Trigger Programming Example
This example illustrates how to set up and trigger a voltage and
current change. The voltage is measured before and after the trigger.

Dim IDN As String
Dim IOaddress As String
Dim ErrString As String
Dim msg1 As String
' This variable is used to monitor the status
Dim stat As Long
' This variable controls the voltage
Dim VoltSetting As Double
' This variable measures the voltage
Dim MeasureVolt As Double
' This variable controls the current
Dim CurrSetting As Double
' This variable represents the trigger current setting
Dim trigCurrSetting As Double
' This variable controls the triggered voltage setting
Dim trigVoltSetting As Double
' This constant represents the register value for Waiting for Trigger

' These variables are necessary to initialize the VISA COM
Dim ioMgr As KeysightRMLib.SRMCls
Dim Instrument As VisaComLib.FormattedIO488
' The following line provides the VISA name of the GPIB interface

' Use the following line instead for LAN communication
' IOaddress="TCPIP0::141.25.36.214"
' Use the following line instead for USB communication
