Sensitivity: Sensitivity is defined as the combined receive input signal level on both
horizontal and vertical inputs that produces a Null BER Error ratio of 3x10
Output Power: The output power is for a centre channel in Region 1. The output power will
be reduced on the edge channels and may vary if different region codes are selected.
AMOD Threshold: The AMOD threshold is the combined receive input signal level on both
horizontal and vertical inputs that results in the link consistently entering the receive
modulation mode under consideration as the signal level is increased.
System Threshold: Thresholds for all modes except BPSK are for the relevant link
optimization AMOD thresholds. System threshold for BPSK is the RPSK receive sensitivity.
Max Link Loss: The maximum link loss for each modulation mode is derived from the AMOD
threshold for that mode (sensitivity threshold for BPSK) and the maximum Region 1 centre
channel output power. The figures assume integral antennas are used, with gain depending
upon frequency band as follows:
x
23 dBi (5.9 GHz, 5.8 GHz and 5.4 GHz)
x
22 dBi (4.8 GHz and 4.9 GHz)
x
21.5 dBi (4.5 GHz)
x
18 dBi (2.5 GHz)
