Need a good Wifi Spectrum Analyzer
I am looking for an APP that is a good Spectrum analyzer.
I have a iPhone5, (will be updating to 6 + soon)
I do a lot of work troubleshooting wifi networks, and on my Android, and I though my older iphone 3gs) I had a good Spectrum analyzer for 802.11 wifi.
I cannot find a good now, and I hate to have to go to an android just for this reason alone. need mainly 2.4 GHz, but 5GHz ability would be nice to have.
I need to able to see each AP, the SSID and channel it is broadcasting on, and I refuse to spend $300 for the Wi-pry external device by Oscium.
I am already using the Net Analyzer and Status bundle, which is great for networks you are already connected to, but I need to see other networks, and their SSID and their signal strengths individual by AP.
Any help would be appreciated. If there is nothing I may be forced to downgrade to an Android device, and that would suck as I hate Android.
Thanks
Hi Kappy
thank you so much for the info I have a Netgear modem and anned on getting a AirPort Extreme this should still work right ???

I Need some info about interfacing the PC or laptop to Spectrum analyzer using Labview
we need to control the spectrum analyzer using an interface that will be developed using Labview .
Spectrum analyzer will be connected to tha PC using RS 232C and the waveform observed will be seen in the PC interface of spectrum analyzer.
Pls send some info regarding dis.Using a spectrum analyzer with LabVIEW is a pretty common application, my first program 15 years ago did this. What we need to know to help you though is what model spectrum analyzer are you planning on using? Most of the ones I'm familiar with use the GPIB interface rather than RS232, but that isn't a major issue, the spectrum analyzers command set is the important one. There are a lot of LabVIEW drivers available for a larger number of analyzers, here on the National Instruments' site. Although most use the GPIB interface (or ethernet), they can be used as a starting point to develop an RS232 driver if one isn't available, assuming that there is a driver for the model that you have, or a closely related one (manufacturers frequently use similar command sets within a model type).
So, what type analyzer are you using, and what types of things are you planning on doing with it?

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 helpHi 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 to create a Spectrum Analyzer?
Hello people,
Well i need to create a Spectrum Analyzer in my application, to analyze the frequencies from a auido capture.
Any tips? Because i don't know where to start to develop this.
My best,

Ok i see. But how to create the graphics, exist some kind of free library related with this?You have a lot of learning to do and the FFT is the least of your worries. Check out Java implementations of the FFT from the source forge repository. Take a look at my second post in Perform Hamming window and FFT with Java for an outline of what you have to do to create the spectrum values. Take a look at JFreeChart for the display of the results though you might find it a bit slow when running real time (I use my own very very simple but fast charting).
You can do everything mechanically without any real understanding what you are doing but I hope your examiners are looking for more; I would be. -
I am trying to construct a GUI to control and display an Agilent E4408B spectrum analyzer.
I have created a serial connection to the spectrum analyzer and have managed to control it and query for frequency and power using SCPI commands
sent across the serial link, so I know the serial connection works.
However I am getting nowhere in trying to make a GUI using Labview. I have downloaded the drivers and there seem to be bits of the functionality I need
but I do not know how to "hook up" the serial connection to these bits.
Does anyone have an example of a similar applcation in Labview? It does not need to be an agilent specan, any instrument that has driver supprot and uses serial communication would be a good example.
Many thanks!Hi NIer,
I am new to Labview and trying to build a GUI controlling Agilent E4408B using GPIB-USB-HS. I have downloaded the driver (plug and play) from NI website however the downloaded document makes me confused where to start. Would you mind sending me a proper tutorial document please? Any suggestion will be highly appreciated!
I need this to be done urgently and hope you can help!
Thanks a lot!

I updated my iphone and when it came time for activation it won't work and keeps telling me to try again. At the top it says "No Service" and I have my SIM card in and a good WiFi connection and have connected it through iTunes but it says I have no SIM card and need to disconnect and insert my SIM. I don't understand why this keeps happening and it's been going on for a wile now. I have tried over and over again to get this iPhone to work but nothig is happening. I've even gone on the website for support (apple.com/support) but cannot find anything that will help me with this situation. Can someone please help me find a solution to this problem? I have been without a phone and do not have money to buy another one and it is crucial for me to get it fixed. Thanks.

What computer operating system is involved in the Premiere Elements 11 and 13 issues? Same computer or different ones? Are you installing from purchased download installation files or from purchased installation disc? Does Premiere Elements 11 work completely on this computer whereas 13 will not?
Let us go through the typical drill so as to take nothing for granted.
1. Does the problem exist with or without the antivirus and firewall(s) disabled? Are you working with an individual home computer or in a
school or company network?
2. Are you running the program as Administrator and is there any "domain" account involved?
3. Is your video card/graphics card up to date according to the web site of the manufacturer of the card?
4. Do you have the latest version of QuickTime installed on the computer with Premiere Elements?
Let us start by ruling in or out any of the above, and then we can decide what next.
Any questions or need clarification, please do not hesitate to ask.
Thank you.

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,
EryHi 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!

How can I get a Visa Reference Number on a Spectrum Analyzer?
I have a GPIB Address of 18 on a 8593 EM Spectrum Analyzer. How can I get a VISA reference Number for my VI program
You must have a pretty old version of LabVIEW if you need a session ID instead of just a VISA Resource. If that's the case, you need to first use an VISA Open function in which you specify a resource name of GPIB::18. The open function will return a unique ID that you wire to either VISA Write/Read or a subVI in a driver.

Labview driver for HP 8560 EC Spectrum Analyzer
I'd appreciate it very much if somebody help to find
Labview driver for HP 8560 EC Spectrum Analyzer using GPIB.Unfortunately I was unable to find a driver for this instrument either. This leaves you with one of a couple options. First, I would like you to submit a request for this driver at:

Sound Input Read Spectrum Analyzer
I am working on a project with Arduino to do a spectrum analyzer. The LVIFA part of it is working fine.
The part that I am struggling with is the audio input.
I am using the Sound Input Pallet.
My troubles are two-fold.
1. A single read takes quite some time and I need to have a pretty quick response. I decreased the samples per read and came up with problem #2.
2. I can get one read out of the Sound Read In and then the VI locks up. I have my timeout set to 1 Sec and it never times out. I have to restart LabVIEW.
While it would be nice to have this VI working, I'm not even sure that I am using the correct tool. If I am going to be running an audio spectrum analyzer display off of the data input, I need to response to be within a few mS (ie. <200) so that it looks visually correct.
If this library will not achieve this, then I need to look into a different tool.Hi,
I have a similar project, actually I am using a Audio frequency range as input to the Arduino and do an FFT to receive the spectrum out of it.
See the YOUTUBE video I did and the code in *.jpg. I took actually the Continous Input example and modified it.
Hope that helps.
Keep me posted, since we might work on a same project.

Spectrum Analyzer.VI 392 KBYour 'by the way' is probably the reason you are having problems. Enable tulip support in MAX for VISA and see if it works then.

I can't find the "spectrum analyzer" in iTunes 11
I can't find the "spectrum analyzer". Was it removed in 11? I need it to adjust levels/EQ
You might probably like this plugin: http://apptree.net/ledsa.htm
To install it, simply drag it to /library/iTunes/iTunes Plug-ins
To use it, re-open iTunes and choose it as your visualizer effect. You can hit cmd+t to activate/deactivate and with a right-click on the analyzer, you can choose even colour and many advanced options...

ADVANTEST 3131A SPECTRUM ANALYZER AND labVIEW
Hello,
Trying to control R3131A spectrum analyzer connected through GPIB-USB-B and my laptop using Labview8.5.
I want to read frequency(Hz) from R3131A,and i want to send my measurments to an exel file ...
I have install the labview 8.5,the Measurment and Automation for finding my instrument and i have download the Advantest R3131A Drivers-libraries from that page .... http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=82 and then i install it in Instrument I/O>Instrument Drivers palette. I have read the examples code who coming with the drivers but i don't know which example can help me... If someone knows something,or have an example code who doing that or other help,please send a message.. thanks!..The typical way to make a measurement on any instrument is as follows:
1. setup the instrument for the measurement.
2. carry out the measurement.
3. store result in a file
1. In this case, you want to setup the instrument to carry out a frequency measurement. Although I am not familiar with the Advantest SA, I'm sure it should be similar to the Agilent or Rohde & Schwarz SA. So you first need to set the span wide enough to find the Center Frequency that you want to measure. Then place a peak marker and set the center to the peak value. You then narrow the span in order to improve your measurement. Most likely adjust your resolution (BW) and place a peak marker. You have now setup the instrument for the measurement. The example should contain what you need to accomplish this. Otherwise the user manual should give you the instructions on how to create the commands.
2. You can read the values associated with the marker which will give you the frequency and amplitude. There should be seperate instructions for these. So you can read the frequency by itself. There should be an example of this as it is a very basic measurement.
3. Storing the results... to Excel.. -sigh- Most people refer to Excel, but end up needing to use a different function. In any case, are you writing to an existing Excel Spreadsheet which already has information in it? If not, you can use the "Write to Spreadsheet File.vi".

Where can I download a LabVIEW GPIB driver for an ANDO AQ6315E Optical Spectrum Analyzer?
Where can I download a LabVIEW GPIB driver for an ANDO AQ6315E Optical Spectrum Analyzer?
Thanks.
Solved!
Go to Solution.The Instrument Driver Network has all the drivers for instruments. There is no driver specific to that model, but there is one for the 6310B. Perhaps that may work for you. You may need to modify it. If not, you will need to write one yourself. You can get a lot of material for this here: http://www.ni.com/devzone/idnet/development.htm

Using NI PCI-5640R as Real-Time Spectrum Analyzer
Hi,
The code for NI PXIe-5641R Real-Time Spectrum Analyzer demo is posted HERE for LV 2009. I want to use the same code for NI PCI-5640R instead of NI PXIe-5641R. Since I am using a 5640R, I have changed the device in the project.
Can any one guide me what else changes I have to make in this Demo code so that I can use the same code for NI PCI-5640R
instead of NI PXIe-5641R?
Thanks and Regards,
Rashid
Solved!
Go to Solution.Hi Eug,
It sounds to me like you need to go back and re-install support for LabVIEW 2009 and 2010 through the NI-RFSA driver. You can do this through Add/Remove Programs. Select National Instruments "Change/Remove" and when the pop up window comes up select NI-RFSA and select "Modify." This will re-load the installer for NI-RFSA and through there you can add/remove support for versions of LabVIEW. Make sure that LV 2009 and 2010(if you're using it) are selected.
As for your application, if I understand you correctly your setup goes something like PXI-5600»PXIe-5641R»PXI-5610 (»PXI-5690?). If you're just trying to acquire a signal on the 5641R and amplify it digitally before replaying it on the AO port, then you could try to use the example code "ni5640R Analog Input and Output" that is found here:
C:\Program Files\National Instruments\LabVIEW 2009\examples\instr\ni5640R\FPGA\PXIe-5641R\ni5640R Analog Input and Output\
as a base to follow, but you'll need to modify the code so that you're not providing the AO data from the host, instead you'll re-route the AI data on the FPGA through some amplification block and then feed that to the AO port. If you're including the 5600 and 5610 in this process, then that modified example will just need to include some code on the host to setup the 5600 for downconverter only mode and the 5610 for upconverter only mode. There are examples of this that you can find in their respective driver examples:
C:\Program Files\National Instruments\LabVIEW 2009\examples\instr\niRFSA\RFSA Downconverter with External Digitizer.vi
C:\Program Files\National Instruments\LabVIEW 2009\examples\instr\niRFSG\RFSG External AWG (5610).vi
The addition of these last two pieces of code will make this modified example look a lot like the code that NAyer linked above without the FFT processing.
I hope this helps.
