VSWR VS. PAD
This program lets you calculate the VSWR you get when a resistive pad is inserted ahead of a high VSWR load - Case 1. Or, it lets you determine the size of T-pad or Pi-Pad required to reduce a given VSWR to a specified lower level - Case 2.

Let's assume we have a load VSWR of 5.
If we insert a 3 dB pad ahead of the load, what will the input VSWR be?
Choose Case 1 by typing a "1" at the prompt above and then press <Enter>.
Answer the next two questions about load VSWR and pad size by entering "5" and then "3." Press <Enter> after each entry.
Here is the output calculation:
VSWR in = 2.004
