cies. Note that sometimes the blocking is measured relative to the sensitivity level 104 dBm
(denoted dBS), instead of the carrier –102 dBm (denoted dBC)
Table 2-8.
The ATA8201/ATA8202 can also receive FSK and ASK modulated signals if they are much
higher than the I1dBCP. It can typically receive useful signals at
to as the nonlinear dynamic range (that is, the maximum to minimum receiving signal), and is
95 dB for 10 Kbits/s Manchester (FSK). This value is useful if the transmitter and receiver are
very close to each other.
