NI VISA-Keithley 6514

[DenisDiaz]

Hello everyone,

I have a Keithley 6514 multimeter, and I want to connect it to LabVIEW. I have installed the Keithley drivers and NI-488.2, as well as NI-Visa.

When I open NI max, it recognizes the device but not as GPIB, and NI Visa IC does not recognize it.

Is there any way to get NI Visa IC to recognize it?

Thank you very much in advance.

Denis.

How are you connecting? is it NI USB-GPIB?
Which Keithley drivers are you referring to?

[DenisDiaz]

Hola Santo_13, muchas gracias por responderme, estoy conectando un keithley 6514, el cable de comunicación es un GPIB-USB-B de National Instruments, los drivers a los que me refiero es porque según he entendido necesito un o unos drivers para que el dispositivo aparezca en Ni max y poder usarlo en un programa de labview.

What versions of NI-488.2, NI VISA, and LabVIEW are you using?

Is the Keithley 6514 set up to use the GPIB port? For many instruments, you have to enable the port and set the address before you can talk over it.

[DenisDiaz]

Before anything else, I would like to thank you for taking the time to respond to me.

The versions you asked me about are as follows:

NI 488.2 2023 Q3

NI VISA 2023 Q3

LabVIEW 2023 Q3 32-bit

Yes, the device is configured to use the GPIB port.

What GPIB interface are you using? is it a NI or Keithley product?

[DenisDiaz]

I dont´t understand the question about GPIB Interface.

It is a Keithley product.

Thanks for respond.

Since you use NI-USB-GPIB converter, you need NI-VISA driver installed to be able to use the GPIB to communicate.

Next, for the Keithley 6514 to show up under the NI-USB-GPIB in NI MAX, you can select the GPIB interface and select scan for instruments, this should populate all instruments that respond to IDN query.

Scan for instruments also tells you the address of the instrument, now, you can use this to communicate either using the VISA interactive panel or use NI-VISA driver with LabVIEW or any language.

When you download LabVIEW driver for 6514, it refers to the VIs that contain the SCPI command formatting and parsing as per the 6514's manual and communicate through NI-VISA functions.

I see you got your answer but for future reference Keithly, Agilent/Keysight and maybe a few other USB-GPIB interfaces need a special setting (Tulip driver) enabled in NI-MAX that is disabled by default to operate with LabVIEW and NI-VISA

[DenisDiaz]

First of all thanks for responding RTSLVU,

If I use another GPIB adapter in the future, I'll look into the Tulip driver.
