Distorted Output with NI 9263

I am currently working on a project but I have run into a road block.
I cannot get my DAQ to output a clean signal I and I am sure what I am doing wrong. I am using a NI 9263 DAQ with a NI cDAQ 9172 chassis. I made a very simple vi to test the hardware but the results are not very good, and even when using a 96kS/s sampling rate to generate a 1kHz signal produces rather poor results.
I have included the vi I used to test the hardware and pictures of the output. Any help would be greatly appreciated.

You increase the number of samples you're using on the DAQ assistant and the wave generator, it's a pretty low value, so it's probably unable to create the waveform appropiately.

MacBook core duo Sept. 2006 - the audio is a mystery. Any analogue out has bass boost with bass distortion. With digital out, by USB or Airport Express Airtunes, the frequency response is normal. Somewhere, Apple put in an analogue bass boost.. why?!

Since new, my Macbook core duo has sent all audio to all analogue outputs with frequency distortion. Some physical hardware or firmware in the analogue section adds a bass boost to the frequency response of the audio.... And, this boost adds bass frequency distortion to most, if not all, of the audio analogue output.
This happens for all audio sources, players, iTunes, videos, streaming audio/video, movies... any sound source available to the Macbook. No-one with whom I have talked about this problem, has ever heard of it. Not elegant ideas for reducing it are to use equalisers on players and iTunes. iTunes even has a preprogrammed "bass reduce" on its equaliser, as if it knows already that this inherent bass boost "feature" has been built into the Macbook, and cannot be defeated by the user.
The digital audio is of sufficiently high quality to play well on a very good to excellent sound-system; so, it's a shame someone has mucked around with the frequency response of the analogue conversion, by designing the frequency distortion right into the computer. This motherboard, (which includes the sound-section), has been replaced, along with the speakers, and everything sounds exactly the same as it was before.
To receive a flat frequency response and no frequency distortion, I listen on one receiver using Airtunes, (it doesn't matter whether or not the analogue or digital output jack is wired analogue or connected via optical cable.... the freq. response is flat); and I listen on a high-end stereo system using an USB output port to an A/D converter, passing the analogue result using long patch-cords connected to the "line-in" jacks of the stereo. The bummer is that most of my audio sources are not derived from iTunes... hence, I cannot use Airtunes with Airport express for them. I've tried using "Airfoil" without luck. The sound becomes distorted with sibilance and other frequency anomalies.
Question: has anyone else discovered this sound imperfection in any Mac product? And, does anyone know if Apple is aware of it? Finally, has anyone found an Apple fix for the problem; or, at least, come up with better solutions than I have?
Thanks heaps for any impute and answers you may supply!! junadowns

Excel output (with graphics)

Hello,
I am using Oracle reports 10g 1.2.0 version.
We need to generate oracle reports in Excel format ("real" Excel, not delimited text) with tabular data and
also graphics.
I used desformat=spreasheet. But is is giving only one worksheet.
I've found the "Output to Excel with Oracle9i Reports"
demo but the Excel template in the demo is very simple and doesn't have graphics.
Then I've found the following:
http://otn.oracle.com/products/reports/htdocs/getstart/examples/excel_output/result/excel.jpg
a) The above site has excel output with multiple worksheets.
which is similar to what we need but I wasn't able to find related source (excel_emp.jsp).
b) Using jsp if we can ahieve multiple worksheets with grapahics, please provide us examples.
c) http://www.oracle.com/technology/products/reports/htdocs/getstart/demonstrations/excel/index.html --This site is not working to find the demo.
Could you please help me in this?
Thank you for any help.

carla,
the example you mentioned uses the JSP web source that is only available in oracle9i reports.
in theory you can create any excel output. it is just a matter of creating the template and then adding the reports tags to populate it with data.
you could then use reports' URL engine to produce files from this output.
there are certainly ways to do it, but they are only available in oracle9i reports (9.0.2 and higher)

Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format

Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format. Siebel wants to send the data as xml to BI but not sure of the BI capabilities on giving WSDL embedded with XSD (input is a hierarchical)

Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.

Digital Output With Timer (Simulation)

Hello everyone, I just learned how to make LabVIEW program a week ago. I try to make a simulation of Digital Output by LabVIEW (my attachment). In this simulation I have a slider as an input (0-10 V), two numeric control (upper limit and bottom limit), a waveform chart that plot those 3 value, and two boolean LED (P0.0 and P0.1) as an indicator. In this simulation you can fill any number (between 0-10) in the numeric control as a limit for your slider input. If the input from a slider exceed those upper and bottom limit then the boolean LED will turn on, P0.0 if exceed upper limit and P0.1 if exceed bottom limit. The problem is I don't know how to make timer for those boolean LED. As example:
1) Make an input from slider,
2) If input (1) exceed the upper limit,P0.0 will turn on for 5 second,then turn of for 10 second,
3) If in that 10 second you change the input back to normal (between upper and bottom limit) then P0.0 will stay turn of until the input from slider exceed the upper limit again,
4)If in that 10 second you didn't change the input (stay exceed the upper limit) then P0.0 will repeat the process (2) until you the input from slider back to normal.
(Same process for input that exceed the bottom limit).
Can you help me to make this timer? Thank You (I'm sorry I made a double post):newbie
Regards
Juventom

Digital Output With Timer.vi ‏16 KB

Hello Juventom,
As I understand it you want to be continuously checking the value of the sliding bar and comparing that to the upper and lower limit controls whilest also chaning the LED booleans to true for 5 seconds then false for 10 seconds if the sliding bar value is outside of the limits.
To do this you would probably be best using a parallel loop design, where you have 3 while loops in place of the one you have currently. Each one of these while loops would be responsible for a part of your program (e.g. the top one would display your values on the graph and the second one who check the sliding bar value against the upper limit and then turn on the LED, etc)
I've found this tutorial about multiple loop programs and I think you should look at the section entitled "Parallel Execution"
http://zone.ni.com/devzone/cda/tut/p/id/3749
This way you can use normal delay VIs but when they run they only pause that loop rather than the whole program.
Please let me know how you get on with this, and ask me if you need further help.

PDF Output with javadoc

Somebody once asked how to create PDF output with javadoc, so here's some work in progress:
I am currently creating a PDF doclet which creates directly PDF output from javadoc. It's still in alpha stage, because it does not yet create an index or navigation frame (which is mandatory for the PDF to be useful), and most HTML tags are not yet interpreted. But that's gonna improve over the next few weeks.
http://sourceforge.net/projects/pdfdoclet
Bye,

Hai Marcel,
How to run this pdfdoclet?
I tried like:
javadoc -doclet com.tarsec.javadoc.pdfdoclet.PDFDoclet -docletpath d:\For_PDF_Doc\itext-0.92.jar;d:\For_PDF_Doc\pdfdoclet.jar *.java
And the result is:

How to replace a "notfound" output with a null value?

hi,
I'm just getting a output of "Rows Notfound" for a script..
instead of this , i just need to show the output with a record as null value or some value..
do we have any option to use this in oracle..

Apart from capturing with an exception in PL/SQL code, if you're wanting something in a script as pure SQL, you'd have to generate an additional row and only select that where no data is found e.g...
SQL> ed
Wrote file afiedt.buf
1 select ename from emp where ename = 'FRED'
2 union all
3* select 'No Data' from dual where not exists (select * from emp where ename = 'FRED')
SQL> /
ENAME
No Data
SQL>Of course this does effectively double-up on the queries being executed, so if you're dealing with a heavily complex query, it may be best just just have the regular exception come out, but then this will also depend on your actual requirements and why you want to do this in the first place.

Formatted HTML output with Spry regions - is it possible?

I have recently begun using the XML export extension in
conjunction with an Access database to output dynamic data into a
page with a Spry master/detail setup. So far, my simple example is
going great, but I've run into a snag that I need some help with.
To explain what I'm doing - it's a simple article page with
the list of articles on the left with the title and date and the
article title and full contents on the right hand side. So far it's
all working very well, updating in real time when I click an
article title on the left. The problem is the output with this one
field which stores not only text, but also HTML formatting that is
generated by a wysiwyg editor used on the article creation side of
this little app. This HTML formatted content is the article body
and is stored in a field named the same - "body". With traditional
ASP, the HTML formatting displays as expected and all is well, but
with Spry, it doesn't output formatted HTML, but instead shows the
content and HTML code together as text. How can I get this one
field ("body") to be output so all the HTML formatting is shown?
This is my simple page example. Click through and you'll see
what I mean.
http://www.shoestodyefor.com/ajax.asp
Here's the section of code in question regarding the output
on that right hand panel where the body is displayed for each
article:
<div spry:detailregion="ds1">
{title}<br />
{entryDate}<br />
<br />
{body}
/div>
Is it possible to have that {body} section shown so the
dynamically created HTML code from the wysiwyg editor is displayed
correctly?

The version of Spry that ships with Dreamweaver CS3 (Spry
1.4) doesn't
support the type of output created by the XML Export
extension.
This issue has been corrected in Spry 1.5, but no plans have
been made
public for integrating Spry 1.5 into Dreamweaver CS3. You
would need to
download Spry 1.5 from
http://labs.adobe.com/technologies/spry/.

Regarding ALV outputs ( with layout variants)

Hi,
I have a problem where in an ALV report when it is executed with a variant (there is one layout parameter in the screen which is also filled. This layout is set with a filter),
displays the output. But the displayed output doesn't filter the output as per the required criteria set in the layout filter.
When I execute the report with the same variant but now if I select the layout by pressing F4 on the layout field and select the same layout as earlier (which is having the filter criteria), now it displays the output as per the required criteria set in the filter.
I don't understand why if I execute the report with a variant with the layout value also filled, it is not able to give the required output as per the filter criteria set for the layout.
When the report is executed with the same variant but the layout value selected from F4, it dispalys the correct output with the filter criteria set for the layout.
In general, I mean why the program is not able to load the layout with filter when it is called from a variant?
Regards,
Rajesh

It depends on your Layout, How you saved it .
And one more question are you passing the layout parameter and Filter parameter to the Function module

Billing output with Header & Item data fields

Hello Friends,
I liked to create new access for Billing output with Sales Orgn/Bill to party(Billing Header data) & Material number (Item data).
I tried but system not recognizing the field Material number from billing item level.
Please guide me how to add Material number for item level with other fields form Header for creating new Output access.
kindly do the needful.
regards,
Nitin M.Pawar

Dear Nithin,
In the output determination for billing documents, click on maintain condition tables,
select 'Field catalog: Messages for billing documents'
new entries and enter MATNR.
However after this you will have to get the help of ABAP i suppose (for making this new field accessible for creating condition table).
Thanks & Regards,

mpv doesn't crash, it just falls back to software decoding and gives me a grey screen when it's not fullscreen, and when it's fullscreen it tears a lot and flashes random grey stripes everywhere - sound still works fine. Any ideas on what can be at fault here? The only video output that gives me an OK image without tearing or anything else is x11, but it's really slow.

Thanks, now VA-API at least gives me an output - but the video just flashes in fullscreen. I think another thing to notice here is that the video only plays correctly (gives me an output), if I play it on monitor 1 (I use three monitors) - but I can't get rid of the screen flashing.
EDIT: Fullscreen only flashes when I use mpv, with smplayer (+mpv) it works ok - but it lags from time to time. mplayer-vaapi won't give me a smooth playback either with -vo and -va as vaapi, and the screen also flashes when I'm using it.
Any idea on what's wrong? Is it my use of three monitors? This is really, really annoying.
