Hai, I am working with Visual Basics 2019 to control two devices using GPIB-USB-HS+. I could control one device by following syntax.



Imports NationalInstruments.VisaNS


Dim GPIB_ResourceString1 As String


GPIB_ResourceString1 = "GPIB0::8::INSTR"

mbSession = CType(ResourceManager.GetLocalManager().Open(GPIB_ResourceString),

MessageBasedSession)


mbSession.Write("OUTX 0 ;")


response = mbSession.Query("OUTX ?").
