• How to generate an impulse to test short circuit in an inducer

  Hello

  IM new to labview and am in need of complete SURG - SURGE STRESS TEST

  This test is intended to detect a short tour inter by applying a number of high
  voltage pulses (or surge) for the selected winding.
  Each pulse should produce one sinusoidal transient that eventually decreases to zero.

  How to generate the impulse using labview.

  Hi Jessica,.

  Please see the "pulse pattern.vi" function--> pallets of signal processing signal generation.

  Otherwise, you can browse through examples of LabVIEW.

• How to generate digital impulses to run the engine step by step in a sinusoidal motion using the NI DAQ 6229 map profile

  
  

  Hello

  I finally found a way to do it. The analog sine wave is converted to digital and sampled. The consecutive values are compared and if the least significant bit (LSB) will change a pulse is sent to the stepper motor to activate a single step.

  I've included the sub - VI who accomplish it for block engine and connector of particular Stairmaster I have. The front panel two sub - VI is quite messy, but the diagrams should be much clearer. The sub - VI get inputs from a third VI which I didn't understand. Then take a look at table VI of connector to understand. I hope this helps. A little messy but worked very well in the end of my application.

  Thanks again for all the help. I appreciate that very much.

• How do you define the amplitude of the pulse train?

  
  

  Of course, you can generate an analog waveform at some amplitude you want (in the range of what is supported by the Board of Directors), but the output of counter/timer is much more appropriate to generate a PWM signal.

• How to generate a pulse signal?

  Hello

  I'm relatively new to LabVIEW and I need to generate an impulse (Dirac function) in the motor continuous. At the same time, I need to be able to change the pulse width.

  I am currently using LabVIEW 7.1.

  Hey,.

  With your E-Series cards, you can counter to generate impulses for the user.

  The best way to find examples using the Finder example under the Help menu of LabVIEW. Simply navigate to the e/s material > DAQmx > Counter > generate signals or search for pulse generation.

• How to generate a field real-time tiara?

  Hello

  I tried a lot of things, but it is not working properly.

  I logfiles with the data of one ore more test ports. All entries in log file has a time stamp.  Timestamps are not equidistant. I can read the log file and get a table 1 d (n long elements) of the timestamps and a table 2D data (n x m elements m test ports).

  How to generate a report in the tiara with the time that x-axis it? The difficult is, I can't transfer the timescale to tiara.

  I could first convert timestamps double and double transfer al. This does not solve my problem. The tiara-channel resulting if of type 'float' and not 'time '. I need a script to swich the channel to 'time'. I see no solution to load a layout of report (TDR), to call a script to transfer data from additional text.

  Hello bohm,.

  When you write a channel timestamp in a PDM file, tiara automatically identifies it as a weather channel. So when you export the right data, you will get good results ;-).

  To illustrate this, I wrote an example VI: it creates two TDMS files with random timestamps and displays then the two files into a single report of DIAdem. I hope that you find it useful.

• How to generate a variable frequency pulse train constantly

  Hi all

  I am using NOR-USB-6259 (BNC) to send signals of impulse to the position of a servo with labview motor control. The position of the servo-motor control follows these rules:

  1. The pulse train number determines how many degrees the motor;(par exemple la position angulaire dele de moteur)
  2. The pulse frequency determines how fast the engine is running; (for example the engine rotation speed)
  3. Digital determines the direction of rotation of the engine (for example in the clockwise or counterclockwise)

  My question is when I have to continuously generate a body finished, train signal in a period of time. Here's a sample:

  Time (s)	Number of pulses	Direction of rotation (1 clockwise, counterclockwise 0)	Frequency
  0-1	923	1	923hz
  1-2	3540	0	3540hz
  2-3	1751	1	1751hz
  3-4	2663	0	2663hz
  4-5	353	0	353hz
  5-6	1017	1	1017hz
  6-7	3436	1	3436hz
  7-8	10 p	0	302hz
  8-9	1513	1	1513hz
  9-10	570	1	570hz

  Here is the explanation of this table, the motor continues to turn clockwise for 0 ~ 1s. When the time reaches 1 s, the engine simply fill out the rotation of 923 pulse signals. And then the engine starts to turn clockwise for 1 sec ~ 2 s. When the time reaches 2 s, the engine simply fill out the rotation of 3540 pulse signals. So we can see that the speed of rotation of the motor to 0 ~ 1 s is different from the speed in 1 ~ 2 s. Namely, the frequency of the signal from pulse to 0 ~ 1 s is different from the frequency in 1 ~ 2 s.

  I already use the DAQmx counter output, it can simply generate pulse signal with some numbers and some frequency only once. The attachment is the vi that allows to generate a digital pulse train finished the meter output channel and frequency, cyclical, delay report Initial and idle state are all configurable.

  How can I continuously generate a series of pulse train with a variable number and frequency for a certain period of time.

  Thank you very much for your help!

  The frequency 'on the fly' control requires intervention of software and can not guarantee a specific number of impulses for each rate (which I assume you want because it's an engine step by step).

  If it was me I would do one of them instead:

  1. use the digital output for everything.  The digital output at a higher clock rate and build the waveform to give you the desired number of steps and management.  This method would give less temporal resolution than others.

  2. use a task of meter output, 1 section at a time.  Reconfigure and restart the task for each section after the management output setting.  This method could introduce a delay between each section.

  3. purchase of new equipment - X series supports put buffered outputs of meter that can do what you ask.

• How to generate an xml file?

  I just starting to learn how to generate xml data with the actionscript here is what I have so far:

  var point: XML = < photo / >;
  DevBlog var = xml.photo.length () + 10001;
  Item.@name = photoIndex.toString () .substr (1);
  xml.appendChild (item);

• How XAI implements the 'do more' function in CC &amp; B pages

  Hi all
  There is a button "get more" in CC & B page if you put more than 50 recordings, just by clicking on the button when I want to get the latest recordings, but how do I implement the same function by XAI, I studied a lot of time on this problem and got nothing. so, everyone here had encounterd the same question? and resolved?
  any help would be appreciated.

  The GET more feature works in the browser because there is a separate servlet 'list' that retrievs data. It is based on some data to the HTTP context for correct operation. Unfortunately the 'do more' function is not supported by the Servlet XAI (it does not on the context HTTP data). Your only option is to roll your own mechnaism of paging for the data that you need.

  The model is going to like it...

  1. develop SQL code for what you want to paginate
  2. create a new "Listings Service" class that acts as a underlying service
  3 mark the service with entries include the size of the page and you want to retrieve the page number
  4. annotate the service with a list of data that will be returned
  5. use the page size and page number to create and run the query, and build the result
  6 enter the service as a Service of inbound XAI
  7. deploy the code
  8. test using dynamic presentation

  for example. Here is one more example for the search values...

  You need not repeat dozens of times or use profanity to get help.

  (1) disable all non-essential or unrecognized extensions on this tab. Don't know what it does? When in doubt, turn off:

  Firefox orange (or the Tools menu) button > addons > Extensions category

  Use the links above a disabled extension to restart Firefox if some seem to.

  (2) restore your Google search engine:

  https://addons.Mozilla.org/en-us/Firefox/addon/SearchReset/

  (3) check a user.js file (before the release of Firefox, otherwise the parameters in this file can cancel your cleaning) as described in this article: How to fix preferences that will not save.

  (4) If AVG search took over your page to the new tab (Ctrl + t), which changes as follows:

  (A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (B) in the filter box, type or paste newtab and make a pause so that the list is filtered

  (C) double-click the preference browser.newtab.url and enter the desired value for your favorite page:

  thumbnails (i) (default) Page = > subject: newtab

  (ii) blank tab = > subject: empty

  Firefox homepage integrated (iii) = > topic: welcome

  (iv) any other page = > full URL of the page

  IMPORTANT: If you have AVG software in your Windows Control Panel, you need to remove it.

• How to generate a high TTL and a weak pulse TTL using the USAB daq card

  Hi all

  I have usb daq 6361, how do I generate a TTL high and low pulse in labview to trigger my camera.

  Thank you

  Here is a code DAQmx to start your 6361, a digital output the value True (high TTL), wait a second, then set it to False (low TTL).  Have you tried to connect your device to your PC and pull them to the top of MAX?  He must "see" the device, and you can manipulate its ports to test.  Indeed, the name MAX gives your device is what you put into this first constant of e/s on my example (if you click the drop symbol, you should see a list of devices found as MAX).

• How to generate arbitrary waveforms FRO meter

  Hello

  I have a problem in the generation of the wave as shown in JPG below. Need to generate digital waveforms 2

  1. with the help of counter0 - digital waveform will be with pulse 60 (58 - good pulsations and 2 empty pulse)

  2. with the help of Freqout - digital waveforms should be to synchronize with a 40 pulse signal 2 signal should be high for then 5 impulses.

  I tried model digital generation with Boolean 2D table convert to digital waveforms. But somehow, I couldn't have expected waveform.

  If someone could help me in this problem.

  Thanks in advance

  Vijay

  FREQ Out is not able to generate either of two waveforms - it can only generate continuous pulse trains.  In fact, even one of the complete M-series meters would be unable to generate your "Signal 1" - you must use the 2nd meter to the signal from the door.

  Supported boards of series X buffered output of the counter and could therefore be used to generate a waveform.  You can use Freq Out yet, but the X series boards have also 4 full meters if this should be enough resources such as Freq Out is not necessary.
