use the time stamp value find value Y in another waveform

Hello, there, I'm using labview 2013 sp1. I'm sorry that I can't use a picture to describe the problem.

The wizard sampling DAQ 2 waveforms of 2 channels to HAVE

Want to use mounted on board one of the waveforms as the triger to get the value of Y to another waveform (as was done with an oscilloscope)

I tried method 2:

1. the useand use to get the timestamp.

are - this method works?

the problem is how can I use the value of time I've learned very well the value of Y in other waveforms?

Thank you much in advance.

I'm sorry you use screw Express, and I'm even more sorry that you are using the dynamic data type.  Using these are not your fault, it's that NEITHER recommend for new developers, but you tend to not have as much control then you type using more stringent data and write the code yourself.

Using Split signals you can withdraw all of your signals since the type of dynamics and process data of each.  Don't know why you would use signals select but which, in my opinion, they do the same thing.  Then, you use DDT to to get your data into a format that is more useful.  Select the Conversion of a single waveform.  The explanation I gave in my previous post is valid.

Joined a VI that does what you want.  You can see that once you have a waveform and its components, you can do a much better job.  Like finding the Min and Max of a wave by using table functions.  It searches the first place where AI0 went above your trigger and then gets the value that AI1 was at this same level, which will be at roughly the same time.  Don't forget not that served it one after the other, so no two samples will be taken at the same exact time for most of the DAQ cards.  Few are simultaneous sampling.

  • seconds of falling for the time stamp

    I guess someone has had this problem before, but do not see in the forum anywhere.  I add a timestamp in a file so I used the 'get time in seconds' and connected to a "convert to DBL.  Then this son in an indicator on the façade and in the Express VI "write to a measurement file.

    The indicator shows the time stamp very well, but in the file it puts it in scientific notation and cut the last 4 digits and fractions of a second.  Timestamping writes to the file every 5 seconds, so it is important to have the rest of the time stamp included.  I tried using probes on wires to see where things are weird but I get the same value truncated in the wire before and after the flag.  I thought it had something to do with the VI Express first, given that the indicator is fine, but with her truncated in the thread, it seems that the Express VI is indeed record exactly what is given to... but then again the indicator... you can see that I've been running in circles in this!  Someone knows the reason why he does this and a possible solution?

    Thank you very much!


  • on the time stamp

    Hi guys

    I have a table and the date in a column value is stored in varchar2 (35)

    It is stored to take time up to milliseconds as below


    Select transaction_date in the table

    12:43:04:651 09/09/2009

    now, I want to vatchar2 convert timestamp data type in my table

    to keep the data in the sound and start with the exception of the new data according to the timestamp data type

    I don't know why the previous developers took varchar instead of timestamp

    our production server is in the United States and the data entered through the India and business also

    So they used the varchar data type to store the milliseconds
    Use a procedure to have time ist

    now I can change the timestamp data type without affecting the data

    I think that its really need and it is not good to store the date in varchar

    the procedure I know to change the data type is as below


    1. Create Table smsrec_dup as select Rowid Row_Id, transaction_date sms_rec;


    2 update sms_rec Set transaction_date = Null;


    3.commit;


    4 Alter Table sms_rec change transaction_date timestamp (3);


    5 setting a day sms_rec B Set transaction_date = (Select transaction_date of smsrec_dup A where B.Rowid = A.Row_Id);


    6.commit;


    above to change the data of TIMESTAMP type

    NOW, I WANT TO HOW COULD I INSERT TIME IST

    CURRENTLY developers use a procedure for STI

    AS

    CREATE OR REPLACE PROCEDURE current_tstamp (real out varchar2)

    IF var_sign = "+" THEN

    IF var_zone = "+ 05:30 ' THEN"

    SELECT to_char (systimestamp, ' dd/mm/yyyy hh24:mi:ss:ff3 "") in the double real;
    dbms_output.put_line (actual);

    ON THE OTHER

    Select to_char (systimestamp + (1/1440 * (330-(to_number (substr (systimestamp, 31,2)) * 60 +))))

    Hello

    I just want to explain about this a bit...

    change time zone at the database level is quite a bad idea...
    because if you change the time zone then what about all the data that might be present in the same database used by other applications, as appropriate.
    I'm not sure, but if dbtimezone is changed so if you have date or timestamp columns with tables so the values inside of get them adjusted to the time zone has changed.

    first of all understand the diff between...

    If you use systimestamp (which is not really a timestamp data type appear perfectly what timestamp with time zone) must always dbtimezone time zone (as obtained from timezone database).

    You use localtimestamp (which is a timestamp data type) if the timestamp at the session that you set for him. by default, it will take the client's time zone.

    If you use current_timestamp (which is a local timestamp with time zone data type), we have to the time stamp and the time zone at the session that you define for him...

    SQL> alter session set time_zone='+05:30'
      2  ;
    
    Session altered.
    
    SQL>  select systimestamp,current_timestamp,localtimestamp from dual;
    
    SYSTIMESTAMP
    ---------------------------------------------------------------------------
    CURRENT_TIMESTAMP
    ---------------------------------------------------------------------------
    LOCALTIMESTAMP
    ---------------------------------------------------------------------------
    10-SEP-09 05.15.03.531687 AM -04:00

    10-SEP-09 02.45.03.531716 PM
    
    SQL> alter session set time_zone='+04:30';
    
    Session altered.
    
    SQL> select systimestamp,current_timestamp,localtimestamp from dual;
    
    SYSTIMESTAMP
    ---------------------------------------------------------------------------
    CURRENT_TIMESTAMP
    ---------------------------------------------------------------------------
    LOCALTIMESTAMP
    ---------------------------------------------------------------------------
    10-SEP-09 05.15.39.840319 AM -04:00
    10-SEP-09 01.45.39.840350 PM +04:30
    10-SEP-09 01.45.39.840350 PM
    

    See above see you systimestamp does not change but current_timestamp and localtimestamp change with session timestamp...

    Until this is localtimestamp... speak frankly... it will get the time stamp of the client... If you use a sql developer then it will show the timestamp on your desktop... But in a 3-tier application... I mean applicationlayer-customer data base, the database client is application layer not the end user PC. He will get the time zone of the server application. So using timestamp with local time zone can be waived if you use 2-tier application or desktop.

    Here's the real story...
    So what I mean is that... This is the application layer send the time zone of the client to the database... If the database when inserting (indirectly, your willingness to insert queries) convert the timestamp to whatever you want...

    for example...
    I am inserting a record into the database table that has a timestamp data type... so... I inserted at 14:56 IST

    SQL> insert into test_tz(col1) values(systimestamp);
    
    1 row created.
    
    SQL> select col1 from test_tz;
    
    COL1
    ---------------------------------------------------------------------------
    10-SEP-09 05.25.41.497759 AM
    
    SQL> 
    

    If you see he showed he showed the time server by deleting the part of zone. Since then, you would like to insert in the TSI data then...

    SQL> truncate table test_Tz;
    
    Table truncated.
    
    SQL>  insert into test_tz(col1) values(systimestamp at time zone 'Asia/Calcutta');
    
    1 row created.
    
    SQL> select col1 from test_tz;
    
    COL1
    ---------------------------------------------------------------------------
    10-SEP-09 02.59.57.087032 PM
    

    He showed the real time of the insert as IST.

    .....................................
    If you want to set the level of the session then you must use localtimestamp as you used in your post...

    But regardless of how you use... you must spend the time zone of the client to the server, I mean 5:30 ' or "Asia/Calcutta" whatever inside your sql queries.

  • How to use the time of 80 MHz with the example of the soul base angular Position-buffer-Cont-Ext Clk.vi

    Hello:

    I use the card PCI-6602 and am a bit new to the use of timer/counters.  I use the Commission to measure the position of a quadrature encoder.

    I would use the time base internal 80 Mhz the map of 6602, but examples of LabVIEW will not allow that.  In the example, he States:

    2. call the DAQmx Schedule VI (sample clock) to configure settings of clock synchronization external sample Mode Sample and sample clock Source.  The sample clock Source will determine when a sample will be inserted into the buffer.  The 100 kHz, 20 MHz and 80 MHz time bases can serve as the sample clock Source.  The Edge parameter can be used to determine when a sample is taken.

    Is it possible to use the database internal time for my application?

    I have attached the example vi that I use.

    Thank you.

    Pat

    Hi, Pat.

    The rate determines how fast the samples are acquired and put on the material buffer.  This value depends on the basis of time, which is specified by the source of the VI DAQmx calendar entry.  The default source on the PCI-6602 map is the on-board clock (80 MHz).  The rate must be a divisor of the source.  For example, 80 MHz, 40 MHz, 20 MHz, 10 MHz,..., would be acceptable values for the entry rate.

    So the answer to your question would be to remove the entry from the source and ensure that the rate is a factor of the source.  Leaving this entry unwired will use the clock shipped by default of the unit, as shown in the screenshot below:

    I hope this helps.

  • RunTimeException when you use the timer and TimerTask.

    In the switchNext() method, it changes an image and some text in a Vertical management. When I run the application, I get a RunTimeException. However, when I have not used the timer and tested the method switchNext() with just a button method worked perfectly. How can I make it work with timer or another class that he will call every 30 seconds?

     time = new Timer();
    TimerTask task = new TimerTask()
    {
    
    public void run()
    {
    
        switchNext();
    }
    };
    time.schedule(task, 10000);
    

    It would be useful to know what Exception you actually get.

    However, I think that it is indeed related to the fact IllegalStateException the TimerTask is running in the "bottom", and you try to update your User Interface.

    If you change the code as follows, it will work the method on the event Thread and so he has access to update the user interface.

    public void run()
    {
    UiApplication.getUiApplicat () .invokeLater (new Runnable()

    public void run() {}
    switchNext();

    }});
    }

  • Can I use the Time Capsule wireless for multiple computers without using it as a router?

    I am looking for an external backup for 2 computers drive.  I have a desktop iMac and MacBook Air.  I like the idea of being able to back up my MacBook Air wireless, but I need to make sure that it will work the way I need to.

    I already have a wireless router that works well for me, I don't need the time Capsule to act as a router. I'm just needing a wireless backup drive.  So, the question is, can I use the only time Capsule as a storage device for backup of wifi or do I also have to use it as a wifi router?  My fear is that the router service is not as good as the router, I currently have.  I live in a big House of 2 floors, making it very difficult to receive a strong signal throughout the House.

    can I use time Capsule only as a backup wireless storage device or do I also have to use it as a wifi router?

    Time Capsule need to connect to your router/modem existing using wired Ethernet wired, permanent.

    If you plan to use the time Capsule to back up your Mac with the help of the application Time Machine on every Mac, the Mac will have to save on the wireless signal Time Capsule for the process to be officially supported by Apple.

    While it is possible to turn off wireless on the Time Capsule and try to save it to your existing wireless network... and it pourrait work... but there will be no Apple support backup problems... so it would be a good idea to plan to use Time Capsule wireless backup purposes.

  • My verse ATT modem (non apple devices to use this modem} is connected to the ATT line, Time Capsule (iPhones, Macs Time Capsule use) via ethernet Uverse.) Non apple devices can collect data from iPhones or Mac using the time Capsule?

    My verse ATT modem ({use of devices not apple wifi of this modem} is connected to the ATT line, Time Capsule (iPhones, Macs use the wifi of the time Capsule) and connect to the Uverse modem via ethernet.)

    Both devices are set to the highest security and each uses separate passwords.

    Non apple devices can collect data from iPhones or Mac using the time Capsule?

    With a bit of work by someone who knows how to do such things, not Apple computers could read some files on the Mac if file sharing is configured on the network... devices non-Apple and... He knew the device passwords or administrator for Macs.

    Mac could also play the files on other Macs if file sharing has been implemented and the device password or admin was known.

    If you ask if a PC can read the files on the Time Capsule, the answer is Yes, without doubt, assuming that the PC knew the password of device for the time Capsule.

    If you want to make sure that you will be able to get the Apple support in case of problems or questions with your backups, you must use the wireless Time Capsule to back up your Mac.

    As long as the time Capsule provides a wireless signal, you can decide who to your 'main' network, then use it wireless Uverse for "guest", or children. If you do not need the Uverse router/modem wireless at all, it is possible to turn off wireless on the device and make it work only as a support modem/router...with Uverse wired.

    At this point, you can start thinking about how you want to configure things and get back in touch if you need some advice on how to do it.  We need to know what operating system that uses the Mac that you normally use to administer the time Capsule, provide good instructions, if you need it.

  • Hello! I use photoshop elements 12 and I just set a new model. Using the pattern stamp tool, I'm brushing my boss on my photo; However, the model will be released in checkerboard and I don't want it to be checkered, on

    Hello! I use photoshop elements 12 and I just set a new model. Using the pattern stamp tool, I'm brushing my boss on my photo; However, the model will come out in checkerboard and I don't want be check patterns, only the template itself. I tried checking and unchecking the box alignment, but it doesn't seem to change anything. How to brush on the model without making a checkerboard pattern.

    Well, defined bosses are in fact repeat patterns, that is why your seeing what looks like multiple images of the same thing.

    This means that if you try to cover a larger area than the initial size of defined pattern, the pattern is repeated.

    What you could do is to make a selection of the area you want to fill the (flower) pattern with and go to layer > new fill layer > model

    Use a combination of the scale slider, then move the model on the image until your happy with the set up.

    (while the Model dialog box fill is open you can click on the area of document and move the model)
