Multiple GPIB Instruments

Hello,

 

My computer can successfully control a multimeter (agilent) using labview via GPIB. I used the corresponding labview driver for the instrument. However, I am writing to find out if it is possible to control multiple instruments to take certain measurements simultaneously. I want to use about 4 multimeters to measure 4 different parameters. Can I do this still using the drivers or is there another method.

 

I am connecting the instruments to my computer in a linear connection. i.e. I connected the first GPIB cable to the instrument and then I connected the second GPIB cable for the second instrument onto the first one and so on.

 

I have  searched some of the previous posts but I did not really find anything directly relating to my question.

 

Any information or suggested with regards to approaching this situation is much appreciated.

 

Thanks

There have actually been numerous posts on the subject. What you have to do is issue a trigger so that all instruments receive that and perform a measurement. You would then sequentially read each one. If you have a means to issue a hardware trigger and the instrument has an external trigger source, use that. If they have a software trigger, you can issue a GPIB GET command. This stands for Group Execute Trigger.
