• Agilent E3640A PSU with GPIB-USB-HS

  Hello all, I created an Agilent E3640A power control software standard interface GPIB. It works very well. Now, I want to replace the standard GPIB interface (with GPIB card) with GPIB-USB-HS adapter cable, so that I can send commands via USB connection, eliminating the need for GPIB card. How can I use my existing application to work with GPIB-USB-HS adapter cable? Is this a change? or I completely rewrite the code, and if so, are the drivers available for GPIB-USB-HS adapter cable? Thanks Jeet

  More information please.

  Have you removed the PCI interface before you try the USB interface? If this is not the case, your program may still try to access the E3640A on the PCI card.

  What is the USB HS recognized in Explorer measurement and automation as GPIB0?

  The E3640A knows if scan you for Instruments to MAX?

  What (number) error is raised during the execution of your program with USB HS?

  It would also help if you could show us NI SPY logs saved when executing your program with PCI and USB-Interface Card

  Usually you don't need to install different drivers, because the package NOR-488. 2 installs drivers for all variants of the NI GPIB hardware.

• Synchronization and optimization of keithley-Labview with GPIB-USB

  I started an old thread on this subject, but I have some new problems. My vi is to control a Keithley sourceMeter to read measurements every 5 ms for 6 to 10 hours, using GPIB-USB. The vi simply sends the commands under a full script to the instrument and then bed measures (voltage and current) in a loop using the visa and saves the data and displays them in a second loop using a queue. I decided to use a queue and a second loop due to the delay caused by reading data, save them in a file + display, all in a single loop! I want to be able to see all the data with real time axis, so I used a xy chart.

  Having a shorter time in the upper loop isn't a bad idea.  Using the wait until the next ms multiple rather than just the Dequeue wait time can cause the occasional time jumps.

  I have no LV open now, so I'll try to remember your VI.  I think you picked up 3 data values and a timestamp of each 5 ms.  It is 800 items every second. If you want to save all the data but only write to the file every 5 seconds, you will have to accumulate 4000 items. Because file entries are not always made exactly when you ask them because of the behaviour of the OS, you must allocate a bit more wide open spaces.  You can initialize an array 2D as 1200 X 4 (1200 lines of 4 columns) of NaN. Place this table into a shift register.  Every time you Dequeue data, replace the next line with the data.  When you write to produce, use the subset of the array to get the part that was replaced with real data and write the part in the file.  Return the initialized array of NaN in the registry to offset and continue to replace the data.

• Connection of an instrument with GPIB-USB connection.

  I am trying to use a GPIB-USB adapter to control a unit of Source of LabView. However, I have problems my instrument drivers to recognize the GPIB address specified for the device. I have attached an image below the address specified by IO Keysight connection Expert. I am currently trying to initialized the EMS with the GPIB driver I have attached below. Because of my knowledge limited in LabView instrument control, how should I approach of collecting the correct address of GPIB and recognize it in my VI?

  Hi wyattcurtis824,

  Before we dig into the LabVIEW code, I would recommend a Test Panel of max aperture and trying to communicate with. Are you able to send orders via Keysight connection Expert or NI MAX and see the valid data?

  In addition, when you run the vi in LabVIEW, is pilot it returns an error in the error on the box? If so, what the error is?

  This shoule information help us to the root of the problem.

  Best,

• How to use traditional nidaq with a USB-GPIB installation

  Hello

  When I tried to install the interface GPIB-USB on my computer it tells me I must uninstall nidaq traditional, but I need nidaq traditional also.

  Is it possible to have both installed and functional? Is there a work around?

  Help, please... Thank you

  Darryl Huggins

  Thank you for your response Dennis,

  When I went back to look at the message I think he wanted me to uninstall a driver inherited NOR-488, so I advanced and uninstalled.

  But he said traditional legacy of NOR-DAQ. I was unable to see my card GPIB with Max is why I wanted to install the USB-GPIB.

  After installing now I am able to see the card GPIB and USB-GPIB interface. Must of had a bad driver, I suppose?

  So now I will run another test to make sure that NEITHER-traditional DAQ still works also. But so far so good.

  Thanks, Darryl

• Driver for Keysight 34461 A DMM instruments works with GPIB, errors with USB

  I try to remotely control a DMM of 34461a Keysight using the driver of instruments located here:

  http://sine.NI.com/apps/UTF8/niid_web_display.model_page?p_model_id=21589

  The pilot of the aircraft works like a charm the DMM is connected via GPIB, but it error when connected via USB.  I've isolated the problem to "Default Instrument Setup.vi".  When this VI is called in the case of USB, the device is left in a State which translates by a later call a time-out at VISA Read.  The only way I found to get the instrument still talking after this occurs error condition is turned off.  I have an another 34461a with the same behavior, is probably not a hardware problem.  I can successfully run the example 'Agilent 3446 X series Acquire Single.vi' via USB if I remove all calls to "Default Instrument Setup.vi.

• How old, a driver can be used with the USB-GPIB controller?

  Hello, I have a litter of Nicolet who I'm trying to control using an NI USB-GPIB controller and a Nicolet provided the program. The software were made in 1995 and told me it was made to work with the NI AT-gpib cards and I would need to use a pilot more OLD, BUT I don't have access to one of these cards for a purchased a USB-GPIB, hoping that it would work. A pilot more FORMER will support the GPIB-USB?

  Sorry for you, but not

  This is a really old software and works only on the driver to the gpib.

  Written in LabVIEW software would go from before this date.

• E4407B works not with NOR-GPIB-USB-HS

  My E4407B Agilent does not work with my NOR-GPIB-USB-HS. I tried two different E4407B Agilent and 2 different NOR-GPIB-USB-HS, so I doubt it's different devices. The E4407B will not be displayed in the solutions of measurement and Automation Explorer. I tried fiddling with the matching settings listed here, but without result. What I need to make this work? I spoke in support of agilent and they claimed it wasn't my NOR-GPIB-USB-HS, settings on the Analyzer.

  Nevermind, I figured it. The NOR-GPIB-USB-HS is apperently not make good contact with GPIB port on the monitor, even if it is screwed to the bottom. I plugged the adapter to a GPIB cable, then GPIB cable to the parser, and it worked fine.

• Agilent 82357 B GPIB/USB, problem with distributed applications

  Hello everyone,

  I am developing software that communicates with an instrument, with USB, RS232, Ethernet and GPIB interface

  On my development PC, I can communicate with my instrument using a 82357 B Agilent GPIB - USB converter, without any problem. (and other interfaces as weel)

  I have deployed the application using the Installer application on the target computer Builder. The application works with USB, RS232 and Ethernet interfaces, but I don't see the GPIB interface in the control of VISA resource name.

  I followed the advice given by OR when you use a converter USB GPIB of Agilent (Tulip active...)

  I did the following tests on the target computer:

  -J' installed MAX, and I can communicate with the VISA test panel using the GPIB-USB converter.

  -J' made a small application with the VISA resource find included

  -If I unplugged the converter USB/GPIB instrument, the VISA to find the function return resource: GPIB0::INTFC, COM3, COM4, LPT1 COM7

  -If I plug the converter to the instrument, the function of resource VISA finds return nothing.

  -If I run the interactive command of VISA, I got the following error:

  Cannot find the resource by using expression? " »

  error: BFFF003A

  Name of the State VI_ERROR_INV_SETUP

  I'm using LabView 8.5 under windows XP.

  I have included in the installer

  -Run LabView 8.5

  -VISA 4.4 duration

  The target computer is running Vista.

  Thanks for your help and your support.

  Hello everyone,

  For your information, I have solved the problem in desinstalling then reinstalling my installation software on the target computer.

  I still don't know where the problem was, but it's working now. (even with the version of the driver 15.0 agilent)

  Thanks anyway for your help.

• Interface and installation of my instrument with lab view and keithely, GPIB-USB-HS

  Hai...

  We have 236 Keithleu and software vision lab and GPIB-USB-HS. I had the GPIB software installed is OR-488. 2 3.1.1

  Now, I had the indication like that.

  1. in Kethely no indication

  2. in GPIB +'s got orange led in ready icon.

  3 but if I runt the program I found no results.

  So can you me the interfacing of the keithlye and alo for the GPIB and also computer.

  Regads.

  The pilot here can help you. I suggest you first learn how to set up the action manually. Then study the programming guide to understand what commands you need and the settings for them. Good luck.

• Driver XP GPIB-USB-A has not installed with NI488 - 2.8.1

  I have the DVD driver for August 2011, and I installed NI488 - 2.8.1, which should have the GPIB-USB-A driver in it. I plug it in, and Windows cannot find the driver for it. Is there a specific folder, I do so he could find the driver?

• Question of GPIB-USB-HS

  Hello everyone, I have 5 machines hooked: set of 2 meters, which connect to a power supply that goes to a function generator and led to a thermostream which then my GPIB-USB-HS is used to hang my computer. I am running an executable file from a previous VI, I tested on the computer that has the original VI. I have the correct runtime downloaded, and I can open the VI. There isn't an arrow broken for the execution button, but when I run it, it immediately stops running as if the VI running, but nothing happens. No errors or messages. It's as if nothing does not communicate. So my first instinct was to control the GPIB. They are all tight, and I checked to see if maybe the instruments were not recognized by the GPIB-USB-HS, but MAX watch I have all 5 connected instruments when I 'Search tools'. On the GPIB-USB-HS, there are a light yellow/orange on the loan and nothing on the assets. The GPIB correspond all too much, and the address for the GPIB-USB-HS is set to 0.

  Thank you.

  You can create the exe with active debugging and place probes to determine what is and what is not running.

  Also, you don't mention if you have installed the runtime of NI-VISA.

• OR GPIB-USB-HS + NI GPIB-USB-HS vs

  I have a visual basic program 6 which measure IR using a meter of high resistance of agilent 4339 B.

  The existing work PC running Windows XP and use the NI GPIB-USB-HS and works very well.

  The original code uses the 32-bit Visual Basic Language Interface Version 1.7 of National Instruments with the DLL of NOR-488.

  When I try to use the NI GPIB-USB-HS + controller it does not work. I installed the new driver for the NI GPIB-USB-HS +.

  I uninstalled the driver and returned to the NI GPIB-USB-HS controller and re-installed the driver appropriate for her and the program works.

  I tried to implement the same program on another PC and could never get the program to communicate with the tester using the

  OR GPIB-USB-HS + controller.  That is when I decided to check the controller has worked on the original PC and discovered that it is not.

  I also had the same problem with communications with the bridges of cap and had to re - write programs using NI-VISA that the

  OR GPIB-USB-HS + works fine when with.

  I would have thought the NI GPIB-USB-HS and the NI GPIB-USB-HS + both work on the same application without any

  code changes just and necessary update the driver.

  I thank in advance for any help, you can provide on this subject.

  Thanks - I made some progress on that yesterday.

  It turns out that the initial program had the primary address of the hard coded device.

  I added logic to get the main address of the device and I have replaced the hardcoded with a variable value.

• GPIB-USB-HS and USB-8451 communication issues - appearing only in VISA

  Hello

  I recently started a new job and have had communication problems between my adapter GPIB-USB-HS, my VISA or MAX-Labview and USB-8451 I2C/SPI interface.  I installed LabView to 32 bits, OR-488. 2, the driver for the 8451 on my windows desktop and VISA 16.0 7.

  In the windows Device Manager, the 8451 appears as a device USB of NI-VISA and Gbspecifications FOR-USB-HS presents itself as a GPIB Interface of NOR.  Two of these instruments are recognized NI Max so but communication Gbspecifications FOR add-in adapter (and connected instruments) fails and he can't find the instruments and the self-test fails with a hardware error unknown gpib (-37052).  The watch also neither device VISA Interactive Control.

  The ready light is lit on the GPIB-USB adapter and the 8451 flashes green as if nothing is wrong at the end.  I uninstalled all the software of NOR and reinstalled, and I run MAX as an administrator.  Is there possibly some computer settings I could neglect or need to change to open a communication?  Any other ideas on why I can't communicate with devices?

  Thank you!

  This is a device-Lock software that my it was preinstalled on the computer blocks the USB port.  SHE has added features like confidence, and now it works.
