a. Narrow Band (In Band) Blocking measurements:
0 to ±40MHz; 1MHz step size
Wide Band Blocking measurements:
30MHz to 2000MHz; 10MHz step size
2000MHz to 2399MHz; 3MHz step size
2484MHz to 3000MHz; 3MHz step size
3GHz to 12.75GHz; 25MHz step size
Wanted signal for wideband blocking measurements:
-67dBm in 1Mbps and 2Mbps mode
-77dBm in 250kbps mode
For Interferer frequency offsets n*2*fxtal, blocking performance are degraded by approximately 5dB
compared to adjacent figures.
If the wanted signal is 3dB or more above the sensitivity level then, the carrier/interferer ratio is indepen-
dent of the wanted signal level for a given frequency offset.
