Symbol Rate Calculator
The number of symbols that are changed in a signal every second is known as the Symbol Rate or Baud Rate. Each symbol can represent one, two, three, four, or more bits of transmission rate data depending on the modulation coding method (MODCOD) being utilized. The rate at which symbols are transmitted is the baud rate.

Bits per Symbol (Modulation Factor)
- BPSK = 1
- QPSK = 2
- 8PSK = 3
- 8QAM or 8APSK= 3
- 16QAM or 16 APSK = 4
- 32QAM or 32 APSK = 5
- 64QAM or 64 APSK = 6
- 128QAM or 128 APSK = 7
- 256QAM or 256 APSK = 8
