It is possible to use Agilent or NI GPIB cards with NI’s VisaNS (Visa Namespace) in Visual Studio .net

For example,

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim pna As New NationalInstruments.VisaNS.GpibInterface("GPIB0::16", NationalInstruments.VisaNS.AccessModes.NoLock, 5000, False) 'this line can be changed to do 488.2, LAN, Serial, USB etc etc.

pna.write("*IDN?;" & vbCrLf)

TextBox1.Text = pna.ReadString

End Sub

End Class
