• 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.

• 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.

• 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.

• 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.

• 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?

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

  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.

• Beginner question absolute to the Labview with GPIB connection device

  Hi all

  Firstly, sorry if my question is already posted, but I tried searching with nothing doesn't.

  My situation: I have a HP digital osciloscope, a HP 54602 B using the GPIB and trial version of labview 8.6. Now, I want to communicate with her from labview. The big question is: how? Before that I used only labview with NI DAQ card and serial port for communications of the instrument.

  the detailed question

  1 is it important (to programming in labview later) what GPIB interface that I use in my computer? Must be of OR? I still have no interface right now.

  2. I ran a search on the osciloscope Web site of NOR and find an instrument driver in:

  http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=E3B19B3E93F7659CE034080020E748...

  . How do they come?

  3. I know there are a few examples for the GPIB, but since I do not have the interface, I can't try it. Is it possible to simulate instruments GPIB?

  Thanks for all your help and assistance

  Hi opiq;

  Welcome to the world of instrument in LabVIEW Control!  I'll try and answer your questions one-at-a-time:

  1. N ° from a point of view of LabVIEW, you can use any interface supported by VISA and your instrument bus.  This includes (but is not limited to) boards of NOR-GPIB, 3rd-party GPIB, USB, LAN, LXI, VXI, PXI, etc..  Of course, if you do not have a GPIB interface, I would recommend a NEITHER - this is the safest way to get the experience 'it works '.  I tend to use an adapter USB GPIB (DISCLAIMER - I work for the OR).
  2. You have two options for installing the device driver.  "" The simplest is in LabVIEW to select Tools "Instrumentation" instrument Drivers find... and use our instrument driver search tool which will be step helps you locate, by downloading and installing the driver.  The other option is to download the zip file, unzip it in \National Instruments\LabVIEW 8.6\instr.lib and restart LabVIEW.  So if you look in your palette of instrumentation, you should see the driver listed under instrument drivers.  The pilot will include some examples of the use of the driver (are all certified instrument drivers).

     In fact, I would recommend this driver rather than that you connected.  It is a more modern design and install examples in the viewfinder of the example ("Help" find examples...).

     Here's a video of the above process (for a different instrument, but the process is the same)

  3. Unfortunately, there is not an easy way to simulate this instrument.  I would just recommend familiarizing yourself with the examples before acquiring a GPIB interface.

• Watlow F4 with GPIB connection

  Hello

  I have a room that uses the Watlow F4 controller with GPIB connection. I want to control it by sending a recipe of Labview. I found this driver on the Web site OR:

  Not 100% sure it's the correct driver

  I intend to use a GPIB to USB converter. If anyone has a model of VI I could begin that would be great.

  Thank you very much

  LabView Newbie

  That looks like the correct driver.  Since it uses VISA, you should be able to use the serial or GPIB without having to change anything.  It should be an example in this driver as well as you could use as a starting point.

• Connectivity of VISA GPIB/USB Agilent 82357 B

  Hello

  Activation of the NI-VISA for Tulip Passport

  For software OR recognize the Agilent material, you must activate the Passport NOR VISA for Tulip. It is a software module that is included with NI-VISA for support of Agilent material and is not enabled by default. Use the NI Measurement and Automation Explorer (MAX NOR) to activate the passport for Tulip.

  In versions 3.0 and later of NEITHER MAX, you can do:

  Beginning NOR MAX
  Click Tools > NI-VISA > VISA Options...
  In the tree, select passports.
  Select the passport for the Tulip checkbox.
  Click Save to save the settings
  Output OR MAX, wait a few seconds and restart NI MAX (you must restart NI MAX for your changes to take effect).

  For details specific to your version of MAX to OR see documentation of NOR.

• Problem of earthing GPIB-USB-HS connecting to a laptop?

  Hello

  The installation guide for the GPIB-USB-HS asks to "ensure that the computer and the GPIB devices are at the same potential on the ground."  I was wondering if there could be problems with the connection of portable computers (because they float)?

  What should / could happen if the computer was at a different potential on the ground?  A short circuit?

  Where the potential of the Earth is different, the installation guide also mentions to use isolated a GPIB bus isolator/Expander or a USB hub.  I guess that laptop USB ports are "isolated" and so should be good.  Is this true?

  Thank you!

  Meister,

  Because your laptop is "floating" it's referance (mass to the chassis) has nothing to do with your referance of material (Earth) unless you take measures to link the laptop chassis to earth potential.  Attach a GPIB cable to your laptop and your equipment will provide a way to fulfil the potential difference between your laptop and chassis of the Earth through the GND signal on the Gbspecifications FOR bus.  The GPIB bus is not intended to carry large currents (great potential of discharge) and you can force entry on the laptop protection circuits or equipment when you connect the GPIB cable.  Its kind of like touching a doorknob one day dry after you walk on the carpet of wool - you will get a 'static' shock when make you initial contact.  Do it at your equipment and laptop often enough and you will damage them.

  A worst case is when the chassis of the laptop is linked to a different potential that the grounded equipment (usually due to strengthening of wiring errors).  In this case there must be a current constant circulating in the commonly known GBIP GND signal ground loop.  Noise and / or damage will be celebrated according to potintial unlike.

  The cure is ALWAYS connect the chassis of the laptop on the chassis of the equipment by an external wire before connecting the GPIB Bus.

  I hope that clarifies the reasoning of 'Warning' that you see in the installation guide.  Kudos to you for reading your guide and to pay attention to the warnings!  Never be afraid to ask when you don't understand warnings

• OfficeJet 6500 connects to the computer with a usb cable.

  He has connected with a usb cable attached with no problems at all, but it has just stopped working suddenly. There is no error message, it does not simply read the printer any port it is connected to. The printer itself seems to work fine - I can make copies with her, and there is no problem I know with the computer. I tried to install wireless, but there need to be connected all first and I tried to buy a new usb cable, but it did make a difference. I'm on a PC - a Compaq laptop. Any suggestions would be greatly appreciated.

  A few ideas:

  1. do not go through a USB hub, plug directly into a port on your PC.

  2. make sure that the USB cable is plugged into the appropriate to the back of the printer port (it will come indeed in the Ethernet port, but obviously will not work here).

  3 restart the printer and the PC.
