• 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,

• Data acquisition using the USB-GPIB 82357 B interface for 4395 impedance Analyzer has:

  Hi all

  I tried to communicate Analyzer 4395A impedance with interface USB GPIB 82357 B using the command of expert keysight and Labview module tutorial. I couldn't able to find orders of SCPI (Standard for programmable Instruments orders) for 4395 A impedance Analyzer in the expert keysight command. Please help me on the subject of what are the other possibilities to acquire data from the Analyzer of impedance 4395 A using the interface USB GPIB 82357 B.? Is it possible to get LABVIEW plug & play drivers for USB-GPIB 82357 B interface? Our main goal is to control the parameters of impedance measurement and draw F vs IZI and theta vs F as well as get parameters of equivalent circuit on a PC with LABVIEW GUI.

  Can't wait to help.

  Hello!

  I agree with 'heavy '. For more information on how to program a 3rd device contact the manufacturer because they have the knowledge. Unless there is already a LabVIEW driver for this device, you would have to implement that yourself and need information from the manufacturer.

  Regarding your question if the GPIB-USB is unsuitable, it is quite easy to answer: If you want to communicate with a peripheral GPIB NI GPIB-USB can do this. But you would probably need a driver to use the GPIB of meaningful communication bus.

• Connection of GPIB USB HS TWO agilent instrument (power)

  Hello

  I'm fighting to control two power supplies (E3631A) Agilent using GPIB USB HS connection.

  But they are not detected as TWO different power supplies regardless of STAR or linear connection.

  However, when I try to set up a power source and a Tektronix oscilloscope, they are considered TWO different instruments.

  Single power supply control is also OK.

  So, I'm wondering how to set up TWO power supplies.

  I enclose the code VI to not control than a single power supply and want to extend to the version of the two instruments.

  you have configured the power to two addresses different gpib?

  This is needed!

• Can I use a USB hub to connect to more of a GPIB-USB-HS USB ports?

  I have an instrument that has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple computers to connect with USB hub in their respective USB ports? If so, how many computers can I connect using the USB cable?

  I downloaded the latest Driver NI-VISA from the Web site.

  You must first a hub which allows to switch between multiple PCs and PCs as one would at once be connected and in control.

  When you buy this particular type of hub, one of the specifications is how many pc connections there.

• MAX does not detect my instrument 488.2 GPIB-USB-HS, but Windows XP Device Manager only

  Hello

  I have a problem when you use the 488.2 GPIB-USB-HS, I see the device in Windows XP Device Manager, but it is not visible in the MAX, I do not see even a section for devices GPIB. However, when I try to install a new device, GPIB, the Wizard MAX tells me that it is one of the instruments GPIB installed on the computer which GPIB0 - USB-GPIB-HS. Do you know what is the reason to do this, because I want to use a multimeter in LabVIEW via GPIB, but I can't access it, I don't even see that there is a GPIB connection in the computer (in LabVIEW).

  Kind regards

  It's the kind of old. Have you tried the last?

• How to connect several GPIB-usb-hs instruments?

  I want to know how can I connect several instruments and acquire their signals with a GPIB-usb. I m using 2 multimeters, 1 temp. controller and 1 power supply and I have all the drivers I need. I just need to gather all the drivers 1 prog. to control via GPIB. I have 1 gpib-usb-hs, but I need to read that data from those equips. Any help and advice are welcome.

  Thanks in advance.

  No, what you're asking is done all the time. It must just be a little careful about the management of your written and reads as in most cases, you can connect to only one instrument at a time.

• GPIB-USB-HS will recognize any instrument in LabVIEW but somewhat done in MAX - help

  Hello

  I'm having a problem getting my GPIB-USB-HS device to recognize instruments in LabVIEW.  The unit has been running year last on many instruments.  I tried the GPIB-USB-HS other materials too just to make sure it wasn't a defective unit.

  NOTE: I installed the latest drivers for NI-VISA 5.1.1 and 300 of NOR-488. 2 for Windows XP

  See the images below:

  It's the idsplay to the MAX:
  I'm not sure why there is a yellow "!" next to GPIB0::INTFC, I think it's an indication of my question.  However, note that the instruments connected to my GPIB-USB-HS are counted in MAX.  As you'll see LabVIEW 8.5 does not recognize them.

  

  I get this error Max warning when I try to open TOOLS > NI-VISA > VISA INTERACTIVE CONTROL:

  

  It comes to the image of my LabVIEW 8.5 window when I try to select a VISA of an instrument (including MAX recognizes):

  

  Any help would be much appreciated

  Thank you all for your help,

  Problem solved after hours of uninstallation and reinstallation of all devices/software from National Instruments.

  Once all programs have been uninstalled (with a disk cleanup on my unnecessary hard-maybe records)

  LabVIEW 8.5.1 has been reinstalled

  NOR-DAQ has been reinstalled

  NI-Visa 5.1.1 has been reinstalled

  NOR-488. 2 worm 2.7.3 has been re-installed (correctly)

  Now, LabVIEW recognizes all ports/devices and connects to the instruments properly once more.

  My question must have been installing LabVIEW 8.5.1 after already installing LabVIEW 2009.

  Somewhere during the installation of 8.5.1 - main post problem occurred.

  Thanks again

• Problem Keithley 236 control using a GPIB/USB cable

  Hello, I would like to use my PC to control Keithley 236 SMU to make some simple steps I - V (sweeping voltage and measuring the current). If you can give me some advice about my problems, I will be very grateful.

  Situation: I have a PC (windows XP) with labview 7 and 8.2 and 8.5 installed and a GPIB cable / USB a Keithley 236 SMU. I want to make very simple I - V measurements (voltage scanning and measure current). The GPIB-USB cable has already been installed on the PC to control some other Multimeters (voltmeters). Now, all these multimeters are deleted. The PC is connected ONLY to the 236 Keithley. The GPIB-USB cable status in green color.

  I downloaded a labview program adapted for Keithley 236/237/238 of Keithley Web site (home, 237 SwpMeasl - repeat.llb). But no matter how I tried, it cannot communicate with the Keithley...

  Do you know why? Any suggestion is welcome. I am a beginner in labview. Thanks a lot for letting me know.

  No, you cannot use the NI GPIB functions with a card of Agilent. You change using VISA.

• Using Agilent USB-> GPIB controller possible

  Hello

  When I have an Agilent USB-> GPIB controller so normally, I have to install the Agilent IO libraries for the windows driver.

  What should I do when I want to use the USB-> GPIB controller in Labview? There, I have NEITHER - MAX-> is the driver included in MAX or what I have to install both programs?

  thx for the help

  No, when you use a controller of NOR, you must NEITHER-488. 2. remember, the VISA is just one api that is above the actual hardware drivers. There is a specific hardware for the controller of Agilent driver and a driver of specific material for a controller OR.

  Where the driver is depends on your version of LabVIEW. On my 8.6 distribution, there is a separate DVD called NI Device Driver DVD.

• GPIB-USB-HS shows no MAX after that I used the wizard NI VISA DRIVER

  I accessed GPIB USB HS in the MAX software. As I was not able to communicate NF RLC remotely, so I tried Wizard DRIVER VISA OR according to tutorial Assistant pilot NI VISA , however, thnings went wrong and I am not able to see same GPIB to the MAX software now. What should I do now?

  The first picture below shows the GPIB USB HS as shown in the software MAX and the other image shows no GPIB USB HS.

  

  

  Yet once I installed driver USB GPIB link below:

  Its working fine now.

  Thank you.

• 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.

• 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.

• 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.

• Place HP 34401 in Local with GPIB-USB-HS Mode

  Hello

  I'm using LabVIEW 2010 SP1 to control the 34401 HP with the NI GPIB-USB-HS device. I use I/O built-in 34401 instrument drivers.

  If I plugged in everything, the 34401 will be immediately placed in "Remote" mode when I run my software. However, I would like to be able to use LabVIEW to force the 34401 to 'Local' mode Unfortunately I could not find a way to do this. I tried Close.vi, but has no effect.

  Here are my planned operation if it makes things clearer:

  1. Launch the software
  
  
  2. Initialize the 34401
  
  
  3. Place the 34401 in the 4W resistance measurement mode
  
  
  4. Pass the 34401 in "local" mode so that the end user can adjust a knob until the desired resistance is obtained while seeing the value of the resistance to change on the 34401
  
  
  5. Re-initialize the 34401 when I need to switch to another measure

  If not, is there a way to get the 34401 to permanently display how it is taken in remote mode?

  The feature I mentioned does exactly the same thing except that you have to do this awkward analysis of the address. It's a VISA function you have just used the search button to find (and have lit context-sensitive help) to obtain explanations of what he does.
