According to your NI-MAX setting, the Hardware Asset "PSA" configues the GPIB address at "GPIB0::18::INSTR". But your InitClose example opens the instrument directly with VISA address "GPIB0::16::INSTR". Which is the correct instrument address (16 or 18)? Also, If directly passing a VISA address to Initialize function, no logical name is applied, therefore any IVI settings in NI-MAX are meaningless. If you utilize the IVI configuration you set in NI-MAX, the Initialize call must take the logical name you created - "SpectrumAnalyzer".
As for Virtual Name and Physical Name, you do not always have to configure the map of them. You can always use one of physical names for the channel name regardless the mapping. In this case you can just leave them empty in your Driver Session.
