Measures of constraints with the NI 9219

• Measurement of frequency with the NI 9402

  Has anyone successfully was able to measure the frequency in SignalExpress with the NI 9402 module? I have the 9402 connected to a tachometer (on a centrifuge) which puts a TTL signal. For now, I can get the light input line to work. (Right click on the project, acquire signals: DAQmx Acquire: digital input: input line.) When the tachometer completes the first round, light or the 'blip' lights indicating the sensor then goes back to the shore for the rest of the round. I would like to read the frequency of this "blip" instead. I can't understand the required parameters in Signal Express. I tried (right-click project, acquire signals: DAQmx Acquire: entry of meter: frequency) but maybe I do not have the correct settings. This centrifuge works usually between 0 and 3 hz. I have attached a picture of what I have. I am doing this correctly, with incorrect parameters? Or is there a better way to do this? I need to read Hertz over time. Thank you!

  Hi Choover,

  Even if you use the 0 meter to measure frequency, your singal acts at the door of the on-board clock source to measure the length (and thus frequency).  This is why you must use PF1 to connect to the door of the meter.  You can learn more about how DAQmx takes measurements of meter in any manual of cDAQ chassis: http://digital.ni.com/manuals.nsf/websearch/2C061605E17C7D04862578D200677B90

• DEFAULT CONSTRAINT with the INSTRUCTION BOX - Oracle 11.2.0.3

  Is it possible to create a default constraint on a table based on conditional logic.

  For example:

  CREATE TABLE TEST_T (NUMBER OF DEPT_NO,

  GRANT_FL CHAR (1)

  );

  GRANT_FL DEPT_NO

  10             Y

  10             Y

  0               N

  I want the DEPT_NO to be filled with a default value of 10 only when GRANT_FL = 'Y' otherwise the value to 0.

  I can do that with an after Insert trigger, but would be better if this can be done via the case statement that sets a default value.

  Thank you very much!

  Kevin

  Hi, Kevin,

  Sorry, I don't think that there is a way to do it with the DEFAULT options.

  I think that a trigger is your best bet, but a BEFORE INSERT trigger would be much simpler and more effective?  An INSTEAD OF trigger is another possibility.

• Measurement of frequency with the NOR-6221

  Hello

  I would use the OR-6221 to measure the frequencies of the order of 200 Hz to 12.5 Mhz.

  Is this possible?

  Can you guide me were to start?

  There are notes of application with examples?

  The required accuracy is not high 0.5 percent more or less...

  Thank you

• Problem with the HP drivers Download Page

  Don't know where best to post this topic.

  I have problems with the HP driver download Page. Using the Chrome browser, I installed the HP product detection utility. Once installed, I admitted that it runs, and it correctly detected my HP computer and the details about this poster. A detail that he displayed was the guarantee being exceeded.

  Since I had hardware problems and had to replace the hard drive and reinstall Windows, I wanted to make sure that my computer has all the HP drivers and software required. This information would not be displayed. At first I thought it was because I had an active browser add-on. I've disabled and reloaded the page. This is where I'm having the problem.

  The product has been detected once more, but nothing happened when I clicked on the button search solutions for the detection of the product page.

  You have found the difficulty that has the utility.

  I never had a large measure of success with the utility unless I use Internet Explorer. I rarely use Internet Explorer.

• can I Exchange my nvidia geforce gt420 with the nvidia geforce gt s450 on my hpe-590 and if yes, how e

  I have a HP Pavilion 590PC and would like to know how to change the graphics card GEForce GT420 existing with the GE Force GTS450 and will there be a difference?

  Hello

  If you need improved video performance, then the answer is Yes.  You will see the difference with the video intensive applications.

  Review the performance of NVIDIA specifications. Look at the specifications of strip memory bandwidth and level of DirectX support.  Also check this comparison.

  The NVIDIA GTX 550 TI is priced in the same way to the GTS 450.  GTX 550 it is a video card faster, compared to the GTS450.  Look at this comparison.

  Open your PC and a few measurement in parallel with the PCI-E x 16 slot to see how long of a video card will fit. The adjacent slot on the PCI-E x 16 slot must be vacant.

• Large partition table with the primary key referenced by several child tables

  I tested this procedure and it works perfectly. Although when children tables refer to the key column, after execution of dbms_redefinition.finish_redef_table they all are referring to table exercised. In test I deal forced FK droped on tables children and recreated them. What could be the best way to do this in this scenario?

  Thanks for all comments/opinions!

  Are you sure? You should end up with the original FK constraint (disabled and renamed to have a prefix of $$ TMP) pointing to the staging table (which is of course the famous original table), and allowed a new constraint with the correct name, pointing to the new version of the table. so all you need to do to bring order to the top is to remove the constraint of renamed.

  This running-in of the SCOTT schema clearly indicates:

  create the table deptint in select * from dept where 1 = 2;

  exec dbms_redefinition.start_redef_table (user, 'dept', 'deptint')

  n number of var

  exec dbms_redefinition.copy_table_dependents (user, "dept', 'deptint', DBMS_REDEFINITION.") CONS_ORIG_PARAMS, TRUE, TRUE, TRUE, TRUE,: n)

  Print n

  exec dbms_redefinition.finish_redef_table (user, 'dept', 'deptint')

  Select CONSTRAINT_NAME, CONSTRAINT_TYPE, TABLE_NAME, user_constraints STATE;

• Calculated measure (OLAP language) of the calculated measure (Expression OLAP)

  Hi, once again!

  I need to create a calculated measure in the form of free type AWM (OLAP Expression, with the condition BOX) based on the results of another measure calculated again with the status of the CASE.

  For example, I have a few basic measure number of type 'BM1', 'BM2', "BM3" . And I create a calculated measure "BM_AMOUNT" that returns a number if 'BM1' is not null or 0 with the expression:

  CASE

  WHEN BM1 = 0 or BM1 is NULL THEN NULL

  ANOTHER (BM2 - BM3) / BM1

  END

  And then I create a different "BM_PT" calculated measure that returns points based on the value of the first expression:

  CASE

  WHEN BM_AMOUNT > 0 THEN 0

  ANOTHER 20

  END

  Now, when I want to create the second expression I get error: XOQ-01958derived measure is a type of invalid data or data of any kind.

  I found a way to work around this - I create first the measure with the NUMBER type and then change it to the expression of OLAP, and it works.

  However, the problem is when I export the cube and that you want to import on another instance. Then, I get the same error for this measure "BM_PT" and impossible to import the cube.

  The only way I've found is to edit the XML code and remove the measure, then create it manually as mentioned above (type NUMBER then change it), but it would be really nice if there is another way to knit this tour. This is so my question, is it?

  * The example is just to help understand what I want to achieve and what is not correct.

  Re: #2

  If you use OLAP DML, if CUBE_DDS is the name of the cube and DOOD is the name of the measure then the expression to use in the formula of the OLAP DML is _.

  Try with CUBE_DDS_DOOD, CUBE_DDS_F0150, CUBE_DDS_DO0, CUBE_DDS_SF0213, CUBE_DDS_F0180 etc., in the formula.

  In AWM, you can open the OLAP worksheet and check if the following expressions are valid by publishing a

  > CUBE_DDS_DOOD DSC

  order

  Formula:

  > If nafill(CUBE_DDS_DOOD,0) eq 0 then na to another ((CUBE_DDS_F0150 + (CUBE_DDS_DO0 + CUBE_DDS_SF0213) * 0.2) - CUBE_DDS_SF0213 - CUBE_DDS_F0180) / end CUBE_DDS_DOOD

• measure with the two channels of the virtual bench simultaneously in labview, error 375903

  Hi, I am trying two measurements simultaneously using two channels of analog input of the virtual bench. I chose the channel MSO 1 and 2 for the measures but I get error 375903 returned evewry time say the requested resource is reserved. I'm not under any other software which should use the virtual bench. The error occurs when I'm initializing the session, even before a measurement was made. Can someone tell me how to call each channel so that I don't get this conflict of resource reservation?

  I have included the VI and a screenshot of the error.

  Thank you!

  ASM takes only supported a session unique instrument and your VI uses two. To use both channels, delete the second session MSO and specify channels in the MSO configure Analog Channel.vi

  Here's an example that uses two channels brought:

• How can I measure the variable tension with the DMM and switch?

  Hello, engineer,

  I am a student, I want to measure the varying tensions from V to Via. I have the following equipment: SMU-1065 PXI-4065 PXI-2529. I use the PXI-8360 and PXI-8361 to connect with my PC. I hope I can do that when I have the next blood I should click with the mouse and connect the right position to the object of measurement.

  How can I achieve that?

  Any suggestions with great satisfaction.

  Since I know a little English, if I did not explain my question clearly, please ask me.

  Best wishes.

  Kind regards.

  Yes, you can.

  You can set the samples when using DMM.

  You can also refer to the example in LabVIEW.

• Measurement of high frequency with the NI 9411

  Hello

  I would like to measure the frequency of a TTL signal with the 9411 OR in a cDAQ-9178 chassis.  1.6 at 48 kHz frequency range.

  With examples of Labview digital frequency meter, it is not picking up on the signal.  Any advice?

  Anna

  Hello!

  After talking to an applications engineer of NOR, I realized that the input signal must be less than 5 v.  In particular, the bass is between 0 - 0.8V and the top is between 2 - 5V.

  Once I have limited input to this range, the module of frequency meter picks up on the signal very well.

  Thank you

• Import data from the .tdms file and comparing with the measured .tdms file

  Greetings,
  I want to make an application that writes the values measured in a .tdms file.
  But I want to do a separate database in a .tdms file that contains the theoretical values.
  After the measurement, the application must compare the measured values with the theoretical.
  If the application needs to read that a cell of the .tdms file.
  Is this possible?

  Thank you

• Can I use a PXI-6224 with the SCB-68 to take the measurements of 4-wire RTD, or do I need a power supply separate?

  I suspect I already know the answer to this question:

  I have an PXI-6224 M-series data acquisition card and a terminal of the SCB-68 block and want to take action using a bunch of 4-wire RTD. Is the power to the power source for these measures 6224, or is - not possible with the hardware I have?

  I know that NEITHER you propose other solutions to my problem: I am interested to know if I can do these measures with the device that I currently have on site.

  Thank you!

  Hello Jeffrey,.

  You have two options here, but it doesn't look like you need some hardware.

  The SMU-4357 built conditioning of signals, but it will not work on the chassis curent you have:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/210596/

  We also have an option with the NI 9217 cDAQ, but once, it gets you into a different platform:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/208804

  We used to have an option that we sell no more - the SC-2042RTD. If you are lucky and have one of them on hand so here's some info:

  http://digital.NI.com/public.nsf/allkb/4FF2C0F8D11B99B486256F4C006DCEA0

  You can also use these two elements in conjunction with eachother with your current PXI card:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/12311

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/10778
