Creating and Downloading Waveform Files
Programming Examples
' data requirements for file downloads. The waveform data 'IQ_DataVB' is
' downloaded to the signal generator's non-volatile memory(NVWFM)
' " /USER/WAVEFORM/IQ_DataVB". For volatile memory(WFM1) download to the
' " /USER/BBG1/WAVEFORM/IQ_DataVB" directory.
'
' You must reference the Keysight VISA COM Resource Manager and VISA COM 1.0 Type
' Library in your Visual Basic project in the Project/References menu.
' The VISA COM 1.0 Type Library, corresponds to VISACOM.tlb and the Keysight
' VISA COM Resource Manager, corresponds to AgtRM.DLL.
' The VISA COM 488.2 Formatted I/O 1.0, corresponds to the BasicFormattedIO.dll
' Use a statement such as "Dim Instr As VisaComLib.FormattedIO488" to
' create the formatted I/O reference and use
' "Set Instr = New VisaComLib.FormattedIO488" to create the actual object.
'********************************************************************************
' IMPORTANT: Use the TCPIP address of your signal generator in the rm.Open
' declaraion. If you are using the GPIB interface in your project use "GPIB::19::INSTR"
' in the rm.Open declaration.
