The Impacts of RE102 Exceedances on a Received BPSK Satellite Signal

During a RE102 EMC test campaign, several RF receiver notches normally exist, with low levels, over the frequency range of this test campaign. In this case, it is desired not to have any exceedances within any of the RF receiver notches. However, when an exceedance occurs within a given RF notch, it must be determined if this exceedance increases the bit-error-rate of the received modulated carrier or is negligible where no further countermeasures are required. This paper describes a simplified approach for characterizing exceedances within an RF notch and depends upon characterizing the impact of the exceedance on the received envelope of a BPSK carrier that then ultimately affects the received differential eye pattern and associated bit-error-rate (BER).
