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 can you create a voice recording and save it as an mp3?

I want to create a voice recording and save it as an mp3. How can I do that on the MAC? Right now I can only think of recording the voice in iMovie, but it does not have a choice to save as an mp3.

Rather that iMovie, you may want to check our Audacity.
It's a free, open-source audio editor and recorder.
You can easily save a recording as an MP3.

Hi,
According to my analysis, for Digital Signatures: Adobe has changed the behavior around digital signatures and SharePoint-hosted PDF files. Now, when digitally signing a SharePoint-hosted PDF file, it will be saved directly to SharePoint if that PDF file
is already checked out. If not, the user will be prompted to check it out. When digitally signing a SharePoint-hosted PDF file in Acrobat X, Version 10.0, the user would be prompted to save that file locally and would then need to upload it separately to SharePoint
as a new version.
I suggest that you use Acrobat X, then check the result. For more information about Acrobat X, please refer to
http://blogs.adobe.com/pdfitmatters/2011/06/whats-new-in-acrobat-x-version-10-1.html
In addition, you can also consider the following third-party tool:

Take screenshot and saves the image to a PNG file

Hello,
How can I take screenshot and save the image to a PNG file?
thanks,
Avivit.
Solved!
Go to Solution.

this is a quite reproducible problem. Some more clarification on my part might help:
I have a loop that contains, among other this, (1) a sub-VI that prints-screen and saves as a png and (2) a sub-VI that emails me the png file as an attachment. The 1st sub-VI simply uses the user32.dll to simulate a print-screen key stroke, calls clipbpard get image, and then formats and saves the image to a png file using the built-in VI write-to-png. This loop should update this same png file, because the path does not change. However, I've noticed that while the loop is running the png file does not update. It simply keeps sending the 1st image it took. The image updates if the VI stops and is run again. I assumed the problem was either with the clipboard not updating or the file not writing.
I think the png file remains open while the main VI (i.e. this loop) runs because I cannot delete the file while the VI is running, only once it stops or is quit. Windows gives me an error that the file is currently in use by labview. Therefore, I think the file is not updated because it remains open.
I've attached the print screen VI. Feel free to stick it in a loop and give it a try if you don't spot something obviously wrong. I did not include the main-VI that I actually use since it contains a lot of instrument I/O, which would prevent someone testing the VI.

Tracks sold by the iTunes Store have been AAC since the Store first opened. They've never sold tracks in MP3 format. You can convert the tracks, though, if you need them as MP3. See:

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 gpib programming

Hi
I am new in Labview, I am trying to program my spectrum analyzer(MS9710B) through GPIB in a way that I can get the graph same as thing I see on CRT screen of
Spectrum anlyzer. Could you help me what is the first step to start my program?

There is an driver from Anritsu. Go to the main Instrument Driver Network for general information on what a driver is and how to use one. Be sure to start learning LabVIEW first with the basic tutorial.

Webcam continuous capture and save to avi later

Hello,
I am new to LabVIEW. If anyone could help with the USB webcam and LabVIEW 2010. I have all the IMAQ drivers installed.
What I am try to do is capture video continuously into a buffer memory or an array and be able to extract that buffer video and save it as an AVI video.
So the main question is buffering video in memory and write as an avi file in later time.
Sorry if this confusing. Please let me know, I can be more details to clear thing up.
Thank you so much for all your help.

Hello Rory,
Queue is an array with first in first out mechanism which allow you to keep the images in the memory. To create queue, you would need to use Obtain Queue function with string name and image data type as input, the result is that you have a queue to put your image into. During each acquisition loop, you would need to create a new IMAQ image before enqueueing so that each images has it's own memory space.
Attached is an example that you can try to see as an example, in addition, LabVIEW example finder also have many queue examples.
Hope that this help you started.

Hello Jeff,
From the LabVIEW Help description:
Sound File Write Simple (Windows, Linux)
Writes data from an array of waveforms to a .wav file. This VI automatically opens, writes to, and closes the .wav file. Windows You must have DirectX 8.0 or later to use this VI. Linux You must have the Open Sound System (OSS) driver to use this VI.
So, the data input to Sound File Write Simple.vi is an array of waveforms. However, if you only have one waveform, you can build an array that contains only your single waveform using the Build Array VI. As described in the LabVIEW Help description:
Build Array
Concatenates multiple arrays or appends elements to an n-dimensional array. You also can use the Replace Array Subset function to modify an existing array.
So, for example, you could run your single waveform into the Build Array function and get an array of waveforms containing only your waveform. You could then wire this array of waveforms to the Sound File Write Simple.vi. This is shown in the image below.

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.

How can I take a file that has individual letters in it and save each one as a seperate file?

I have a file that has 55 letters to individuals in it and I want to save each page as a seperate file by the name of the person. Can I do this?

The built-in Extract command will do it, but if you want each letter named using a specific name you would need a script.

Save or export an opened .mp4 file without re-encoding

How can I save or export an .mp4 file that I opened and trimmed without being required to re-encode it. I'm looking for an option to either save the .mp4 file without exporting, or export with a passthrough option such as the one available when using QuickTime Pro. Thanks.

Hmm, I would have expected inclusion of the basic feature set of QuickTime Pro to be a prerequisite for any commercial audio editing program.
The reason commercial audio editing programs don't work the way Quicktime Pro does is Quicktime Pro really isn't an audio app. If Quicktime is able to cut an trip an mp4 file (m4a, aac, whatever you call it) it's becaue it's editing the stream directly, probably similar to the way a file-splitter would work. MP3 was able to have this one too, one could chop an mp3 up in to parts without re-encoding...however, due to the way data is represente in a lossy format, you have several limitations in doing so.
Commercial Audio applications don't do this because it's not going to be done by professionals...even if Audition had this feature, it wouldn't be able to work the same as cutting a wave file. You have servere limitations on where you can cut a lossy audio file up without having to re-encode it.
Cutting the bitstream of an mp3 or m4a file is generally not a standard inclusion for any audio program...
But, remember, Quicktime is a "basic" video editor...not an audio editor nor should it be confused for one.

HT3775 I have a mac book pro and I can not open an MP4 file, this is disheartening

I can not play an MP4 file on my laptop and I have a mac book pro 13inch which I bought in 2012

That's weird. Do you have Quicktime or iTunes installed? Or any media program?
