Generating Constant Source for Channel Gain Measurement

I need a contant source say a DC level which shall I transmit over a channel to get channel gain/ fading over few transmission blocks.
I tried a naive approach of getting a constant by DC_m= m*sin(t)/sint(t) and sin(t)-sin(t) +m
through follwing design.
Though I can see a constant DC in waveform_graph 3 but when I receive the data from RX port of USRP RIO, which I expected to be a faded DC value, I am getting a sign wave whose frequency is dependent on the tone frequency of the Sin wave generator.
I cannot explain this!!
My purpose if to get channel gain between RX-TX pair and TX-Eavedropper pair. Do I need to implement dedicated channel sounder based on PN sequqnece correlator? or this approach of H_ab= Y/X shall work. I negated X as it would need perfect synchronization between RX-TX pair for channel gain estimation.
Any suugestion on the anomaly? Or suggestion on implementing channel gain measurement using Comm suite.

Hello Wired_,
Can you please provide me with a little more information on how you are recording in the TX data? How are you demodulating the signal? Why are you expecting it to be a faded DC value? Which sine wave generator are you referring too? The carrier frequency or the waveform generator VI in LabVIEW?
I would expect the output of the TX to be the carrier frequency tone, with an amplitude dependent on the DC level.
If you have hardware specific questions, I recommend posting them to the SDR forum.

Generating a constant source for Channel gain/fading estimation

I am using Labview Communication Design suite for programming USRP RIO.
I want to measure channel gain between RX-TX pair for which I plan to send a stream of 1111111 and see the received envelope( without modulating for now).
Since such source for Sin wave was available I thought of generating 1111 stream using 1= sin(m)/sin(m) as per follwing design or 1= sin(m)-sin(m) +1
The issue is though I can see that the waveform entering USRP as data to be streamed is a DC level but at reception side I am getting a sin wave!!
for TX side being:-
Receiver USRP should actually receive a faded random channel for transmitted sequence of 111111! I cannot explain the behaviour!
Even the frequency of Sin wave recived varies with the amplitude of the DC multiplier!
Please help explain the situation.

Generating data source for a planning area

Hi all,
I have a problem when generating a datasource for a planning area as it gives the following logs.
Activate table /1APO/EXT_STRUXXXXX
Tabble 1APO/EXT_STRUXXXXX was activated with warnings
and the data source is not being activated.
I have also created an entry in the table /SAPAPO/TSAREAEX and tried to activate the datasource for the planning area ,it is saying the datasource already exists.
Can anyone give me a straight solution for this.
thnks in advance.

Hi Satish,
After you generate the datasource, go to transaction /n/sapapo/sdp_extr and try doing a check on this datasource. If you still get those warning/error messages, try the Repair datasource option and see if it fixes the issue. In RSA1, replicate this datasource and then try activating it there and see if it works. Don't create an entry in the table /SAPAPO/TSAREAEX, as this is not a standard recommended way of doing it. Good luck
Regards,
Mohammed.

Line Items Data Source for General Ledger

Hello everybody,
I'm trying to generate a Data Source for Line Items (new General Ledger) in transaction FAGLBW03. When I generated a Total Record-Data Source, everything was done correctly. When I try to generate a Line Item-Data Source, I receive following error message: "Extractors for general ledger documents are not yet supported". I was looking for any SAP notes that would explain this issue, but I couldn't find anything.
Could you please tell me how can I generate Data Source for Line Items? Add some SP, use some another transaction, ...?
Thank you for any help

Generate xml source file for Oracle Order Capture Print Quote

Hi,
I am new to xml and need to work on creating templates for Print Quote.
I am trying to generate the xml source file for which I enabled the report in system administrator and set the output to XML and assigned to Quoting Reports responsiblity. I then assigned XML Report Publisher to the same responsiblity.
I ran the report (Print Quote) and then I am trying to run the XML Report Publisher but I cannot get the request id in the list of values.
I am able to generate xml source file for other reports like Printed Purchase Order etc.,
The view output for the (Print Quote) report is as follows:
<?xml version="1.0" ?>
- 
<ASOPQTER />
How do I get the xml source file? Or are there seeded templates that I can use to create more templates? Any help would be appreciated. Thanks Ravi

Hi, I am in the same position - did this issue ever ger resolved by anyone. I have done a few XMLP reports successfully now using the Word add-in, but customising the Quote output differs from other standard reports.
If you look at the data definition for Quote it is a 'dummy' definition and has no XML file attached. Does anyone know how I can get the XML format for the report output?
Also the template uses XSL-FO ?!?!?! rather than RTF - not sure how to work with this, the Oracle docs are not very helpful in this regard either.
Has anyone successfully managed to customise the Quote print report? Many thanks,
Roger

Unable to generate "Export data source" for Master data infoobject

Hi Gurus,
I'm in BW 3.5
I need to generate "Export data source" for a master data info object.
I followed below steps:
I ticked the checkbox "Characterist. is export data source" in the master data Info object maintenance screen.
In the Infosource area, for the desired Infoobject --> Right click --> Generate export datasource --> a dialog box displays saying "The generation of DataSource was successful"
Problem:
Even after refreshing, etc.. I couldn't find the generated datasource 8**** for the above master data. I also tried to replicate the datasource from the myself source system, but couldn't find it even there. I don't know where the generated export data source is hiding ???
Could anyone please help ????
Thanks,
Venkat

Hi Venkat,
I guess that after creating an export datasource for infoobject this DS should appear in the RSA1-Source systems - MYSELF - datasource overview (with name starting with 8). Since it's a datamart, it should appear also as system generated infosource. And in this case you would be able to assign in URs of data target the appropriate infosource (make sure that in Infoproviders tab of RSA1 you have inserted your infoobject as a data target).
However, there are some bugs related to export data source. CHeck if you see you export data source in RSA6.
If you don't see it - consider applying OSS Note #816892 - "30BSP26: Export DS for master data is not generated".
Note #876845 - "30BSP29: InfoObject change: Export DataSource not adjusted" is also may be useful.

Need urgent help to generate SPL Data Sources for Line Items

Hi All,
I am trying to extract the Special Purpose Ledger Data from R/3 into BW. To do this, I am following the steps to generate the Data Sources for Totals table and Lien Items Table.
Using Transaction BW01 and BW03 on the R/3 side, I am able to generate the Totals Record-DataSource successfully.
But I am not able to generate the Line Items-DataSource. I am using the same procedure.
Can someone please help me or point me in the right direction. Are there any other settings I need to make to generate the Line Items-DataSource. Interestingly, I am able to generate the Line Items-DataSource for some other old ledgers in the System like ZZ and ZX. But I need the Line Items-DataSource from a ledger called ZP for which I am having trouble.
I would greatly appreciate if someone can get back to me ASAP.

During BW01, The Generate extract structure is fine for both Total and Line Item Table.The issue is when we run tcode bw03 where you assign the datasource to a ledger.
Here, I can assign only for the Total Records data source and NOT for the Line Items-DataSource.
I hope I could explain the issue. Looking forward for some advice.

Urgent: How to generate lo source images for slideshows?

Hi everyone,
I'm trying to generate low source images for my website, to reduce frustration for viewers downloading larger image files. In the past this has been easy to do one at a time, however I've got some slideshows on my website that are quite large and I'd like to be able to do the same for them. However, the low source auto generate button just generates a low source for the first image (the root source file of the slideshow) and not for any of the others. Is there a way to overcome this? Will it muck up the flow of the slideshow to have the low source images in the same folder with them?
Thank you
CJ

Actually, you are right - the source for the codecs can be found in the

there is
a difference between the classes in the war, the classes in the client jar

It seems for the Data Transfer Objects, it makes a difference whether you

PXI 2527 & PXI 4071 -Questions about EMF considerations for high accuracy measurements and EMF calibration schemes?

Hi!
I need to perform an in-depth analysis of the overall system accuracy for a proposed system. I'm well underway using the extensive documentation in the start-menu National Instruments\NI-DMM\ and ..\NI-Switch\ Documenation folders...
While typing the question, I think I partially answered myself while cross-referencing NI documents... However a couple of questions remain:
If I connect a DMM to a 2 by X arranged switch/mux, each DMM probe will see twice the listed internal "Differential thermal EMF" at a typical value of 2.5uV and a max value of less than 12uV (per relay). So the total effect on the DMM uncertainty caused by the switch EMF would be 2*2.5uV = 5uV? Or should these be added as RSS: = sqrt(2.5^2+2.5^2) since you can not know if the two relays have the same emf?
Is there anything that can be done to characterize or account for this EMF (software cal, etc?)?
For example, assuming the following:
* Instruments and standards are powered on for several hours to allow thermal stability inside of the rack and enclosures
* temperature in room outside of rack is constant
Is there a reliable way of measureing/zeroing the effect of system emf? Could this be done by applying a high quality, low emf short at the point where the DUT would normally be located, followed by a series of long-aperture voltage average measurements at the lowest DMM range, where the end result (say (+)8.9....uV) could be taken as a system calibration constant accurate to the spec's of the DMM?
What would the accuracy of the 4071 DMM be, can I calculate it as follows, using 8.9uV +-700.16nV using 90 days and 8.9uV +- 700.16nV + 150nV due to "Additional noise error" assuming integration time of 1 (aperture) for ease of reading the chart, and a multiplier of 15 for the 100mV range. (Is this equivalent to averaging a reading of 1 aperture 100 times?)
So, given the above assumptions, would it be correct to say that I could characterize the system EMF to within 8.5uV+- [700.16nV (DMM cal data) + 0.025ppm*15 (RMS noise, assuming aperture time of 100*100ms = 10s)] = +-[700.16nV+37.5nV] = +- 737.66nV? Or should the ppm accuracy uncertainties be RSS as such: 8.5uV +- sqrt[700.16nV^2 + 37.5nV^2] = 8.5uV +-701.16nV??
As evident by my above line of thought, I am not at all sure how to properly sum the uncertainties (I think you always do RSS for uncertainties from different sources?) and more importantly, how to read and use the graph/table in the NI 4071 Specifications.pdf on page 3. What exactly does it entail to have an integration time larger than 1? Should I adjust the aperture time or would it be more accurate to just leave aperture at default (100ms for current range) and just average multiple readings, say average 10 to get a 10x aperture equivalent?
The below text includes what was going to be the post until I think I answered myself. I left it in as it is relevant to the problem above and includes what I hope to be correct statements. If you are tired of reading now, just stop, if you are bored, feel free to comment on the below section as well.
The problem I have is one of fully understanding part of this documenation. In particular, since a relay consists of (at least) 2 dissimilar metal junctions (as mentioned in the NI Switch help\Fundamentals\General Switching Considerations\Thermal EMF and Offset Voltage section) and because of the thermo-couple effect (Seebeck voltage), it seems that there would be an offset voltage generated inside each of the relays at the point of the junction. It refeers the "Thermocouple Measurements" section (in the same help document) for further details, but this is where my confusion starts to creep up.
In equation (1) it gives the expression for determining E_EMF which for my application is what I care about, I think (see below for details on my application).
What confuses me is this: If my goal is to, as accurately as possible, determine the overall uncertainty in a system consisting of a DMM and a Switch module, do I use the "Differential thermal EMF" as found in the switch data-sheet, or do I need to try and estimate temperatures in the switch and use the equation?
*MY answer to my own question:
By carefully re-reading the example in the thermocouple section of the switch, I realized that they calculate 2 EMF's, one for the internal switch, calculated as 2.5uV (given in the spec sheet of the switch as the typical value) and one for the actual thermocouple. I say actual, because I think my initial confusion stems from the fact that the documenation talks about the relay/switch junctions as thermocouples in one section, and then talks about an external "probe" thermocouple in the next and I got them confused.
As such, if I can ensure low temperatures inside the switch at the location of the junctions (by adequate ventilation and powering down latching relays), I should be able to use 2.5uV as my EMF from the switch module, or to be conservative, <12uV max (from data sheet of 2527 again).
I guess now I have a hard time believeing the 2.5uV typical value listed.. They say the junctions in the relays are typically an iron-nickel alloy against a copper-alloy. Well, those combinations are not explicitly listed in the documenation table for Seebeck coefficients, but even a very small value, like 0.3uV/C adds up to 7.5uV at 25degC. I'm thinking maybe the table values in the NI documentation reffers to the Seebeck values at 25C?

Seebeck EMV needs temperature gradients , in your relays you hopefully have low temperature gradients ... however in a switching contact you can have all kind diffusions and 'funny' effects, keeping them on same temperature is the best you can do.
Since you work with a multiplexer and with TCs, you need a good Cold junction ( for serious calibrations at 0°C ) and there is the good place for your short cut to measure the zero EMV. Another good test is loop the 'hot junction' back to the cold junction and observe the residual EMV. Touching (or heating/cooling) the TC loop gives another number for the uncertainty calculation: the inhomogeneous material of the TC itself..

Hi,
With your first xml you can print like
EMP1
71000, Sample, 01-Jan-2010
72000, Sample, 01-Feb-2010
73000, Sample, 01-March-2010While creating the RTF template you can use the Group by option.
<?for-each-group:ROW;./columnname> then print the column name
<?columnname?>
--Then your table format
71000, Sample, 01-Jan-2010
72000, Sample, 01-Feb-2010
73000, Sample, 01-March-2010
<?end for-each-group?>
Thanks.

Creating a DBI Report with a Generated Data Source

Hi all,
I am on a customer site helping them to implement DBI.
We're using DBI Designer to create some Custom Reports.
We're interested in using Generated Data Sources in order to simplify handling of the complex Time Hierarchies implemented as standard within DBI (eg Rolling 30 days, Compare To Periods etc).
I've read the Metalink Note on how this should be achieved.
(Note 363529.1)
Unfortunately, we seem to be in a Catch 22 situation.
The note states that we need to have BSC v5.3 (or later !) installed.
The latest patch version of OBSC we can find is 5100729 (BSC.I.delta.12).
Our belief is that BSC.I is version 5.2 (incidentally, why do we have two naming/numbering "conventions" ?)
So two questions :
can we use generated data sources now, or do we have to wait for BSC 5.3 ?
when will BSC 5.3 be generally available ? (our customer uses HP/UX)
thanks for any input
Mike

Hi All,
I am a newbie to DBI. Currently going through the documents DBI for Finanicials
and Payable.
We have to develope custom reports for Payables and Financials intelligence based on Oracle Reports . I would like to know if its possible or not because I read a thread on Forum ("How do you make a copy of an existing DBI report? ") in which it mentions that it is not possible to edit a standard report.
And if it is possible how to go for that ?
Thanks in advance,
Anant.

Trying to change the data source for a Crystal Report.

The method below represents my best attempt to programatically change the data source of a Crystal Report. The goal is to have a routine that will update the data source for reports after they have been distributed to production servers. So far I have not been successful in saving the report back to the CMS. No exceptions are thrown, but when I view the Database Configuration of the report in the CMC nothing has changed.


Am I missing a step, or is there another way to accomplish this?


Thank you.

Justin,

Thank you for the reply. Time constraints have not allowed me to post back to this tread
till now. I will try your suggestion. My assumption is that Save the report back to the
info store refers to IInfoStore.commit(IInfoObjects).


I'm afraid that I do not understand why I don't want to change the report client document,
or why successfully exporting the report with the new login/password is not what I
want to do. Any explanation on that statement would be appreciated.


I did find a way to accomplish my goal. It involved adding the SSOKEY property to the
logon property bag. Below you'll see my revised code which modifies the report logon and
server. I have no idea what
this does, and SAP support has not been able to tell me why it works. However, what I
discovered is that if I changed the report option, Database Configuration -> When
viewing report:, in the CMS to Use same database logon as when report
is run from Prompt the user for database logon, then the
SSOKEY property had been added to the logon property bag having an empty string as its
value. This allowed me to successfullyupdate and save the modified logon back to the CMS.


So I took a chance and added code to always add the SSOKEY property with an empty string
as its value, and I could then successfully modify and save the report's logon info
and server. Again, I don't know what this means, but it has worked so far. If anyone has
some insight or comments, either are welcome. Thank you in advance.
