• Acceleration in the frequency domain

  Hello

  I enclose a vi that I already modified the existing example. I will use this vi to measure pressures (pressure sensor) and acceleration (from an IEPE accelerometer). Each of the two sensors is connected to a housed in a chassis CompactDAQ C Series module connector 4. The pressure sensor measures the pressure of the water flowing in a pipe while the accelerometer will simultaneously measure the vibration of this pipeline caused by the fluctuation of water pressure. In this vi, I am connecting a signal of pressure and acceleration TDMS file and then read the two signals on the cards of distinct waveform. The acceleration signal is written and read in the time domain. I need your help to make change more on this vi to take the acceleration signal and read on a separate table in the field frequency and written also the frequency of the field values in a file of PDM. After this change, the vi is supposed to have three graphics of waveform (pressure, acceleration time-domain and acceleration in the frequency domain and opens two tdms files, one for pressure and acceleration in the time domain and one for acceleration in frequency domain.)

  I tried many ways all failed because I'm not very familiar with the measurements of vibrations.

  I thank in advance.

  Hello

  It is important that you should decide if the frequency data you are interested in are constants based on time, or if you need to know how the data of frequency changes over time.

  For constant frequency over time, take a look at the Fast Fourier Transform: http://www.ni.com/white-paper/4541/en/

  If you need to know how the frequency display, take a look at the analysis of the frequency of the common time: http://www.ni.com/white-paper/3548/en/

• How to detect the peak frequencies in the frequency domain?

  Hello

  I built a small test consisting of two sine waves of varying frequencies, program it is and subsequently FFT is performed on it to find the frequencies of two peaks. I tried to display the values of these two frequencies somehow, but I can't find a way.

  I searched the forum before asking the question, many of them suggested using extract more Information VI tone I tried and could not get any results.

  I have attached to my account. Please take a look. If you know all the discussions on the forum directly related to my problem, please just cite it.

  Thank you

  Don't wire the tone of several extracts the wire coming from the Express VI of Sprectral.  You need to run on the thread after that the two signals are summed.

  Hi Harsha,

  As you use the "tree" in the em console to test your service, it does not correctly recognize extensions/restrictions 'simpleContent '.

  I suggest that you use the 'XML' view, but if the attribute is missing then you must add it manually to the. ( Ex: ) .

  I suggest that allows you to test your service SOAP UI and it generates properly signed your application of xml syntax.

• Filter of time domain frequency domain filter

  Hello

  I am applying the weighting filtering of an audio signal.

  I'm to draw the response of the filter in the frequency domain.

  How can I turn this into a time domain filter and use it with a real audio signal?

  In theory, it's pretty simple. You take the s-domain transfer function and apply the bilinear transform. After a few edits, you can extract the coefficients 'food for animals-descendant' as well as the coefficients "feed-forward". These coefficients can serve as input of the filter of Labview functions. As I said, the theory is simple, but I think it will be a tough job to do this. Weighting is used in the measurements of the sound level, to mimic the curve of the human ear. If you plan to use spectral analysis in your application, you can skip the filter and apply your formula for your spectrum frequency bins. In this way, you can save a lot of work, because you stay all the time in the frequency domain.

• Error to find the frequency of signal to tachometer

  I use the vi "Extract only your Information" to find the speed of a motor.  The entrance is a monarch Laser Tach AC output.  Tach reading is very regular and the AC output is 5 volts peak.  There are a few negative pics, but these are at the speed of the engine.  My output frequency, who should read the changes back from 1800 1800 at a frequency near 5400, but not exactly 5400 (5321, etc.).  Y does it have no signal conditioning that I'm missing before signal to the vi "extract", for example, the window it and then use the frequency domain cutting-edge research?

  Thanks in advance,

  Ron

  Matt,

  Just to let you know that I put a bandpass filter in my vi.  I took the input of the speed estimated of the user and put in parentheses of the bandpass filter to be 25% below 25% above the target and the input of speed tachometer works very well!

• How to operate continuously the ' frequency with digitizer step-down converter external vi "?

  Hello

  I use SMU-5663 on SMU-1075 chassis. My goal is to use "step-down with digitizer external .vi" in order to run the SMU-6901 frequency continuous step-down converter. To do this, I added a while loop to the provided sample (see file attachment). The problem is that the while loop does not change; the program stops as soon as its launch.
  Is there anyone who can help me with this you problem?

  Hello

  The 'get frequency response' VI aims to help correct the answer of the step-down in the acquired data. The response of the step-down changes only with frequency and reference level. In your VI, you are in a loop when you call 'Get frequency response' but do not change the frequency or level baseline for the release of the VI will not change.

  To use the external digitizer, you want to adjust the center frequency and level in DAMA reference, read the frequency response and frequency step-down converter win in DAMA, to acquire data starting from the external digitizer and correct using the frequency response of the step-down, and win. You can loop through the acquisition and treatment portions until you change the central frequency or reference level.

• How to measure the frequency of a clock using meter in LabVIEW?

  Hi guys,.

  Someone knows how to measure the frequency of a signal introduced in LabVIEW (in the FPGA PXI-7813R), using a counter in LabVIEW?

  Essentially, I want to use this counter as a kind of Logic Analyzer.

  Thank you, Anoop

  I don't know what you mean by "manual".  It is all managed in a housing structure.

  

• How to provide a botton that takes a quick measure of the Isc and VOC?

  Right now I have a program that allows to measure Voc, Isc and the efficiency of the solar cell. How to provide a botton that takes a quick measure of the Isc and VOC and displays the result next the botton? I want to do this because I want to know VOCS and SAIS before hand, so that I can set the amplitude of scanning. In addition, I also want to set the initial time in seconds. At present, the time is 3 seconds, I can't find where to put them, is 3 seconds by default.

  Button not botton.

  It will be similar to what you have already in your another thread.

  Did you take the tutorials since then?  I highly recommend you do.

• How to increase the frequency of sampling of several sensors via RS - 485 and writing files of measure?

  I have a vi that:

  -Locate the USB port that RS485 communication device is connected

  -sends a command to each sensor

  -reads a response from each sensor

  -performs a calculation on the answer

  -saves the response to a file of measure

  I used a flat sequence to query each sensor.  I am trying to find a way to modify this vi in order to increase the frequency of sampling on the sensors.  Currently, it takes 2000ms for question 4 sensors and write tot the measures file.  Anyone have any ideas on how to speed up by programming?  I am concsidering on the purchase of a device USB DAQ (USB6000) and rewriting of the vi.  I was wondering if there was some tweek I caould make on the vi.

  Thank you!

  I meant put the time-out on the line, then the reading will be either timeout after 200ms or read the 2 bytes.  Whichever is faster.  Then deletes this 200ms waiting you.  I have attached your vi to show you what I wanted.  I did not notice that it is a hardware or wither then you might want to look in the data acquisition functions.  It will clean up your code and are very easy to use.

• How do you plan the frequency of a Boolean signal?

• How can I extract the frequency of the FFT function?

  Hi all

  How can I extract the frequency of the FFT function in labview?  Thanks in advance

  Concerning

  If you have the f0 and df, you can find your frequency as you would find the time with a waveform based on t0 and dt.  You just need the index of the data point in that you want to get the frequency.  The frequency is then f0 + x * FD, where x is the index of the data point you are interested in.
