A Multiport S-Parameter Plotting Utility
Dave Watling , of pSemi, sent me a note about the company's new "sNp Viewer" multiport s−parameter plotting software that is available for free downloading on the pSemi website. It is provided as an executable file that installs the Runtime Vee (Keysight) framework needed for the program's operation. Look for the sNp Viewer icon to appear on your desktop (not in the Start menu) when installation is complete. You can drag the icon into the Start menu afterwards. My guess is this was a tool developed for internal use by the engineering staff and it turned out so well that they decided to make it available to everyone; it is quite handy.
The example screen shot at the right uses the pSemi* PE42430 UltraCMOS® SP3T Reflective RF Switch, which is a 4-port device with a .s4p data file extension. I wanted to use a device with more than just two ports. The plots would get really busy if the PE42412 UltraCMOS® SP12T RF Switch was used with its .s13p data files! Shadowed items on image are things I added for additional information.
* The datasheet shows Peregrine Semiconductor, pSemi's former handle.
