4.4 BLE PER vs Blocking Requirement (ETSI EN 300 328 V2.1.1)

Test steps:

  1. Wanted signal level is set 6 dB above the sensitivity level for the selected operating frequency (2402 MHz and 2480 MHz) according to the result from Section 4.2 and Section 4.3.
  2. Apply a TX CW interferer at 2300.0 MHz to the DUT with increasing power level until PER goes above the specified 30.8% level for BLE.
  3. Repeat step 2 for 2380.0 MHz, 2503.5 MHz and 2583.5 MHz

As can be seen in Table 5, Figure 12 and Figure 13, the CC2650 are well inside the requirements specified in ETSI EN 300 328 V2.1.1 when using Bluetooth low energy.
