HP 6030a GPIB-USB connection

[sharinganez]

Hi all, i have a Hewlett Packard 6030A System Power Supply.

I wish to use this in Labview for voltage/current settings and measurement as well.

The connection i am using is 

Hp 6030a -> GPIB -> USB -> Labview

First, i have created USB raw driver for the connection using NI VISA Driver Wizard.

Then, I've tried the following labview code to read back the model series, but seems like cant get it connected.

Please help. Any steps are missing or am i doing it wrongly?

You doing everything wrong by using the VISA wizard. Where did you get the idea that you had to use that? Undo everything you did and simply install NI488.2 and NI-VISA. The GPIB contoller should be visible in MAX - and not as some goofy USB device like you have now. There are instuctions on installing and verifying the driver. Follow that and then follow the instructions on detecting your instrument. Your VISA resource name should be something like GPIB0::address::INSTR where address = actual address of the instrument.

Hi Dennis,

The cable i am using is a GPIB - USB

the GPIB end is connect to 6030a while USB end is connect to my computer

so i thought its a USB raw driver.

Please advice.

As for my case, should i use a GPIB control for Labview?

Or a VISA control will do?

Use the driver instead of writing the code yourself.

The driver i get from Agilent website is for GPIB connection

while now i am using GPIB to USB connection

Thats why i am stucked here...

Please help..

i attached the Driver which i downloaded from Agilent

its not compatible with my connection

You aren't making any sense to me. If you have an NI GPIB-USB device, install NI-488.2 and NI-VISA after you have undone all of the VISA wizard nonsense. The only thing you did with that was turn your controller into a useless piece of junk. I already told you this once. The windows drivers make the device work as a GPIB controller and it is irrelevant whether it is a USB, pci, etc, connection to the pc.

If you have a GPIB-USB controller from Agilent, follow their installation instructions.You simply cannot makeup your own installation procedure as you have done uo to now.

Hi Dennis, sorry as i am quite new to Labview Instrument control.

Credit goes to you as i have managed to communicate with my instrument now.

Appreciate it! Thanks !
