LNA gain: maximum, filter bandwidth: 135 kHz, data rate: 9.6 kbps, AFC: switched off, FSK deviation: ±60 kHz, V
The measurement was done according to the descriptions in the ETSI Standard EN 300 220-2 v.2.1.2 (2007-06), section
4.3.3. and 4.3.4., referring to EN 300 220-1 v2.1.1 (2006-04), section 9.
The ETSI limit given in the figure is drawn by taking –104 dBm at 9.6 kbps typical sensitivity into account, and corresponds
to receiver class 2 requirements (section 4.1.1).
