• How to change the frequency of sampling DAQmx during execution?

  Hello guys. I'm using LabVIEW in the measures of the frequency response function. My application requires the sampling rate to change according to the frequency of the signal during execution.

  I tried to do it with a "structure of the event" and it works well when I change the rate manually via the front control but it backs do not work when I set up the sampling frequency to vary automatically (just a frequency sweep). Photos below:

  Why not the structure of the event feels the change in the value of "rate"?

  Thanks in advance for your help.

  Lucas

  Hello

  In "automatic mode" to change the sampling rate, the calculated rate is written in the local variable (as illustrated in the code).  Structure of the event does not change value in the local variable as an event.

  In order to make the structure of the event to recognize the change in value of an indicator such as event: write the new value to the property "Value (Sgnl)" corrosponding node to rate indicator (see figure below).  This will make the structure of the event accept the value change in the indicator as event.

  Note: Use architectures such as producers and consumers for such applications, which makes the application readable and expandable.

• Increase the frequency of sampling on the cdaq 9174 with neither 9212

  Hi all!

  I am trying to increase my sampling rate on my nor 9212, that I use with a cdaq 9174 and LV 2015. Apparently, the sampling frequency depends on the time of conversion and can be changed between the high speed, the Best 60 Hz rejection, best 50 Hz rejection, and high resolution. (see http://www.ni.com/pdf/manuals/374358a_02.pdf, page 6). My maximum sampling frequency is 1.8 Hz, which indicates the use of the mode of synchronization of high resolution

  I found this documentation explaining how to change with a crio:

  http://zone.NI.com/reference/en-XX/help/373197D-01/criodevicehelp/cRIO-9212_rt/

  However, I can't change it when the module is not in my project with my cdaq. My question is: How can I change the conversion without a crio time?

  Thank you very much!

• How to lock the frequency of sampling for 5673 and 5663

  Hello

  In general I try set the transmitter and the receiver.  It seems easy to lock the carrier frequency, but no matter what I do, I seem to have a drift in my sampling frequency (order of 1 ppm).

  Is the sampling clock in the digitizer 5663 linked to the same reference like OL clock?  ... I didn't know that I needed the mechanism TClk here since I don't care for delay...

  Any thoughts are greatly appreciated.  Here are some details.

  I use the 5673 as transitter and 5663 as receiver.  I noticed as follows:
  1. when each use a "reference clock Source' = OnboardClock I have a carrier notable offset to the receiver (for example carrier 5.8 GHz has ~ 7 KHz offset) and that's fine.
  2. when each use a "clock reference Source" = clock, with the physically attached chassis PXI, I see no delay perceptible carrier to the receiver.
  3. what 5673 uses 'Reference clock Source' = OnboardClock, using 'Reference clock Source' 5663 = ClkIn (ClkIn/Out physically attached), I see no delay perceptible carrier to the receiver.

  
  

• 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.

• How to increase the video memory on my Satellite 1800-254?

  A friend give me a Toshiba satellite 1800 Lalonde - 254 s for use only watch movies for my kids. With graphics memory, it has its impossible to reproduce movies, so I increased the RAM to 512 MB graphics memory is 8 MB. How I increase the graphics memory? Is it possible?

  Thank you very much

  Titanico

  (Excuse my English, I use a translator)

  This old laptop has a graphics card with shared memory. In other words, when you have more RAM inside more memory will be used for graphical operations. According to the specifications of the laptop this old notebook was shipped with 128 MB of RAM, but can be improved up to 512 MB.

  Trying to find internet modules two PC100 256 MB with part number PA3069U - 1. 25 M and update.
  That's all what you can do about it.

• Satellite A300-18 has: how to increase the screen resolution

  I have recently buy a Toshiba Satellite A300-18 a, and I want to increase the resolution of the screen.
  Currently the max resolution is 1280 x 800.

  Does anyone know how to increase the resolution?
  Where can I find the drivers to increase?

  Thank you

  Henrique

  Hello

  I don t think a new graphics driver would allow a higher screen resolution on your laptop A300.
  Have you checked your manual for more details?

  I downloaded the user manual of the Europe of Toshiba page and discovered that the display is a 15.4 WXGA 16Mill colors with the following resolution: 1280 horizontal and 800 pixels vertical.

  It seems that you are already using the highest available resolution and therefore you will not be able to wear to higher values.

• I want to maintain the "frequency of sampling to report signal frequency" a constant.

  I want to generate sine waves of varying frequencies, say, from 1 Hz to 1 kHz. Sometimes, a swept frequency sine wave. The problem is that I want to maintain the "frequency of sampling to report signal frequency" a constant. That means, the sampling frequency must be 20 or 30 times the frequency of the signal. This should be done automatically. For example, a sweep of 1-10 Hz, if the sampling frequency is 30 Hz at the beginning, it should be automatically updated at 300 Hz as the frequency of the signal reaches 100 Hz. Someone you will suggest a possible solution?

  The basic generating function function has an entry titled "sampling info". It is a cluster and one of the elements is the number of samples. You just need to set this based on your frequency.

  

  I suggest strongly that follow you the course 101 of LabVIEW.
