As defined in the Bluetooth Core Specification v4.0 Volume 6: Core System Package (Low Energy Controller Volume). 2. Wanted signal level at PIN = -67 dBm. One interferer is used, having equal modulation as the wanted signal. The input power of the interferer where the sensitivity equals BER = 0.1% is presented. 3. Wanted signal level at PIN = -64 dBm. Two interferers with equal input power are used. The interferer closest in fre- quency is not modulated, the other interferer is modulated equal with the wanted signal. The input power of interferers where the sensitivity equals BER = 0.1% is presented. Symbol Description Min. Typ. Max. Units Test level |
