• How to read the measurements of the model eye?

  I'm new in LabView. I use an Agilent54855A to capture a model high-speed digital and want to read these measures of model of the eyes, eyes for example height, width & vice versa of the eyes. However, I couldn't find this VI in the palette.  I can read it on the screen, but do not know how to retrieve through LabView. What should I do?

  Steve,

  Thank you. There are commands to read the eye measures model. I'm changing the existing VI to add these new features and then I will check next week.

  Best regards

• usefulness of reading the measurement file express vi

  Hello

  I found reading file express vi measure in LV7.1 does not read from the beginning of the file when you run it the second time. Instead, it resume from where it left off last time. Usually, the user would read the entire file measure each time. So when you try to read the second time, it will show an error window saying that it has reached the end of the file (because he was reading the entire file first).

  I wonder how useful to resume from the last stopping point is? Is there a way to start over each time that the VI excute it?

  I'm sure that's how reading file measure works 90%. Whenever she is called in a single run of the application, it will start off the coast where it was stopped. You will need to work with the low level screw to get what you want to do.

  This Express VI works in a similar way the screws and the following functions:
  Open/create/replace file
  Read text file
  Read binary file
  Read the spreadsheet file
  File dialog box
  Scan to file

  And, you can always use the node to set the file Position to set the position at the beginning of the file.

• NOR-DMM vs IVI - DMM - Soft Front Panel

  Hi all

  I've developed a test application that will subsequently use a PXI-4070 DMM (currently simulating it OR max).  I used the IVI DMM functions, but ran into a problem when I couldn't do a diode test (diode test is apparently not officially normalized according to by IVI yet).  So I've been using the functions OR DMM. Essentially, it's a pretty seamless transition, but there is one thing that I was not able to replicate with the NOR-DMM simulation I could do with the IVI - DMM.  When I used the IVI - DMM features and ran the VI, an open popup that enabled me to get into the simulated value I wanted the DMM to read.  I can't get this to work with functions OR DMM.  Is this possible?  If Yes please let me know how to activate it.  Thank you.

  The advanced simulation exists only on the level of Class IIA (IviDmm) driver. Class IVI drivers implement the functions of simulation using pilots of the simulation. IVI Compliance Package (PIC) installs a driver simulation for each class IVI driver. Each pilot simulation of plugs for the pilot of the corresponding class and performs the simulation of flexible output data. The NOR-DMM is a specific driver that supports the DMM series NOR and therefore does not include the functionality of advanced simulation.

• Simultaneous digital writing and reading w. measurement interval

  Hi all

  For the last couple days, I've been trying my brain trying to get a program to run.

  I am trying to generate a camera digital 4 output bits then simulatanously count edges mounted on its LSB up to an arbitrary number set by the operator of the program, how the program should be a measure.

  I note, however, that, on a certain edge County number growing (~ 950 or almost), the program crashes. The problem persists even when I remove the function that reads the LSB, although, in this case, accidents occur to a much higher number. What could cause this? Is there a way I can work around this problem?

  Here is my code:

  arraySizeInBytes2 = 8
  
  bufferSize = 255
  
  ReDim readArray (arraySizeInBytes2)
  publicLifetime = 100' use this to control the duration of the task takes

  Thank you.

  You were right: it was a buffer overrun. I was using integers when I should have used doubles.

• Read file measure to XY Chart of waveform

  Something pretty simple that gives me a hell of a time right now.

  I have a .lvm here who was rescued from an acquisition of data and has a column of numbers from 0.0000 - 27.0000 to very small no. The next column is the amplitude of the signal at the point. Now this file LVM I'm starting a new vi and I want to read those values x and Y and get them on a waveform graph. Now, I tried hanging 'Reading a file measure' and tried to "Build the Table", but who do not want to connect on a chart. Rather the file directly on a chart causes two very different lines is displayed but is no where near what I'm looking for.

  Some tips on how to complete it?

  Tasty,.

  More often than otherwise, I find screw Express to be more trouble than they are worth. Here is an example of reading data tab delimited in a .txt and tracing the values of are against X a value on a chart. It will be useful.

• How to use DAQmx Read to measure several analog channels

  I have two analog inputs using USB 6221 and I want to measure the voltage of each of them.  I use vi DAQmx-read and I select input analog, 1 sample, several channels, but I do not know how to connect several channels at the entrance of the physical channel.

  Hello, Bernadette.

  For reference - I would recommend ad DAQmx questions here:

• read from measure Makefile slow while loop

  Hello

  I'm using Labview for controlling a lower Member brace. What I did is to save in a spreadsheet, the values of two angles in a random walk. The control template is done well because I tested it by giving two sine waves with different frequencies and the system responds by following paths. The problems begin when instead of sine waves, I put the experimental values of the read angles and "the file of the measurement reading. I can't change the speed of the system by varying the time while loop. The speed is always the same.

  In the vi attached is possible to find this piece in the upper left corner of the while loop.

  I use windows 7, 2013 and cDaq-9178 labview.

  Thank you in advance for the answer.

  Best,

• Value previous reading of measurement

  Hi people.

  I have a problem here traditional of the program seems to be implemented of the second frame before the first image in the sequence. The measured signal is the previous value that was generated. Labview is a sample behind what I see on my real oscilloscope when I press the button of "Amplitude". Why is this the case?

  Thank you

  Select this option.

  Your vi is pretty hard to read because (a) I don't have this scope driver installed so that the blocks are empty and (b) the façade extends over an area larger than my screen!

  This aside, the default setting for the entry VISA that you allows to send the AMPL command is "asynchronous" - which means that the course of the program will not wait until the chain was sent before moving on to the next section. The scope read probably begins before execution the first character has been sent. It will take a finite time to send the string depending on the speed of appreciation (or not chosen) chosen transmission, and the FG will take time to set up the command and change the output.

  The read scope, in the meantime... the read scope triggers a new acquisition or simply collated the latest wave existing buffer? I suspect you want to trigger a new acquisition AFTER the FG has had time to process his order, and I suspect that it is probably just to return the wave that he acquired for the last time before the FG has been changed. It is assumption that I do not have the manual.

• How to find the sampling frequency to read the measurement file

  I would like to find/extract the sampling frequency of a .lvm file.

  Right now I am using the VI 'read file of measurement' and my data charge fine and all, but I need the frequency of sampling for certain calculations.

  I know the header of the file .lvm that the sampling frequency is 1613Hz, but I want to get this automatic information from the open file .lvm.

  I'm sorry if this question already answered, but I could not just to find the answer.

  The timing is part of the production of signals information. Never use the functions of the Express, but you can use DDT to and convert to one of the data types of waveform. Waveform components then turns the dt.

• Read file measured (bad)

  I have a VI where I save data by using the "write to file measure utility". When I open the .lvm file in Notepad, I see all the data correctly, but when I use the 'Read of a file as' tool and try tho make a graph the data presented is not correct. Attached .lvm file and an image of the graph as labview using the file "read measurement. If you open the lvm in Notepad, you see that the duration column goes up to 22 sec. In the chart, the time axis will only up to 7.5 sec. What's not? Thank you

  PS: I changed the .lvm in .txt file to attach

  I have use Bundle.  I used Index and Bundle.
