• How to calculate the average of the 1 d array?

  Could someone please help me, how can I calculate average of the 1 d array? For example, if the table 1 d - is [2, 3], I would get average = 2.5. Thank you very much!

  Use the average function. You can use the search or the quick menu to look for where you don't know where to find.

  How do I reverse Split 1-d Array of recombining the splitting table? IE I have two Boolean charts A and B, and I want them in a Boolean array: a followed by B items (NO interlacing) array elements

  Thank you

  Hi ysma.

  -You cannot convert SGL data directly on the Boolean chart that shows you the Red CoercionDot...

  -always do not concatenate you the berries (despite all the comments on this subject), but instead to create a 2D array...

• How to increase the sampling rate in this VI?

  Hi all

  I have recently inherited this mess of a VI and can not figure out how to increase the sampling rate. I tried to change the "ms of waiting ' clock, but it does not add more data points." The main VI, as well as the Subvi, which contains a Daq Assistant to a load cell and LVDT is attached. Any ideas on how to improve the sampling without a complete overhaul would be greatly appreciated!

  Thanks in advance!

  If you are grateful, feel free to give congratulations and mark the topic as resolved.

  Thank you

  does not the loop move on to the next item in the loop, it mearly incraments var I.

  is actually the loop switch the order of the day. It's inevitable, because I is the loop index.

  In any case, as others have suggested, you can skip the history quite i. Just follow your instinct and code it directly as you feel.

  I want to check each line but if there is a mistake in any column in the same row I want to ignore the whole line

• How to create a waveform from an array with arbitrary sampling rates

  Hi I know that sounds a little silly,

  Suppose I created a simple table of figures DBL with a structure For, Say size 16. now, I want to create a waveform DBL with these 16 numbers at an arbitrary sample rate. so if I use 1 kech. / s to the sampling frequency, I want to have a waveform with a duration of 16 milliseconds.

  Please help me, I need it too

  Hello

  You must use the wave to build function as shown here: http://zone.ni.com/reference/en-XX/help/371361G-01/lvwave/build_waveform/ . Wire you your Board at the entrance Y and then wire the dt of entry in your sampling rate.

• How to draw the average sensor values against an array of constant (long positions)?

  I have 7 microphones where I take the RMS value.  They are physically located in a line, and I would like to draw their values against their positions.  How can I think.  I guess I'll need to use the XY plot, but I don't know how to turn the 7 signals into a single table and how to create a table of constants for the positions.

  I think that I have, there are however a large number of conversions.  You see somehow I could simplify this, or is it as simple as I'm going to?  I have included my file to the post.

• How to set the sampling interval using DAQ hardware?

  Now I have a sensor capability and hardware DAQ 24 bit (http://www.mccdaq.com/usb-data-acquisition/USB-2404-10.aspx).

  The DAQ hardware has the 50kS/s maximum sampling rate. My question is how to define the range of data collection. For example, if I set the sampling rate of 2000, continuous sample mode, I use read.vi DAQmx in a while loop and set the "number of samples per channel" to 100. I want to plot these data over time using a XY Chart and also save this data. So I add a 'Medium' function to get the average of 100 samples per each loop (medium, there are 20 release of data per second). But when I put a 'number of samples per channel' much more small (for more data per second), there are a few problems. It seems that the program cannot read the data as much and get the average at a higher frequency. I don't know where is the problem. Overall, the collection of data more frequently? Maybe I didn't articulate my question. I'll upload a simple program later if necessary. Thank you.

  
  

• How to add corresponding elements of two arrays in a continuous acquisition?

  Hi all

  I am writing a program (in version 9.0 of labview) to acquire the signal of a fast set. I use the acquisition rate of 1.25 Ms with an external trigger. Now what I need, is to add the "n" data these acqisitions and then further process.  E.g. If I signal to 200µs acqiring can total number of data points with the acquisition of 1.25Ms rate will be 250. I'll get a table 1 d of 250 data points whenever I run my acquisition.

  Let's say Array 1of acquisition number 1, 0.1, 0.3, 0.5, 0.6,... up to a total of 250 data points

  Table 2 of the acquisition by number 2, 0.4, 0.5, 0.8, 0.4,... up to a total of 250 data points

  ----------------------------------------------------------------------------------

  Added table should be 0.5, 0.8, 1.0, 1.3... .route to a total of 250 data points

  -----------------------------------------------------------------------------------

  To do this, I need first to save the table of acqisition number 1, then run the No. 2 acquisition and add points of data corresponding to the saved table. This should continue at a nuber defined by the user to purchase say 10, 20 or 50... I don't know how to do it. Can someone help me with this problem?

  Thank you very much in advance

  Kind regards

  I guess that time avarages and acquisition will not change during the measurement, so keep a cela outside loops. If you know your settings for made her make it constant.

  you create task (outside the loop) and a narrow at the end.

  Avoid the dashboard generation where possible. With no.. AV., and no. acq.points declared, the size of the arrays is fixed and you can (re) use a single Bay and replace the elements in the array.

  No need to collect all the data and avarage them after the rally. Just add

• How to specify the sampling frequency? Must use "measurement &amp; Automation Explorer '?

  I use to measure the input current analog OR cDAQ-9171 (chassis only location USB) and NOR-9207. I have 2010 NOR-installed DAQmx and LabVIEW.

  How can I specify the sampling frequency?

  If I use M & A Explorer to create the task, I can specify the flow rate (Hz) on the Configuration tab-> sync settings.

  For the acquisition of data NOR, it is mandatory to use M & A exploring?

  If I don't want to use M & A Explorer, how can I specify the rate (Hz)?

  Hello

  You can specify the sampling frequency with "DAQmx Timing.vi" located in the function palette DAQmx (read context-sensitive help on how to use wisely).

  You do not have to use M & A exploring (MAX) to create a task.

  A simple and quick way is to use DAQ Assistant (same configuration as in MAX) to configure your measurement.

  Another is to use blocks of DAQmx function to manually build your application code.

  In my experience Assistant DAQ is ideal for simple tasks (one measure), with regard to the more complex measures (synchronized the analog and digital inputs).

  I tend to use function blocks because they give you more freedom about code execution.

  Note: You can also build DAQmx code from a wizard configured DAQ task.

• How to case statement based on the array of values of 3 or more?

  I'm trying to figure out how to do a comparison or case structure... based on the creation of an array of boolean 3 (or maybe more).

  I have a table (it's from a serial connection, and I am conversion back to a table to work with) [t, F, F] in this case I would like to display on a status indicator "STBY".

  If the array is defined on [F, T, F] I want to display in this indicator "ON".

  If the array is defined on [F, F, T] I want to display in this "EMPTY" indicator

  I can not understand how to compare combinations of things... I read in an array of bytes, and the first 3 bits in this example, determine what to display in a status... I can't figure out how to do with structure case... or without some channels to research and/or bad comparison...

  Any suggestions?

  Thanks in advance,

  Cayenne

  You can use search 1 d array and find the first real.

  Or you could convert the table of Boolean integer U8 and integer that results to determine which cases to run.  (4, vs, vs 1-2)

• How to adjust a size of "control array".

  I have a program that creates a Digital PWM with duty ratio variable. Changes in cycle duty every 50 ms, but the frequency of global wave remains at a frequency determined by the user. I have attatched to VI.

  My problem is the following... I need to be able to control the overall cycle time. This means that the size of my table to cycles it will have to adjust depending on the time of the cycle (either a duration of 1 second would require 20 slots of 50 ms, while a second 1.3 cycle would need 26).

  I currently have only 4 slots in my table, which means the total s est.2. I understand how to manually add and remove items in the table, but I can't understand how to add a control to it so that the size of the table changes automatically, allowing much more rapid data entry. Right now I can make it work, it takes just super long to add or remove items from the table. The perfect situaton would have a constant control for cycle divided by 50 times, that would change the size of the array.

  I can't find any info on this, and I think I've even seen a message asking to add this kind of functionality. I am relatively new to this program.

  Thank you

  You can do this in two ways.  You can have a constant matrix with the maximum number of ellements you need and then use the subset of table to select the part you want.  The second option is to use the array to initialize and connect the entrance to size of the array to your control.
