possible bug in Agilent ENA series LabVIEW Plug - and - Play (project-style) Instrument driver

think I found a bug in this driver and I wanted to get confirmation.  (Here's the link to the driver page, to help locate the driver):
( http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=74D1F1D4EB5268E8E04400144FB7D2...)

The VI in question is public > Action-status > configure > marker Configuration > Configure Marker.vi.

The question that I saw was that the marker was not be set to the frequency transmitted to the VI.  (The parameter named 'Stimulus'.)  I looked at the guide to the programmer for the Agilent 5071 B and decided that the format of the SCPI command string should probably:

%.;:Calc%ld:Mark%ld %s;
: CALC % ld: % ld MARK: X % lf

The ": X" had disappeared but seems necessary.

Can this be verified?

Thank you for taking the time to look at it.

Snood1,

I took a glance at the driver and manual of the programmer. It seems to me that the driver behaves as described in the manual should. Configure the Marker.vi use the following string to format the command:

%.;:CALC%ld:MARK%ld %s;
:CALC%ld:MARK%ld:X %lf

Is that what you see too? Looks like that's what you added yourself. What was the previous text? This is the text that was there when I downloaded the driver. When it is interpreted, it looks like this

:CALC1:MARK1 OFF;
:CALC1:MARK1:X 0.000000

As described in the ENA series Programmer manual, the first turns of the line of the marker reads OFF (page 283). The second line sets the value of the marker 1 (page 295) stimulation.

Let me know if this looks OK to you.

Kind regards

  • Agilent 4156 new driver plug-and-play (pulse-installation problem)

    Hello, I am new to Labview and just started using the Agilent 4156 new plug-and-play driver published on 02/12/2008. I try first to set up conditions of STRESS using this project. While I am able to configure most of the things that I need, I can't set the peak pulse value using the program "Set Pulse.vi". The Readme for the driver mentioned that this program has not been tested. The error message is the following:

    Reports of the instrument:
    + 181, "illegal installation. Invalid command. »
    -113, "undefined header."
    + 0, "no error".

    Can someone help me with this problem?

    Thank you.

    Thanks for your reply.

    I think I solved the problem. There are syntax errors in the "set up" Pulse.vi (PUL has been used instead of PULS in two places). He is now able to set the basic and advanced.

    In addition, the way is designed the vi, it will always give an error because he tries to put in tension (possible only when a VIEW is of type V) 'Source' and 'Base' / 'Peak' tensions (only possible when the PGU is a type VPULSE). I removed the parts that I didn't need.

    FYI, I use an Agilent 4156 C. In the configuration screen, the revision of the CPU is 1 and the revision of the software (03.06 HOSTC, CUMS 04.07, ADC 01.00).

  • Plug and Play drivers: Instrument of Identification error (pumps Ultra PHD at Harvard)

    Hi all! I use the LabView drivers to control a unit of Harvard pump 70-3007 and fall on some issues. (I'm controlling through the USB port).

    Driver:

    http://sine.NI.com/apps/UTF8/niid_web_display.model_page?p_model_id=16026

    Plug-and-Play site:

    http://www.NI.com/white-paper/3271/en/

    So I downloaded and installed the drivers and made sure that I have ALL the necessary software (USB virtual COM and VISA) installed. I then used teraterm (serial port communication software) to make sure my computer can communicate with the pump. He could.

    I then moved in labview, to make sure that my computer can control the pump. He couldn't. As soon as I try to screw attached with the drivers, I get an error. The first step in each VI is to call an Initialize.VI that makes a 'Identification of Instrumentation' stage, which always generates an error. He tells me that either I have wrong COM port (I assure you, I did not) or that the instrument drivers are not updated. HM.

    Any ideas? Of course, I know probably no one here has used this series of pumps before, so if there is no additional information / screws I can join, please let me know.


  • Confused and IVI compared with plug-and-play instrument drivers

    I'm just going up to LabVIEW and see that when I go to download instrument drivers, there are several lists.  One is a Plug-and-Play and the other is typically IVI.  What is the difference?  So far, I've been through the course of the lesson no. 1 and lesson #2 Basic Developer, but we have not touched on the use of the downloaded drivers.

    IVI: Interchangeable Virtual Instrument. With the help of this software layer allows the developer to work with an independent 'generic instrument' of the manufacturer (e.g. Agilent DMM VX OR DMM).

    Plug 'n' Play driver: the driver for the same instance of an instrument, necessary for the operating system to identify and drive the instrument. The driver is device-specific.

    hope this helps,

    Get a Blue Screen of Death: Plug and Play detected an error, probably due to a bad driver?

    I'm running on Windows Vista Home Basic. I don't know what happened, but this morning when I turned on my laptop Dell Inspiron 1420, the blue screen of death appeared saying that "Plug-and-Play detected an error, probably due to a faulty driver. She also asked me to 'Disable the BIOS memory options such as caching or shadowing the' but I don't know how to do this, because it does not appear on my BIOS settings. In addition, the message suggested that I go on safe mode, but whenever I try to go on Safe Mode, the Blue Screen of Death keeps re-appearance, so I can not go on Safe Mode or the other. And one other weird thing is that when I press F8 (press the key to early startup options) I get to select an operating system to start: Microsoft Windows XP Embedded which is weird, because as I said, my OS is Windows Vista and I don't have any other OS installed in my laptop.

  • Windows XP SP3 USB errors / unknown devices with Plug and Play

    I have problems with USB flash drives and other plug-and-play devices detected by windows. After taking all possible measures to correct this problem (e.g. windows update, chip / update of the bios, update driver, driver and media ultilites reinstall, uninstall and allow windows update after restarting, removal of hidden devices and even remote tech support from Dell) whenever I connect a flash drive or use all plug-and-play devices it is detected as an unknown device and I can not put updated pilot any port I use. Hardware problems were excluded dute to recognition of the device and USB keyboard and USB mouse are functioning properly. Also these same plug-and-play devices worked well on other items of work. After Googling my eyeballs, I gave up and need help please. The only thing I can do now is to reinstall the operating system that really, really, I don't want to do.

    UPDATE *.

    Dell has replaced the motherboard and the problem was solved. Thanks to all here who offered advice and patience.

  • Plug-and-Play drivers MIDI does not

    So, I recently bought a Vestax VCI-100, which is a feature of MIDI USB plug-and-play. Connect to my PC, it runs the dialog add new material, looking for drivers. After awhile, he gives up and says that it cannot find the drivers, which is strange because the device is supposed to be plug-and-play. It also happened a while back with a MIDI keyboard USB Generic. However, I have a keyboard more advanced (a M - Audio Axiom 49) that has its own custom driver that works very well. It's almost anything requiring the drivers of default plug-and-play MIDI which doesn't seem to work.

    What I discovered in my own extensive research, is that often this problem is caused by drivers Logitech Webcam creating inappropriate filtering at a level of register (my terminology may be a bit off here, lets say that I am an "intermediate" user). Unfortunately although I've never installed Logitech Webcam driver and I scanned the registry and cannot see any sign on the suggested potential cause.

    I also note that user; http://social.answers.Microsoft.com/forums/en-us/w7hardware/thread/8d33026c-f5a7-4fe2-8839-6cbdb04c5d6f complain of similar problems, that he believes was caused by its instalation of ProTools. Too, I have Pro Tools on my machine and during the inspection, Miss me the file "wdma_usb.inf". However, my Pro Tools installation is up to date, but the file is still missing.

    It is by far my best leader on what is causing this problem, but I don't really know yet. I would avoid a complete reformat if I can help it, but I can't find a reliable source for the correct version of this file. Can someone provide me with this file an instructions on how to install it? In addition, advice or suggestions are more than welcome.

    Thank you in advance, this has been frustrating me for quite awhile.

    Hi, Ben Murphy,.

    I found the following information on the site Web of Vestax:

  • How can I reinstall the non-plug-and-play drivers that I have uninstalled mistakeningly?

    I have a Dell Inspiron and recently started having random blue screens, close down and the inability to get out of hibernation with her. I ran Microsoft Security databases, and he is found to have viruses Alureon.A, whom he said he eliminated, but when running - it again, it was in Quarentine. Tried to get into SafeMode w / networking to remove and it quarentined again. Return to normal and it works, it shows up again!
    I did some research on Google and found another way to remove it by devmgmt.msc and could not find the file that it supposed to delete. A next post had a list of non-plug-and-play drivers, and I misread this post and uninstalled the files he had. Reading - it a second time, they were not the drivers to uninstall! So now I uninstalled the drivers, that I should not have, and I'm afraid to turn it back on. What should I do? Is there anyway I can get these drivers or is it easier to reinstall Windows Vista all together and fix the drivers and get rid of the virus?

    I was also unable to update Windows with this virus, with MSE.

    Accidentally uninstalled files were:
    A sound signal
    HTTP
    NDIS system driver
    NDProxy
    Null value
    RDPCDD
    Remote Access Auto Connection Driver
    VgaSave

    First of all, I recommend you download and run the program below.  It's the only one I found that systematically identifies and removes infections Alureon.

    http://support.Kaspersky.com/viruses/solutions?QID=208280684

    So, I see two possibilities. Sfc/scannow in an elevated command prompt might reapair missing files and is worth a try.

    If this fails, try the system restore.  It is a risk and could fail and possibly further damaging the system.  If If is running it will probably restore the infection as well.  In this case, restart TDSSKiller and other malware analysis.

    Although I always discover a wipe and reinstallaton ultimately, it may turn out to be necessary in your case.

  • Plug-and-Play and DEP stop computer

    Randomly, my computer tells me that there was a problem with the Plug-and-Play and Data Execution Prevention must shut down and restart windows.

    Hello

    You could try a system restore before it starts HOWEVER I wouldn't back to. better to solve
    the question because if you perform the restore you may lose the changes you have made and the problem is likely to
    come back. The onlyreason I mention this so that you know the possibilities if someone else
    He suggests here or via other communications you might try. System Restore is ok on some points, but
    last resort for this one.

    The problem might actually be an add-on or another program to the origin of the problem and you should check that
    1st.

    What antivirus/antispyware/security products do you have on the machine? Be one you have NEVER on it
    machines, including those that you have uninstalled (they leave leftovers behind which can cause strange problems).

    You said Norton and it could well be part of the problem. You others have on this machine EVER?
    (Windows Defender and MRT Scanner are fine).

    Start - all programs - Accessores - system tools - IE with no Addons - does this work better?

    IE - Tools - Internet Options - Advanced - tab click on restore, and then click Reset - apply / OK

    IE - Tools - Internet Options - Security - reset all Zones by default level - apply / OK

    not better?

    Close IE and try again IE or IE with no Addons

    IE - tools - manage Addons (for sure disable SSV2 if it is there, it is no longer necessary but Java always install
    "(and it causes problems - you never update Java to go back in and turn it off again)." Search for other possible problems.

    Windows Defender - tools - software explore - look for problems with programs that do not look right. Permit
    are usually OK and "unauthorized" are not always bad. If in doubt about a program to ask about it here.

    Could be that a BHO - BHOremover - free - standalone program, needs no installation, download and run - not all
