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.

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?
Tzviel

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!

Agilent ESA Series Spectrum Analyzer (E4448A) - Can not initialize.

I have downloaded the drivers for the Agilent ESA series Spectrum Analyzers from NI and I am having trouble just running the initialization VI.
I am currently trying to run the VI called: agesa initialize With Options.vi on Labview 7.0 Express
This is the error I receive:
agesa Initialize With Options.viDriver Status: (Hex 0xBFFF0015) Primary Error: (Hex 0xBFFF0015) Timeout expired before operation completed.
It looks like the Spectrum Analyzer does do a few things (Changes Carrier Frequency to 50 MHz), but it's getting hung up somewhere else.
If I highlight execution, the error comes out of the Call Library Function Node elaboration output in the aforementioned VI.
Here are the settings of the VI I have:
Settings:
id query: true
reset device: false
Option string: Simulate=0,RangCheck=1,QueryInstrStats=2,Cache=1 (The default)
Resource Name: GPIB0::16:INSTR
Any help anyone could provide would be appreciated. Keep in mind, I am fairly new at this. Thanks.

Well, I don't seem to have that option on the E4448A, here's what i do have:
System -> Config I/O ->
GPIB Address
IP Address
Host name
Subnet Mask
Gateway Address
SCPI LAN
Under System -> Config I/O -> SCPI LAN ->
SCPI Telnet
SCPI Socket
SICL Server
None of the above stuff seems applicable if I am only using GPIB?? I tried modifying some of the options above, didn't seem to help.
Here's some more information in the Error History on the Spectrum Analyzer:
-420, Query UNTERMINATED, &ltErr>
-113, Undefined header, :BAND:&ltErr&gtRES:AUTO?
The above looks like #21, and the error, #22, is right after it. Any idea what that means?
I'm going to try it on another computer... More to come!

Spectrum analyzer or spectrum viewer on garageband

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.

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...
Enjoy...

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

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.

I have got about 8 to 10 DC's out of which only this one is showing the missing structure and as this dc is being used by other dc's I am getting the error like missing component. Previously we were using the client desktop and doin the work now we have shifted it to our individual systems. Now any project I am creating whether from same track or different same problem comming the structure is missing.

"agesani Initialize With Options" timeout error on HP E4401B spectrum analyzer

System: Windows XP Pro, LabVIEW 7.1, IVI Compliance Package 3.0, NI-VISA 4.1
I have an HP E4401B Spectrum Analyzer. I'm trying to write some LabVIEW code for it, using the agesani.llb library.
When I try using the agesani Initialize With Options VI, I get the following error:
Error code: BFFF0015
Source: agesani Initialize WIth Options.vi<ERR>Driver Status: (Hex 0xBFFF0015) Primary Error: (Hex 0xBFFF0015) Timeout expired before operation completed.
I've searched the NI Knowlege Base, and haven't found anything that seems useful. What I _have_ found are the following items.
Knowlege Base article "Time-Out Error with the Agesa Instrument Driver Example". This refers to the agesa drivers, not the agesani drivers. It also references an E4440A spectrum analyzer, not an E4401B. The article says one cause could be that a compatibility mode other that SCPI is in use. While the articles says how to fix this on an E4440A, the fix does not appear to apply to the E4401B. In fact, if it is even _possible_ to have a mode other than SCPI on an E4401B, I can't figure out how to do it. A second possibility the article suggests is that the spectrum analyzer is in Phase Noise mode rather than Spectrum Analyzer mode. My E4401B is in SA (spectrum analyzer) mode. I don't even see a way to put it in any other mode - I don't think the required options are installed. Finally, my VI is configured as the article states - ID Query YES, Reset Device YES, etc. I should note that the instrument's GPIB address is 18, and that this matches the resource name GPIO0::18::INSTR.
Some additional information: The spectrum analyzer's screen is indicating the instrument is in Remote (R) mode as a Talker (T). A "Query UNTERMINATED" error message appears at the bottom of the instrument screen.
I've attached the results of a NI Spy capture to this message. (At least, I think I have. I've never tried doing this before, so if it doesn't show up, would some kind soul tell me how to include an attachment to my post?)
Oh, yes. The agesani version is driver version 1.1, updated 17 Aug 2007. (The version that's currently on the NI download site.)

Hi MXI Master,
If there's an instrument timeout, I haven't been able to find it yet. Seems like there should be, so maybe I just haven't looked in the right place yet. As for the timeout value on the computer, I'm not sure what you mean by this - could you elaborate, and maybe tell me where to find it?
As far as SCPI mode, if it's possible to put the E4401B in something _other_ than SCPI mode, I haven't figured out how. I can't find any support in the programming manual for anything other than SCPI.
That kind of seques into my next couple points. The NI Spy output indicates that one of the commands that is being sent is "*SRE 32".
The "User's & Programmer's Reference" for the E4401B says (on page 206) "Send the *SRE <number> command (where <number> is the sum of the decimal values of the bits you want to enable plus the decimal value of bit 6). [Bit 6 is the Request Service (RQS) Summary Bit. BP] For example, assume that you want to enable bit 7 so that whenever the operation status summary bit is set to 1, it will trigger a service request. Send the *SRE 192 (128 + 64) command."
This statement would seem to imply that the "*SRE 32" command that is being sent by the agesani "Initialize With Options" command is an illegal command, or at best an ineffective command. In light of that, it is interesting to me that the NI Spy output indicates that the next line , viQuery(GPIB::18::INSTR (0x246E9C8), "%s?","%ld"), is generating an 0xBFFF0015 error. In addition, I can find neither the "%s?" nor the "%ld" commands listed in the Programmer's Reference. I wonder if these could be for a firmware revision later than mine (A.01.03), or for instrument options I don't have (A4H, A4J). Alternatively, I wonder if these are simply mistakes.
The next line in the NI Spy output, Formatted viWrite(CPIB0::18::INSTR (0x0246E9C89),"INST:NSEL?",11,11), also puzzles me. The Programmer's Reference indicates that this is a supported command, to see what instrument application is currently selected. (e.g. spectrum analyzer, GSM, Bluetooth, EDGE, noise figure, etc.) However, when I try to issue this command to my instrument, by using the Instrument I/O Assistant Express VI, I get an "Undefined header" error on the instrument's front panel. The instrument's error history shows the same "Undefined header" error. Since my instrument only has the basic spectrum analyzer option installed, I wonder if this command is not valid? (Personally, I wouldn't write instrument firmware code this way, but who knows?) Alternatively, I wonder if this command requires a firmware revision more recent than mine. (The Programmer's Reference is silent about this possibility.)
The next line in the NI Spy output, Formatted viRead(GPIB::18::INSTR (0x0246E9C8),"",4000,0), has another 0XBFFF0015 error associated with it.
Does this information shed any more light on the situation?

Can I view the names of chords I've already laid down?

I made some versions of some old time fiddle tunes to occompany myself when practicing. Recenly I had a real live guitar player to accommpany me. He asked "how to the chords go to this song?" I said, "I don't know, but I already laid down a smart guitar, smart bass, and smart drums for the song in GarageBand. You'd think I could tell by looking in GarageBand." When I look at the "Instruments" view of the song, I can see the little green bars on the smart guitar line like a piano roll, and see the pattern change where the chord changes, but can't tell what the chord names are. Is there any way to get GarageBand to show me the chords I've already figured out to remind me or show a guitar player during a session.?

GarageBand does not show the name of a chord - you could try spectrum analyzer software that can unmix and analyze music, like TransScribe!, for example.
Otherwise you will have to do it the hard way and compare the the chords in score view to chord tables, to find out what they are called.

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

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.

Spectrum Analyzer using Swept Frequency

Using the AWESOM example foundhere:
http://zone.ni.com/devzone/explprog.nsf/6c163603265406328625682a006ed37d/433c2cbc5a1c4a49862569500035f715?OpenDocument
Give the person who wrote that an A+. I want to replace the FIR filter with a REAL device. I want to send a swept sin wave (just like the original) and then read the response from the Analog Input channel. I put a vi in place of the vi called :IIR Filter for 1 Chan.vi. Go to the NI ftp site to ge t the file named ZZDMKSin.zip (I could not get the file attachment to work within this post) The symptom is the Frequency Response does not get any data that can be seen...
In the end I simply want to put a REAL UUT in place of the FIR filter. This would turn the VI into an equi
v of a $30,000 spectrum analyzer! Sooooo cool!
Any help would be greatly appreciated. My e-mail is [email protected]
Thanks,
Dave

Dave;
I'm not quite sure if I understood your application, but by my understanding you want to replace one of the Filter VIs by a VI that does data acquisition from a real external device.
The first thing you might want to double check is the data acquisition VI by itself. Set up the system with the external device and with the data acquisition VI only. Make sure the VI is acquiring data as expected.
After that done, make sure that the data acquisition VI output is outputing the same data type that is expected at the output of the IIR Filter.vi.
I believe that either one of the previous issues might be the answer.
Hope this helps.

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:

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.
