A little tool for various calculations revolving around PSK and QAM modulation schemes commonly found in ENG, SNG, and BAS applications. Useful for bandwidth calculations in satellite (VSAT) and terrestrial broadcast applications. The calculator takes factors such as Forward Error Correction (FEC) and roll-off values into account. It’s also extremely useful for amateur radio operators wishing to deploy digital modulation schemes (DATV, etc.).

Very useful calculator. I was trying to get Mbps from number of Msym/sec at 256QAM on my cable modem, which this tool doesn’t support, but that’s okay. It helped me understand enough that I could figure it out on my own. Thanks!

Hey been, took me 7 years, but I added 256 QAM functionality now.
