HELLO,

I Am trying to interface  my GPIB instrument with HOST computer through LabVIEW, unfortunately my GPIB instrument doesnot respond to *IDN? QUERY. Could not find out what is problem with this. Could anyone can help in this regard.

Are you sure the instrument should respond to a *IDN?

Does it say it does in the manual?

[Ameer]

ya the GPIB instrument "doesnot" respond to *IDN? query

Huh? Care to rephrase your answer to my question.

Ameer,

It seems you are a beginner with GPIB instruments. Not all instruments will respond to the *IDN? query. You failed to mention the make and model and that is vital information. Look in the programming manual to see whether *IDN? is listed. If it is not, then simply ignore the warning. If it is listed, then you can start to worry.

Just one addtion: there are even some instruments ( like the agilent 603x powersupplies) which support two different sets of command languages. One set supports the*IDN? query but the other set not.

If the product specification of your instrument says IEEE488.2-compliant (and optionally SCPI language compliant), the instrument must respond to an *IDN? query. Otherwise it may or may not understand the *IDN? query.

In my instrument manual nowhere is written about *IDN? query and anything related to it.

Am using HORIBA MEXA 9000 series vehicle exhast gas analyser. it is pre 1990s model. and CVS system.

My product specification is IEEE488 it uses ASCII 1978 model.
