How can I measure the phase difference of two input signal?

Hello,
I'm trying to measure the phase difference of two input sine waves with the
same frequency.
Is there anybody how I can do this with labview?
Thanks,
Dae-han

This is my case! I have TDS3034 which can measure phase. However when I open Read Waveform Measurement vi that comes with tkds30xx.llb, I have a number of options under "measurement function" but not the phase measurement. May be I need another vi to do this?

  • How can I measure the time difference between spikes (interspik​e intervals)

    I have used NI USB-6008 (DAQ) to sample a continous signal, after sampling I compared the amplitude of the resulted signal with a value. If the amplitude is greater than a specific value (threshold) then it can pass. Now I want to measure the time difference between the resulted samples. The samples look like spikes. (May be if I trigger a timer, then I can measuer the time difference, but I have not seen such a timer). 
    Thanks in advance,
    Saraydin

    Oops just occured to me that you are using a 6009 which is not very fast, 48ks/sec, this will not get you very much time resolution and you could have issues seeing much of a 50 us sample.  Another approach is to use the counter but you would have to preprocess the spikes to generate a trigger for the counter.

  • How can I measure the time between each two successive rising edges ,using Digital Input ?

    Hello
    I'm trying two measure the time in seconds between each two successive rising edges on a digital input .
    Till now I have managed to detect the rising edge ,increment a counter with each rising edge ,and snap the time at which the rising edge happenned
    all I need now is to subtract the current rising edge time from the previous rising edge time in order to calculate (T) which can be 1/frequency and display it in realtime to the user.
    but I don't know how to do this
    Can somebody please help me !!!

    Counter without time.vi ‏11 KB

    Woah!  
    Sorry Apok, but your code is becoming way too complicated/messy. I don't think that all of those shift registers or boolean conversion/operators are needed at all.
    If you want to measure the timing between two button presses then this is a different (much less complicated) way. It simply records the timing of the button press into a shift register then compares the two.
    Spoiler (Highlight to read)
    Of course this is a very quick and basic solution just to show you that it can be much simpler than you are making it (remember to use the mechanical actions of the buttons to get the behaviour you want).
    A better way would be to use an event structure looking at value changes of the buttons to determine the timings between clicks.

  • How to calculate the phase difference between two square wave (acquired from two channel in one DAQ)

    Hello everyone ,
     I need a quickly help that as below :
    I am trying use PCI-6220 to acquired six signals from one rotation encoder (channel A, channel B,channel Z ,and their non-signals) .The encoder out signals will be square wave and 4000pulses per revolution. I set it rotation at 300rpm speed. I need show every square wave of six out channels in waveform and measure the A-B phase difference to check if the value is correct (designed value should be 90deg) .
    I have no idea how to measure or calculate the phase difference of two square wave base on synchronizate to acquire these two square wave from two channel on the PCI-6620....
    Anyone can give a idea how to calculate the phase difference with two square wave ?
    Thank a lot and Thanks again...

  • How to find the phase difference between two signals using Hilbert transform

    hi, 
        I am new to LabView.... I am trying to find phase difference between two signals. I sucessfuly found out the phase difference between two predefined waves using single tone measurement. .... But I really want to know how can I measure phase difference between two signals( not predefined... ie we don't know the initial conditions) using hilbert transform or any transformation techniques (without using zero cross detection).. I tried by using hilbert transform based on algorithm... bt I am getting error.... plz help me

    you could try something similar to this, for each table pair that you want to compare:
    SELECT 'TABLE_A has these columns that are not in TABLE_B', DIFF.*
      FROM (
            SELECT  COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
          ) DIFF
    UNION
    SELECT 'TABLE_B has these columns that are not in TABLE_A', DIFF.*
      FROM (
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
          ) DIFF;that's assuming, column_name, data_type and data_length are all you want to compare on.

  • How can I measure the hertz in a wave form?

    How can I measure the hertz in a wave form?

    As an example, this is from BBC Technical Requirements for HD material:
    3.1.1 Stereo line-up tones
    All stereo tracks must use EBU 1KHz tone (left ident). All tones must be sinusoidal, free of distortion and phase coherent between channels.
    Digital Audio Reference level is defined as 18dB below the maximum coding value (-18dBFS) as per EBU recommended practice R68.
    See also:
    http://www.bbc.co.uk/guidelines/dq/pdf/tv/tv_delivery_to_network_programmes_v1.2-2011.pdf
    for full document.
    And for BBC Radio:
    Not every Network requires tone. Check the delivery requirements with the commissioning network or click here.
    Reference tone, where used, should be at -18dBFS or PPM 4 on A, B and/or M.
    If submitting material with reference tone, tone and programme material must be have been monitored and measured through the same technical chain. The level of the tone must be equivalent to 0dBu and no less than 8dB below peak audio level for the programme material.
    THE LEVEL OF TONE MUST HAVE A KNOWN RELATIONSHIP WITH THE LEVEL OF THE PROGRAMME MATERIAL AND THIS MUST BE STATED; for example: “Tone at 8dB below peak programme level”.
    As a newcomer to digital sound (my background is camera) I confess to being somewhat confused. We are normally told to record at the highest level possible. So for voice podcasts I tend to record at about -6dB below peak for maximum volume, distributeds on MP3 files.
    But I can underatand that televison and radio especially for analogue transmission) may have limited headroom, hence the requirement for -18dB peak = 0dBM.
    I remember when we first rented out Digital Betacam cameras, some recordists were recording almost everything OVER -18dBM.
    I suspect that until we have an all-digital world, these requiremnents will still be in place.
    Many thanks to all. It's a ghreat community!

  • How can I measure the Graphics Card usage? I.e. percent load

    Hello,
    How can I measure the Graphics Card usage, like with the processor in Task Manager, but instead giving a percentage usage for the graphics card instead? Is there an easy way to do this, or would it require a lot of code? Is it even possible?

    Ah, so It's unlikely that Java3D will include anything for reading this data then? I was really aiming at measuring the GPU usage under this API which although i have limited knowledge using, I do at least have some knowledge - I wouldn't have a clue how to access any other API's!
    I'm using an NVidia TNT2 card at the moment, which is quite old.

  • How can i measure the speed of the fan in sound and vibration signal simulator box

    how can i measure the speed of the fan in sound and vibration signal simulator box
    provided the values  tach out:2 pulses/revolution and  maximum speed = 6000rpm

    Hi. I tried your suggestion and I could not get it to work well. In
    fact it worked better without the running average (which suprised me).
    I also played with the number of data points but still could not get it
    to work well.
    Do you have any other suggestions on how I could sort this problem out?
    I
    have attached a screen shot of the signal. To recap, I'm trying to
    measure the'y' position of the flat regions of the signal. The signal
    does not have a constant level, so this 'y' position varies with time
    in a non-unform manner.
    I am currently differentiating
    the signal and selecting the y position when the differential is equal
    to zero (within a tolerance band).
    In the screenshot, the
    signal has been zeroed using the method I have described above.
    However, it occasionally has glitches which may be caused when the code
    picks up a zero gradient at a peak or valley in the signal.
    I therefore need some kind of algorithm that only measures the position of the flat regions.
    Many thanks

  • How can I measure a 0% or 100% duty cycle signal ?

    I want to measure the duty cycle of an input signal using a counter of a 6030-E board.
    I work with a PXI Rack under Labwindows/CVI.
    My program already works properly for duty cycle between 1% and 99%, but it is not able to detect 0% duty cycle (ie : signal to ground), nor 100% duty cycle (ie : signal to power supply).
    The problem is I don't understand how the counter works in such a situation (it cannot detect any edge, as long as the signal is continuous 0V or continuous 12V).
    Please have a look on the following code :
    1- First, the counter is configured
    // Reset Compteur
    i_Status = GPCTR_Control(iDevice, iCptID, ND_RESET);
    //Definition du type de mesure du compteur (mesure temps impulsion)
    i_Status = GPCTR_Set_Application (iDevice, iCptID, ND_SIMPLE_PULSE_WIDTH_MSR);
    //Definition de la vitesse d'echantillonage (20 Mhz)
    i_Status = GPCTR_Change_Parameter(iDevice, iCptID, ND_SOURCE, ND_INTERNAL_20_MHZ);
    //Definition du signal a mesurer (defaut)
    i_Status = GPCTR_Change_Parameter (iDevice, iCptID, ND_GATE, ND_DEFAULT_PFI_LINE);
    // initialisation du compteur
    i_Status = GPCTR_Change_Parameter(iDevice, iCptID, ND_INITIAL_COUNT, 0);
    // Preparation du compteur avant de l'armer
    i_Status = GPCTR_Control (iDevice, iCptID, ND_PREPARE);
    2- Then, every 10 ms, the value of the counter is read, so that I can calculate the duty cycle...
    i_Status = GPCTR_Watch(iDevice, iCptID, ND_COUNT, ul_val_cpt);
    3- ...and the counter is armed again for the next reading
    i_Status = GPCTR_Control(iDevice, iCptID, ND_ARM);
    When duty cycle changes from x% to 0% or 100%, the counter always keep the value corresponding to x%.
    Even if I reset the counter between each measurement, it keeps this value ! I don't understand how it is possible.
    How can I know that the counter didn't see any edge, and so that duty cycle is 0% or 100% ?
    Thank you in advance for your help !

  • How can I get the selected rows from two ALV grids at the same time?

    I have a program that uses two ALV grids in one dialog screen. I'm using the OO ALV model (SALV* classes).
    The user can select any number of rows from each grid. Then, when a toolbar pushbutton is pressed, I'd have to retrieve the selected rows from both grids and start some processing with these rows.
    It is no problem to assign event handlers to both grids, and use the CL_SALV_TABLE->GET_SELECTIONS and CL_SALV_SELECTIONS->GET_SELECTED_ROWS methods to find out which rows were marked by the user. Trouble is, this only works when I raise an event in each grid separately, for instance via an own function that I added to the grid's toolbar. So, I can only see the selected rows of the same grid where such an event was raised.
    If I try to do this in the PBO of the dialog screen (that contains the two grids), the result of CL_SALV_SELECTIONS->GET_SELECTED_ROWS will be empty, as the program does not recognize the marked entries in the grids. Also, an event for grid1 does not see the selected rows from grid2 either.
    As it is right now, I can have an own button in both grid's toolbar, select the rows, click on the extra button in each grid (this will tell me what entries were selected per grid). Then, I'd have to click on a third button (the one in the dialog screen's toolbar), and process the selected rows from both grids.
    How can I select the rows, then click on just one button, and process the marked entries from both grids?
    Is it somehow possible to raise an event belonging to each grid programmatically, so that then the corresponding CL_SALV_SELECTIONS->GET_SELECTED_ROWS will work?
    Thanks.

    Hello Tamas ,
    If I try to do this in the PBO of the dialog screen (that contains the two grids), the result of CL_SALV_SELECTIONS->GET_SELECTED_ROWS will be empty, as the program does not recognize the marked entries in the grids. Also, an event for grid1 does not see the selected rows from grid2 either.--->
    is it possible to  have a check box in each grid  & get the selected lines in PAI of the screen ?

  • How can I measure the frequencies of two analog input signals simultaneously?

    Hi
    I have two AI signals, and I need to determine the frequencies of those signals. The frequencies range from 1-125Hz. I currently have a VI where I can sample one of the signals for 1 second (sampling at 300 Hz for 300 samples) and determine the frequency. 
    I need to read two signals at the same time and get both of the frequencies at the same time, but I can only figure out how to read them individually, so I can read one signal, then one second later I read the second one, then I read the first one again, then the sceond one, etc..  How can I read two signals simultaneously?
    Thanks

    "at same time", this depends on the hardware, you can do as has been previously stated just set up a 2 channel acquisition and you will get 2 sampled waveforms back.  Most hardware A/D as multiplexed and true simultaneous sampling is not done.  At 125Hz this is not an issue unless you are interested in very small phase changes between the samples.  just keep this in mind if you are expecting samples to be completly synchronized.
