• 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.

  My desktop icons have a blue circle with a white question mark hide them.

  These are icons by programs such as Norton 360 backup and are used to indicate certain conditions such as the status of the backup. You must go into the program generating overlays and disable this setting. In the case of Norton that would be settings in the main window and then uncheck the backup status overlays.

• Connection ethernet or GPIB with Keithley 2612

  Hallo

  Here's my situation:

  I'm relatively new to LabVIEW programming and want to install a configuration of measurement with LabVIEW and a SMU double Keithley 2612.

  If I m work myself through Labview Beginners Guides and how to connect a measuring device with the first simple LabVIEW program.

  Since I Don t own a GPIB-USB adapter for the moment, I was thinking of using Ethernet for the EMS connection that gets ist own IP address. The connection to the PC works and SMU SMU ethernet can be remote controlled.

  Here's my problem:

  I can´t find (usable) guides for the installation of LabView via Ethernet.

  My 500 pages book 'Introduction to LabVIEW' (as of 2009) doesn´t have even a hint for an ethernet connection, while the GPIB, RS232 and CAN are covered pretty well.

  Here's my question:

  Should I continue to try to get LabVIEW working on Ethernet, or would it be better to buy a new adapter USB GPIB.

  Does anyone know good Howto for creating Ethernet connections?

  Should I just the bad 'Introduction to Labview?

  The use of Ethernet has disadvantages compared to the GPIB-USB?

  I'm happy to answer additional questions.

  Thank you.

  Download the Labview driver for the series of 26xxA from Keithley web site.

  For a Visa resource string use something of the form: "tcpip::aaa.bbb .ccc. ddd::instr" where aaa.bbb.ccc.ddd is the ip address of the instrument that you can get through the façade or run MAX and auto-le discover.

  When you finally get a USB-GPIB converter all you have to do is change the resource in the form of gpib string: GPIB::XX:instr «»

• stop character during the IV sweep with keithley 2600

  Hello.

  I have a labview code to make the IV scans on a solar cell.

  When I sweep V and I measure, it works great every time. Totally reproducible results.

  When I I sweep and measure V, I get randomly 410 interrupts with the vi printbuffer() when playing back the results.

  On the edge of survey error, I find the following details of the error.

  WARNING 1073676293 was held at VISA read in KE26XX.lvlibrint Buffer.vi-> sweepiv_test_2600.vi

  Possible reasons:

  VISA: (Hex 0x3FFF0005) the termination character was read.

  I disabled the stop character in him intialise Keithley 2600 vi, but the problem persists. The strange thing is that the code for the dredging of the V is exactly the same for I sweep (with obvious switches in the source and measurement).

  It seems that the levels of measurement/source are eventually go out of scope and causing the weatherstripping to end at the beginning. But even when I force ranges to a level that would deny such a problem, I always get the error intermittently.

  Any help would be greatly appreciated!

  You can change a property for the stop character node and allow stop character in port VISA.  It's under settings based on the Message.  However, I have not work with GPIB to know how he handles things rather than serial ports.  I don't have your Keithley VI to find out what's going on inside of them.

• OR VISA with Tektronix TDS7404

  Hello world

  I have problem connecting to the oscilloscope Tektronix TDS7404 via Ethernet of LabView. The driver is installed, but when I open the VI example came with the driver,

  I need the VISA name. If I leave the field blank, I get an error:

  1073807343 error occurred while opening VISA in Tektronix 7000
  Series.lvlib:initialize. VI-> Tektronix 7000 series gain Waveform.vi

  Possible reasons:

  VISA: (Hex 0xBFFF0011) insufficient location information or the device or
  resource is not present in the system.

  How can I configure the VISA for this scope?

  It is connected to the PC via a switch, ping for the works of scope, I can see the hard drive of it also.

  I use LabView 2010 SP1; I do not see the scope max.

  Thank you.

  Problem solved. Among device drivers has not been installed. Not the high level (VISA drivers), but the low level drivers. The TekVISA server on the scope did not work as well. Strange that LabView has not complained about these directly, just did not see the scope.

• Name of resource issue VISA with Hameg HMS1000

  Hello

  I have a HAMEG HMS1000 Spectrum Analyzer and I want to communicate with him using NI VISA and SCPI commands.

  First, I created a driver for my device with the information provided here: http://www.hameg.com/0.563.0.html. my device showed in under «NI-VISA USB Devices» device manager

  The problem is when I run the application NEITHER MAX I can see my camera and communicate with them using 'PANEL TEST of VISA's ', but when I switch to labview, visa resource name does not display the name of my device.

  I did something wrong? Help, please

• Will be performing tasks VISA with a data acquisition (Dev1) in a VI block tasks with the second DAQ (Dev2) VISA in a second VI?

  Hi all

  I have two functional screw a loop a set of read and write tasks with device 1 (NI USB-6008).  The second loop a set of writing with device 2 (another NI USB-6008) tasks.  2 VI has a massively slower than VI 1 time scale, which means that it must run in a separate loop.  Otherwise, VI 2 was created by copying and modifying 1 VI and variable names actions with him (though not, for example, global variables).  The two screws are meant to run at the same time on the same PC.

  However, if VI 1 is running at the same time as VI 2, any read operations or in writing to 1 VI 1 device are executed - but the VISA read and write operations to a serial device work.  When VI 2, all VI 1 functions work fine.

  Although I configured channels for tasks using the GUI DAQmx, I execute tasks using reading DAQmx write commands and have correctly defined the task 'create' and 'stop the task' live out the beginning and the end of my loop, respectively.

  Does anyone have suggestions for what could be the cause?  My thoughts so far:

  a. maybe it's some conflicts in the names of variables in memory between the two screws?

  b. LabVIEW for some reason any cannot read and write two devices on two separate screws?

  should c. I avoid to use DAQmx to configure these tasks (a sort of memory)?

  I know I can make it work if I have all together in a single massive VI, but for my application, it is much easier and better to do them in two separate screws.

  Thank you in advance for your help!

  In case anyone wondered, I found the solution:

  When I copied the original code for a new VI, it turns out that the structures of loop timed in the new VI had the same object name in the delivery structure of LabVIEW as timed in the original VI loop structures.  This prevents effectively regardless of the VI was executed the second execution of the timed loop.  (The serial number read/write suite to work because he was in a different timed loop.)

  I found this error when I ran the VI in execution of highlight mode and noticed that the output of 'error' on the timed loop flashed.  When I plugged it on my error stream, I found error-808, which explains the above problem.

  I have it set by right-clicking on the timed loop, change to a while loop, then change to a timed loop and plug the broken wires.  LabVIEW gave the new timed loop object a new name, and all was well in the universe.

• Communication of visa with Agilent 35670 A dynamic signal Analyzer

  Hello

  I'm working on a project that is to use a dynamic Agilent 35670 A and LabView 7.1 Spectrum Analyzer. Use the 35670 I downloaded the corresponding and registered in the libarary INSTR 7.0 LAbView instrument driver as should.

  All the downloaded drivers require the instrument to communicate through VISA which is very good.

  Now, I turn on my instrument, open Measurment & Automation explore and search for devices. Research has managed to find the device at the address (12) so I go to my Labview program and add a 'VISA Rescource name' control which should also the device in the menu drop-down list...

  However, all it lists is the GPIB card to the address (0) and another address (26), I don't know where his acquired address (26) since there is no other instrument connected. There is no sign of address (12)...

  Now, I check all my cables and connections and return to Measurment & Automation Explorer and "Analysis of the Instruments" and the message that no instrument is connected...

  I try a few times but to no result so I was wondering is there a problem with the VISA for the Agilent 35670 communication (this could be a matter of Agilent also?)

  Thanks Dennis,

  I have tried a few different things... changed the cables, used another computer with GPIB card, but it doesn't improve anything.

  Then, I tried the connection GPIB-USB-B, which required and update to 2.2 OR-488, and the updated version seems to have solved the problem.

• Serial communication error VISA with LUDL stage controller

  Hello

  I'm trying to control a micro-positionnement made by Ludl stage. The model is Ludl MAC2000. It seems that the RS232 comunnication is implemented because I can talk to the controller using HyperTerminal. However, when I want to do the same thing through Labview, I can't answer the controller at all. The vi is roughly the same as the visa basic read/write in the example. Looks like a very similar problem in this post:

  http://forums.NI.com/T5/instrument-control-GPIB-serial/visa-serial-communication-problem/m-p/567065#...

  But the trick of nature of endpoint does not help in my case: I tried to toggle the termination character setting in the property node and different combinations of '\r', '\n' as termination characters, but nothing has worked so far.

  Seems to me there is some difference between the interpretations of the same order to Hyper Terminal in Labview. But I just can't understand what it could be.

  Anyone with a similar experience could give me some comments/suggestions? Thank you very much!

  Another difference between hyperterminal and labview is the speed of sending characters.

  LabVIEW breaks out the whole string to the controller

  HyperTerminal is this character by character. So much slower and slow the controller can be affected by this.

  You could add a loop around the writing of visa (to make it easy convert the string into a byte array outside of the loop and convert it to a string inside and you have a shipment char by char in LabVIEW

• Communication of VISA with connected USB GSM modem using a protocol AT

  Hello, I am writing an application that should send sms messages.i have a connected USB GSM modem that supports the PROTOCOL. The modem works by using its own software and the HyperTerminal.I have used VISA driver development Wizard to create the .inf file. The device is now recognized and registered to the MAX. However, I can't understand how to code the commands and read the responses using write VISA and VISA read. Thanks for the help, Dima

  The last thing you should have to do is create an INF with the wizard. Remove completely and the compiled version. What you want to do is to use the inf file supplied with the device which a serial port to the BONE and makes it usable with Hyperterminal. It should appear in MAX as a serial port. Once you have restored all the way it is, then you can start with the examples of series and writing to it should work as it did in Hyperterminal. In other words, simply send the chain of command.
