Agilent 82357A USB to GPIB (non visible by VISA)

[Bart1994]

Hi,

I am currently runing kubuntu, linux version 3.19.0-30-generic. KDE plasma version 5.2.2. And i am tryin to use Python to communicate with a  'Maturo Control Unit' (or MCU version 1.30). In orde to do so i am using Pyvisa (version 1.5) and a Agilent 82357A USB to GPIB. When i am using the terminal i can send and reseive commands from the MCU. But when i use Pyvisa's resource maneger the Agilent 82357A USB to GPIB with the MCU connected does not appear. Pyvisa does work. Because ive used it in the past to connect with a spectrum analyzer using TCP:IP.

How can i make Pyvisa show the Agilent 82357A USB to GPIB connected to the MCU?

python 3.4.3:

----------------------------------------------------

>>> import visa
>>> rm = visa.ResourceManager()
>>> rm.list_resources()
()

I'm unsure of why you are posting here. You aren't using any NI hardware or software. Check with Keysight about their GPIB driver and your version of Linux.

Hi

I have same problem. Could you share it with me?

You'll need to talk to Keysight (formerly Agilent) to see if they have linux drivers for the USB-GPIB adaptor.

Sorry it has been a long time since i worked on that internship. I believe use import GPIB in order to get it working. I hope this helps.

import gpib

#--------------------------------------------------------------------------------------------------------------------------

class GPIB(object😞

    def read(instrument):

        device = gpib.dev(0,instrument)                                     #Maakt verbinding met de maturo control unit ()

        responce = gpib.read(device,8)

        #print(responce)

        return responce

    def write(data,instrument):

        device = gpib.dev(0,instrument)                                     #Maakt verbinding met de maturo print(device)

        command = data

        gpib.write(device,command)

    def GPIB():

        pass
