European countries. The following testing has been
completed:
Test standard ETSI EN 300 328 V1.7.1 (2006-10):
• Maximum Transmit Power
• Maximum EIRP Spectral Density
• Frequency Range
• Radiated Emissions
Test standards ETSI EN 301 489-1:2008 and ETSI
EN 301 489-17:2008:
• Radiated Emissions
• Electrostatic Discharge
• Radiated RF Susceptibility

(RFCON3 0x203) cannot exceed -14.9 dB. This is
to meet the requirements of ETSI EN 300 328
v1.7.1 (2006-05), Maximum e.i.r.p. spectral
density limit, Section 4.3.2.2, “For wideband
modulations other then FHSS (e.g., DSSS,
OFDM, etc.), the maximum e.i.r.p. spectral
density is limited to 10 mW per MHz”. The output
power of the MRF24J40MB module, at this setting
with the PA enabled, is 9 dBm.
