EXAMPLE
Positive
REF LEVEL Offset (KSZ), Sign
REF LEVEL Offset (KSZ), in dB
150
Where bit 6 Byte 36 is MSB and bit 0 byte 37 is LSB of a 15 bit binary
value. If sign bit is 0 (pos) offset is decimal equivalent of binary value/
10. If sign bit is 1 (neg) offset is two's complement of binary value/lO.
Unused
