ECG Analyzer Help

Hello,
I am doing an assignment on an ECG analyzer. First, I have "generated" an ECG signal by just making it read from data points because I figured this would be the easiest transition for when I have to actually test my program with actual hardware later.I am pretty much just looping the same signal over and over, would it be better to make my own signal?
My question is, I am having problems with my filter when I am using my datapoints for the waveform. The filtered signal doesn't look too clean. Is it because I am using a butterworth filter? I am not sure which frequency and order I should be using. Also, does anyone have any suggestions on using a heartbeat detector? I figure that I can use the peak to peak detector, and then feed that into a program that will then do the analysis based on the number of beats per minute. Please advise...attached is my current VI with the two data points that I am using. Thanks.
Also, is the way that I am reading in my data efficient? I sometimes find it difficult to read certain datapoints into my program.

Go to this post http://forums.ni.com/ni/board/message?board.id=170&message.id=412111&query.id=9546898#M412111 and find the accepted solution. Follow the instructions. Since you use LAbview 8.5, you must change the 8.6 part of the install directory to fit your Labview version. Download the VI I have posted here. And insert the ECG simulator as shown in the picture inside the VI I have posted here. You can configure the Express VI by double clicking on it
Good luck
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Jdeveloper 11g http analyzer help

Hi ,
I am trying to run a web service. I would want to test the wed application in the http analyzer, but when i run test web service.I have my http analyzer running, when i click "create new request" the http analyzer window opens up , but i dont see any url or wsdl url nor i can post any request to test the web service. No parameters tab is shown. I am not able to understand what settings are required to the http analyser up and running to test the web service.
Any idea people. ??
Thanks

HTTP Analyzer help for web service client in 11g

I am using jDev 11.1.1.3.0 to build a web service client (proxy) to a potential vendor's web service. I've used the Http Analyzer before but I'm having trouble configuring it for a WS proxy. I just want to see the SOAP stream between my client and the web service. I used the Web Service Proxy wizard to create the Java code, but the web service provider has kept some of the contract in the WSDL private so that I had to manually generate the meat and potatoes of the Java code. I need to be able to see the SOAP my Java code is sending.
I have tried to configure the Http Analyzer to listen on it's own localhost and port with a forward rule to forward the request to the real WS, but I cannot figure out how to get the client to send it's requests to localhost instead of the actual WS.
Actually, I did figure it out, but then the request fails as it apparently tries to connect to the real WSDL before actually sending the request and cannot find a WSDL at the localhost URL. Here's the error:
Exception in thread "main" javax.xml.ws.WebServiceException: {http://localhost:8099}CatalogRequest is not a valid service. Valid services are: {http://[actual URL here]}CatalogRequest
at com.sun.xml.ws.client.WSServiceDelegate.<init>(WSServiceDelegate.java:249)
I have also tried to configure the Http Analyzer to somehow 'sniff' the actual URL by listening on the actual URL and port, but either I cannot get the Analyzer to see the request or it fails because the Analyzer is using the same port the request is trying to use.
Can someone explain how to configure the Http Analyzer to see the SOAP stream for a Web Client Proxy?

Hi, I'm just using the default setup for HTTP Analyzer and having no problem using it.
Just make sure to run the HTTP Analyzer first before running or starting your app server (Integrated weblogic Server).

Query analyzer help

Hello quick question,
I am trying to get data from a database and two tables into a csv.. I thought i could write a join but i dont see the join between the two tables. How would i do this, the tables are called dbo.card and dbo.person. The database is called wapac. The column
in the dbo.card table that I need is Card Number and that has to match up with First Name, Middle Name, Last Name from the Dbo.person table. Any help would be great. I thought the ID was the connection but it is not.

Can you post the DDL (CREATE TABLE) for the tables?
Usually tables are JOINed on PRIMARY KEY and FOREIGN KEY.
> column in the dbo.card table that I need is Card Number and that has to match up with First Name, Middle Name, Last Name from the Dbo.person table
There must be some sort of mapping between cards and persons.

Hard Abend, Analyze help

One of the border mangers that I work on hard abended this morning. It rapidly went down and then locked the server out. I have seen this before and just wanted to get a second opinion on the matter.
Abend 1 = error code 00000010 Page Fault ( I am thinking this may be the main cause as it occurred a few days back)
Abend 2 = error code 00000000 Page Fault
Abend 3 = error code 00000002 Page Fault
Abend 4 = error code 00000000 Page Fault
Abend 5 = error code 00000000 Page Fault
Abend 6 = error code 00000000 Page Fault
Abend 7 = Missing from the log
Abend 8 = NLM unloaded without deleting all its processes
I am thinking that the proxy is the root of the issue, but i am not sold 100% on it just yet.
Thanks in advance

Database table Analyze

<p>
{color:#339966}Hi,
I have a very basic question.
I want to know what exactly happens in the Database architecture when a table analyze is done by gathering the stats.
How does this analyze helps in performance of queries.

hi,
Table analyze is done to get the internal details for the table like exact space used,exact blocks used,row chaining etc.
optimizer uses these details in creating execution plan for the statements for that table.

Enhanced dictation

What is enhanced dictation used for?

Hello Sybarian,
Thank you for the question. If you select Enhanced Dictation, your Mac converts words to text without sending the information to Apple:
Use Enhanced Dictation
If you use Enhanced Dictation, also known as “Mac-based Dictation,” your Mac converts your words to text without sending any information to Apple. If you select this option, you’re prompted to download the language data your Mac needs for voice recognition. Your text appears as you speak, and you can use the keyboard, mouse, or trackpad to edit as you go.
If you don’t use Enhanced Dictation, your words are sent to Apple servers to be analyzed, helping your Mac understand what you’re saying. This method, also known as “server-based Dictation,” takes advantage of the latest language data.

Good, then we are talking about the same thing when it comes to states. The following defines all the digital logic states our hardware supports:

5600 lowest frequency

Hello
According to NI 5600 downconverts any frequency to 15Mhz(with 20Mhz bandwidth). but specification says 5600 has a range of 9Khz -2.7Ghz. what if the input frequency is 9Khz or lower than 15Mhz. what does it do .does it upconvert the signal to make 15Mhz or what? i have seen a badpass filter in the block diagram of 5600 (not a low pass which always downconverts the signal ) in inital stage of 5600 does this bandpass act as highpass for lower frequencies than 15Mhz . am i right or no
Regards
Madd

Hi Madd,
You're initial thought is correct. Frequencies below the 15 MHz IF output are upconverted. More interestingly however is that the first mixer stage of the PXI-5600, see the block diagram in the NI RF Signal Analyzer Help or NI-5660 Help, always upconverts the signal.
Let's break down the signal chain portion of the block diagram:
1: The Low Pass filter here ensures that the signal we are manipulating has significant power confined to within the 2.7 GHz range of the device.
2 & 3: This first mixer upconverts the signal to an IF frequency, allowing us to spread out the images and harmonics that result. We can then filter this signal to focus in on the pertinent information as well as ensure qualities such as passband flatness.
4. We then downconvert the result from the BPF in step three to another IF frequency.
5. This BPF is the actual filter which sets the 20 MHz bandwidth of the 5600 device. It also allows us to do further conditioning of the signal.
6. The result of step 5 is then downcoverted with this mixer to the IF frequency you mentioned, 15 MHz +/- 10 MHz.
7. A final LPF is used to condition the IF output signal before it is sent on to a digitizer or third party device.
Hopefully this gives you a better impression and understanding of the signal chain.

Create pulse with 6542 card

Hi just wondering if you can create output pulses that are in sync with a clock in signal input (all TTL) with the 6542 PXI card? For example control the pulse width and delay with reference to an input clock signal? If so any examples, thanks.

Hey svt4cobra6,
Do you need the 1 ms pulse to go out on a PFI line? If not, I would recommend using one of the data lines on the 6542 to create your pulse. As smercurio_fc mentioned earlier, you can use the Example Finder, and browse by task, then go to the Hardware Input and Output -> Modular Instruments -> NI-HSDIO (High-Speed Digital I/O) folder. Here is where you can find a lot of examples specific to the HSDIO device you are using. For your application, it sounds like you want to do both generation and acquisition, so check out the folder that says Dynamic Generation and Acquisition. One good one you could use to kind of simulate the device you will eventually hook up is the "Dynamic Generation and Acquisition - Source Synchronous". This example is probably not going to do exactly what you need it to do, but you can get some ideas from it, like how to export a clock with your data, or input a clock from your DUT, and how to use a trigger for when to acquire data.
Now this source synchronous example uses Strobe as the Acq clock, but if you want to generate data based on an external clock, you will probably want to check out the "Dynamic Generation with External Sample Clock" example (found in the Generation -> Non-Scripted folder). If you are basing your pulse off of an external trigger and an external clock, you should check out the Specifications (Start -> Programs -> National Instruments -> NI-HSDIO -> Documentation -> Specifications) of your device for the Delay from trigger to digital data output, to make sure you can account for this if you need to.
For the acquisition of your serial data, that also has a chip enable, you could check out the Dynamic Acquisition Hardware Pause Trigger, if you want to acquire data when your chip enable line is high, and then not acquire (or pause acq) when that line goes low.
Now back to my recommendation for using the data lines as your pulse generator instead of a PFI line, you can use the onboard clock rate, let's say you use the max rate of the 6542, which is 100 MHz, which will generate samples every 10 ns, you can generate 0's until you are ready to output your 1 ms pulse, and then you would generate 1's, as many as you need for your 1 ms. I'll let you do the math. If you don't want to "oversample" this much, then you can slow down your clock rate to maybe 10 times your 1 ms pulse, which you would then output 10x "1's" for your pulse, and then however many 0's before and after your pulse. So basically all you are doing is using data (0's and 1's) to build your pulse. You could also use the Digital Waveform Editor to help you do so. One advantage of using a data line to generate your pulse is that you can vary the pulse width by adding or removing 1's, and when you are running at 100 MHz, you can get 10 ns steps of how much you want to change your pulse width.
Again, there will probably not be a specific example that does your exact example, but by using bits and pieces of the existing examples, you should be able to figure out which functions you will need to do what you want. Finally, if you are just getting started, I recommend not only looking at a bunch of the HSDIO Example programs, but also the NI Digital Waveform Generator/Analyzer Help document (or the online version), as there is a ton of great information in there about your HSDIO device, like how it works, what features it has, and how to program it. I hope this helps. Please let us know if you have any further questions or concerns. Thanks, and have a great day.
Regards,
DJ L.

Does PXI-6547 support WDT file format

Please correct as needed....
The Waveform Data Type (WDT) is the only file format within the HWS that supports the extended logic states of digital signals.

Pxie-1073 trigger

Can the PXIe-1073 drive/monitor the PXI trigger lines?

Hello Robert,
I have not seen any software that can monitor and display the information of the PXI Trigger Bus that is in the backplane of the PXI. A workaround is using an external card that can be used to export this lines to the front panel of the PXI. Some of the cards that can help with this are the 6652 or the 6653 timing and synchronization cards.
On the following link you should be able to see an example on how to export a Trigger to a PFI line:
https://decibel.ni.com/content/docs/DOC-2350
Also, I would like to show you some articles that speaks how to manipulate the trigger lines:
