Acquire data from agilent dso 3104 in avraging mode

Hi. I’m trying to use the Oscilloscope Agilent DSO-X-3104 A with the LabVIEW 2010. My problem it’s about read a waveform for a channel, when I had configured the acquire mode on average. I.E. When I use the example code “Read Waveforms (Single).vi” located in the public data directory of the “Agilent 2000 3000 X-Series” I read the waveforms when the acquire mode is normal (the example code could plot the waveform), but when it’s on average, I don’t obtain anything (the example code couldn't plot the waveform). Maybe there is something that I’m not considering, could you advise me?

I am running labview code for DSO "Agilent 2000 3000 X series" (downloaded from http://forums.ni.com/ni/attachments/ni/140/47325/1/agilent_2000_3000_x-series.zip). VI examples: "acquire waveform single" / "acquire waveform continuously", but it only acquires in normal mode. whenever i change to average mode manually or through "configure acquisition" VI, i get the same error message: No data for operation on PC as well as oscilloscope and Query unterminated.
Pl find attached the error message.
If i run "read current waveform" VI , even then , averaging mode is not being supported.
I have not changed the default time out values in the default VI's or sub VI's. Pl advise on what values to take for sampling in 5Gsa/sec and averaging mode in 256 samples DSO setup.

Unable to consolidate data from two DSOs into an InfoCube for reporting.

Hello Experts
I am working on BW 7.0 to create BEx Report as below:
This report will have data coming from two different sources, some data from COPA DSO [such as Customer Number, Product Hierarchy1, Product Hierarchy2, Product Hierarchy3, Product Hierarchy4. Product Hierarchy5, Product Hierarchy6 and a few other Key Figures] and the rest [such as Product Hierarchy, Reference Document, Condition Type (both Active & Inactive), Condition Value and a few other Key Figures] from another DSO (ZSD_DS18) which is a copy of the BCT DSO (0SD_O06). I've chosen this DSO because this is the BCT DSO which is used to store data from a Standard Extractor 2LIS_13_VDKON.
Below are the screenshots of these 2 DSOs:
I have successfully extracted the data from 2LIS_13_VDKON (includes PROD_HIER but not Customer Number) and loaded into a DSO (ZSD_D17).
All the testing is done using only one Sales Document No (VBELN).
First test that I tried is.. to create an Infocube and loaded data from ZCOPA_01 and ZSD_DS18 and when the LISTCUBE was run on this InfoCube, the data is coming up in two different lines which is not very meaningful. Screenshot below:
Therefore, I have created another DSO (ZSD_DS17) to Consolidate the data from ZCOPA_01 & ZSD_DS18 establishing mappings between some of common Chars such as below:
ZCOPA_01                    ZSD_DS18
0REFER_DOC <->        0BILL_NUM
0REFER_ITM    <->        0BILL_ITEM
0ME_ORDER    <->        0DOC_NUMBER
0ME_ITEM        <->        0S_ORD_ITEM
51 records are loaded from ZSD_DS18 into ZSD_DS17 and 4 records are loaded from ZCOPA_01 into ZSD_DS17 for a particular Sales Document Number.
When I am using a Write-Optimized DSO, data is coming in just 1 line but it is showing only 4 lines which is aggregated which is as expected since W/O DSO aggregates the data. However, when I use Standard DSO, the data is again splitting up into many lines.
Is there something that I am missing in here while designing the Data Model or does this call for some ABAP being done, if so, where or should I have to talk to the Functional Lead and then Enhance the Standard Extractor, and even if I do that, I would still have to bring in those Key Figures from ZCOPA_01 for my reporting?
Thank you very much in advance and your help is appreciated.
Thanks,
Chandu

in your (current) InfoCube setup, you could work with "constant selection" on the key figures
for the COPA key figures, you'll need to add product hierarchy to the key figures with a selection of # and constant selection flagged
for the SD key figures, you'll have to do the same for customer & the product hierarchy levels (instead of product hierarchy)

How to acquire data from multiple dataports at the same time

Hi,
I studied the multithreading section of Labview, but still have no idea
how to make it work. Let me briefly explain my situation. I need to
develop a program that can control and acquire data from 4 serial
ports. I have 4 buttons to control starting or stopping acquisation
from the corresponding port. Every acquisation process is a while loop.
How can I start a new acquisation loop (eg. from COM2) while the loop
for COM1 is still running? In other words, I wish the 4 loops running
independently, and are controlled by their corresponding buttons only.
Thanks for any suggestion.
Jin

Hi Anonymous,
If I were you, I'd create one VI (call it Port.vi) to listen to one port - then make it reentrant. Drop 4 copies of Port.vi on your Main diagram. Port.vi inputs could include a VISA reference, a "Start/Stop" notifier and maybe a "Quit" occurance. Wire to each copy of Port.vi a unique VISA reference and a unique "Start/Stop" [boolean] notifier - let all the copies share the same Quit Occurance.
In Main, have one event case for each of your stop buttons. When a button is pressed, send the appropriate Start/Stop notifier!
... of course you could accomplish the same thing with four identical loops right in your main diagram, but the more complex the port-handling gets, the easier it will be to manage in one place instead of four.
Cheers!
When they give imbeciles handicap-parking, I won't have so far to walk!

How to acquire data from 2 chs of the same DAQ card at different sampling rate

I am using single DAQ card (either 6013 or 6014) in my system i want to acquire data from 2 (or more) channels with following requirements
1. sampling rate of each channel should be independant of each other (say one is 20 Hz and other is 15 kHz)
2. data from all the channels should be acquired simultaneously.
3. coding must be done using DAQmx VIs
I have tried out following things
1. I created separate task for each channel: i found out that two tasks can not run simultaneously even though the channels are different
2. I tried out single task with two channels included in it. and i used 'channels to Read' property to determine from which ch. i want to acquire data: this method works fine if the sampling rates are same. but if i change the sampling rate of one channel it gets reflected in other channels as well.
can somebody help me out to solve this problem.
i will appreciate if somebody can post the sample code as my deadline is approaching

Data load failed while loading data from one DSO to another DSO..

Hi,
On SID generation data load failed while loading data from Source DSO to Target DSO.
Following are the error which is occuuring--
Value "External Ref # 2421-0625511EXP " (HEX 450078007400650072006E0061006C0020005200650066
Error when assigning SID: Action VAL_SID_CONVERT, InfoObject 0BBP
So, i'm not getting WHY in one DSO i.e Source it got successful but in another DSO i.e. Target its got failed??
While analyzing all i check that SIDs Generation upon Activation is ckecked in source DSO but not in Target DSO..so it is reason its got failed??
Please explain..
Thanks,
Sneha

Hi,
I hope your data flow has been designed in such a way where the 1st DSO as a staging Device and all transformation rules and routine are maintained in between 1st to 2nd dso and sid generation upon activation maintained in 2nd DSO. By doing so you will be getting your data 1st DSO same as your source system data since you are not doing any transformation rules and routine etc.. which helps to avoid data load failure.
Please analyze the following
Have you loaded masterdata before transaction data ... if no please do it first
go to the property of first dso and check whether there maintained sid generation up on activation (it may not be maintained I guess)
Goto the property of 2nd Dso and check whether there maintained sid generation up on activation (It may be maintained I hope)
this may be the reason.
Also check whether there is any special char involvement in your transaction data (even lower case letter)
Regards

"Transfer structure does not exist" while deleting data from a DSO

Hello experts,
while deleting data from a DSO I get the following messages:
@5B\QInformation@     Database table /BIC/AAKIVO1400 was deleted and recreated
@5C\QError@     Transfer structure does not exist
When I try it twice process works without any problems. I get then the following msgs:
@5B\QInformation@     InfoCube / DataStore object "AKIVO14" contains no data (yet)
@5B\QInformation@     Database table /BIC/AAKIVO1400 was deleted and recreated
So I think the first deletion works but ended with errors. What could be the reason?

Please check if data from new and chage log table is also deleted.
For the error message : Do you have 3.5 flow ? Check your transfer structure , if it is active and then again try to right click and delete data from DSO.

Acquiring data from instruments and wiring it to a while loop

Hello,
I am very new to labVIEW and was thrown into a project. Essentially what I am trying to accomplish is to acquire data from my four sensors and use that data to compute drag. In order to compute the drag, an initial guess at what the drag is must be given and then calculations are carried out in a while loop that converges on a solution once the difference between the current drag output and the previous drag estimate falls below a certain percentage. I am continuously acquiring data so I need some sort of way to incoporate a timer to allow time for the while loop to converge and then output the drag value. Right now I am generating a signal since I do not have the sensors hooked up and labVIEW will not let me connect the signal generator to the while loop and gives me an error that I have connected two terminals of different types.
If I could figure out how to wire my DAQ assistants to the while loop I could figure everything else out
Thank You,
Ellen

Hi Ellen,
I might need a little more information before I can help you. How are you simulating your signals? If you're using the DAQ assistant express VI, are you simulating hardware in MAX? Or are you using the simulate signal express VI?
Alos, what VIs or functions do you have inside the while loop that you are trying to connect to?
Perhaps posting a screenshot would be useful. I'm sure we will be able to solve your problem.
Here is a help page that you might find useful.

Exception thrown while trying to acquire data from Profile Data Control

I created a new WebCenter Portal Application (with JDeveloper 11.1.1.4).
Then tried to acquire data from Profile Data Control through getProfile().WCUserProfile to create a read-only form with profile data.
After deploying (to internal WLS) and running I got a popup saying:
*Exception [EclipseLink-7060] (Eclipse Persistence Services - 2.1.2.v20101104-r8475): org.eclipse.persistence.exceptions.ValidationException Exception*
Description: Cannot acquire data source [java:comp/env/jdbc/WebCenterDS].

Resolved 'jdbc'; remaining name 'webcenter/CustomPortalDS']; Link Remaining Name: 'jdbc/webcenter/CustomPortalDS'
The question is how can I create such a data source to acquire data needed?

Hi, there's two ways, in both ways you need use the user <PRE>_WEBCENTER that RCU create.
1 - You can go in your console and create de dataSource, as Yannick sad. You can use your production database if you want get some more real tests, or you can get some develope database and run RCU. You can copy the configuration from you WLS server that are installed webcenter to make this easy.
2 - In develop mode you can just create a database connection name "WebCenter", just like sad here:

Acquiring data from DAQ

Please, I am writing a VI to acquire data from one micrometer (like a quad encoder) and a quad encoder for the position. How can I store data coming from the micrometer ( read by a channel of a multifunction DAQ ) in an array of 5000 positions ( one for each millimeter of movement ) ? Thanks

First initialize a 5000 element array (Not a Number (NaN) data suggested), then run your acquisition loop and replace the array with the acquired data at index position. This is much more efficient than building the array progressively. Use a feedback node to store the array during execution. Look at the attached vi.
Note that this works with single data points. If you were recording multiple data at each loop iteration, then you would have to calculate the replace position by multiplying the loop iondex with the data length.
Hope this helps !

Problem in loading data from one DSO to onother DSO in BI7

Hi
Iam loading data from one DSO to onother, After executing DTP Iam getting error message as "Aggregation NOP not allowed on DB (key figure 0DSCT_DAYS1) ", Here 0DSCT_DAYS1 is the keyfigure aggragation type is "NOP" , exception aggregation is " No aggregation(X if more than one value unique to 0 occurs)"
Please kindly give me solution .
Radha Krishna

We had this issue in our project. It mainly arises when you have written start routine in transformation. At start routine level it can not aggregate the fields for which NOP is set & that's why it throws an error.
Please check the load by removing the start routine. If it works then introduce a data target in between which has exactly same structure as previous data target except the fields with NOP aggregation.

How to acquire data from the memory of multimeter

I am a beginner of Labview. I don't know how to acquire data from the memory of multimeter.
I read some examples about DAQ, but it seems not similar to my case. I can't use DAQ in my computer, as I don't have DAQ board.
Could anybody give me some guide? Similar examples would be great.

Confirm that you have the VISA Run Time Engine on the target machine. If you do not have it installed, you can install the VISA Run Time Engine from ni.com.

Acquire data from oscilloscope DPO2024

I am trying to acquire data from oscilloscope DPO2024 using labview. I am able to do so, but my vi file works only for channel 1. Other than channel 1, it do not work and instead, it changes the setting of oscilloscope as well. Find the vi files attached.
Any help is much appreciated.

1. You only need to initialize the scope once. You not need to branch the VISA Resource wire. Call the Initialize, Setup Channel 1, and then Setup Channel 2 all chained together.
2. Use Build Array to create your array of channels. The Merge Signals is a completely backwards way to do it.
3. You only need to close the instrument once.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Merge data from multiple DSO's into one DSO

Hi,
I want to transfer data from 4 different 1st level DSO's to a single 2nd level DSO. I have 8 key fields in the 2nd level DSO, 2 from each 1st Level DSO. The 1st level DSO's are Sales Orders, Deliveries, Sales Invoices and Financial Invoices. The goal of this is to create a 2nd level DSO for Sales KPI so the data has to be consolidated so it's not supposed to contain all the records from each DSO but it has to consolidate them somehow.
example:
R/3     Order           0000012901     item 10          created              05/08/2008

     Invoice          0090036871     item 10          created          05/08/2008

Hi,
I think your second level DSO should have only 2 key fields: Sales Order no and Item. The other fields will get update in this case. Hope this helps.

Acquiring data from all the analog channels of NI-3202 NODE using a single sensor

Hi all,
I would like to know that can i be able to get the data from all the four analog channels of NI-WSN node 3202(analog input node) connecting only single sensor on the analog input and connecting all the remaining analog inputs using wires and also shorting the ground pins corresponding to each analog input pin.
By configuring the each channels like 0.5 sec delay for every analog channels to acquire data. can we get the sensor data from all the channels by doing this. basically here i am trying to increase the minimum sampling rate of the ni-wsn NODE 3202 which is 1s.
I this approach is correct or we cannot do this.
Thanks

Stefan,
In terms of differential and RSE, channels 0-8 should default to differential when using test panels. Differential needs two input channels to function correctly and these channels must be spread apart by 8 channels. (i.e channels 0 and 7 are a differential pair) Channel 13, on the other hand, will default to rse if chosen as the reading channel because there does not exist another channel that is eight away. I am not quiet sure if the virtual channels will default channel 5 into being differential but I will check into it. If it is differential as default then you may run into problems since channel 13 is utilized in both strain gauge reads.
"The second question is, if we can also use the "voltage" setting for measuring strain gauges? we did that in the past, using LabView 6.2."
If you are referring to "voltage" as acquiring a signal with custom voltage with exciation then I would reccomend using example in LabVIEW called Acq Wheatstone Bridge Samples (with Calibration). This can be found by navigating to LabVIEW's example finder and expanding Hardware Input and Output>>DAQmx>>Analog Measurements>>Strain.
I have also included some useful links that may provide more insight into the SCC modules as well. Also, what is the excitation voltage and power that your strain gauges are expecting?
