Viewing spectrum analyzer on LabView

I am using LabView 7.0 with agilent(HP) E4403B spectrum analyzer.
I have no problem controling and getting measurements.
How can I get on LabView the screen of the spectrum analyzer? I mean to see the screen just like if I was looking at the device itself?

Hi Tzviel,
I don't have any experience with this device in LabVIEW, but are you using the instrument driver? You can find that here. There are several example VI's with this driver and there might be one here for what you are wanting to do. Please repost if you have questions with the driver. Thanks!

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?

Can I view spectrum analyzer (HP 8562A) output on LV signalExpress

Hello guys ..
Just wondering if I can get my graphs from spectrum analyzer on LV SignalExpress? Is there a special driver I should download?
Thank you

Hi,
You can view your data from the HP 8562A in LabVIEW SignalExpress by creating a user-defined step. This applies to any instrument not supported by the native SignalExpress steps. To do this, you need to follow the Creating SignalExpress Plug-ins with LabVIEW DevZone.
On a side note, National Instruments has developed some plug-ins, such that a few 3rd party instruments can be controlled through SignalExpress. The plug-ins can be found on this KnowledgeBase. Unfortunately, the HP 8562A is not one of the instruments on this list, nor could I locate a supported driver for the HP 8562A on ni.com/idnet. To communicate with your device, you could use low-level VISA commands or utilize the Instrument Driver Development Wizard.
Let me know if you have any more questions.

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".

DEVELOPING SPECTRUM ANALYZER

Can one claim of DEVELOPING SPECTRUM ANALYZER using Labview? B'cos developing mean writing our own source code and not using the available vi's such as FFT.

Are you developing the hardware, too? Or just the software?

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.

How to measure static phase noise by N4440A spectrum analyzer

Hi, i am new in the RF measurement, and i have to measure the static phase noise, stray and pulse modulation of a DUT, please explain me how to use the spectrum analyzer (N4440A) for this purpose. It will be very helpful for me if you explain the steps for the measurement. Thanks and best Regards

Hi Ikram!
This is Peter Erskine in Applications Engineering. I was not able to find any information on a N4440A Spectrum Analyzer. However, I was able to find information on a E4440A spectrum analyzer. This is a spectrum analyzer developed by Agilent, and you can find the user manual here.
If you are looking to use this spectrum analyzer in LabVIEW, National Instruments has the E4440A instrument driver page that will help you out. If you have any additional questions about how to use LabVIEW with this analyzer, please let me know. I will be more than happy to answer any questions you may have.
However, if you are looking to get help on the spectrum analyzer itself (without the use of LabVIEW), I would suggest contacting Agilent's technical support either by phone or on their forums for additional information.
Have a great day!

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!

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:
http://zone.ni.com/idnet/other.htm
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://zone.ni.com/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would sugg

LabView drivers for Agilent 54830B scope or E4402B Spectrum Analyzer?

Where can I find LabView drivers for the Agilent 54830B scope and the E4402B spectrum analyzer, or at least a driver for another instrument in the same families that I could modify? There are none on the NI site or the Agilent site.

One thing that I have done several times is get a LabWindows CVI
driver from Agilent. You will be provided with a .fp file. LabVIEW
has a link under the Tools>>Instrumentation menu that allows you to
"Import CVI Instrument Driver." This will take the function calls
from CVI and build a set of VI's with the same name. The vi's will be
wrappers for a dll that is used by CVI and other text based languages.

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

Communications between LabVIEW and spectrum analyzer

hi, im a beginner in LabVIEW and spectrum analyzer, and im now trying to let LabVIEW captures signal coming from spectrum analyzer. i have all the required components needed but i have totally no idea how to get started, is there any exercises or labs available here?

It will depend on your method of communication with the device. If it is RS232 you can go to the example finder (Help > Find Examples) and search for RS232 or however you plan on communicating with the device. Or you can browse the catagories for examples on various topics.
Depending on the device the manufacturer may have LabVIEW drivers on their web site. But anybody will need more information on the analyzer and the signals before you can be helped.

HP Spectrum Analyzer LabVIEW Driver/Example

I'm trying to use LabVIEW to control an HP E4403B spectrum analyzer. The LabVIEW I installed is 2009, the drive/example I downloaded is from the link below:
http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=309EBE8FF8BC0E76E0440003BA7CCD...
I tried all the example program but none of them worked. Some commands like *IDN workes okay, but if I run the example programs, it will cause the spectrum analyzer "Undefined header" error.
Any one with experience of using HP spectrum analyzer can give me some clue about what's wrong?
Best regards,
Guangde

Hi Dennis,
Thank you for responding to my message.
I deleted some of the commands from two of the subVIs, the error is gone. But the program is still not working right. The following is some details:
The program I used is: Agilent ESA PSA Series Acquire Trace which is an example of Agilent ESA PSA Series.
In the subVI: Configure Sweep Coupling.vi, I deleted WE:TIME:AUTO ON; and :BWID:VID:RAT:AUTO ON; from the following commands:
WE:TIME:AUTO ON;
:BWID:AUTO ON;
:BWID:VID:AUTO ON;
:BWID:VID:RAT:AUTO ON;
In the subVI: Configure Acquisition.vi, I deleted ET:AUTO ON;
:INIT:CONT OFF;ET:AUTO ON;ISP:WIND:TRAC:YPAC LIN;ISP:WIND:TRAC:YDIV 10.000000;
So I can run the program through without an error message. But it doesn't seem it's measuring. Another problem is that it runs very slow, about 2 to 3 seconds per cycle.
Please let me know what I need to do after I deleted the three commands.
Thanks,
Guangde

Where can I find Labview drivers for the RSA 3308A Spectrum Analyzer

I need to use Tektronix's Spectrum Analyzer RSA 3308A as a LabView environment
instrument for my school project, I would like to know if there are available
drivers, if no drivers are available which are the implied software/software
requirements to achieve this goal.

NI doesn't have a driver and I couldn't find one on Tek's web site. That seemed kind of strange to me so you might want to contact Tek directly and see if they have something. If that comes up blank, you have several options. LabVIEW has the Instrument I/O Assistant (on the Instrument I/O palette), that will alllow you to create a series of writes and reads to an instrument and parse results. The assistant lacks flexibility but if your needs are fairly simple, it might be all you need. Of course, you'll need to be familiar with the instrument's command syntax. A step up the assistant is to use a series of VISA Read and Write commands. These would commands similar to what you would use with the assistant - tailored specifically for your application. You gain some flexibility because you can easily vary the command parameters with LabVIEW variables. At the top of the complexity ladder is developing a full blown instrument driver yourself. NI has some great tools to make this easier than it has ever been before. The guidelines and links to the tools can be found here. Lastly, you can request that NI develop a driver here. There is no guarantee the they will develop it as they base that decision on things like how many requests they get for a particular instrument.
