recommended to add a 2 dB safety margin to compensate for possible
measurement inaccuracy or variance in the link quality.
NOTE
The SNR measurement at the AU is accurate only when receiving transmissions from the
applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data
transmission.
When the Adaptive Modulation Algorithm is disabled, this parameter will serve to
determine Fixed Modulation Level used for transmissions.
The minimum value for the Maximum Modulation Level is defined by the Sub-
Band in use.
The maximum value for the Maximum Modulation Level is defined by the Sub-
Band in use and the HW revision of the unit. Units with HW revision A support a
maximum value of 7, while units with HW revision B and higher support a
maximum value of 8.
For information on how to view the Sub-Bands supported by the unit and the
supported parameters’ values and options, refer to section 4.2.2.4
