KEITLEY GPIB-USB device is not recognise any instrument in labview

[ankush26]

Hello, 

          I am doing noise measurement of device with Dynamic Signal Analyzer (DSA) Hp 35670A. I need to automate the measuremnt process with help of labview. I have installed the drivers for DSA hp 35670A by find an istrumnet driver help menu in labview. While doing this labview was showing that DSA hp 35670A is connected to system, since i have connected the DSA hp 35670A to my system via KEITHLEY GPIB - USB 488A connecter. I have also installed driver for KEITHLEY GPIB - USB 488A connecter. But when i try to see the same in NI - MAX it is not showing that the DSA hp 35670A is connected to system. I have also attached the snapshot with the post. It is clearly seen that nothing is seen under the name of GPIB connecter KUSB 488A.So NI - MAX is not detecting instrument. So plase suggest me how to get rid of this problem.

          Thank you.

MAX is normally only for NI devices. Do you also have NI-VISA installed? If so, you can try selecting that and enabling tulip support.

Thank you for your valuable advice. I have done setting accordingly for enabling  tulip support in VISA options. For changing the settings i have reffered post on this forum having link - http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/How-do-I-turn-on-the-quot-Passport-to-Tulip-q... But still i am unable to find my instrument DSA hp 35670A under the name KUSB - 488A in tree of my sysytem -> device and interfaces. Can you please tell me what things i should take into considerations while making use of third party GPIB - USB conenctor in labview for data acquisition.

Thank you.

Unfortunately, I don't know what else to do. I've only used NI and Agilent controllers. Adding tulip support is normally all that you need for Agilent after installing their drivers and making NI-VISA primary. What does Keithley have to say?

If you were able to find that link, you should have been able to find http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/kusb-488-and-LABVIEW/m-p/555644

and also see if http://forum.keithley.com/phpBB3/viewtopic.php?f=83&t=820 is useful to you

You are not using an NI GPIB, so using NI Max to find your instrument makes no sense.

Also enabling tulip support is not needed, the only passport you need to mark on is the NI-VISA Passport for GPIB

The bigger question is what operating system do you have?

Is it 32-bit or 64- bit LabVIEW? If 64-bit, the driver will not work, it is only a 32-bit driver.

Also, what version of the KUSB-488A driver is installed?

Only the latest version is compatible with newer operating systems.

The latest version is 9.2 and can be found here:

http://www.keithley.com/support/data?asset=53029

(also...please do not confuse this with the KUSB-488B, as this uses a completely different driver).

Please ensure that the NI-488.2 GPIB driver is not installed.

If so, uninstall this using control panel programs and features or add/remove programs (it is listed under National Instruments Software).

Once the KUSB-488A driver is installed, check connect your interface and instrument and check for your instrument in the following places:

(1) Attempt to talk to the instrument using the driver

CEC diagnostic: Start->All Programs->CEC488->TRTEST.exe (use the Send and Enter buttons to test writing and reading respectively).

(2) If successful, check for your instrument and interface in VISA intercative control:

NI Visa Interactive Control (Start->All Programs->National Instruments->VISA->Visa Interactive Control) (this should list both your interface e.g. GPIB0::INTFC and any connected instruments, e.g. GPIB0::16::INSTR. If your instrument is listed, you can also try to talk to it too.

(3) If all works, then open LabVIEW and attempt to talk to your insrument using VISA Write and VISA Read commands

Hi Ankush,

Thanks for contacting us . Since you are trying to implement I recommend you give a read to this link http://www.ni.com/white-paper/3702/en/. This link will help you understand about NI-VISA which is used to communicate with third party instruments.

Usually we recommend using the NI GPIB-USB HS  - http://sine.ni.com/nips/cds/view/p/lang/en/nid/201586 - with third party instruments so that you can directly downaload the instrument driver from the vendor and use. However since you are using http://www.keithley.in/products/accessories/ieee/usb/?mn=KUSB-488B

make sure you have uninstalled the NI-488.2 driver. Then install the Keithley KUSB-488A driver (must be version 8.2 or higher).The latest version for the same is 9.2.

The driver does give you NI Compatibility for use with LabView or LabWindows/CVI, etc. The driver will install a KEVICec Visa Passport. Make sure when communicating using Visa that you turn off the NI Visa Passport. You should then be able to communicate to instruments in LabView with the KUSB using either GPIB Read/Write or Visa Read/Write commands.

Since you are using Agilent Technologies 35670A Dynamic Signal Analyzer, kindly install the necessary deriver from the following link : http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=1151. This driver will help you communicate with NI - VISA and use its functions to directly communicate with your DSA in LabView.

You can also see the KUSB and any connected instruments in the Visa Interactive Control utility.

Thank you very much Rikud and Devmaletia for your valuable advice. Thanx a lot.
