NI9401 output signal

Hi,
I am currently uisng the CDAQ 9178 and the NI 9401 modules to generate the output signal. Currently I am testing out using the
Generate Finite Digital Pulse Train Retriggerable.vi from the NI example finder. The main problem i am facing is the I can generate a pulse but is unable to vary the frequency on the go. Meaning to say, whatever value i set initially will be taken as the fixed value in generating the pulse frequency. May I know what are the ways to generate an digital output pulse signal that has varying frequencies? up to around 100kHz?
Hope someone could help me thanks a lot
Jhao

Hi,
What is the model of your machine ? Your AIO computer is design as stand alone AIO machine. If you wish to connect it to a TV, you can use an external video card such as one of these:

How to create 2 output signal locked in phase from a one input signal

Hi all,
I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be around 120 hz and 150 hz .
I am using USB - 6003 daq card.
I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase as the input signal. I have seen a PLL vi , but dont know how to use that with my program.
can any one tell me how to proceed.
thanks

Hi AnkitG,
Here are a couple of links that might help you understand a little more how the PLL work and a way to synchronize the task to perform a PLL.

Also, you should be able to find a lot of examples on how to accomplish the synchronization of tasks on the community, if you consider that the only consideration is that both must start at the same moment.
I hope, these examples might show you some useful concepts:

Output signal high at DIO lines of 7330

Hi
I am using Labview 7.1 with Ni motion controller. I am trying to detect the output signals at the auxiliary DIOports of the card using the attached programme in the NI example finder. My board ID is 1 (thats what was allowed by the programme) and I put port 1 , to check the DIO lines of it. I checked pin 10 (port 1-bit 0) and pin 44 (port1-bit 1) using an oscilloscope. The output is high at 5volts.
I changed the DIO pin polarity switches to active low status but the output remains the same.I fiddled with the set and reset buttons of the programme, initialize the card but nothing changes. Any idea on how to figure whats wrong?
Thanks

Auxilliary Digital Output.vi ‏57 KB

Hi
Thanks for the reply. Sorry for the delay in response as I was on vacation. I tried your programme but the result remains the same. The output is always high.
Max shows the card is working properly. It also shows the board type as 63. But the programme only takes in board ID as 1. How can set the direction using MAX and save the settings?
I tried the write 1 point example programme on axis 1 ,line 1 and tested the signal on pin 44 and 42 (oscilloscope ground), and toggled the line but the output is high. But when I stopped the programme with the STOP button it gave an error message 70102 with a possible cause the setting doesn't match the line direction?
The oscilloscope ground was firmly connected to pin 43 or 42 of the board for all tests.
I appreciate your help.
Thanks

Unsupported output signal for Sony Bravia KLV-32T550A

I have a mac mini 2007 running 10.6.3. I am trying to connect to a sony bravia KLV-32T550A either through VGA or DVI. Both keep coming up with error message (unsupported output signal, adjust your pc signal)
I have updated setting on the TV as per some forums I have read so am sure its not the TV.
Now the TV says the native resolution is 1366 x 768 but there is no exact match in display settings. Could this be the problems.
I have read that i can download switchresx and this should fix the problem.
Can anyone shed any light on this it would be much appreciated>
Thanks

Definitely the second computer can be a big help. If you set up Screen Sharing between the two so that the mini's screen is shared over to the MacBook, you will be able to see the mini's screen on the MacBook even though the display connected to the mini is dark. And from the MacBook you will even be able to control the mini, so you can go into Displays Preferences on the mini and make alternate selections for resolution and, if necessary, refresh rate. Hopefully you will hit on a combination that will light up the mini's attached display.

Change form of output signal without initializing new process of output signal

Hello!
How to change form of output signal produced on the output channel without initializing new process of output signal?
Thanks
Message Edited by _Pavel_ on 10-28-2009 05:21 PM
Solved!
Go to Solution.

I'm working with LabView 8.5.1.
I have periodic TTL impulse with constant frequency – signal to start , which I'm used to start data acquisition (PCI-6251)and generation signal (PCI-6221).
When TTL signal a detection, necessary generation some analog signal (PCI-6221) and acquisition other analog signal (PCI-6251). Then wait following TTL signal.
At this moment I write the part of the program which is responsible for data acquisition. Function retriggering (In examples C:\ProgramFiles\National Instruments\LabVIEW8.5\examples\DAQmx\Synchronization\Multi-Function.llb\Multi-Function-CtrRetrigg Pulse Train Generation for AI Sample Clock.vi) is used. This function necessary,because we start data acquisition each time on arrival TTL impulse, andrepeated creation of the virtual channel of data acquisition with the newtrigger spend a lot of time.
The problem consists in the following. Generation of the data from other card should occur on the same impulse TTL as for the data acquisition card and then generation zero value.
How I can realize it? I planned to change the form of an impulse of generation when detected TTL an impulse, without reinitialize process.

Output signal distorted

I have a pretty large VI which outputs high frequency signals to control some hardware and then takes an input from that hardware for image rendering. My problem is that whenever I activate the imaging portion of my VI, the output signals become slightly distorted. For example, a 1Hz sawtooth output doesn't ramp up smoothly but becomes slightly staggered. This also messes up the frequency of the signal. Does LabVIEW have problems outputting signals properly when another portion of the VI has a lot of cpu intensive processing?
I am using the "Simulate Signal" block to create a 1 Hz sawtooth wave, 128 Hz triangle wave, and a 65,536 Hz square wave and outputting these signals through DAQAssist.

Hi Laura,
I went ahead and changed the 65,536 Hz square wave signal as the first input, but the three signals still do not output simultaneously. Although the signals slightly change as I vary the Samples per Buffer and Cycles per Buffer, I can't seem to get a combination that is capable of outputting these two low frequency signals with my high frequency signal. I would either get an error message about "DAC conversion attempted before data to be converted was available," or there would be no error message but the signal output didn't match the given specifications. Attached is the vi with the modifications. Presently, there is no error message with the given sampling information, however there is no square wave output at all, and the sawtooth waveform only shows a partial amount of the signal. I had to make some slight modifications to the Waveform Buffer Generation vi in order to allow me to change phase, duty cycle, and offset of my square wave. I don't think this would have any effect on the Cont Gen Voltage Wfm vi though. Any ideas what's going on?
Thanks a bunch,
Anthony

Gateway In problem (Wroung output signals)

Hi,
I build a FPGA circuit to test.
The source come from a normal simulink block “Pulse Generator”.
After the signal go through the block "Gateway In", the output signal of the ""Gateway In" is wrong.
Is there some one can give me some advice ? Thank you.

The problem is your sample period on the gateway in block. It's only taking in one sample every second but your pulse is going much faster. And your simulation only runs for 0.001 seconds. So you're basically seeing the output of 1 sample.

What is the effect of output signal with the same sampling frequency but different number of samples?

Hi,
I'm using PXI4461 for audio measurement and there is a question about analog output. I'm using the Basic Multitone vi for generating multitone signal. The sampling rate is 200k and my question is how to determine the number of samples. I used an audio analyzer to measure the distortion of the output signal with 200k and 1k points and there are no different except the update rate. What number of samples is suitable for 200k sampling rate?
Thanks,
Bill

The Sampling Rate determines the maximum frequency that you can see (the rate/2 according to Nyquist).
The number of samples divided by the rate determines how long you will sample. This sample time can only be determined by you. Do you need .1 seconds worth of data, or 1 second? But note that the MINIMUM frequency that you can detect is 1/(Sample Time) or the Sampling Rate/Number of Samples. So if your system has a minimum and maximum frequency specification use that as your guild.

Dynamic output signal control

hi
i am using a PCI-6259 card with Measurement Studio 2003 and NIDAQ 7.4
I am trying to change an analog output signal on the fly, e.g. using a slider.
My first attempt was using the 'WriteMultiSampleAsync' -function and installing an eventhandler.
So when i put my write-function into the 'OnEvent'-function of my event handler i get an error
message telling me that i got too less memory. Anyone has an idea how i can solve this problem?
I think i'll have to use multiple buffers, but am not sure how this exactly works.
Thx
Markus

Hello Markus,
the examples that are installed with Measurement Studio which should be enough to give you an idea how to create such an application. If you are looking for a way to change an analog output with a slider, it is actually pretty easy. As log as you dont want to do a waveform output you dont need buffering at all.
If you write a value to an analog output, this voltage will stay there until you write a new value or the PC is powered down. That is why it is enough to work with single point AO in this application.
Pleas have a look at the "AO Point example". It will show you the principle.

Starting triangular output signal

Greetings,
I made this VI, but there's an error in it and I don't think it's solvable like this.
The triangular output signal should start when I press the boolean. Else the DAQ Assistant should put out 0V.
Also when I press the stop button the DAQ Assistant has to put out 0V
Is there another solution?
Thanks
Solved!

I recently made a solution by using the "Select" function.
The Triangle Pattern produces the pattern I want the DAQ Assistant to send out the Output Signal.
I'm using a USB 6008.
But now I have a different issue. When I press the Start button, there's a sudden high pulse of 1V and then the output continues the regular Triangle Pattern.

15454 Low Output Signal Power

Having a problem with the Bits timing output on pins A3, B3 and A1,B1 on the back of the Sonnet Shelf. Appears the output signal power of our 15454 is reading 1.30 which is very low.
Tried changing the LBO setting and it did not make a difference.
Need to now if there is a way to boost the signal power level up.
The bits timing ouputs are used to time our Motorola BSR (CMTS) for telephony. The problem the Motorola BSR's are experiencing is when you failover the SRM (CPU) to the Secondary SRM, you loose both timing inputs.
Any advice?

Changine the output signal on a pressure transucer

Im trying to change a pressure transducer's Output signal from 0-5V to 0-10V. Where would I find this setting under Measurement and Automation Explorer?

You can't change the range of your pressure transducer from within MAX. That is set by whoever manufactured the pressure transducer. If you want to change the input range of the compact Fieldpoint module that it is connected to, you can do that within MAX. What analog fieldpoint module are you using?
Browse to the specific module you want to change within MAX. Right click and pick Go to Device configuration. Pick the Channel configuration tab. There you will be able to set the input range for each channel.

Connet industrial output signal to CB-68LP

I have a problem to connect industrial output signal(1-5VDC) to CB-68LP.
Please help me as soon as possible.

Hello;
You need to provide more information than you did so we can help you better.
The CB-68LP is a connector block only which will follow the features of the DAQ board that is connected to it, as far as number of channels, sample rate, pinout, etc.
Please, be more specific on what sort of problems you are seeing there.

Output signal has a short halt.

I developed a measurement system with S&V toolkits. I am sending a Gaussian signal to the D/A output which then goes to our loudspeaker as a white noise signal. In the meanwhile, I record two input signals to do FRF averaging analysis. I can hear the signal "cycle" every two seconds or so.
Does the input averaging operation cause the problem for the output signal in S&V Vis?
Thanks a lot for any responses

Hello,
If I understand your application correctly, you are generating a Gaussian white noise signal which you output to a speaker. You have a process running in parallel that inputs two sound signals and then analyzes these input signals. If I have misunderstood you, then please correct me.
From your explanation I am not clear on the exact problem. Is the problem that you are seeing a small pause in the output signal, which you believe may be attributed to the processing that you are doing on the inputs? Or, is the problem that the noise output signal seems to repeat itself once every two seconds or so?
If you are concerned that the FRF analysis is interfering with your I/O, could you possibly wait until after the data collection is complete to perform the analysis, rather than doing it on the fly? If the problem is that the output signal is repeating itself, please explain to me how you have programmed the output (perhaps you could attach a screenshot of the part of your code that does the output).
With a little more information about the problem I should be able to provide you with better answers. Thanks!
