How to synchronize NI-Scope and traditional DAQ

I use a PXI-1042 System with a PXI-5124 Ni-Scope Card and a PXI-6120
with traditional DAQ controlled by a PC running WinXP and LabView 7.0
The intention of this setup is to make synchronized acquisition with
both cards with different sample rates. For the sake of an example let's
assume the NI-Scope runs at 100MS/s and the DAQ (6120) with 100kS/s. The Trigger is generated by
analog triggering of the 6120. I'm looking for a solution to garanty
that for a STOP trigger with post-trigger scans the last sample of the
6120 coincides in time with the last sample of the NI-Scope 5124 card.
Or to put it in more general terms a way to identify which of the 1000
Samples the 5124 Card takes in the sample interval of the 6120
coincides with the respective sample of the 6120 ? The point is to have
a time resolution (for phase difference measurements) better than that
given by the samplerate of the PXI-6120.

Here you can find an example that shows how to synchronize a DAQ-Device with a Scope-card:

Is there any incompatibility between Labview 8.5 and Traditional DAQ?

Hi, I`m using a DAQPad 6020E and the Labview 8.5 Daq assistant don`t detecte my DAQ when a try to create a new task (to create a new virtual chanel). But MAX detect the DaqPad. So, is ther any incompatibility between Labview 8.5 and traditional Daq? Do you know how can I resolve this?
Thanks.

First, you posted to the wrong board. Measure is an old add-on for Excel.
Second, there is no incompatibility between LabVIEW 8.5 and tradtional DAQ. There is an incompatibility between traditional DAQ and DAQmx which is what the DAQ Assistant uses. Make sure that you install DAQmx if your device is supported by it. Otherwise, you will not be able to use the DAQ Assistant.

I cannot synchronize the Address Book and Calendar data, even by means of iCloud or similar servers. It appears these data are not selected automatically during synchronization. How can one select Address Book and Calendar Book in Mavericks for synchronization ?

How to synchronize audio track and video when transmitting by RTP

since the audio stream and video stream are transmitted separately on the network even if in a merged data, how to synchronize the audio stream and video stream at the receiving end ?

Hi everyone!
I've tried to make one of the processors, processor1, control the other processor, processor2, with processor1.addController(processor2) but I get a
javax.media.IncompatibleTimeBaseException. I need to synchronize audio and video rtp-streams because they are sometimes completely out of sync.
In JMF API Guide I've read:
"2. Determine which Player object's time base is going to be used to drive
the other Player objects and set the time base for the synchronized
Player objects. Not all Player objects can assume a new time base.
For example, if one of the Player objects you want to synchronize has
a *push-data-source*, that Player object's time base must be used to
drive the other Player objects."
I'm using a custom AVReceive3 to receive rtp-streams and then I create processors for the incoming stream's datasource's, and they are ALL PushBufferDataSource's.
Does this mean I can't synchronize these. If so is there any way I can change them into Pull...DataSources ?The RTP packets are timestamped when they leave, and they are played in order. You can't change the timebase on an RTP stream because, for all intensive purposes, it's "live" data. It plays at the speed the transmitting RTP server wants it to play, and it never gets behind because it drops out of order and old data packets.
If your RTP streams aren't synced correctly on the receiving end, it means they aren't being synced on the transmitting end...so you should look into the other side of the equation.

How to synchronize iPhone video and microphone audio in iMovie?

1. I have video footage captured with an iPhone 5s (roughly 7 minutes of piano).
2. I have audio footage captured with a third-party microphone (same 7 minutes of piano playing).
3. I bring these two pieces of footage into iMovie and line them up at the beginning of the clips.
4. When I start playing the movie, the video and audio are in sync. Towards the end of the movie, the video and audio are out of sync by roughly 0.5 - 1 second.
My question is how do I synchronize the iPhone and microphone footage in iMovie?
Is this a problem with the video captured with the iPhone?
Or is this a problem with iMovie not able to synchronize video and audio from multiple clips?
Note: I cannot use beat markers to solve this, because the piano playing does not fall on equal durations ("beats").

How to synchronize analog input and output from two different USB daq boards

Hi all,
I have two very differnt USB boards the NI USB 6008, which I am using to acquire the data (Analog Input) and a NI USB 9263, it is an Analog Output only board that I am using to deliver a signal (in this case a square pulse). The reason why I am not using the 6008 Analog Ouputs is because I need to deliver negative voltages and need the full +/-10V range.
Looking at similar posts I am pretty sure that I can't use an external trigger or a shared clock, I also tried to use the synchronization of timed structures but no cigar.
I am including a quick vi that I whipped out showing how the signal jitters due to the lack of synchronization. The AO from the 9263 connects to the AI in the 6008 in this example.
Solved!

How to synchronize between OID and the Custom Database Tables ?

Hi All,
Our ADF Application is using Oracle SIngle-Sign On (OAS 10.1.4). Meanwhile we also maintain
users login within Database table to store application menu accessibility data.
i.e:
Firstly user Login using Oracle SSO, after logged in, application will query the above mentioned
database tables to determine which menu he/she has access.
We have develope a security module to input users login into the database, so I need to synchronize
the data into OID, so that that particular user can use Oracle SSO.
How is the mechanism to do that ?
Thank you very much,
xtanto

Hi,
OID providesa Java and PLSQL API. I agree with Chris that from what you describe, the PLSQL API seems to be the best approach to take as it allows you to use database triggers for the synchronization

How to synchronize phone E63 and mac

i have isync..
but when i am looking for the phone - it says that it s not working..
i download the device but nothing happen..
what shall i do?
thx in advance

Hello Yingmai,
I am assuming that you are using DAQmx and also that you are just wanting to synchronize using the same board. Please correct me if I am wrong.
The NI-DAQmx Visual Basic 6.0 type library is based on the NI-DAQmx C API. Therefore, in addition to the installed Visual Basic 6.0 examples, you can also refer to the NI-DAQmx C API examples when creating a new NI-DAQmx application in Visual Basic 6.0.
Please see the following Knowledge base article for information on how to use the C examples for Visual Basic. There is a synchronization example for C, which you can use.

How can I creat virtual channel and traditional devices while my card installed,I can not do?

I installed PCI-6220 card,and I also installed DAQmx and Traditional DAQ in my computer,
but I cannot creat virtual channel at the last step(attachment:TDAQ6220.jpg).
Maybe this is the reason I didn't creat traditional NI-DAQ Device,but I can not creat it.
(see attachment: DAQ Device.jpg,there is no PCI-6220 on list).
What's wrong?What shall I do?
Junwei You

Hello Rainer,
You can see this attachment(6024E.jpg),the 6024E card appears on Traditional NI-DAQ Devices,
but I don't know how can it be created(I don't creat it,we buy the whole system together with the machine).
I tried create a new traditional Device(I want to confirm 6024E), but still I can not see any NI-DAQ device in traditional NI-DAQ device
lists. See the 'Create New....' interface.How can do it?
Thanks!

Traditional DAQ and SCXI 1530 model name

Hi all,
I am using Labview 6.1 and Traditional DAQ 7.1. I am working on one system with one DAQ card (PCI 6052E) and several SCXI cards(1520, 1530). All the SCXI cards are installed correctly because MAX can detect them all.
I want to make a program with Traditional DAQ which can detect all the SCXI cards and show their model names on the front panel.
I found in Tradtional DAQ, there is one VI called "Get SCXI Information" which returns the model types of SCXI cards, something like, 50, 51....
I found in the help file of "Get SCXI Information" VI there is some kind of the configuration file saying 51 stands for SCXI 1520. What does 50 stand for? Where can I find the complete configuration file or somehow can I change it? Like make 51 stands for something else...
Any ideas are highly appreciated.... Thank you all!

UCM - How to setup synchronize between DR and Primary site

Hi all.
As mentioned on title, we have a primary UCM site and a clean DR site. I want to ensure that end-users have ability to work with DR site for a short time when the Primary site is unavailable. To make DR site available to serves when the primary is down, we can do:
- setup auto-export archive on primary site
- target to destination archive on DR site
- auto-transfer from primary to DR site
- with data in Database, we can use Golden Gate to sync Primary and DR site
So, with these settings, I can ensure that the DR is ready to run when the Primary is down. But, if the primary takes a long time to recovered, the DR site has many new contents. How to transfer it back to primary site when the primary is came back ? In other words, how to synchronize contents (vault and native files) between new Primary (old DR) and new DR (old Primary) site ?
Thank for your attention.
Sorry for my bad English.
Cuong Pham

Hi Cuong (and guys),
I'm afraid the issue is not that simple. In fact, I think that the Archiver could be used for DR only by customers who have little data and few changes. Why do I think so?
a) (Understanding System Migration and Archiving - 11g Release 1 (11.1.1)) "Archiver: A Java applet for transferring and reorganizing Content Server files and information." This means that you will use a Java applet to Export and Import your data. With a lot of items (you will need to transfer all the new and updated items!), or large items it will take time (your DR site will always be "few minutes late"). Besides, the Archiver transfers are based on batches - I don't think you can do continuous archiving - and will have impacts on the performance.
b) Furthermore, (Exporting Data in Archives - 11g Release 1 (11.1.1)) "You can export revisions that are in the following status: RELEASED, DONE, EXPIRED, and GENWWW. You cannot export revisions that are in an active workflow (REVIEW, EDIT, or PENDING status) or that are DELETED." This means that the Archiver cannot be used for all your items.
Therefore, together with FMW DR Guide (Recommendations for Fusion Middleware Components) I think other techniques should be considered:
- Real Application Clusters (RAC), Weblogic Clustering, cluster-ware file system: the first, almost error-free, and relatively cheap option is having your DR site as other nodes in DB and MW clusters. If any of your node goes down, the other(s) will still serve your customers (no extra work needed), plus, you can benefit from "united power" of multiple nodes. RAC is available also in Oracle DB Standard Edition (for max. 2-nodes db cluster). The only disadvantage of this configuration is that it is not available for geo-clustering (distance between RAC nodes must be max. some hundreds meters), so it does not cover DR scenarios like "location goes down" (e.g. due to networking issues)
- Data Guard and distributed file system: the option mentioned in the guide is actually this one. It is based on Data Guard, a free option of the Oracle Database Enterprise Edition, which can run in both asynchronous (a committed transaction on the primary site is immediately transferred to the DR site) and synchronous (a transaction is not committed on the primary until processed by the DR site - if sites are far, or a lot of data is being sent, this can take quite long) modes. So, if you store your content in the database the Data Guard can resolve a lot. Unfortunately, not everything - the guide also mentions that some artifacts (that change!) are also stored on the file system (again, workflow updates, etc), so you have to use file system sync techniques to send those updates. In theory, you could use file system to send also updates in the database, which is nothing but a file(s) (in this case you will need the Partitioning option to split your database into smaller files), but db guys hate this way since it transfers also inconsistencies, so you could end up with an inconsistent database in the DR site, too.
This option will require some administrative tasks - you will have to resolve inconsistencies resulting from DG/file system sync, you will need to redirect your users to the DR site, and re-configure the DG to make primary site from your DR one. Note that once your original primary site is up again, you can use DG to transfer (again, immediately) changes done in the meantime.
As you can see, there is no absolute solution, so you need to evaluate your options, esp. with regards to your needs.

Synchronize system time and set system time zone in SAP

Hi,
How to Synchronize system time and set system time zone in any SAP system?

Nabarun -
Setting of the system time may be different depending on your enviroment and systems. (Windows, AIX, etc)
Windows enviroment you can use a time server or net time command, I believe its simialr with UNIX but I do not know that command.
Setting the time zone in SAP is done through the IMG in client 000. You can get there with transaction SPRO.
Once in the IMG, navigate to:
SAP Netweaver
General settings
Time Zones
Maintain Time Zones (here you can define the time zone settings/rules)
Then go to:
SAP Netweaver
General settings
Time Zones
Maintain System Settings
There you can change the time zones for the system.
Hope this helps.

This code is written using traditional DAQ but I want to chane DAQmx version.
I do not know how to code using DAQmx because traditional DAQ is very different for DAQmx.
