card I think.
Is this included in the i915 or do I need something in addition to this driver or do i need to replace it or am I just misunderstanding what it is saying?
Can someone clear it for me? Maybe with a list of supported cards?

Intel doesn't want to publish the information because of the massive overhaul that they've been doing in their driver model. In short, it's not ready. Freedesktop's Intel implementation is by Intel itself, so they'll only publish what Intel publishes.
The GMA 500 (Poulsbo) is a piece of crap on Linux right now. The most stable driver with any kind of acceptable performance is uvesafb, which has no 3D, hardware decoding support, or color management of any kind. There is no stable driver for this platform for Linux (or even Windows the last time that I checked).
The problem with all of this for desktop users is that desktop Linux is not a priority for Intel. If they have even four developers working full time on the entire Linux stack with desktop use in mind I'd be surprised.
And, to complicate this a little more, uvesafb doesn't work with the latest stable kernel at the time of this post (2.6.34)...
http://bugs.archlinux.org/task/19645
so, if you haven't already bought a netbook wich comes with the poulsbo chipset (i envy you), my recommendation is: don't do that, at least for now, because poulsbo support under linux is _very_ uncertain ATM.

How to monitor DAQ card outputs during TestStand operation?

I am trying to debug a rare failure mode on a test station that runs on TestStand. TestStand controls measurement equipment through a PCI-GPIB controller and a DUT and DUT switch box through two NI-DAQmx devices; PCI-6509, and PCI-6534. I believe that root cause of the failure is due to the software not putting the DUT into the correct state for the test. In order to check this I need to monitor the changes on the GPIB and DAQ cards. I was able to use NI Spy to monitor the commands on the GPIB bus but I have not been able to monitor the state of DAQ cards. Is there a tool that will allow me to pause TestStand during its operation and look at what logic states the PCI-6509 and PCI-6534 outputs are in? Or at least monitor the I/O of the PCI-6509 and PCI-6534 cards similar to what NI SPY offers for the GPIB cards?
Regards,
David

I am not aware of a tool similar to NI SPY for I/O cards.
However you can introduce a break point at the point of interest in a test sequence(step).TestStand will stop execution at that point.
You can then manually verify the I/O status using a DMM .
Hope this helps.

Which type of ADC is used in M Series, S Series and C Series DAQ Cards?

Hi
I want to know which type of Analog to digital converters(ADC) are used in M Series and S Series DAQ Cards. I know that DSA Cards and some C series are using Delta Sigma ADC. What about the ADC used in non delta sigma C Series modules. Why Delta sigma ADC is not used in M series and S series DAQ cards.
Regards
Samuel J

Hi Samuel.
The ADC type used is Succesive Approximation ADC. You can refer to the following links for your reference.

My pc has win the operating system view, which does not support lightroom 5. I want to buy version 4?

Thank you, Jim, for your prompt reply. Amazon has it for $151.99, Ebay has a few copies that end up being about as expensive after international shipping and other fees, and I don't trust most of the other sites after reading reviews on them. Looks like I'm going to have to fork out some dollars. How unfortunate.
Thanks again,

Which cards support AS

Hi,
I'm in the process of specifying some computers that will be in a music technology classroom (school). There is an intention to use Cubase and Sibelius with these machines. Having experienced latency issues in the past, I believe I need a card which supports ASIO? Is there a comparison table which shows which cards support ASIO? Does the Audigy SE? There's no mention of it on the spec page, but wanted to check. Thanks

SE don't support ASIO.
In generally, all Audigy 2/4 models (excluding Audigy 2 NX) and X-Fi models (excluding XtremeAudio) supports ASIO. Also there normally is mentioned if card supports ASIO in product pages.
Li've! series cards don't support ASIO nati'vely but there are 3rd party drivers which can be used w/ Audigy 2 NX @ Li've! 24-bit External;
