VNA SFP Launcher

The VNA SFP (Soft Front Panel) is unique in that this software IS the firmware that runs the hardware. It does not send programming commands to the instrument, but instead communicates directly with the module hardware. It is a complete, FULL-FEATURED software package. This is a subtle difference, but has implications on how you will configure and connect to the VNA modules.

How to start the SFP Launcher (All PXIe/USB VNA)

Note: Download and install the latest version from http://www.keysight.com/find/iolibs.

Note: (P50xxB/P937xB/P938xB) When the USB VNA is not detected, use the latest version of the Thunderbolt 3 driver and BIOS of your PC and execute the windows update.

Click on the host controller desktop to start the VNA Soft Front Panel (SFP).

“VNA Simulator” and the other modules cannot be selected simultaneously.

Select the modules to comprise the VNA.

Note: (USB VNA) When the connected unit is not displayed, reboot PC.

Function	Description
Show dropdown menu	Select Instruments and Modules, Modules, or Saved Instruments. A list of the displayed Instruments and Modules is filtered by the following selection mode. Instruments and Modules – shows both of Saved Instruments and Modules Modules – shows the supported modules found through VISA discovery Saved Instruments – shows the name of saved instruments (which are defined by saving a configuration into IVI Configuration Store)
Help	Open Help
Run	Launch SFP with the configuration of the selected instrument. Open the simulator mode setup dialog if “VNA Simulator” is selected.
Save Connection…	Open “Save Instrument Connection” dialog. The configuration of the currently selected modules is saved into IVI Configuration Store as the specified name. Note: When you encounter the error "IviConfigServer.IviConfigStore.1: Serialized failed..." at clicking "save", Run the VNA SFP launcher as administrator. Add a write permission to the iviConfigurationStore.xml file after the IO library installation.
VNA Simulator	The typical usage of Viewer Simulator is to see the SnP data without an unit connection. Also you can see the operation for some limited softkeys without an actual unit. Select the desired product and option to execute the VNA simulator. Learn more on Simulator
Delete Saved Connection… (When one of the saved instruments is selected in the displayed list, “Delete Saved Connection…” button appears instead of “Save Connection…” button.)	Delete the selected instrument definition.

The launcher can be executed from Keysight IO Libraries (Keysight Connection Expert).

Saving the following script as .bat file allows you to launch the firmware without the module selection. If you launch multiple module, put the VISA address with comma separator.

Troubleshooting Tips

Symptom: The launcher does not respond. Then, after few minutes, the "Failed to retrieve model number from VNAParser.exe. application will exit." will be displayed.

Solution: The .lic file for floating/USB portable licenses should be installed on Keysight License Manager 6. However, it was installed on Keysight License Manager. Delete the .lic file from C:\Program Files\Agilent\licensing\.
