From the developer:
This nifty little tool allows you to convert important Parameters of your RF-system.
If you know the VSWR of your system and you need the Reflection Coefficient simply enter the VSWR and our tool will instantly display the corresponding values for the Reflection Coefficient and Return Loss.
Additionally it will also show the VSWR in dB.
Of course you can also input any of the other measures as the basis for your conversion.
You may want to check out more software, such as Rohde & Schwarz dBCalculator, which might be similar to VSWR.
