Has anyone been successful in using Prologix GPIB USB converter on labview

[seej]

Though I have seen various comments about prologix but i'll like to know how far the users are able to establish good handshake with their equipment in labview via prologix gpib-usb.

Nevertheless my equipment which is an agilent pna e8362b might be a different case, I will be happy to hear from people that are using or have used similar equipment.

Cheers

We have been working on the same thing but I am not taken exact commands from manuval. i am looking for help that can you provide any good manuval for selecting commands. My project is like this.... LAbview---->prologix gpib-USB controller------>HP 4142b.

Can provide any good manuval for me for communication.

Well, you have to take the 'exact commands' from the manual. You can't make them up. Search Agilent's site for the manual. For the Prologix, you can help and examples from their web site.

I was actually seeking out solutions and wasn't offering one. Sorry if my earlier posting was not clear enough...I want to learn from people that are using prologix GPIB USB on labview because I have not been able to get mine working as should be(probably using the right and acceptable commands). I read that CR/LF should be appended at any write command..I did exactly that but yet to see any effect.

Attach your code. There are a couple different ways to append termination characters and several incorrect ways. You may be using an incorrect method.

Find attached..This is the basic configuration commands i sent with an unrecognised command response

[Dennis_Knutson]

That is not LabVIEW code. What does the text file have to do with anything? Is the file something you are attempting to read?

[seej]

No. I wasn't trying to read the file.

I tried writing those commands into instrument I/O assistant(write parameter) and also in MAX viWrite visa test panel

[Dennis_Knutson]

I give up. I asked you twice to post your code and you have not done that. I'm posting from my phone and I don't want to waste any more of my time or battery.

Incorrectly using termination characters is a common mistake. Search the forum for the solutions

 I started with example given in prologix. I have attached example VI.

I started with query command *idn? in 'string to send' ,front panel.  when I run Vi it has to get the same command  *idn? in 'return string from device' as device means here i created 'U' loop with data pins using jump wires, but i am not getting.
