Spectrum analyzer with sim and DAQ IV File

Hello..
i have a project that i need to design a Spectrum analyzer with simulation mode and DAQ option. ( so you can generate input signal from LabView and DAQ.
all i look for is a modern Spectrum anlyzer VI file for reference and education purposes
i know there are examples out there in LabView but, i need a modern one with a lot of options and features ( like Impulse respond, marker... filters.....)
there is something i found here on the website, it happen long time ago, and some proffessor from Vietnam created such project. its not with DAQ, but its great for me.
here is the link:
http://digital.ni.com/worldwide/singapore.nsf/web/all/42B390E4624228D486257249001A5349
this kind of Spectrum anlyzer looks great
most appreciate for any help

Hi Eldad,
Thanks for posting and welcome to the NI forums!
The
application you have linked uses LabVIEW to control a Tektronix TDS220
over RS232 (a.k.a. serial port). The TDS220 has a 1GHz sample rate
with a 100 MHz bandwidth--the specs on our DAQ devices don't go nearly
this high, our High Speed Digitizers
would be a better option if you need something comparable. Also, the
programming of the two devices (TDS220 vs. DAQ) is going to be quite
different, so I am not sure how helpful the code from the link would be
for your application. I don't have access to the code or permission to
post it here, but you could always try contacting the original author
(his contact info is in the link you provided, not sure if it's up to
date or not). Again, I'm not really sure how helpful the code would be
for you.
You might want to take a look at the following example to see if it does what you need:
NI-DAQmx: Benchtop Spectrum Analyzer
There
are also numerous examples that are installed with the DAQmx Driver to
help you get started with the API. You can access them from LabVIEW by
going to:
Help >> Find Examples... >> Hardware Input and Output >> DAQmx
There
may not be a ready-made example that will do everything that you
require, but the above should give you a good starting point for
implementing the necessary features yourself. If you run into any
specific issues while trying to program, please don't hesitate to post
to the forum and we'll be more than happy to help out.

Spectrum Analyzer with Tracking Generator - do I have what it takes?

Hi Guys and Gals,
I need to profile the response of some filters in an ultrasonic bit of hardware. I've been told that a Spectrum Analyzer with a Tracking Generator will do what I want in a short space of time, but I don't have one. Problem is I don't know what a spectrum analyzer is (beyond the obvious - analyses the frequency spectrum response).
I have a 100MHz Arbitrary Function Generator under LV control and I have a LeCroy 600MHz Oscilloscope under LV control and I know a bit about writing LV.
The question is, can I use the AFG, the Oscilloscope and LabVIEW to make myself a Spectrum Analyzer to do the job?
Any suggestions or pointers gratefully received.
Dr Phil

I believe a Network Analyzer will be of use to you, and fortunately you have the makings of one. A NA will tell you the amplitude and phase response. The easiest thing to do is to split the signal from the AFG (use a T) and send one signal straight to the scope and the other to the input of the DUT (device under test). Connect the DUT output to the second channel of the scope. Simply measure the ratio of the amplitudes and the relative phase of the two channels and you are all set. The scope probably has these functions built in, otherwise acquire the time series and let LabVIEW do the work (you can also take the power spectrum if you really want a spectrum analyzer). If you want to be careful, make sure that the cable lengths in the two paths are equal, but at ultrasonic frequencies I wouldn't worry about it at all.

Is Adobe CS5 compatible with CS3 and Dreamweaver 8 files

All,
We have eight users that are using CS3 (Photoshop, InDesign and Acrobat 8) plus Dreamweaver Studio 8 on Windows XP Pro 32-bit. Two of these users are moving to Windows 7 64-bit. We don't have it in the budget to upgrade all 8 users. Will Adobe CS5 Premium files (particularly InDesign and Dreamweaver) work with CS3 and Dreamweaver 8 files?
Thanks

InDesign absolutely NOT! InDesign can only save back one version.
But...CS3 runs just fine on Win7 64 bit.
I'm not sure about what issues you'll have with Dreamweaver.
Please post followups in the InDesign and Dreamweaver forums.

Spectrum Analyzer GPIB Record and Save to AVI, MPEG, or MP4 file

My objective is to record a waveform using labview and save it as an AVI, MPEG, or MP4 file to be able to replay it back at a later time.
I would like to know if it is possible to capture a waveform for 30 to 60 second and save it as an movie format file.
I have Labview 2013 version, Spectrum Analyzer N9010A and GPIB-USB-HS.

Start by looking for the LabVIEW driver for your instrument. There may be something in there for capturing your waveform.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to read the data in spectrum analyzer (Anritsu MS2661C) and put it in Excel using Labview

Hi all, I'm new to using the labview, and I have some trouble doing my project using the labview software.
I have been trying to use the spectrum analyzer (Anritsu MS2661C) which connect to computer using the GPIB connection.
I have got the instrument driver which can write and control the instrument using Labview 2010.
and my Question is how do read the data or result from the spectrum analyzer and send it to the microsoft excel?
Do I need to use other software or programming to do this step?
If anyone know how is this done, please let me know.
Regards,
Ery

Hi ery,
In order to send data that you have read in from an instrument to Excel, the most convenient way to do this would be to use our Report Generation Toolkit. The Report Generation Toolkit is a very useful tool that allows you to interface to Microsoft Office software from LabVIEW, including Word and Excel. I am not sure if you are familiar with this, but I have attached a link that explains more about the Report Generation Toolkit below.
Another way would be to use the Write To Spreadsheet File VI. While this will store your data to a spreadsheet data file, it will not allow you to programmatically perform any Excel formatting like the Report Generation Toolkit offers. I have also attached a link to some information on the Write To Spreadsheet VI below.
Also, be sure to check out the Example Finder in LabVIEW for a number of examples on how to write data to a spreadsheet file. From LabVIEW, you can go to Help»Find Examples to launch the Example Finder. From there, you can search for "spreadsheet," which should populate examples for use in different applications. I hope this helps, ery. Please let me know if you have any further questions about these!

Spectrum Analyzer with NI-6111

I am trying to build a two channel (simultaneous) spectrum analyzer using Labview 7.0 and the PCI-6111 DAQ. I can make one channel work but it is very slow, but cannot find a method to acquire the second channel while the first is running. Are there any samples that might be useful? Attached is what I have so far. Is there anything I can do to speed it up? Any suggestions are GREATLY appreciated.

Acquiring_a_Signal_with_FFT_&_DAQ_&_THD_&_OCTAVE_&_TAB_&_CASE.vi ‏452 KB

I've attached an example that I've thrown together that acquires from two channels and performs an FFT of one or both channels (selectable). I didn't have a problem performing frequency analysis on multiple channels simultaneously. One thing to keep in mind though -- the more analysis you do while performing buffered acquisition, the more likely your CPU will run into trouble with transferring data. I hope my example helps.

Acquire encoder position with Motion and DAQ

Hi,
I am trying to acquire an encoder position with Motion. It seems impossible to set the frequency of the acquisition with Motion and I must poll for the position in a do-while loop.
I have read in a lot of threads that one can use RTSI lines to retrieve encoder position with a DAQ Board though it is acquired with a Motion board. But there are no examples at all about this.
To sum up, I need to send Encoder Phase A to RTSI0, Encoder PhaseB to RTSI1 (which I already do), retrieve info with a DAQ device and then calculate rpm.
Christophe
PS: please don't answer with measure angular position.vi or explain me in what this Vi can help me

Hi Christophe,
I'm not sure I understood well what you need. You have the angular position and you need to know the timing, am I right? Can you use an other counter on your card to get the period (or the frequency) of your signal? From that, I think you should be able to calculate the velocity.
I hope this helps,

Incosistencies between Analyzer Server Console and stout.log file

Hi, In stout.log file of application server file there is a record: "Setting Current User Count To: 2 Users. Maximum Concurrent Licensed User Count Is: 10 Users." So 2 licences are ured, but checking "Analyer Server Console" there is only one user connected. After restarting computer "Analyzer Server Console" and stout.log number of users are sinhronized. But I don't know what happens, but after some time this two parameters are not sinhronized anymore. My problem: I have to show the number of user licences used and I am reading info rom stout.log. But something is not correct - it looks like stout.log doesn't show correct values? Do I need to specify some setting or is there a bug in code? My system: Hyperion Analytic Server version 7.1.0 Hyperion Analyzer Server version 7.0.1.8.01830 IBM DB2 Workgroup Edition version 8 fixpack 9 Tomcat version 4 Windows 2003 Server

Hi grofaty. We use 7.0.0.0.01472 and I had experienced the same behaviour, Analyzer Server Console shows one more session than stdout.log. If this difference 1 is a static value than you can assume it as an systematic bug...and do your license counting on it... But again the Analyzer Server Console is not good as it should be for productive usage because all the information is only logged online til the next application restart. E.g. it is not helpful in using it for user tracking purposes. Do you use the stdout.log in such a way or have an idea how to grep measures for session logging analysis: - Session ID - User ID - Client ID - Total Number of Requests - Average Response (sec) - Login Time - Number of concurrent sessions ?

The most resent Firefox update has a conflicting application with adobe and all pdf files have to open firefox before opening

My issue started with downloading the most current Firefox. Firefox opens multiple empty tabs (20 -30 or more) every time I use adobe reader. I changed the action for a content type to show adobe reader. It was showing open the file in adobe in Firefox. I uninstalled and reinstalled Firefox twice and this did not work. I uninstalled Adobe Reader and Air but could not uninstall Adobe Flash Player because of a conflicting Application with Firefox. I then uninstalled Firefox and was able to uninstall Adobe Flash Player. I reinstalled Adobe Reader only and then Firefox. I no longer have multiple empty tabs opening up but each time I open a pdf file, Firefox has to open as well. I am operating on Windows 7 Home edition. Can some one help this is a nuisance.
Thank you,
Steve Zalkin

Try to rename (or delete) the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.
*http://kb.mozillazine.org/mimeTypes.rdf
*http://kb.mozillazine.org/File_types_and_download_actions#Resetting_download_actions
You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).

ITunes folder bombarded with iT and Temporary iTunes files = Blank Library

I opened my iTunes folder and there's a long list of iT files and temp files that using up a lot of memory... according to past topics, it's completely okay to erase them
BUT
the really problem is whenever I open up iTunes, the cursor indicates its taking a long time and after about 20 seconds it opens up with a blank library. Apps, music, videos, everything's gone. I make a playlist and a new temp file is formed in my itunes folder. 's been happening since novemeber -_-

Is that a Sony Vaio you have there?
If so it may have software that is not compatible with iTunes, see this thread:

Filemanagerimpl.cpp-94 with Drag and Drop .mov files

I am working with DSLR footage (1920 x 1080 24p .mov) and for some reson CS5 Premiere Pro will crash randomly (usually about every 2nd-3rd file I import) with a debug event and the dreaded filemanagerimpl.cpp-94 error.
I can only find posts about this happening with capture, but very little about importing and of course NO answers.
I uninstalled and re-installed quicktime and no go. It's something with the filemanager but no clue how to fix that or what it means.

As a follow up, it seems that when I use the media browser pane in Premiere it works fine. It might very well be an issue between windows 7 and Premiere and the way explorer works.

I've started having problems with downloading and opening PDF files. Any hints?

This started late yesterday and I've been unable to download or open or view any PDF files. I've restarted my computer a few times, made sure Preview was open then when those things didn't work downloaded Adobe PDF reader and that didn't work either. Any other ideas????

Back up all data.
Quit Safari. In the Finder, select Go ▹ Go to Folder from the menu bar, or press the key combination shift-command-G. Copy the line of text below into the box that opens, and press return:
/Library/Internet Plug-ins
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then launch Safari and test.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Having trouble with pse7 and opening jpg files

I have been using pse7 for quite some time and today I have started having trouble. It is as if the program is "not responding" for a time. So here is what is going on . . . I can open a file or group of files (jpg images) and then when I ctrl+o to open something new I can't see what is in the folders . . . and eventually it won't even let me open anything. I will ctrl+o and the little blue circle will move, but then go back to the arrow without going to my folders. I'm not sure if this is making any sense, but it is REALLY frustrating me!!! I have restarted my computer several times today and it is not helping. Last week I did update the driver for my printer and now I'm not able to print anything from PSE . . . I don't know if this is part of the problem. I was getting the "not enough memory (RAM)" message last week as well. I don't know if all of this is together, but it is driving me crazy!!! I am in the process of downloading the pse9 trial and I'm hoping that this will help.
I am working with windows7.
thank you!!!

You might have opened several images of large sizes.
You can go to Edit menu > Preferences > Performance
Move the slider to the right to increase the memory allocated to PSE
Also, increase the Cache level.
Restart PSE Editor
The problem also can be, that you have several programs running on your system. You might want to close unwanted programs while working on several images in PSE. This also reduces the available memory for PSE to work on.
Hope this solves your problem

Are there any compatibility issues with Mavericks and EMC Celerra File shares, particularly with the SMB protocols?

Our company uses a EMC Celerra file share, but most of our users are Windows based. We have a small production department of 7 macs. Starting with Snow Leopard, we noticed some issues with SMB. We were able to resolve those issues, but had to wait to upgrade to Lion because there were additional SMB or permissions concerns with the Celerra file share and Lion. Now, we are again waiting to upgrade to Mavricks because of the way it handles user permissions. Does anyone using Mavericks now also connect to a EMC Celerra file share? Thanks!
