thanks Jeff Bohrer  for your reply, what i mean is the y-axs of the plot is in DB aleady, but when i export the data to excel i will be seeing the gain in 0.8, 0.7,0.4 which is not normal,  which will not give me the -3db point of the gainband width product of the circuit
What you want to do is plot the Log(10) of the frequency on a linear axis!!!!!!!  The export - exports the values not the axis scale.  exporting a log(10) of the Y axis will export the log of the axis- (of couse, you could change the graph axis scale in Excel too...... but)

  • How to get lab view to display my plot in DB

    hi guys
    i desigED n an operational amplifier to determine the gain product band width using a 741 chip and the gain of the circuit is 1000, meaning that the gain bandwidth PRODUCT  will occur at a frequency of 100hz. but i have a problem, when i start the frequency sweep from the function generator from 10 hz to 100Khz which  IS the final frequency value i have set for the program. when the lab view program stops and i export the data to excel sheet i will be getting the DB axis value in a SMALL VALUES AND IN DIFFERENT  UNITES  WHEN I PLOT THE GRAPH USING EXCEL,  while the frequency is in log10.
           pls can any one tell me how to solve this problem to start getting the right cut off  frquency on the graph. find aattched my vi and the excel data from the vi that is in a different unit not in DB

  • How to get bode plot in lab view

    Hi all,
    I'm just starting with lab view.
    We have NI PXI system.
    I need frequency responce of a servo motor i.e.  bode plot,
    I'm using labview 8 ,we have PXI 7352 motion controller.
    I'm very confused as where to start and what is the in put to the motor.
    can any one help me?

    Hello,
    I'm not so sure that using a motion control card is the way to go about finding the frequency response of a servo motor. In order to do this, you would give the motor a varying sinusoidal voltage and then measure the voltage output of a velocity sensor. Here is a link to a document that goes through the process: ftp://ftp.ni.com/pub/devzone/epd/lab5_frequency_response.pdf

  • In search of Projects based on Lab view.

    Hi,
        Iam Chaitanya, pursuing M.tech.. Iam using Lab VIEW,it is a good platform to work in realistic so I interested to do Lab VIEW projects. Can you please suggest projects based on Real-time applications or electronics.

    Hi Chaitanya,
                         In real time application you can go for the projects like dataloggers which having communications. Here all the operations on datalogger can be done using labview. You can plot the graphs, show the RTC, download and process flash & eeprom memory and so on.
    Or you can go for TCP like projects where some equipments are sending data using TCP and you are reading that data using TCP tools in labview and write to database,excel and plot it later.
    Its all depends on you what you want.
    Thanks
    Kudos are always welcome if you got solution to some extent.
    I need my difficulties because they are necessary to enjoy my success.

  • Looking for lab view example

    My application consists of collecting data from a bank of sensors as pressures and tempratures vary. I would like to run a lab view VI that tests the sensors, varies the environment and keeps track of all results, sorting them into good and bad. Each sensor needs to be tested in different pressures, then the temprature increases and the pressure test begins again. If there is a lab view example that might be able to get me started, I really need to find it. Thanks for any and all help.

    There are a number of examples that ship with LabVIEW and their usefulness will depend on information not specified in your questions - such as what version of LabVIEW you have, what type of DAQ card(s) you have, and if you are using any SCXI hardware. If you open LabVIEW and go to Help >> Find Examples, you can search through a number of different examples.
    For the application it sounds like a good place to start would be with an Acquire to Spreadsheet type of file that reads, graphs, and logs data. From there, depending on what you mean my using the card to vary the environment, you can find other examples of AO and DIO to perform these type of functions. These examples will give you a good starting place as to how a LabVIEW program works and the general flow
    that you will need to follow.
    Also, depending on your other needs, you might considering looking into examples with triggering to enable you to control when your program starts.

  • How to configure a shell and tube heat exchanger with Lab VIew to get data

    HiI
    In our undergraduate chemical engineering labboratory we want to configure our shell and tube heat exchanger  with a DAq and Lab VIEW to get information about the temperaure (of the cold fluid stream being heated), the pressure (of the steam on the shell side of the heat exchanger) and the flowrate (of the water being heated).
    Can anyone suggest thermocouples, pressure transducers and flowmeters to fit between the heat exchanger and the DAq?
    P.S. the heat exchanger is already fitted with thermometers, a pressure gauge and a rotameter but we don't know how to connect these hardware to the DAq
    Solved!

    It sounds like you have enough information to pick out appropriate sensors, you just need to do the research. I would start looking through the Omega catalog, or give them a call - they're usually helpful. I can't take the time to spec out parts for you - that would be a lot of time spent on someone else's project. Most pressure sensors put out either a 4-20mA or 0-5V signal, either of which you can read through an analog input on a DAQ; measuring a 4-20mA signal requires a resistor to convert to voltage. Most of the NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware does support reading thermocouples. For accurate readings, use a device that has built-in cold junction compensation - for example, the SCB-68 connector block - and for the most accurate readings, get a board specifically designed for temperature measurement.
    For the flow measurement, a standard, simple solution is an orifice plate. You put a differential pressure transducer across it, look up the appropriate equations, and use them to calculate the flow rate given the density of the fluid (which you'll be able to calculate from the pressure and temperature, since steam tables are widely available). There are other differential pressure devices available as well - at a previous job we used a V-Cone from McCrometer. If you call them they'll spec one for you - but get an approximate cost first to make sure it's within your budget.

  • Communication between Lab view and Controller via USB

  • How to control a NI USB 6210 from a Lab View program?

    Hi,
    I started today with Lab View with some earlier experience long ago.
    While it took me only about half an hour to get my first program running (great), installation time nor included (of course), I meanwhile read documents for some hours and cannot find out how to control measurement hardware in Lab View.
    I want to use a USB 6210 to set a 1-bit digital port. But at the moment there is no USB6210 available so I wanted to write (or do you say draw ?) the program without it and if possible simulate the hardware.
    I drew DAQ Assistant into my block diagram and selected digital line output but get "No supported devices found". I don't know if the appropriate driver was installed during Lab View installation.
    Also I don't understand the mechanism between DAQmx, tasks and the real hardware. Now I have a "Digital Bool 1Line 1Point" Control in my block diagram. How do signals get from program flow to hardware pin? How can I create a simulation for not connected hardware?
    Any help is greatly welcome
    Thanks a lot

    Launch MAX, it was known as Measurement and Automation Explorer, there should be a shortcut in your start menu / desktop.  Under devices and interfaces you can find your hardware and open test panels to control it.  This is the first place to ensure your hardware is working.  If the device isn't seen you'll need to install the drivers and DAQmx software.  If it is there, great.
    Now launch LabVIEW.  The easiest way to control hardware is using the DAQ Assistant.  It has many limitations and isn't recommended for large applications.  But for something quick and dirty it works fine.  You'll find it under the Measurement I/O >> NI DAQmx palette on the block diagram.  If it isn't there you may need to reinstall the DAQmx drivers.  This can happen if you installed DAQmx before LabVIEW.
    Also you'll find under Help >> Find Examples on the toolbar, many examples on controlling hardware.  Feel free to post some code if  you are having problems.

    I have a problem with running an EXE file on win2000, the Lab View is 5.1 and I do not know if it is 16 bit...what should I do?

    Hi Arika,
    The drivers that you need to install to make your executable work depends on what your executable is doing. To get started, you need to have the LabVIEW Run-Time Engine installed on your target machine (the Win2000 machine you are planning to use) in order to run your executable. Next, you need to determine what drivers your executable uses, if any. For example, if you are using GPIB instrument control, you will need to install the NI-488 drivers on your target machine. If you are performing data acquisition, you will need to install NI-DAQ drivers. If you are doing image acquistion, you will need to install NI-IMAQ drivers.
    All these drivers are available for downloading on ni.com. To get the drivers, go to ht
    tp://www.ni.com/support , click on the link that takes you to Drivers and Updates (under Option 3), and click on the links to get to the driver(s) you need. For example, if you need the LabVIEW 5.1.1 Run-Time engine, click on the All Drivers and Updates by Application link on the main page (http://www.ni.com/softlib.nsf/). Then click on the LabVIEW link, Windows 2000, Run Time Engine, and then you will see the link to get to the page to download the LabVIEW 5.1.1 Run-Time Engine.
    I hope this information helps.

  • Create test sequence from lab view - add it to the .seq file

    Hello All,
                   I have a query. consider an test sequence that has already stored in "Test.seq" format. let us say we have 5 test steps.
    now is it possible to add a new test step to this existing test sequence using Lab VIEW. I mean if we enter a new test step this has to reflect in the existing test sequence "Test.seq".  i.e in the "Test.seq" we must have 6 test steps.
      If this is possible let me know how this can be done. 

    Michels,
    Guenter mande a very good point.  Make sure to take a look at the forum thread he linked to see the licensing implications of creating your own Sequences.
    There is a very good forum thread that discusses how to create steps programmatically.  You can find the forum here:

  • Versions of lab view

    Hi:
    Im trying, to find a way to search, a file stored in different subfolders of a main folder, and copy, i mean i have a VI which makes a folder everyday (the name istoday date, or yesterday date), and inside that folder is a serial1.txt log file, but yesterday (for axample) the same log file (serial1.txt) was generated, how can i search in lab view all of those serial1.txt files?? By putting just in the search field, the main folder name??? 
    And I want to copy each of these serial1.txt, to different paths???
    So in this days, i ve working and the file is ready, but this archive just search like this: main directory /2nd directory/ 3rd directory/Files.... I mean if the files is deeper in more subdirectorys, does not work well works for me.

    I don't know if you are still asking the same question in this thread or not. If you are, don't start a new thread. 
    As far as the exe, all you have to do is install the 8.5 run-time engine on the other PCs. If you had created an installer (something you should always do), the run-time would have been included.

  • Iam using a table in numbers to plot daily graph lines. If I fill a cell with a text box  at say zero it plots the graph. I can't actually set the cell value until the actual day but the graph plots it at zero when I don't want it to plot anything. Is tho

    I am using a table in Numbers to plot daily graph lines. Mood swings of how I am on the day, i"m a depressive.
    If I fill a cell with a step box at say zero it plots the graph. I can't actually set the cell value until the actual day but the graph plots it at zero when I don't want it to plot anything. Is there a work around. so thatbgraph only plots on the day?

    The answer is (sort of) in your subject, but edited out of the problem statement in the body of your message.
    When you use a stepper or a slider, the value in the cell is always numeric, and is always placed on the chart if that cell is included in the range graphed by the chart.
    But if you use a pop-up menu cell, you can specify numeric or text values in the list of choices for in the menu. Numeric values will be shown on the chart. Text values will not.
    For the example, the values list for the pop-up menu was:
    5
    3
    1
    Choose
    -1
    -3
    -5
    The first pop-up was set to display Choose, then the cell was filled down the rest of the column. Any text value (including a single space, if you want the cell to appear blank) may be used instead of Choose.
    For charts with negative Y values, the X axis will not automatically appear at Y=0. If your value set will include negative values, I would suggest setting the Y axis maximum and minimum to the maximum and minimum values on your menu list, rather than letting Numbers decide what range to include on the chart. Place a line shape across the chart at the zero level, and choose to NOT show the X axis.

  • How to determine the slew rate of an amplifier using lab view

    gud evening all
    I have an op amp circuit built on the NI ELVIS board and I input a square wave from function generator to the circuit. I have to determine the slew rate of the op amp.In the labs, one would run the square wave over a range of frequencies and stop when the square wave looks like a triangular wave. At that frequency, one would then measure the slope of the signal and that will give you the slew rate. How can I do that in LabVIEW? How can I check when my square wave starts looking like a triangular wave? please help
    good
    good

    thank you johnsold
    i designed a voltage follower using 741, on an Ni elvis instrument. i can manually do the slew rate experiment by varying the frequency range on the coasre frequency knob( using a square wave) of the function generator until the slew rate occurs at 0.5volts, my problem is how can i do the same experiment with built in vi in labview with out touching the knob on the function generator and once the triangular wave starts to show the lab view program will automatically stop.
