Programming the PXI VNA

The following tips can help you successfully program the PXIe VNA.

SCPI  (Standard Commands for Programmable Instruments)

The PXI VNA is programmable using the SCPI language. The SCPI documentation is included in this help file.

In the PXI VNA, SCPI commands MUST be sent through either HiSLIP or through the IVI-COM/Labview driver pass-through.

HiSLIP

The PXI VNA software supports the HiSLIP interface for SCPI commands. This MUST be enabled from the Soft Front Panel using the IO configuration dialog. Learn more.

Note: If you can NOT connect with an external PC using LAN (HiSLIP), add a single exception to the firewall – either for the 835x.exe or for port 4880.

IVI-COM / IVI-C / LabView Driver Interfaces

These drivers are the preferred programming interface to the PXI VNA software. The IVI COM driver is extensively documented in its own help file located at "c:\program files\ivi foundation\ivi\drivers\agna\agna.chm". The LabView driver is also documented. Both the driver and help file are included on the CD that was shipped with the product.

Live Soft Front Panel (SFP)

By default, the SFP is NOT visible when using the driver interface to connect to the PXI VNA.  However, both the remote program and the SFP can run simultaneously. This can be useful during development to help diagnose any programming errors. Start the SFP by clicking the "Network Analyzer" icon on the controller desktop.
