How to acquire in the same moment datas from differents channels on Electronic Load?

[Auto_Bert]

Hi all!!!

I´m using a DC Electronic Load serie N3300A from Agilent and I connected 3 modules in parallel to increase the current drawn from the source. So, It´s possible via GPIB send one single command to EL and read from these 3 channels datas in the same time? Until now I only found how to make the measurement with a single module or more modules in sequence. Thanks!

Greetings...

Maybe you can trigger all three devices to do a measurement on a GET (Group Execute Trigger) that is a special command on the gpib bus.
But it has to be implemented in the powersupply to listen to this and not all systems support this.

Ok, but which kind of query should I use to receave these measurements to the computer? I just can address one channel each time. And to get these datas I must read from all modules in the same moment. Is it possible?

Best regards.

The group Execute Trigger triggers the instruments and after that you can read out the instruments each after other.
But only if they support GET
