Problem in shoing correct identication number of instrument

[BARIK]

Dear Sir/Madam

                        I have connected GPIB to the EG&G lock in amplifire. Then I scan the instrument using Measurement and Automation analyzer to check the instrument number? But I get a different number everytime i scan the instrument. For your better understanding to my question, I have attached a file and rounded the identification numer, which chaged everytime i scan. Can you please give me a solution to this problem?

Thank you

with regards

Barik

Th lockin does not give an ID on the normal ID question (it was already old when that was standardized). 

Instead it is giving the result of a reading. That is why it sems changing.

Hi

   Thanks 4 reply. I am able to identify the GPIB address, but it is not showing instrument name. It is showing like +00000, +00000. This number keeps on changing. I also tried to make a programme and start running the programme. However, the programme just stuck after initialization. Plz help me to get rid of this problem

Thanks in advance

The fact that MAX does not display an instrument name is not important. As Albert said, the instrument does not support the *IDN? query. You simply ignore what is there.

Unless you attach what you wrote, no one can help you fix a problem. Obviously, any code that contains a *IDN? query is going to be invalid.

Hi

   Thanks for reply. If you see the attached file, u can know that the instrument is not responding even after giving a correct gpib address.
