Zoom Frequency in Frequency Analysis

Is there a way to zoom in on a range of Frequencies in the Frequency Analysis? I'm looking for noise below 200 Hz but would like to know more specifically which frequencies are involved.
Thanks,
David

You need the Zoom Panel.
Click on the third icon from the left in the second row - this has a + with up/down arrows. The more times you click, the greater the zoom in on the frequency spectrum.
You can drag up or down in the right hand end of the display - where the frquency is displayed - to pull the frequency range that you are interested in into the frame.

Zooming in Spectral Frequency Display

Zooming the height of the spectral frequency display either doesn't work, or doesn't work like it used to. I often want to zoom in on just a narrow frquency band. I used to be able to do this either by using my marquee selection tool on the narrow band and then clicking "zoom to selection" or by clicking repeatedly on the "zoom in" button and scrolling up or down to the desired frequency. Neither of the methods seem to work in CS 5.5. Is there another way of doing this?

Related issue: vertical zoom states of waveform and spectrogram in Edit view are not saved when switching to a different file. You have to manually define the zoom state for each file, which makes it very difficult and time consuming to e.g. directly compare two files at user-defined vertical zoom levels (by switching back and forth).
Windows XP SP3, x86. Is this a bug or a feature? It used to work in AA 3 (and 2 IIRC). The horizontal zoom state is kept when switching between files (assuming the corresponding option in the Preferences is checked).

How to read frequency channel & voltage channels at the same time with different rates?

I am using a DAQCARD 6036E with a SCXI-1000 chassis. I have a SCXI-1100 & a SCXI-1126 modules, along with a SCXI-1124 AO module for voltage output. I am acquiring several voltage input channels with the SCXI-1100 & one frequency channel (frequency signal upto 12000Hz) with the SCXI-1126. I want to configure all the channels in the Measurement & Automation so that I can use the Scale function to setup all the channels. I am using a higher acquisition rate for the frequency channel than the voltage channels. I had the block diagram as attached. When I run the vi, I had the resource problem. The err. msg. is: the specified resource is reserved.. Any suggestions as how to acquire a frequency signal & several voltage signals with this system setup using the DAQ-mx?

Since a common ADC is shared with all your SCXI analog input channels , you will have to sample all channels in a scan list at same sampling rate.
However, you can set up frequency and voltage virtual channels using different instances of "create DAQmx Virtual channel" function in the same task as shown in attached pic, set scan rate and read them using a single DAQmx read

Frequency of words in Arrays

Dear Java Folks,
I still need your help!
I am still having problem after succeeding in tokenizing the Strings in LinkedList.
What I wanted to do is to find the Frequency of words or characters in an Array.
E.g
1�A,C,F,G,A
2�Baby,H,K,A,C,K
3�Oslo,S,F,T,K
The first line will return 2A, 1C, 1F, 1G. Thereafter, I will find the Frequency of the second line which will be 1Baby, 1H, 2K, 1A, 1C etc.
For now, I am only interested in getting the Frequency
of the first line.
My Code
public String DataCall() {
 DataInputStream dis = null;
 String line = null;
 String []words;
 String []Lines;
 List <String>result = new LinkedList<String>();
 List<String> dataList1 = new LinkedList<String>();
 List<String> dataList2 = new LinkedList<String>();
 List<String> onlyWords = new LinkedList<String>();
 List<Integer> frequency = new LinkedList<Integer>();
 int counter = 0;
 try {
 File data = new File("C:/text.txt");
 FileInputStream in = new FileInputStream(data);
 dis = new DataInputStream (in);
 BufferedReader br = new BufferedReader(new InputStreamReader(dis));
 line = br.readLine();
 if (line != null) {
 Lines = (line.split(" ")); //Split the first row or line
 for(String datas : Lines) // add the data to the Linkedlist
 dataList1.add(datas);
 for (int i = 0; i < dataList1.size(); i++) {
 words = (dataList1.get(i).split("�")); // split to get to �
 for (int b = 0; b < words.length; b++) {
 String []wordCount = words.split(","); // split the remaing words or characaters
 for (String saveD : wordCount)
 onlyWords.add(saveD); // add the data to Linkedlist "onlyWords
 // Start the frequency calculation
 for (int point = 0; point < onlyWords.size(); point++)
 if (!dataList2.contains(onlyWords.get(point))) //Initially dataList2 is empty here
 dataList2.add(onlyWords.get(point)); // add data to Linkedlist "datalist2"
 frequency.add(1); // add 1 to (int) Linkedlist "frequency"
 else
 int tmp = 0;
 tmp = onlyWords.indexOf(point); //get the index where the "word" occured first
 counter = frequency.get(tmp); //ge the value of the same index in the Linkedlist "frequency"
 counter++;
 frequency.set(tmp, counter);
 for (int k = 1; k < dataList2.size(); k++) {
 System.out.println(onlyWords.get(k) + " " + frequency.get(k));
 else System.out.println("There is no data to read\n");
 catch (IOException e) {
 //catch io errors
 System.out.println("IOException error: " + e.getMessage());
 finally {
 // if the file successfully opened
 if (dis != null) {
 try {
 dis.close();
 catch (IOException ioe){
 System.out.println("IOException error when trying to close the file: " + ioe.getMessage());
 }//end if
 }// end finally

Creating custom tiles for IE11 websites: poll frequency should be increased

not sure why the frequency is set to minimum 30minutes currently, but if it can be set to at-least 5 minutes (ideally 1 minute) that would be great.
i have several cases, where i can probably monitor N number of things just by adding tiles for 'short status' messages, rather than logging to their servers. 30minutes is too long a time to know latest status.

Hi Javsha,
See the following link to know how to set poll frequency using frequency property.

Creating of the word-frequency histogram from the Oracle Text

I need make from the Oracle Text index of the "word-frequency histogram", this is list of the tokens in this index, where each token contains the list of documents that contain that token and frequency this token in the every document. Don´t anybody know how to get this data from Oracle Text index so that result will save to the table or to the text file?

You can use ctx_report.token_info to decipher the token_info column, but I don't think the report format that it produces is what you want. You can use a query template and specify algorithm=count to obtain the number of times a token appears in the indexed column. You can do that for every token by using the dr$...$i table, as shown below. Formatting is preserved by prefacing the code with pre enclosed in square brackets on the line above all of the code and /pre in square brackets on the line below all of the code.

Campaign Optimization using RFM Analysis

I'm interested in the tools offered by BI for the RFM Marketing Analysis (Recency, Frequency, Monetary Value Analysis). I've read this information:
http://help.sap.com/saphelp_nw2004s/helpdata/en/c5/bd493b13bab710e10000000a11402f/frameset.htm
http://help.sap.com/saphelp_crm40/helpdata/en/d3/11b71b8182ed4995eaad3dc644c771/frameset.htm
I understand that the all process needs a CRM deployment as well as BI. However I'm wondering if this kind of scenario can be implemented without a full CRM installation. In particular I'd need to use an Internet Sales - BI landscape.
When calculating the Response Rate, I have to determine the Addressed Business Partners. One way to provide this data is using the ODS object Campaign/Target Group/Business partner Assignements
(<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/36/df333bf1047532e10000000a114084/content.htm">0CRM_TGCT</a>). This object is filled by data from the CRM application. Is it possible to take data from Internet Sales instead?
Otherwise, can you briefly explain the Intelligent Web Analytics feature of Internet Sales? I know it requires BI. How are the two application integrated?
At http://www.sap.com/solutions/business-suite/crm/internetsales/featuresfunctions/index.epx I read:
Take advantage of a broad range of Web analytics that enable you to track online sales, capture customer behavior, analyze Web site metrics, and improve online sales performance.
What kind of customer behavior characterization is offered by these Web analytics?
Cheers, Davide

The PP/DS Optimiser has quite a few restrictions associated with it, and can cause unpredictable results if any of these restrictions are met. See SAP Note 712066 for full details as I am not sure of the exact conditions you are trying to optimise. The key one may be:
The campaign optimization is based on the bottleneck resources. There must be no direct or indirect time link (in the form of constraints or material dependencies) between the operations or orders that are planned on the bottleneck resources. In particular, bottleneck resources may be used only once in the production flow.
Hope this helps

The Signal analysis functions of the DIAdem-CAL can not use.

I use a DT3003 board for Data Acquisition in my system. My data is signal of Electromyography,and it needs the DIAdem-CALC "Signal Analysis" such as FFT.But these functions in my DIAdem are disable, Why?

Yes!
We do need Frequency Analysis.The EMG is some kind of time-voltage signal.DIAdem do us great help in data sampling.We need to get information such as Average Amplitude, spectral parameters like Mean Power Frequency,Median Frequency from the raw EMG. Is "Signal Analysis" function of the DIAdem standar version able to full fill our demands?

What is the best tools for spectrum analysis

There are many spectrum analysis software component in the of NI product(SMT, advanced signal processing, basic ones).
May I know which is the lastest and best for use.
I am trying to collect data from DAQ 5102 then do FFT. Also, may need select centre frequency and frequency band etc.
A band pass or low pass filter may also need in the future.

Hey turbot,
Thanks for contacting National Instruments support. Each set of the vis you mention are the latest, and some use similar methods to do the FFT than the other. The SMT is usually the best in most applications. There is also another option in the case of scope, you can fetch FFT data from the driver. The FFT is not actually implemented in hardware, but in the driver, and this is transparent to the user. It's simpler to use, but not as efficient as the SMT.
I hop this answers your questions. Let me know if I can be of further help.

Exporting a report with a chart.

Post Author: Coleen
CA Forum: Other
Hello, I am using Delphi7 with CR XI. When I export a report
with a chart to a pdf in my development environment it works fine. But
when I distribute my application, the export works correctly except the
chart does not display. I am using Installshield to distribute
the following merge modules: CR11_rdc_license, CR11_rdc_reportengine,
and CR11_rdc_runtime. What am I missing? Thanks,Coleen

Hello Russell,
The Joint Time Frequency and Order Analysis Tool comes with example data. If you use the sample data, do you see the same behavior? Here are the steps I took:
Run the VBS script Time Frequency and Order Analysis 111.VBS to launch the tool.
Select New Data File
Select Noise data.tdms and Open. This is in the Sample Data folder in the tool's folder Time Frequency and Order Analysis 111
Set the Time Channel to "1 Time" and set the Signal Channel to "3 Noise_2"
Select Spectrum 3D CharDiag.TDR as the Report Templace.
Select Joint Time Frequency Spectrum as the Analysis Type.
Select Run Analysis. This will load the analysis data into a report
Double-click on the graph to open the 3D Axis Definition window
Select ... next to the Characteristic diagram to open the Curve Parameters window
Under the Interpolation tab, uncheck Interpolation. Click OK and close both dialogs. The graph will re-draw.
Go to File > Clipboard or press the Copy Graphic to Clipboard button.
Paste the image in Paint or Microsoft Word
With these steps, I do not get an error with the clipboard. Are you able to export to clipboard if using the sample data Noise data.tdms? Does copying to clipboard work with any data? I'm trying to determine if maybe a certain large or small set of data could be causing the issue, or if you always have this issue.

Hi Eric and thanks for your response
1. I am looking to do the frequency response
2. I do have the enterprise edition which also include LabView and CVI
3. I'm working on a project which is written in VB6 and that is why I prefer to use the measurement studio to perform the signal analysis. I know that I can do the analysis in LabView and call it from VB. I will check that option only if I won't be able to accomplish the task with the measurement studio. What do you think? (see the list of task I need to deal with)
4. My project requires reading data (could be hundreds thousands of points) and then, displaying:
            Time domain
            frequency domain
            frequency response
            histogram
            Pulse response
    Also calculating:
            SNR
            Linearity
            rms
            p-p
Any advice would be greatly appreciated

I have an optical sensor and two hall effect how can I data log?

I have built a test rig which consists of a gyroscope. The gyro is spun up by and electric motor.
I need to measure the speed of rotation. I’m using an optical sensor and two Hall
Effect sensors. I would like to record the
output of these and I would like to build in some redundancy because there will
be another bigger rig that will require more measurement. E.g. vibration.
I’m new to data logging so I’m not sure which hardware I
should be getting.
Thanks

analog inputs are the most universal. with software such as the functions included in the Sound and Vibration Measurement Suite, you can analyze the analog input channel which is connected to your hall effect and optical sensors for frequency and speed. Vibration specific input cards will power accelerometers. with the speed and angular position sensors (hall effect and optical) you can combine this information with your vibration sensors to determine the movement of the device with respect to position and speed. These order analysis functions are part of the Sound and Vibration Measurement Suite.
What is more is that the Suite includes an assistant. The assistant allows for the capture and datalogging of all analog and digital inputs as well as frequency and vibration analysis. This is all configurable and does not require any LabVIEW programming. If you decide you want LabVIEW programming, all the functions are there to support LabVIEW as well.

Intensity graphs in diadem

Can you make intensity graphs in diadem like in labview. For example I
have data that is in one channel group, that has about 100 channels.
Each channel has a 1d array of data points which have about 50 points
each. Is it possible to plot this 100 by 50 array in diadem as a
intensity graph, and how would it be done?
Thank you

Hi Timothy 123,
You can achieve intensity-chart-like behavior in DIAdem by using a 3D surface graph. Please refer to the following tutorial for one such implementation:

Is SSAS the right tool to replace SAS Enterprise Guide?

I am in the process of studying the feasibility of replacing one of our custom built SAS Data Warehouse with Microsoft BI/DW stack.
I have one specific question that I hope someone here who knows both SSAS and SAS Enterprise Guide can tell me. Feature by feature, in what extent can SSAS replace SAS
Enterprise Guide?
To those who has less knowledge of SAS Enterprise Guide, it is a client app that let power users query against database tables/views and apply various statistical analysis
to the data then output (print/email/save) the result (grid/chart/etc.).
To name a few of these statistical analysis,
Under Describe, there are Distribution Analysis; One-Way Frequencies; and Table Analysis;
Under ANOVA: t Test; One-way ANOVA; Nonparametric One-way ANOVA; linear Models; Mixed Models.
Under Regression: Linear; Nonlinear; Logistic and Generalized Linear.
Under Multivariate: Correlations; Canonical Correlation; Principal Components; Factor Analysis…
And if SSAS along is not enough, what else are needed?
Thanks!

Hi Hommer,
Based on your description, you said that “SAS Enterprise Guide is a client app that let power users query against database tables/views and apply various statistical analysis to the data then output (print/email/save) the result (grid/chart/etc)”. Since
we are not expert about SAS Enterprise Guide, we cannot give you an exact conclusion. However what we can give you is that there are many adventures of SQL Server Analysis.
High Performance.
During cube processing SSAS will pre-calculate and physically stores aggregations of facts. Therefore, when the query is fired SSAS does not have to calculate the outcome from the underlying details but can take the values directly from the stored aggregations.
High Security
You can use the security setting to give end-users access to only those parts (slices) of the cube relevant to them.
Multiple Access/Frontend-tools
End users can use Microsoft Excel as a power full front-end tool on top of the cube. Besides that the same cube can at the same time be used as a data source for SSRS and SharePoint (KPI-) Web Parts.
For analytical applications, performance management, or just about anything with a KPI, Analysis Services is the perfect companion for SQL Server. These are complementary databases that do different things well. Using the right tool for the right job will
make development faster and usability easier.

Count analog pulses

Hi All,
I want to create an application that uses a variable signal (random rectified sinus pulses with various amplitudes: 1V, 2V, 3V, 4V) and counts all the pulses during a specified interval of time (1 second). I need four I32 counters that show how many pulses with an amplitude of 1V, 2V, 3V and 4V have been recorded during the interval of 1 second. Any ideas would be greatly appreciated. I already created sort of a virtual test signal that is able to generate pulses of various amplitudes. Later I will use signal captured from my ADC board (PCI 6251). I had a look through the examples provided by NI, but I've been unable to find what I need.

Hi Jim,
I would be glad to help you with this question. It sounds like you are trying to convert a square wave (coming from your wheel) into a graph of speed (RPMs) vs time. You should be able to use the VBScript example located at (http://zone.ni.com/devzone/cda/tut/p/id/3549) to perform this task. Please follow the link at the bottom of the page to "Joint Time Frequency and Order Analysis Tool - Download."
Specifically, you will need to perform the following steps:
Download the Joint Time Frequency and Order Analysis Tool using the link above
Save two sets of data in your preferred file format (for import into DIAdem). You should have one data set for your square wave (obtained from your wheel), and another data set for the time data associated with your square wave samples.
Drag the square wave and time data (two data sets) into the DIAdem data portal. Note the channel names that are associated with each data set.
Select the "Script" window on the left, and click on File >> Open. Navigate to the directory where you saved the Joint Time Frequency and Order Analysis Tool files, and select the "Time Frequency Order Analysis" script.
Click Run Script to execute this script. From the dialog page, navigate to the "Analysis Type" menu, and select "RPMs Channel from Tach Channel".
Select your "Time Channel" and "Tach Channel" according to the channel names that you imported earlier. You can also choose the number of pulses per revolution for your wheel.
Click on "Run Analysis" to obtain the velocity-time data that you are looking for.
I hope this information helps. Please let me know if you have any further questions and I would be glad to assist you in any way possible.
