Input Triggers from GPIB with LabView

[Ian Forbes]

Hi all,
I am new to LabView (few days...)

I use LabView 5.1 with a GPIB interface, and a KEITHLEY 238 current source
measure unit. The detector is moved on a X-Y table with two stepper motors,
controlled by a Windows 95 software.

I would like LabView to record a measurement from the current source
measure unit each time the current source measure unit sends a trigger
through the GPIB interface.

I tried to use VISA sessions and "Wait for RQS.vi" to make LabView wait for
an input trigger from the GPIB, but it doesn't work..problems with VISA
class... What VISA class should I choose?

Do you think this is the best suited method for my application?

Thank You!
