Communication between EG prober and Tester

[daveb123]

Hi,

I am wanting to write some LabVIEW to code to test on wafer using an EG prober and other test equiupment, I have only done simple stuff with GPIB so far - my problem is with the communication between the prober and a laptop which is using an Agilent USB-GPIB interface. What I want to be able to do is start the LabVIEW software, then start the prober. The LV code will wait for a test start command from the prober, and then test a device, on completion of the testing of a device the LV code will send a test complete command to the prober and the prober will move to the next device, and so on and so on.... How can I get the laptop/Labview to wait for a command from the prober - is this done with SRQ? Can this still be done
with VISA?

Thanks for your help.

Dave.

The simple way is to use a query command like *OPC? (operation complite query), hopefully EG prober supports this. Of course you can done this with VISA event: VI_EVENT_SERVICE_REQ.
