Cal Factor Table:
Frequency (point ‘0’) 4 - 32 bit fixed 0 to Fhpb*
(2^32)
None Fhpb = Freq Hz per bit
Cal factor (low power)
[a]
2 - 2.14 0.25 to 3 None Power (in watts) is divided
by this value.
Cal factor (high power)
[a]
2 - 2.14 0.25 to 3 None Power (in watts) is divided
by this value.
These table entries are repeated as shown for each frequency point
