MM200 High-Speed Microwave Modem Appendix A
TM086 – Rev. 4.1 A-43
Opcode: <0x229B>
Command demodulator bandwidth
Command Data
<4> Bandwidth Available bandwidth
Note: Command is only allowed in Level 2 User Mode.
Along with the selected interfaces, and the number of
channels, the modem calculates all relevant system
parameters optimizing for robustness (minimizing
modulation).
