Keithley 224 Current Source, 199 DMM Control

Hi everyone,
I can't control some hardwares. Actually, i changed my computer and again install labview, gpib driver etc but i can't control some devices.
Labview connect to Keithley 224 but it can't operate the device.
* Connected to: GPIB0::17::INSTR
-> *IDN?
<- NDCI+0.0000E+0,V+3.0000E+0,W+5.0000E-2«x0D»
I found some topic related my problem but i can't solve that problem. 
i solved this problem in past but i don't remember how i can that. 
About my system;
* NI Labview 2013 64 bit
*Agilent GPIB 82357A USB to GPIB
*Keithley 224 Programmable Current Source
*Keithley 199 System DMM/Scanner 
*Keithley 196 System DMM
*Keithley 2401 Sourcemeter (i can control this device)
*SR530 Lock-in Amplifier Stanford Research System
etc
i attached below some screenshot and my vi's

You'll need LabVIEW 2013 32-bit to work with Agilent 82357A.
You will also need to read http://digital.ni.com/public.nsf/allkb/F7C187DBF09EBE1186256F550065BD32

  • How to control 8 current sources in the same time with labview?

    Hi,
    I'm a French student who have to create a program which is able to control 8 current sources in the same time.the aim is to plug the currents sources in the input of a laser.
    If someone has an idea, it would be very nice to inform me !!!
    Thanks in advance.

    Is it really Tektronik or is it Tektronix. Tektronix is a major test equipment manufacturer. I can't find any reference to that model number on their site, though.
    There are several resources for learning instrument control. One good place to start is http://zone.ni.com/devzone/cda/tut/p/id/4357.
    Assuming that you have a NI GPIB controller for the pc, you will be using the Instrument I/O Assistant or the VISA commands to send/recieve data from the current sources. Without having access to the programming manual, I can't give specifics on what commands you need to send. Your topic mentions controlling them at the same time. Truly simultaneous control is possible in only a few situations. If you have a couple current sources in the same mainframe, you may be able to send a single command to set them all. It will really depend on the commands that the vendor has implemented. With separate mainframes, you will send commands first to one, and then another, etc. Again, depending on what the vendor has implemented, it may be possible to sequentially program all sources to a ready state and then trigger all simultaneously.

  • How to construct current controlled current source

    I wish to check my solution by using multisim,however, i don't know how to construct a circuit that contain current controlled current source. Hope anyone can help me.Thanks in advance
    Solved!
    Go to Solution.

    Thank for your reply...I have tried to construct the circuit already.But the current that i get from calcuation is 254.8mA, and from the multisim, i get 181.819mA,i dont know which part i connect wrongly.Here is the circuit that i done.

  • MULTISIM need help with placing current dependent current source?

    [IMG]http://i56.tinypic.com/ei7a0n.png[/IMG]
    as you can see it is a current dependent current source and has value 2*I(x). i have placed it in a circuit in multisim but i have a feeling i'm doing it wrong:
    [IMG]http://i54.tinypic.com/2ppezj5.png[/IMG]
    and don't worry about the 25-amp resistor at the right it was the load resistor we had to place.

    Hello,
    Well from the first circuit you have there, you are looking for the current source to output 2x curret passing between the 10ohm resistor and the 19v source. So you need to connect that line to the current controller (the square thing attached to the current source), basically running a wire from the voltage source to one end of the controller, then running the other end of the controller to the 10ohm resistor (deleting the connection between the resistor and the source so that they only connect through the controler).

  • Controllable current source

    Hello ,
     I need help in creating a controllable current source using DAQ(PXI-1042). The current range needed is around 0mA to 400mA. Now the current from the DAQ AO pin is very low; around 10mA. How to I get a controllable current of my range? I am trying to use LM317 regulator, but I am not sure about the pin connections. I have attached my circuit diagram here; but that is not working. Can someone please suggest me where am I going wrong? How should i connect the LM317 pins and if there is any other method to get a adjustable and controllable current output? Thanks in advance.

    Hi Shreyas,
    did you even try to look up some information from the internet? There are plenty resources on usage of LM317 as this one!
    To use the LM317 as current source you need to control the voltage between OUT and ADJ pins. Usually this is done using a resistor. In your case you need to use more than just a simple AO of your DAQ board…
    Btw. Do you have any experience in basics of electronics?

  • I need GPIB Driver for Keithley 263 Calibrator/Source Meter using Labview. Can anybody help? Thank you.

    I need GPIB Driver for Keithley 263 Calibrator/Source Meter using Labview. Can anybody help?
    Thank you in advance.

    Hi,
    on Keithley's website is explained :
    "The Model 263 offers a more economical, more precise alternative to the Model 6430 or the Model 236 when used as a low-current source. It is used almost exclusively as a current calibrator."
    This leads to Model 236.... A LabVIEW-driver is available @: http://search.ni.com/query.html?lk=1&col=alldocs&nh=500&rf=3&ql=&pw=595&qp=%2BContentType%3AInstrumentDriver+%2BIDNetManufacturer%3A%22Keithley%22&qt=&layout=IDNet
    Maybe you have to "reconstruct" some parts - but it will help.

  • Current Source

    Hello,
    I want to build a current source controlled by LabVIEW. I was looking at some information and I found that you can make a voltage controlled current source, which we can control with the 0-10 v analog output of my DAQ card. The problem is that I need to generate currents of about 30 A, so these circuits dont work for my needs.
    Do you have any ideas of how to build this current source?  
    PXI 6229, PXI 6232
    LabVIEW 8.2

    You can buy a off the shelf power supply which is able to be controlled by an analog voltage for current limit. Set the power supply to the max. allowed voltage and the anlaog control to current limit. Sometimes you need an isolated analog amplifier between the DAQ-card and the power supply to get them work correctly.
    Take a look a the specifications fo the power supply to meet all requirements johnsold was talking in his questions.

  • Independent current source with set of conditional equations

    hello,
    I'm trying to build this customized block. it has a bunch of fixed value elements (2 resistors and 2 capacitors) and a current source. the current source needs to have a value that's based on a conditional expression expression:
    Id = something; for Vgs < something, Vds < something
          something else; for Vgs < something, Vds > something
          something else; for Vgs > something
    I have the equations and I have all of the parameters, but I have no idea how to implement the conditional statements for the current source. I'm not even sure where to start. thank you very much for any help.
    r.

    rob_xx17,
    These are Analog Behavioral Model sources, for current, ABM_Current, and also ABM_Voltage for voltage.   They are very useful to set up a series of conditions (relative to other values within the circuit) to generate appropriate controlled current and voltages.
    The ABM sources can be found in Master Database -> Sources -> CONTROLLED_CURRENT_SOURCES  (or CONTROLLED_VOLTAGE_SOURCES).
    Here is an example of using them with a nested if/then conditional.
    In this example I1 is depended on the voltage at net(1) - which is simply V1.
    So in this example, for I1 you have 3 states (dependent on V1):
    a) V1 > 4V, I1 = 1 (Amp)
    b) V1 <= 2.5V, I1 = 0 (Amp)
    c) V1 greater than 2.5V and 4V or less (inclusive), I1 = 0.1 * V1 (Amp)
    Here is a look at the behavior of I1 as V1 varies from 0 - 5V and back from 5 to 0....
    To specify a single ended voltage referenced to ground net(0), you just specify V(netname).  
    To specify a differential voltage, you would state V(net, net2)...

  • How to read a current line in table control in dialoug program ?

    How to read a current line in table control in dialoug program ?
    this code required to provide F4 help.

    Hi,
    You can use the variable <tablecontrol>-Currentline as Ebus says but there is a problem with this.Suppose there are 10 records in the table control with only 5 records visible then when u press a page down and press F4 the first record in page 2,  <tablecontrol>-Currentline will have value of 1 instead of 6.So you will need to write a small logic for that.
    index = ( <tablecontrol>-topline - <tablecontrol>-currentline ) + 1.
    read internal table itab at index.
    Hope this helps.

    Your page code suggests you're using the javascript method to embed the QTVR's and you even have a link to the proper QuickTime .js file on your server. But your page code is incorrect (object/embed) for that file to work.
    Your source file (at the link you provided) is 800X600 but you've used the "tofit" tag to reduce its size. A 600 width "tofit" would need 450 for the height. But you've set it at 345 (your code above). This would cut things off.

  • Current sourcing problem (AT-AO-10).

    This is odd. A month ago, I had no problems sourcing current
    (4-20mA). Due to a leak developed in my furnace, I haven't been running
    my current source for a while. Today, I get everything back together, and
    all of a sudden, my AT-AO-10 will not source current. I pulled it out,
    checked the fuse (F2), and it was okay. I tried different channels. I
    disconnected my loop, and put in a loop that consists of only a 9V battery
    and my multimeter, and I still get nothing.
    I've done all I know to do. I can't figure out this one for the life or
    me. Has anyone ever seen anything like this? If so, can you tell me what
    I might try?
    FWIW, I am using a CB-50LP to convert my 5o pin ribbon to separate
    connectors.
    Thanks,

    Hello;
    You didn't mention what version of the NI-DAQ driver you are using over there. Anyway, my suggestion to you is to uninstall the NI-DAQ driver you have installed, remove the board, reboot the machine, download and install the latest NI-DAQ version (6.9.3) from NI web site.
    Try the installation with the new driver, and if that is still not working, the best bet is to try the same installation on a different machine to double check if the hardware is not defective.

    The internal current source of the 4351 should be 25 µA. Actually, initialization using the measurement and automation tool gives 25, but our application will give us 29. How come? The card is actual "initialize" at 2 places in the code. The first time is for setting some I/O directions and the second for temperature acquisition. I joioned the code. THanks

    Are you reading from more than one input?
    These devieces are very acurate but dog slow. The more channels you scan through, the slower you can read to high precision. Using auto-zero in-between gives you better readings.
    Do your inputs look right using MAX?
